description:
The Triassic-Jurassic boundary (TJB) and the early Toarcian are characterized by greenhouse warming, caused by the emplacement of large volcanic provinces. Despite similar trigger mechanisms, the two events differ in their character. Most significantly, the early Toarcian records the genesis of an Oceanic Anoxic Event (T-OAE), while the TJB event lacks robust evidence for widespread marine anoxia and organic matter (OM) accumulation.

Here, we present bulk, isotope, and molecular geochemical data from a continuous drill core, taken in the northeastern part of the North-German Basin that spans upmost Triassic and Lower Jurassic strata (Rhaetian-Toarcian). The sediment archive represents a near-shore environment, proximal to an estuary. This setting at the land-sea-interface was particularly susceptible to sealevel, climate, and environmental change and records the response of a shallow marine environment to major Late Triassic-Early Jurassic climate events.

In contrast to the predominantly OM-lean Triassic-Jurassic strata, the TJB interval and the T-OAE are characterized by increased OM contents, but their compositions differ significantly. At the TJB, increased abundances of soil and land plant OM accumulated under semi-arid conditions in mesosaline and well-oxygenated shallow marine setting. By contrast, during the T-OAE, OM-rich sediments accumulated under short-lived anoxic-euxinic conditions. Development of oxygen-deficient conditions was favored by a high sea level and persistent freshwater stratification caused by enhanced riverine discharge under humid climate conditions. Land plant wax lipid, algal molecular fossils, and wildfire combustion residues further revealed that the TJB and the T-OAE were accompanied by substantial changes in both the continental and marine ecosystems.

description:
Profound climatic and environmental changes at variable timescales are documented throughout the Late Triassic to Early Jurassic (c. 210-170 Ma) and were linked to the emplacement of large igneous provinces, tectonic processes, as well as transient climate fluctuations. Climate and environmental change triggered bio- and geosphere evolution, and impacted on sedimentary archives of marine and terrestrial basins. Most severe environmental change events, involving global carbon cycle and ecosystem perturbations, occurred at Triassic-Jurassic boundary (TJB; c. 201 Ma) and during the early Toarcian Oceanic Anoxic Event (T-OAE, c. 182 Ma).

We here discuss the differential response of depositional settings and organo-facies towards secular and transient environmental change along a basin-margin transect of the NW European Epicontinental Seaway (North German Basin), an expanded and intensively structured shallow shelf sea.

Stable carbon isotope values (d13Corg) revealed diagnostic trends that allow the precise intercorrelation along the transect, as well as correlation with far-apart sites. The TJB and the T-OAE are indicated by prominent negative carbon isotope excursions.

Programmed pyrolysis data indicate spatio-temporal organo-facies trends that on a temporal scale occurred in response to changes in deposition, such as climate and sea level evolution, while spatial pattern reflect basin morphology and paleobathymetry. Marine organic matter is best preserved at anoxic basinal sites, while marginal settings received increased land plant contributions and/or experienced more intense oxic degradation of marine organic matter. Substantial TOC accumulations occurred only in association with the T-OAE during high sea level and were most continuous at basinal sites.

description: Although the relationship between the far-infrared and cm-wave radio luminosities of normal galaxies is one of the most striking correlations in astronomy, a solid understanding of its physical basis is lacking. In one interpretation, the "calorimeter model," rapid synchrotron cooling of cosmic ray electrons is essential in reproducing the observed linear relationship. Observed radio spectra, however, are shallower than what is expected of cooled synchrotron emission. In Thompson et al. (2006), a simple parameterized model is presented to explain how relatively shallow observed spectra might arise even in the presence of rapid synchrotron cooling by accounting for ionization losses and other cooling mechanisms. During the commissioning of the 42-element Allen Telescope Array, we observed the starburst galaxies M82, NGC 253, and Arp 220 at frequencies ranging from 1 to 7 GHz, obtaining unprecedented broadband continuous radio spectra of these sources. We combine our observations with high-frequency data from the literature to separate the spectra into thermal and nonthermal components. The nonthermal components all steepen in the cm-wave regime and cannot be well-modeled as simple power laws. The model of Thompson et al. is consistent with our M82 results when plausible parameters are chosen, and our results in fact significantly shrink the space of allowed model parameters. The model is only marginally consistent with our NGC 253 data. Assuming the Thompson et al. model, a steep electron energy injection index of p = -2.5 is ruled out in M82 and NGC 253 to >99% confidence. We describe in detail the observing procedures, calibration methods, analysis, and consistency checks used for broadband spectral observations with the Allen Telescope Array.

description: Slowing down of the relaxation of the fluctuations around equilibrium is investigated both by stochastic simulations and by analysis of Master equation of reversible reaction networks consisting of resources and the corresponding products that work as catalysts. As the number of molecules $N$ is decreased, the relaxation time to equilibrium is prolonged due to the deficiency of catalysts, as demonstrated by the amplification compared to that by the continuum limit. This amplification ratio of the relaxation time is represented by a scaling function as $h = N \exp(-βV)$, and it becomes prominent as $N$ becomes less than a critical value $h \sim 1$, where $β$ is the inverse temperature and $V$ is the energy gap between a product and a resource.
title: Remaining opportunities in medium-deep reservoirs of the North German Basin – lessons learned from the new development in Schwerin

description:
The North German Basin yields enormous resources of heat in place bound to the Palaeozoic–Mesozoic succession and to fault systems. Early exploration campaigns have identified highly permeable Mesozoic sandstones at depth of <2,300 m with temperatures of <100°C. Despite the fundamental knowledge established by these campaigns, the development of hydrothermal reservoirs remained limited due to considerable pre-drilling risks resulting from uncertainties in reservoir predictions at individual localities.

To minimise risks associated to subsurface uncertainties, an interdisciplinary work flow integrating sedimentological, geophysical, and petrophysical methods was designed to re-evaluate the six Mesozoic reservoir complexes of the North German Basin. Within the projects Sandsteinfazies, GeoPoNDD and mesoTherm this work flow was applied to an extensive database of cores and wireline logs leading to high-resolution maps depicting facies, thickness and quality of individual hydrothermal reservoirs. These maps enable reliable predictions of key parameters, i.e. net-thickness and permeability, on regional to local scales and, thus, make a significant contribution to the reduction of subsurface uncertainties. The potential of these subsurface reservoir maps to increase the utilisation of geothermal energy is demonstrated on the example of the reservoir development at Schwerin, a previously underexplored locality. There, reservoir predictions enabled targeting a highly productive sandstone at 1,250 m depth. The operation combines a conventional doublet system with industrial heat pumps to supply 7 MWth to the local heating grid. The lessons learned from Schwerin demonstrate significant opportunities in medium-deep reservoirs enabling a sustained increase of developments for heat supply in North Germany.

description: We present the recently derived Wolf et al. (2009) mass estimator, which is applicable for spherical pressure-supported stellar systems spanning over ten orders of magnitude in luminosity, as a tool to test galaxy formation theories. We show that all of the Milky Way dwarf spheroidal galaxies (MW dSphs) are consistent with having formed within a halo of mass approximately 3 x 10^9 Msun in LCDM cosmology. The faintest MW dSphs seem to have formed in dark matter halos that are at least as massive as those of the brightest MW dSphs, despite the almost five orders of magnitude spread in luminosity. We expand our analysis to the full range of observed pressure-supported stellar systems and examine their half-light I-band mass-to-light ratios. The M/L vs. half-light mass M_1/2 relation for pressure-supported galaxies follows a U-shape, with a broad minimum near M/L ~ 3 that spans dwarf elliptical galaxies to normal ellipticals, a steep rise to M/L ~ 3,200 for ultra-faint dSphs, and a more shallow rise to M/L ~ 800 for galaxy cluster spheroids.

description:
The U.S. Geological Survey (USGS) has recently published a guideline for processing coastal imagery acquired by unmanned aerial vehicles (UAVs) based on the widely used Agisoft Metashape Professional software (USGS Open-File Report 2021-1039; Over et al. 2021). The guideline aims to improve the quality of photogrammetric reconstructions by iteratively removing low-quality tie points based on different cleaning parameters. However, the improvement procedure is iteratively performed and requires permanent attendance of the operator. Furthermore, the different cleaning steps are executed on a trial-and-error basis, adding up to the overall attentiveness required.

To minimise the time expenditure necessary for conducting the cleaning procedure and to provide a frame for the reproducibility of photogrammetric product derivations, we have compiled a python script to automate the tie point cloud optimisation as detailed in the USGS report. The graphical user interface of the script allows non-expert users to adjust important cleaning parameters, such as maximum reconstruction uncertainty, minimum projection accuracy and/or maximum reprojection error thresholds, and number of iterations to be performed. Furthermore, main tie point cloud quality measures can be directly assessed. We will demonstrate that the time required to clean tie point clouds (using a computer equipped with a 3.60 GHz processor, 64 GB Ram, and NVIDIA Quadro M4000) can be significantly reduced, such that cleaning of a (unprocessed) ~8 million tie point cloud is achieved unattended in about 30 minutes (default cleaning threshold values used), with ~7 million tie points being automatically removed while significantly increasing point cloud quality measures.

This system is used as an illustrative example to show the role of singular extremals in the control of quantum systems. We analyze a simple case where the control law is explicitly determined. We experimentally implement the optimal control using techniques of nuclear magnetic resonance. To our knowledge, this is the first experimental demonstration of singular extremals in quantum systems with bounded control amplitudes.

title: Detailed multi-stratigraphic correlation of the continental latest Permian to Middle Triassic across Central Europe

Year: 2023

description:
In Central Europe, the about 1 km thick Buntsandstein was deposited in the large intracratonic Central European Basin (CEB). The Buntsandstein sedimentary succession displays a striking cyclicity of varying magnitude. The most obvious cycle is the 10 to 20 m thick small-scale cycle (wet-dry cycle) that is ascribed to changes in lake level (base-level) and assumed to be controlled by astronomical forcing of climate.

Combined with wireline logs, these cycles can be mapped over large parts of the Central European Basin providing a high-resolution cyclostratigraphic framework. Hence, the cycles represent basin-wide events. The isochronous character of this framework has been proven by magneto- and biostratigraphic means. The detailed magnetostratigraphy spans the upper Zechstein to lowermost Muschelkalk. Compared with available radioisotopic ages for the base and top of the marine Early Triassic, a Buntsandstein duration of about 6 Ma is derived.

Within the more central part of the CEB, the synchronous character of the cyclostratigraphic framework has been proven by magnetostratigraphic and biostratigraphic means. Based on an integrated comparison, radioisotopic ages obtained from Tethyan sections, have been referred successfully to the Buntsandstein cyclostratigraphy, substantiating the hypothesis that the pronounced small-scale cycles correspond to solar-induced ~100 ka eccentricity cycles. Hence, the duration of the Buntsandstein has been calculated to span some 6 Ma. The Buntsandstein cyclostratigraphy offers good potential to constructing a reliable astronomically calibrated Early Triassic geomagnetic polarity timescale.

description: It is shown that any finite-dimensional homomorphic image of an inverse limit of nilpotent not-necessarily-associative algebras over a field is nilpotent. More generally, this is true of algebras over a general commutative ring k, with "finite-dimensional" replaced by "of finite length as a k-module". These results are obtained by considering the multiplication algebra M(A) of an algebra A (the associative algebra of k-linear maps A -> A generated by left and right multiplications by elements of A), and its behavior with respect to nilpotence, inverse limits, and homomorphic images. As a corollary, it is shown that a finite-dimensional homomorphic image of an inverse limit of finite-dimensional solvable Lie algebras over a field of characteristic 0 is solvable. Examples are given showing that infinite-dimensional homomorphic images of inverse limits of nilpotent algebras can have properties far from those of nilpotent algebras; in particular, properties that imply that they are not residually nilpotent. Several open questions and directions for further investigation are noted.

description: This thesis presents data collected from the Bennett-Gherga-Retchnizer dataset of elliptic curves of prime conductor over the rationals. For these curves, we analyze the behaviors of the invariants which appear in the Birch and Swinnerton-Dyer conjecture - we present comparisons to the literature and point out differences and similarities between the families of elliptic curves of prime and composite conductors. Moreover, we present heuristic and computational evidence towards biases in the ranks, conductors and coefficients of elliptic curves within the latter family.

description: Adolescents who experience bullying victimization – and are thus targets of repeated, intentional acts of aggression by a more powerful peer – are at increased risk for potentially long-lasting psychosocial and mental health problems (Moore et al., 2017). One way to better understand the detrimental impact of bullying victimization may be to closely examine how a history of bullying victimization can affect daily-life experiences. This includes examining the association between bullying victimization and an individual’s basic psychological needs (i.e., relatedness, autonomy, competence), subjective and physiological stress, and the daily within-person dynamics of these factors.

Separate lines of prior research indicate that individuals who are victimized experience frustration of their basic psychological needs and report higher levels of stress in daily life (Cristóbal-Narváez et al., 2016; Santurio et al., 2020; Young-Jones et al., 2015). These outcomes may also be interrelated. For example, needs frustration has been shown to be related to indices of physiological stress, including increased levels of cortisol (Bartholomew et al., 2011; Quested et al., 2011). Additionally, subjective stress has been associated with increased momentary cortisol (Stoffel et al., 2021). Therefore, bullying victimization may also modulate the daily within-person associations between needs frustration and subjective and physiological indices of stress.

The present study will address the following research questions:
1) To what extent is a history of bullying victimization associated with daily experiences of needs frustration and subjective stress at the between-person level?
2) To what extent does a history of bullying victimization modulate the within-person associations between event-related needs frustration and subjective stress, needs frustration and diurnal cortisol levels, and subjective stress and cortisol levels?
3) Similarly, to what extent does a history of bullying victimization modulate the within-person association between day-level needs frustration and diurnal cortisol levels, as well as day-level subjective stress and diurnal cortisol levels?

To address these research questions, we will use data from a broader longitudinal project (Outside-In), which includes an experience sampling methodology (ESM) and repeated cortisol assessments over multiple days in an adolescent sample.

description: In this paper, we report a new scheme to amplify a microwave signal carried on a laser light at $λ$=852nm. The amplification is done via a semiconductor tapered amplifier and this scheme is used to drive stimulated Raman transitions in an atom interferometer. Sideband generation in the amplifier, due to self-phase and amplitude modulation, is investigated and characterized. We also demonstrate that the amplifier does not induce any significant phase-noise on the beating signal. Finally, the degradation of the performances of the interferometer due to the amplification process is shown to be negligible.

description:
Nano-magnetite is a potential archive for biosignatures of iron-cycling microorganisms in hydrothermal systems, which are widely considered to be among the most ancient microbial habitats on Earth. Sulfidic diagenesis driven by hydrothermal fluids and microbial sulfur cycling potentially causes the rapid transformation of magnetite to iron sulfide minerals. Thus, identifying nano-magnetite and its transformation products in hydrothermal sulfide deposits is crucial for reconstructing iron- and sulfur-cycling microbial life in deep time. However, the identity and characteristics of iron sulfide minerals resulting from nano-magnetite sulfidation at hydrothermal conditions have previously not been constrained. Here we present experimental data on sulfidation reactions of synthetic and biogenic nano-magnetite at physical and chemical conditions relevant to microbial habitats in hydrothermal systems on early Earth (<121°C, anoxic, sulfidic). We characterize the resulting precipitates with analytical imaging techniques, mineralogical methods, and geochemical approaches (e.g., SEM-EDS, µXRD, Raman spectroscopy, sequential Fe extraction). Our results demonstrate a potential taphonomic bias against nano-magnetite in sulfidic hydrothermal habitats and suggest that biosignature records of iron- and sulfur-cycling microorganisms in ancient hydrothermal sulfides are affected by diagenetic fluid-mineral interactions.

description:
The formation of a segregated metallic core is viewed as an inevitable consequence of the growth of larger protoplanets. However, the effect of this process on the distribution of siderophile elements is hugely variable depending on the physiochemical nature of the protoplanet and the pressure and temperature at which metal-silicate equilibration occurs. On Earth, study of this process can be complicated by the overprinting effect of late accretion, which delivered additional siderophile element mass to the Earth. Along with Precambrian-aged mantle-derived rocks, ocean island basalts (OIB) are now recognized as an important source of information about the early siderophile evolution of the deep Earth. We demonstrate that the combined W isotopic and highly siderophile element (HSE) characteristics of major global hotspots (Hawaiʻi, Iceland, Réunion) preserve geochemical signatures secondary to Hadean metal-silicate equilibration that have not been overprinted by late accretion. Further, some OIB preserve Ru/Ir ratios that are higher than expected, either for chondritic material delivered by late accretion or for the more highly processed primitive mantle. These elevated Ru/Ir signatures are not always easily explained by partial melting and/or magma differentiation processes and must in part reflect elevated Ru/Ir ratios in the deep mantle sources of OIB. Ruthenium has previously been investigated for its unique behavior among HSE during metal-silicate equilibration and heterogeneous, pre-late accretion Ru isotopic signatures have been recognized in some Archean-aged mantle-derived rocks. This implies that OIB may be an untapped source of information about the state of Earth’s interior during and after core formation.

description:
The Late Cretaceous collision of the Adriatic microplate with Eurasia resulted in an overall SW-vergent and in-sequence structural architecture of the Dinarides. In the Paleogene the deformation propagated from the Internal towards the External Dinarides, associated with ca. 130 km of crustal shortening. Fault kinematic data and balanced cross-sections across the External Dinarides suggest contrasting styles along-strike the orogen, separated by a ca. 250 km long dextral transpressive fault. This fault delimits the southern, SW-vergent nappe stack segment from a northern, NE-vergent backthrust-dominated Velebit segment. Based on the distribution of the flexural foreland basin sediments, it is known that these two domains deformed contemporaneously, which marked the end of the Paleogene Dinaric orogeny.

Within these Eo- to early Oligocene syntectonic and older Mesozoic carbonate platform rocks horizontal marine terraces are preserved at elevations of up to 600 m. We extracted terrace surfaces along the entire Adriatic coast from DEMs. All these flat surfaces are degradational, not related to bedding or faults, and they are located on the western side of the main drainage divide facing the Adriatic Sea. Their spatial correlation is in agreement with the position of a reported negative P-wave tomography anomaly, which in turn correlates with the thinned part of the Adriatic lithosphere. Our findings suggest an orogen-wide surface uplift affecting the Dinarides in the Neogene due to mantle delamination.

Our overarching results show that the Paleogene Dinaric orogeny was related to high crustal shorten- and thickening, whereas the Neogene was related mainly to surface uplift.

description: Autobiographical memory distortions are a key feature of posttraumatic stress disorder (PTSD). In this proof-of-concept randomized controlled trial (N = 43), we evaluated an autobiographical memory flexibility intervention, MemFlex. We aimed to determine whether the mechanism-focused intervention, which aims to improve autobiographical memory processes, may also affect other cognitive predictors of PTSD and potentially reduce PTSD symptoms in Iranian trauma survivors diagnosed with PTSD. Results indicated significant, moderate to large between-groups effect sizes in favor of MemFlex, relative to wait-list control, for the targeted cognitive mechanism of autobiographical memory flexibility and PTSD symptoms. A large, significant effect was also observed on maladaptive posttraumatic cognitions—a strong predictor of PTSD prognosis, which is a key target of high-intensity cognitive therapies for PTSD. Findings support future completion of a scaled-up trial to evaluate treatment efficacy of MemFlex for PTSD to determine whether MemFlex may offer a culturally adaptive, low-cost, low-intensity intervention able to improve cognitive mechanisms of PTSD.

It is based on parametric down-conversion with N pairs of symmetrically-tilted plane waves serving as a pump. The characteristics of this spatial entanglement are investigated in the cases of zero as well as nonzero phase mismatch. Furthermore, the phenomenon of entanglement localization in just two spatial modes is studied in detail and results in an enhancement of the entanglement by a factor square root of N.

description:
Understanding ancient climate changes is hampered by the inability to disentangle trends in continental ice volume from records of relative sea-level change. As a unique coastal deposit in tropical and subtropical regions, beachrock has been proved to be reliable for constraining the glacial meltwater signal and, thus, the total volume of land-based ice in the Quaternary. However, beachrock is rarely recognized in the fossil record due to (a) the 2-dimensional distribution of beach deposits, as opposed, for example, to extended platform sediments, and (b) the fact that specific environmental conditions are required in order to lithify sediments directly at the beach.

By combing the stratigraphic architecture with petrography of characteristic cements, we show the first Ordovician beachrock from the Tarim Block, northwestern China. According to biostratigraphic data, a middle Katian (Upper Ordovician) palaeokarst surface is capped by a carbonate conglomerate beachrock, indicating a significant late Katian relative sea-level rise.

These beachrocks can be correlated with the onlap on the widespread subaerial exposure surfaces during deglaciation and post-glacial sea level rise. They formed in northwestern Tarim Basin after a pronounced stratigraphical gap reflecting the expression of a Katian glacial. We suggest that the beachrock ‘fingerprinted’ a strong melt-water pulse in high latitudes after this short-lived glaciation, which until now did not receive much attention in the scientific literature.

Empirical trophic models (Vollenweider-type) are one of the basic "tools of the trade" in management of natural and artificial lakes. They are not applicable to open-cast mining lakes (PML) because they underestimate their resilience to phosphorus (P) inputs. The high iron availability causes an efficient binding for phosphorus (P) in water and sediment of PML. The main objective was use hydrogeochemical modelling to assess the risks of eutrophication in the following way:

i) to develop conceptual (empirical) models (Vollenweider type) that can be used to more accurately estimate tolerable P loading to PMLs

ii) to represent the transition range from conditions with Fe excess to natural conditions in a model structure

iii) to identify specific indicators and tipping points for different P retention.

We analysed hydrological data, loads, and sediment properties to derive a closed P balance for 29 neutral mining lakes. The latter cover a range of water retention times and external P inputs. We distinguished three phases of PML development or maturation and the relevance of P-binding processes or binding forms. The Fe:P ratio in sediment was found to be the most important predictor of P retention. By integrating this ratio into conceptual models it is now possible to predict in-lake P-concentration from P inputs for PMLs and even for lakes with decreasing Fe import at the transition to “natural lake” conditions. We conclude that processes such as Fe~P adsorption and vivianite formation under anoxic conditions most likely ensure high P retention in the long term.

description:
The University Campus Charlottenburg/Berlin will be used as an example to show how geothermal energy can make a decisive contribution to a climate-neutral university campus. In combination with heat pumps, geothermal energy offers the possibility of a secure heat supply for the campus, which is in the process of transformation. The investigation addresses the geological horizons Muschelkalk and Buntsandstein at depths of 900 - 1250 m. Temperatures of 45 - 63°C and an extraction capacity of 1.2 to 4.7 MW are expected. Depending on the outside temperatures, direct use for heat supply can take place. The ongoing renovation process on campus significantly increases the direct use potential of geothermal energy. In the retrofitted state, the maximum supply temperature drops to 60°C with an outside temperature of -10°C.  This demonstrates that the geothermal use of the underground can provide a reliable heat source for the transformation process on campus or in city quarters in general. An essential aspect of this utilization is the redesign of the heating network to allow a differentiated supply of buildings with different temperature levels. The example of the location's south campus shows that the use of geothermal energy enables a CO2 savings potential of up to 64%. In addition, the use of geothermal energy for cooling supply via ad- and absorption chillers is investigated. This approach opens up new perspectives for the holistic use of geothermal energy and helps to increase efficiency and conserve resources in campus operations.

description:
The energy concept for the VW library in Berlin, which was built in 2004, centers on a ground foundation absorber (GFA) that uses concrete core temperature control to freely cool the building in the summer and cover the building's base heating load in the winter via a heat pump. Due to unexpectedly high subsurface temperatures beneath the building, as well as difficulties in controlling the concrete core temperature control system, the GFA has been largely decommissioned in recent years. The goal of this research is to work with building engineers and engineering geologists to determine the cause of the elevated temperatures and to transition the GFA to optimized seasonal operation. To this end, detailed thermal models were created for the building and the subsurface, validated with measured data, and coupling approaches between the models were investigated. This should ensure a better evaluation of the interaction between the subsurface and the building during operation. Model-based parameter studies will then be used to determine an optimally adjusted operation of the GFA. In addition, the temperature development of the subsurface of the study area will be investigated to ensure sustainable operation. Optimized reactivation of the GFA shows significant ecological and economic potential with annual savings of 15% of the building's CO2 emissions and €23,000 in energy costs compared to the current building operation. The developed adjustments to the operating and control parameters will be tested and monitored in the building during the coming heating periods.
Environmental impacts on hybridization outcomes

description: Hybridization is the process of interbreeding between distinct genomic lineages. Environmental disturbances have been associated with increased hybridization between previously non-interbreeding lineages, suggesting that the production and survival of hybrids is influenced by the ecological conditions in which they occur. However, our understanding of hybridization, hybrid evolution, and the impact of natural selection on hybrid populations is limited compared to that of parent species. To address these gaps, my dissertation focused on investigating the effects of environmental changes on hybrid production and fitness, and the mechanisms driving the evolution of hybrid populations. Threespine stickleback fish served as a model for my thesis as they have diverged at least five times to form limnetic and benthic species capable of producing viable hybrid offspring. These species exhibit strong reproductive isolation and low hybrid fitness under natural conditions, but collapse into a hybrid swarm has been observed once in nature. In Chapter 2, I conducted experiments manipulating pond conditions to examine if eutrophication would disrupt reproductive isolation and influence hybrid survival as a consequence of reduced visibility and an altered ecological fitness landscape. Although our treatment did not appear to affect hybrid production or survival, we nonetheless observed an increase in hybrids independent of the treatment, highlighting the fragility of reproductive isolation in ecologically specialized species. In Chapter 3, inspired by the collapse of stickleback species in Enos Lake, I examined the fitness of F1 hybrids in the presence of crayfish. We observed a slight, but non-significant improvement in relative hybrid fitness as a consequence of changes in parent fitness. Chapter 4 focused on the evolution of three wild stickleback hybrid populations with varying proportions of parental ancestry inhabiting similar environments. We found parallel evolution in both genotypic and phenotypic traits across the hybrid populations, regardless of their ancestry, providing evidence for the significant role of ecological selection in shaping these populations. In summary, my dissertation sheds light on the crucial role of ecological context in mediating the outcomes of hybridization and emphasizes the need to improve our understanding of this process and its implications on the evolution and persistence of hybrid populations.

description:
Ocean sediments are considered to contain microbial biomass that equals the stock of organic matter on all the continents combined. Knowledge on the spatiotemporal distribution and abundance of microbial life in marine subsurface sediments, however, is still sparse. A region particularly understudied in this respect is the Antarctic continental margin, in which the deep biosphere is largely terra incognita. A 794 m-long sediment sequence (Site U1532), recovered during IODP Expedition 379: “Amundsen Sea West Antarctic Ice Sheet History” provides the unique opportunity to study the composition and abundance of the deep biosphere in polar regions of the Southern Hemisphere. Porewater profiles of sulfate and methane concentrations indicate that the sulfate-methane transition zone (SMTZ) is located at a depth of ~660 mbsf, making it one of the deepest SMTZ ever encountered. Stable carbon isotope measurements attest to the biological origin of the methane and provide direct evidence for an active deep-dwelling microbial community. Cell abundances decline with depth by three orders of magnitudes but increase again within the SMTZ. Complementary biomarker analysis indicates that this change in cell abundances is associated with a shift in the microbial community to predominantly methanogens throughout the SMTZ. Our data thus provides first insights into the microbial diversity and abundance of the deep biosphere in the yet largely unstudied marine subsurface sediments surrounding Antarctica. Combining our results with previous data of cell abundances in marine sediments suggests that current projections of microbial biomass appears to be overestimated and need to be downsized.
title: Key role of Fe-carbonates in natural H2 production? Evidence from the spatial link between barren ground depressions, gold deposit and H2 emissions

description:
Even if measurements of high H2 concentrations in continental rocks have significantly increased in the last decade, the origin of H2 remains enigmatic in this context. Here we show that the localities in continental rocks where H2-rich gases have been reported are mainly located near orogenic gold deposits. Two types of geomorphological features were identified near orogenic gold deposits on satellite images. They consist in both barren ground depressions and high densities of self-organized, small (< 20 m in diameter) circular- and comet-shaped white spots in 32 and 7 localities, respectively. Fe-carbonates commonly occur near gold deposits since gold is transported in CO2-rich fluids. Thermodynamic modelling reveal here that they can further dissolve in the presence of aqueous fluid to produce magnetite and up to ~ 1 mole of H2 per kg of rock. This reaction leads to a volume decrease of ~ 50 %. Based on these findings, we propose that Fe-carbonate dissolution could be the primary source of H2 in orogenic gold deposit areas, and involved in the formation of the geomorphological structures reported here. The association between H2-rich gas and ground depressions was also observed near other formations containing Fe-carbonates such as iron formations and carbonatites. This suggests that H2 production through Fe-carbonate dissolution is not restricted to gold deposits. The global H2 production in crustal rocks associated with Fe-carbonate alteration is estimated to 3 x 105 mol/yr.
