description: Multichannel seismic data acquired in the Lesser Antilles in the western tropical North Atlantic indicate that the seismic reflection method has imaged an oceanic thermohaline staircase. Synthetic acoustic modeling using measured density and sound speed profiles corroborates inferences from the seismic data. In a small portion of the seismic image, laterally coherent, uniform layers are present at depths ranging from 550-700m and have a separation of ~20 m, with thicknesses increasing with depth. The reflection coefficient, a measure of the acoustic impedance contrasts across these reflective interfaces, is one order of magnitude greater than background noise. Hydrography sampled in previous surveys suggests that the layers are a permanent feature of the region. Spectral analysis of layer horizons in the thermohaline staircase indicates that internal wave activity is anomalously low, suggesting weak internal wave-induced turbulence. Results from two independent measurements, the application of a finescale parameterization to observed high-resolution velocity profiles and direct measurements of turbulent dissipation rate, confirm these low levels of turbulence. The lack of internal wave-induced turbulence may allow for the maintenance of the staircase or may be due to suppression by the double-diffusive convection within the staircase. Our observations show the potential for seismic oceanography to contribute to an improved understanding of occurrence rates and the geographical distribution of thermohaline staircases, and should thereby improve estimates of vertical mixing rates ascribable to salt fingering in the global ocean.

description: In a many-to-many matching model in which agents' preferences satisfy substitutability and the law of aggregate demand, we present an algorithm to compute the full set of stable matchings. This algorithm relies on the idea of "cycles in preferences" and generalizes the algorithm presented in Roth and Sotomayor (1990) for the one-to-one model.

description: The $k$-associahedron $Ass_k(n)$ is the simplicial complex of $(k+1)$-crossing-free subgraphs of the complete graph with vertices on a circle. Its facets are called $k$-triangulations.
 We explore the connection of $Ass_k(n)$ with the Pfaffian variety $Pf_k(n)\subset {\mathbb K}^{\binom{[n]}2}$ of antisymmetric matrices of rank $\le 2k$.
 First, we characterize the Gröbner cone $Grob_k(n)\subset{\mathbb R}^{\binom{[n]}2}$ producing as initial ideal of $I(Pf_k(n))$ the Stanley-Reisner ideal of $Ass_k(n)$ (that is, the monomial ideal generated by $(k+1)$-crossings). This implies that $k$-triangulations are bases in the algebraic matroid of $Pf_k(n)$, a matroid closely related to low-rank completion of antisymmetric matrices.
 We then look at the tropicalization of $Pf_k(n)$ and show that $Ass_k(n)$ embeds naturally as the intersection of $\operatorname{trop}(Pf_k(n))$ and $Grob_k(n)$, and is contained in the totally positive part $\operatorname{trop}^+( Pf_k(n))$ of it.
 We show that for $k=1$ and for each triangulation $T$ of the $n$-gon, the projection of this embedding of $Ass_k(n)$ to the $n-3$ coordinates corresponding to diagonals in $T$ gives a complete polytopal fan, realizing the associahedron. This fan is linearly isomorphic to the $\mathbf g$-vector fan of the cluster algebra of type $A$, shown to be polytopal by Hohlweg, Pilaud and Stella in (2018).

description: En el transcurso del siglo XX, la lobotomía se erigió como una controvertida práctica psiquiátrica que buscaba aliviar los trastornos mentales a través de la intervención cerebral. Aunque la técnica se desarrolló inicialmente esperando tratar diversas enfermedades mentales, su aplicación generó discusiones éticas y morales a nivel mundial. En el contexto colombiano, la adopción de la lobotomía como método terapéutico plantea interrogantes particulares sobre la historia de la psiquiatría en el país. Este trabajo se propone explorar y analizar el fenómeno de la lobotomía en Cundinamarca, examinando sus raíces, su evolución a lo largo del tiempo y las posibles implicaciones médicas, sociales y éticas que acompañaron su implementación en la práctica clínica colombiana además de su difusión a lo largo del departamento de Cundinamarca. En este contexto, se revela una intersección fascinante entre la ciencia médica, la cultura y las políticas de salud mental en Colombia, ofreciendo una visión más completa de la compleja relación entre la medicina y la sociedad en el siglo pasado.

description: No abstracts are to be cited without prior reference to the author. Marine fishes have hitherto been characterised by lower genetic differentiation when compared with anadromous and freshwater species (Ward et al 1994), which has been related to a presumed lack of isolating barriers, large population sizes, and high mobility (Smith 1994, Carvalho & Hauser 1998). However, it has been suggested that some studies that found a lack of genetic differentiation may have done so because of inappropriate sampling (e.g. insufficient sample sizes, sampling of non-spawning stocks) or use of insensitive molecular markers (O’Connell & Wright 1997, Carvalho & Hauser 1998, Waples 1998).

description: No abstracts are to be cited without prior reference to the author.1245 individuals of cod (Gadus morhua L.) caught in 12 spawning seasons during 1985-1999 from a well defined spawning area in the Trondheimsfjord (Norway) were genotyped for the polymorphic cDNA RFLP marker SypI (synaptophysin) and (for the same individuals plus 1080 additional specimens) for the polymorphic haemoglobin locus HbI*. A highly significant temporal instability in SypI allele frequencies was observed, as well as highly significant differences in allele frequencies between males and females. The females showed a significant trend of heterozygote excess at SypI. SypI genotypic differences in body length and within spawning season gonadic development stage were also observed and a significant heterogeneity in allele frequencies between age groups. None of these effects were observed at HbI*. Genetic drift, immigration and mutation were rejected as sufficient explanatory factors for the observations made at the SypI locus. There were on the other hand strong indications that the SypI locus is strongly influenced by natural selection, involving overdominance in the females and directional selection in the males in the Trondheimsfjord cod stock.

title: a critical participatory action research study on the transformational potential of human rights education
titleType: Subtitle
Creators: name: Lough, Emma

description: This thesis examines the value of a Community Development approach to
 enhancing the transformative potential of community-based models of Human
 Rights Education (HRE). The UN’s definition of HRE builds on the idea of
 human rights as a set of accepted standards and the purpose of pedagogical
 spaces to build a culture in which they are normalised and respected. Yet
 since the recent proliferation of HRE, growing numbers of accounts take a
 critical perspective that confronts the conservatism and historicism of
 HRE in its traditional “declarationist” form (Keet, 2007, p. 7). This
 critical orientation calls for a pedagogical “renewal” to return HRE to
 its emancipatory purpose and positions Critical Human Rights Education
 (CHRE) as a route forward (Keet, 2012, p. 7).

 Yet given the relatively recent interest in this field, there is a
 comparative lack of practice-based studies that explore the critical
 position, and consequently the viability of CHRE as an alternative to the
 “declarationist” model. In this study, I use a Critical Participatory
 Action Research (CPAR) methodology to explore the ways in which an
 approach to HRE modelled on Margaret Ledwith’s (2020) framework for
 Community Development may enhance its potential to create spaces for
 critical learning and transformative action. I do so by examining the way
 in which a UKbased Civil Society Organisation (CSO) piloted an HRE
 initiative with four community-activists over a six-month period. I
 suggest that, while there is need for more practice-based studies,
 Community Development is well positioned to advance CHRE through its
 direct engagement with issues around power and agency and argue for a
 closer alignment between the two fields with opportunities to strengthen
 both the theoretical and practical learnings between the two.

description: For general ferromagnetic Ising models whose coupling matrix has bounded spectral radius, we show that the log-Sobolev constant satisfies a simple bound expressed only in terms of the susceptibility of the model. This bound implies very generally that the log-Sobolev constant is uniform in the system size up to the critical point (including on lattices), without using any mixing conditions. Moreover, if the susceptibility satisfies the mean-field bound as the critical point is approached, our bound implies that the log-Sobolev constant depends polynomially on the distance to the critical point and on the volume. In particular, this applies to the Ising model on subsets of $\mathbb{Z}^d$ when $d>4$.
 The proof uses a general criterion for the log-Sobolev inequality in terms of the Polchinski (renormalisation group) equation, a recently proved remarkable correlation inequality for Ising models with general external fields, the Perron--Frobenius theorem, and the log-Sobolev inequality for product Bernoulli measures.

description: No abstracts are to be cited without prior reference to the author.Significant differences were found at the synaptophysin (Syp I) locus between two groups of Icelandic cod, Gadus morhua; Loftstaðahraun (spawning ground), Reykjanesgrunn and Eyrabakkabugur (feeding grounds) on one hand and Kantur (spawning ground) and Austfjarðadjúp (feeding ground) on the other hand. There was also a considerable genetic heterogeneity within the former group. The results indicate that the cod in south and south-east Icelandic waters do not belong to one panmictic population.

description: In this work, we demonstrate (1) a facile method to prepare Mn doped CdSe quantum dots (QDs) on Zn2SnO4 photoanodes by pulsed laser deposition and (2) improved device performance of quantum dot sensitized solar cells of the Mn doped QDs (CdSe:Mn) compared to the undoped QDs (CdSe). The band diagram of photoanode Zn2SnO4 and sensitizer CdSe:Mn QD is proposed based on the incident-photon-to-electron conversion efficiency (IPCE) data. Mn-modified band structure leads to absorption at longer wavelengths than the undoped CdSe QDs, which is due to the exchange splitting of the CdSe:Mn conduction band by the Mn dopant. Three-fold increase in the IPCE efficiency has also been observed for the Mn doped samples.

description: Light absorbing carbonaceous aerosols produced from combustion span over a range of physicochemical properties. Soot is the most recognized species in this category and its formation process involves gradual maturation from amorphous young soot with a high hydrogen-to-carbon-ratio toward mature soot aggregates. In this work, the optical response of a single particle soot photometer (SP2) to electrical mobility size selected soot of different maturity produced by a mini-CAST soot generator is investigated. The results show that for soot of a specific mobility diameter, the laser-induced incandescence (LII) signal appears earlier and with a higher LII peak height for increasing soot maturity. The experimental observations are supported by simulations using a numerical model for the LII process. Furthermore, the effect of systematically varying the SP2 laser power on the detection of soot of different maturity using LII is explored. This work can be seen as a step toward the aim of using the SP2 instrument to identify soot particles of different maturity in the atmosphere.

description: The continuum $φ^4_2$ and $φ^4_3$ measures are shown to satisfy a log-Sobolev inequality uniformly in the lattice regularisation under the optimal assumption that their susceptibility is bounded. In particular, this applies to all coupling constants in any finite volume, and uniformly in the volume in the entire high temperature phases of the $φ^4_2$ and $φ^4_3$ models.
 The proof uses a general criterion for the log-Sobolev inequality in terms of the Polchinski (renormalisation group) equation, a recently proved remarkable correlation inequality for Ising models with general external fields, the Perron--Frobenius theorem, and bounds on the susceptibilities of the $φ^4_2$ and $φ^4_3$ measures obtained using skeleton inequalities.

description: We study the magneto-optical properties of Fe-Co-Al ordered alloys in the terahertz range of frequencies. Using the standard Kubo-based approach to compute intrinsic part of the $σ_{xy}(ω)$ we find a strong dependence of $σ_{xy}$ on $ω$ in the terahertz range. For example, we find that below 10~THz Co$_3$Al has nearly constant $σ_{xy}$ and that above 10~THz it is reduced by about 50 times. Furthermore, we find a strong dependence of $σ_{xy}$ on the chemical composition. For example, we find that the addition of Al to Fe changes the sign of $σ_{xy}$, while the addition of Co to Fe leads to a nonmonotonic dependence of $σ_{xy}$ on Co concentration.

description: No abstracts are to be cited without prior reference to the author.The spawning stock of North Sea cod is at a historic low level and immediate management measures are needed to improve this situation. As a first step, the European Commission in 2001 closed a large area in the North Sea between February 15 and April 30 to all cod related fishing fleets in order to protect the spawning population. The closed area comprised important fishing grounds of the beam trawl fleet fishing for flatfish. In this paper the response of the Dutch fleet (components 225-300hp and >300hp) is analysed using data from EU-logbooks and from position recordings from the Vessel Monitoring System. No change was observed in the fleet of small beam trawlers. The fleet of large vessels displaced its activity to fishing grounds in the North Sea outside the closed areas, and to fishing grounds outside the North Sea. In the North Sea, beam trawling concentrated along the borders of closed areas and the Plaice Box. In the first week after the closure the number of trips in the open area doubled. Coinciding with this increase, the catch rate, expressed as revenue per hp-day, decreased. After the area was re-opened, the catch rate was exceptionally high but decreased to the normal level in the 2nd - 3rd week. The change in catch rate in relation to the change in fishing effort indicated that competitive interactions (in particular interference interactions) occurred among vessels. The implication of the observed fleet response is discussed against the background of the objective of the management measure to protect cod and the broader objective of the Common Fisheries Policy of ecosystem management. It is concluded that it is unlikely that cod has benefited from the area closure. Furthermore, the closure may have had a negative impact on the rate of discarding of demersal species and a negative impact on vulnerable components of the ecosystem (e.g. skates, long lived benthic species) due to an increase in trawling activities in certain areas.

description: To study bioaerosols under controlled conditions, aerosol chambers equipped with aerosol generators have been used for a long time. The method used for generation can change the constitutionand properties of the bioaerosol produced, including the viability of fungal spores, bacteria or airborne viruses. The properties of a bioaerosol in turn influence the results of detection and enumeration methods downstream. To evaluate and compare bioaerosol generators, previous methods provided either real-time data without particle characterization, relied on labor-intensive microscopy or used culturing, which has high variability. In our study, we used the novel instrument SwisensPoleno Jupiter, providing real-time enumeration and subsequent bioaerosols characterization through holographic image analysis. With this tool, we investigated the characteristics of bioaerosols produced by four different aerosol generators using fungal spores from Aspergillus brasiliensis, Cladosporium cladosporioides and Trichoderma longibrachiatum in controlled chamber environments. The rotating brush generator (RBG) produce small, round particles for A. brasiliensis, between 5 and 15 µm, while the fungal aerosol generator (FAG) released small particles for C. cladosporioides and T. longibrachiatum. Conversely, the SwisensAtomizer (SWA) produced larger non-spheric particles, likely spore aggregates, and the liquid sparging aerosolizer (LSA), exhibited a high portion of datapoints with empty images, supposedly water droplets. All generators showed a wide range of particle sizes. Holographic image analysis revealed that the choice of bioaerosol generator had a significant influence on the constitutionof produced aerosols, in terms of proportions of single spores, chains and agglomerates, emphasizing the importance to select the bioaerosol generator depending on the desired aerosol.

description: The chemical constituents of Polygonum perfoliatum L. were qualitatively analysed by UPLC-MS/MS, and the biological activity of its ethanol extract was determined. 94 chemical constituents were identified, including 32 flavonoids, 5 phenylpropanoids, 6 phenols, 6 alkaloids, 13 fatty acyls, 6 organic acids, 12 amino acids and polypeptides, and 14 other classes. The biological activity showed that the antioxidant capacity of the extract increased with the increase in concentration. The inhibitory activity against α-glucosidase IC50 = 1.643 μg/mL; at the concentration of 1 mg/mL, the inhibition rate of MV4-11 and SW480 cells reached more than 90%, and the IC50values were 237.5 μg/mL and 157.6 μg/mL, respectively. The study laid a sure foundation for elucidating the chemical composition and pharmacodynamic basis of Polygonum perfoliatum L.

description: No abstracts are to be cited without prior reference to the author.Traditionally monitoring and assessment of fish stocks are done on a single stock basis, without consideration of wider social and economic issues. The Limfjorden case suggests that this traditional fisheries management viewpoint is too narrow. Effects on other elements of the ecosystems influence stakeholders’ perceptions of sustainable use, and these stakeholders influence management of the fisheries. The characteristics of the blue mussel fishery are described and we discuss which of these characteristics are determinants for successful management. The characteristics include the social and political setting of the fishery. It is suggested that the socio-economic conditions are key determinants for exploitation of the resource. Furthermore, the fishery, being coastal, has direct consequences for tourism and other recreational uses of the fjord and the activity is directly visible to a wide group of non-fishery stakeholders. The ICES Fishery System Working Group has expanded the assessment model used by the earlier Long-term management WG to include four elements 1) Fishery, 2) Monitoring and Data analysis, 3) Management decisions and 4) Implementation of management decisions. However, this model is found to be too restrictive for a full analysis of the blue mussel fishery system in Limfjorden. This paper discusses possible extensions of the model to take into account all stakeholders and their influence on management decisions. It is concluded that these groups have a major influence on management decisions and also, at least partly, determine implementation of management decisions.Co-management is often considered as fundamental for successful fisheries management within sustainability criteria. This thesis is discussed based on a case study of the fishery for blue mussels in Limfjorden, Denmark, a fishery generally accepted to be an example of sustainable exploitation of a resource, and is managed using a co-management scheme. The paper concludes with a short discussion of whether the experiences from the blue mussel fishery are relevant for large scale industrialised fisheries.

description: Spatio-temporal particulate matter (PM) measurements are critical to understanding emission profiles to develop effective mitigation strategies. However, high-resolution spatio-temporal measurements using research-grade instruments are cost-prohibitive, making low-cost sensors (LCS) a promising alternative. LCS measures particle light scattering intensity (Isc) and converts it to mass and number concentrations. Such measurements are influenced by particles’ physico-optical properties, which make LCS appropriate for measuring PM with similar properties to those used for calibration. This work evaluates the performance of an LCS (PurpleAir) against reference instruments (SMPS + APS) during cooking experiments performed in a test house where PM0.3/PM10 as high as 90% was observed. LCS demonstrated better correlations (R2) for PM1 (0.98–1), PM2.5 (0.96–1), and PM10 (0.88–1) compared to coarser size bins, i.e., PM1–2.5 (0.04–0.99) and PM2.5–10 (0.02–0.93). Measurements from different cooking activities show different linear fits. Isc calculated using size-resolved measurements of reference instruments also had different linear fits with corresponding mass concentrations, even after assuming the same refractive index for all cases, highlighting the dependence of size distribution on LCS measurements. On average, sub-300 nm particles accounted for up to 75 ± 18% of the total Isc. Such dominance of sub-300 nm particles leads to size misclassification by LCS, whose algorithm assumes the inability to measure sub-300 nm particles. Moreover, the Isc calculated using the size distribution reported by LCS is considerably lower than that of reference instruments. This mismatch can be attributed to truncated angle error and positioning of particles in the sensing zone relative to the photodiode. Copyright © 2024 American Association for Aerosol Research

description: Tertiary education plays a very important role in the life of a student to become a learned man and to get a good job in future to have a secure life. But student absenteeism causes in a very significant way, the low quality of the students and ultimately poor passing rate in the examination. To find out the causes of student absenteeism at the tertiary level. Sirajganj Government College was selected for collecting data on student absenteeism in tertiary education. Data were collected both from primary and secondary sources. Four categories of respondents: Principals, Teachers, Students and Guardians were sampled during the study period. The study showed that absenteeism occurred due to poverty, distance from home to college, teachers' sympathy towards the students in all their examinations, bad road conditions, lack of accommodation, lack of security for female students, no support from in-laws house, physical illness, unattractive class teaching, involvement with politics, lack of co-curricular activities, dependence much on hand notes, guide books, and private tuition. Several measures such as regular counselling of students, the exercise of regular co-curricular activities, regular rollcall, and imposition of rules and regulations of National University can easily stop student absenteeism in tertiary education in Bangladesh.

description: No abstracts are to be cited without prior reference to the author.The purpose of this study was to determine population structure of Atlantic cod (Gadus morhua) off Newfoundland and Labrador, with emphasis on the relationship between inshore and offshore spawning groups. Variation at seven microsatellite loci (Gmo3, Gmo8, Gmo19, Gmo34, Gmo35, Gmo36, and Gmo37) and SypI was surveyed in approximately 5,230 mature cod from 19 locations sampled mostly during the spawning period. FST estimates by locus were: Gmo3 0.0068, Gmo8 0.0047, Gmo19 0.0027, Gmo34 0.0162, Gmo35 0.0028, Gmo36 0.0069, Gmo37 0.0038, and SypI 0.0374, with the mean over all loci of 0.0080. Overall, the cod populations surveyed tended to conform to an isolation by distance structure, with cod from more distant locations tending to be more genetically distinct. Among offshore sites, the Flemish Cap population (NAFO Div. 3M) was the most distinctive, and among inshore sites the Gilbert Bay population in southern Labrador (2J) was the most distinctive. In NAFO Divs. 3KL, no significant genetic differentiation was observed among inshore northern cod sampled in four bays (Notre Dame, Bonavista, Trinity, and Conception) along the northeast coast of Newfoundland and the data do not support the hypothesis of separate “bay stocks”. Annual variation within sampling sites was as large, on average, as the differentiation among sampling sites. The inshore northern cod were distinct from the population in Gilbert Bay and distinct from most offshore northern cod populations. On average, regional differences in allele frequencies were seven times larger than annual variation. The offshore samples were more heterogeneous, and there may be at least three distinct offshore spawning populations of northern cod. In Subdiv. 3Ps, no consistent differentiation was observed among sampling sites, two in inshore bays (Placentia, Fortune), and two in the offshore (Burgeo Bank, Halibut Channel). The southern Grand Bank (Divs. 3NO) may have a separate spawning population from those in other offshore sites, but additional sampling is required to confirm population distinctiveness.

description: No abstracts are to be cited without prior reference to the author.Assessing the impact of management scenarii in multispecies multifleet fisheries requires spatially and seasonally explicit simulation tools. This paper presents a simulation tool that allows to evaluate the impact of management measures on the dynamics of a mixed fishery. The model aims at being as generic as possible in order to be applied to different types of fishery. Existing knowledge about each fishery may be stored in a database included in the software, and may be easily modified. This includes the parameters describing each population and each fishing activity. Furthermore, the software allows for flexibility in several model assumptions. Both management measures and behaviour of fishermen in reaction to these measures may be interactively designed through a Script language. The simulation tool thus enables one to compare the respective impacts of conventional management measures like catch and effort controls, and measures like Marine Protected Areas (MPA). It is illustrated by a comparison of the impact of TACs and MPAs upon a theoretical mixed fishery.

description: Combustion and air-pollution aerosol particles often contain a substantial mass fraction of carbon. In biomass or residual-fuel smoke, this carbon may span a continuum of molecular sizes and physical properties, from macromolecular black carbon (BC) and tarballs to smaller molecules of organic particulate matter (OM). The quantification of these materials presents a metrological challenge which rapid temperature programmed oxidation instruments (RTPOs) may address. RTPOs collect particles on filters, which are then rapidly heated (> 700 K/min) in ambient or synthetic air while CO2 in the emitted gases is quantified either with (e.g. the “FATCAT” instrument) or without (e.g., “TCA08”) first passing gases over an oxidation catalyst. Both RTPOs monitor CO2 concentrations in real time to provide thermograms; both report total carbon mass by reference to baseline-subtracted CO2 thermograms. In this study, we investigated the response of these instruments to a variety of laboratory samples. Integrated carbon mass from the FATCAT and TCA08 agreed with one another, and with reference measurements, for both mature, fully graphitized soot (OC/TC < 0.1) and young, partially formed soot (OC/TC = 0.6 after denuding at 350 °C). However, due to its lack of an oxidation catalyst, the TCA08 CO2 measurements were 10-fold lower than reference measurements for two model OM compounds (dioctyl sebacate and sucrose). Since a previous atmospheric study has observed consistency between a TCA08 and a reference instrument, our data imply a large difference in the evaporation kinetics of these surrogates and atmospheric OM, as expected for highly-viscous (glassy) atmospheric OM. Finally, we discuss the thermograms of nebulized BC surrogates (C60, graphene, graphite), which showed two peaks at lower and higher temperatures, even after denuding at 350 °C.

description: The new broadband seismic network in China will increase the number of stations from approximately 950 to 2000. The higher-resolution monitoring of the frequent smaller earthquakes expected inside Mainland China can be quantified via the completeness magnitude (Mc) metric. Using the Bayesian Magnitude of Completeness (BMC) method, we generate the spatial distribution of Mc predicted for the new network, based on the prior model calibrated on the current earthquake catalog (2012 to 2021) and network configuration. If 99% of Mainland China is at present covered down to Mc = 2.7, this threshold will soon fall to Mc = 2.0. This means approximately 3 times more earthquakes available per year. Based on the observation that seismic precursors are most likely to be observed at least at 3 units below the mainshock magnitude, the new seismic network shall achieve the goal of almost total coverage for optimal seismic-based earthquake prediction research.

description: We sought to characterize the ability of hummingbirds to fuel their energetically expensive hovering flight using dietary sugar by a combination of respirometry and stable carbon isotope techniques. Broadtailed hummingbirds (Selasphorus platycercus) were maintained on a diet containing beet sugar with an isotopic composition characteristic of C3 plants. Hummingbirds were fasted and then offered a solution containing cane sugar with an isotopic composition characteristic of C4 plants. By monitoring the rates of CO2 production and O-2 consumption, as well as the stable carbon isotope composition of expired CO2, we were able to estimate the relative contributions of carbohydrate and fat, as well as the absolute rate at which dietary sucrose was oxidized during hovering. The combination of respirometry and carbon isotope analysis revealed that hummingbirds initially oxidized endogenous fat following a fast and then progressively oxidized proportionately more carbohydrates. The contribution from dietary sources increased with each feeding bout, and by 20 min after the first meal, dietary sugar supported similar to 74% of hovering metabolism. The ability of hummingbirds to satisfy the energetic requirements of hovering flight mainly with recently ingested sugar is unique among vertebrates. Our finding provides an example of evolutionary convergence in physiological and biochemical traits among unrelated nectar-feeding animals.

description: No abstracts are to be cited without prior reference to the author.The two alleles found in cod at the scnDNA pantophysin locus (earlier termed synaptophysin) show distinct genetic divergence between cod caught offshore and inshore in northern Norway. Moreover, the two alleles display significant horizontal and vertical stratification in some fjords. In shallow water and in the innermost parts of fjords there is a total dominance of the A-allele, e.g. at a spawning ground in the inner Varangerfjord the A-allele accounted for 91 % of the gene pool. At intermediate depths and in the middle of fjords there is often a mixing zone, whereas in outer parts of fjords we often find a dominance of the B-allele. The change towards a dominance of the B-allele in the mouth of fjords is caused by the presence of NE arctic cod, which usually has frequencies of the B-allele greater than 90 %. NE arctic cod migrates down to near-coastal waters for spawning and feeding purposes. The profound divergence at this locus between NE arctic cod and the cod in fjords, indicate that they represent two genetically distinct groups. Differences in habitat preference and behaviour may be the main reason why the two groups can be found in the same fjord without exchanging genes to a large extent.
