re3data COREF Project

description: re3data is the global registry for research data repositories. As of October 2021, the service lists over 2700 digital repositories across all scientific disciplines and provides an extensive description of repositories based on a detailed metadata schema, the updated version of which was recently published. The service promotes open science practices and the visibility of science-driven open infrastructures. A variety of funders, publishers, and scientific organizations around the world refer to re3data within their guidelines and policies, recommending the service to researchers looking for appropriate repositories for storage and discovery of research data. The re3data web interface and API function as an important Science Gateway, allowing its end users and other services to access the largest index of research data repositories in the world. Since January 2020, the re3data COREF project receives funding from the German Research Foundation (DFG) to further develop and enhance the registry service. This presentation from the Gateways 2021 conference introduces the re3data service and gives an overview of the ongoing project work, including a short introduction to the recently published “Conceptual Model for User Stories” for re3data. The editorial process for the inclusion of repositories in re3data is explained and readers learn how to submit new entries and suggest changes. Readers also learn how to retrieve information and metadata from re3data. A recording of the session will be uploaded on Youtube.
Axion Stabilization in Type IIB Flux Compactifications

description: A scenario for stabilization of axionic moduli fields in the context of type IIB Calabi-Yau flux compactifications is discussed in detail. We consider the case of a Calabi-Yau orientifold with h^{1,1}_- \neq 0 which allows for the presence of B_2 and C_2-moduli. In an attempt to generalize the KKLT and the Large Volume Scenario, we show that these axions can also be stabilized - some already at tree level, and others when we include perturbative α'-corrections to the Kaehler potential K and nonperturbative D3-instanton contributions to the superpotential W. At last, we comment on the possible influence of worldsheet instantons on the process of moduli stabilization.

description: Blood rheology and microcirculation are strongly influenced by red blood cell (RBC) aggregation. The aggregability of RBCs can vary significantly due to factors such as their mechanical and membrane surface properties, which are affected by cell aging in vivo. In this study, we investigate RBC aggregability as a function of their density, a marker of cell age and mechanical properties, by separating RBCs from healthy donors into different density fractions using Percoll density gradient centrifugation. We examine the dissociation rates of aggregates in a controlled medium supplemented with Dextran, employing an extensional flow technique based on hyperbolic microfluidic constrictions and image analysis, assisted by a convolutional neural network (CNN). In contrast to other techniques, our microfluidic experimental approach highlights the behavior of RBC aggregates in dynamic flow conditions relevant to microcirculation. Our results demonstrate that aggregate dissociation is strongly correlated with cell density and that aggregates formed from the denser fractions of RBCs are significantly more robust than those from the average cell population. This study provides insight into the effect of RBC aging in vivo on their mechanical properties and aggregability, underscoring the importance of further exploration of RBC aggregation in the context of cellular senescence and its potential implications for hemodynamics. Additionally, it suggests that this technique can complement existing methods for improved evaluation of RBC aggregability in health and disease.

description: We derive the structural relations between the Mellin transforms of weighted Nielsen integrals emerging in the calculation of massless or massive single--scale quantities in QED and QCD, such as anomalous dimensions and Wilson coefficients, and other hard scattering cross sections depending on a single scale. The set of all multiple harmonic sums up to weight five cover the sums needed in the calculation of the 3--loop anomalous dimensions. The relations extend the set resulting from the quasi-shuffle product between harmonic sums studied earlier. Unlike the shuffle relations, they depend on the value of the quantities considered. Up to weight {\sf w = 5}, 242 nested harmonic sums contribute. In the present physical applications it is sufficient to consider the sub-set of harmonic sums not containing an index $i = -1$, which consists out of 69 sums. The algebraic relations reduce this set to 30 sums. Due to the structural relations a final reduction of the number of harmonic sums to {15} basic functions is obtained. These functions can be represented in terms of factorial series, supplemented by harmonic sums which are algebraically reducible. Complete analytic representations are given for these {15} meromorphic functions in the complex plane deriving their asymptotic- and recursion relations. A general outline is presented on the way nested harmonic sums and multiple zeta values emerge in higher order calculations of zero- and single scale quantities.

Subjects: subject: 621.3 Electrical Engineering, Electronics

description: Electric stimulation of auditory nerve by cochlear implants has been a successful clinical intervention to treat the sensorineural deafness. However, various micro-anatomical factors have not been considered in the state of the art models while studying the interaction between the applied electric field and the auditory nerve. The present finite element modeling study suggests that the modiolus porosity and tissue heterogeneity significantly alter the electric field distribution in the Rosenthal’s canal and thereby affect the cochlear implant functionality.

description: A De Bruijn cycle is a cyclic sequence in which every word of length $n$ over an alphabet $\mathcal{A}$ appears exactly once. De Bruijn tori are a two-dimensional analogue. Motivated by recent progress on universal partial cycles and words, which shorten De Bruijn cycles using a wildcard character, we introduce universal partial tori and matrices. We find them computationally and construct infinitely many of them using one-dimensional variants of universal cycles, including a new variant called a universal partial family.

description: Desires to accomplish net-zero carbon emissions are bringing carbon farming opportunities to farmers in the United States. But carbon markets and carbon agreements raise several important legal issues. This paper discusses three relevant concerns: uncertainty over the legal nature of carbon credits, incompatibility between farming practices and additionality and permanence components of carbon credits, and the lack of governance and infrastructure in the carbon market. Two critical questions arise: whether carbon credits are the appropriate mechanism for incentivizing carbon farming and whether governmental involvement is necessary to bring order to the carbon market.

description: The successfully development of the Netherlandsâ€™ Agri & Food sector in the last 70 years by maximizing the production at minimal costs has led to a situation where the Netherlandsâ€™ animal sectors are now responsible for a high national contribution to environmental impacts. These are acidification of nature areas (mainly by NH3), global warming (CH4) and biodiversity loss. Improvements and reductions have been achieved, to various extents, by single-issue approaches (policy) and solutions in the biophysical production system. Further strong improvements on all environmental aspects are needed, without causing trade-offs and negative side effects. This is a huge challenge for typical highly populated regions as the Netherlands with intensive livestock production and very critical societies. Therefore, the Netherlandsâ€™ Dairy chain has set goals for 2030 to increase the sustainability on the topics of climate, welfare, grazing, biodiversity, environment, new business model, land based farming and safety in the yard. Also, a coalition of dairy sector organizations have proposed a number of management practices to reduce ammonia emission, i.e. dilution of manure, more grazing and lowering protein in ration. Besides these ambitions, strategic aspects of resilience, needs and best practices of dairy farmers involved in two EU projects will be discussed. Some innovative technical practices dealing with environmental management will be demonstrated.

Lattice Fermions Based on Higher-Dimensional Hyperdiamond Lattices

Year: 2009
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: In this paper we generalize to higher dimensions several types of fermion actions on the hyperdiamond lattice including a two-parameter class of minimal-doubling fermions "Creutz fermion" and a simple fermion with sufficient discrete symmetry "BBTW fermion". Then it is shown that they possess some properties in common with the four-dimensional case: BBTW fermions in higher even dimensions inevitably yield unphysical degrees of freedom. Creutz fermions are defined on the distorted lattices, and they lose the high discrete symmetry of the original lattices. We also find properties specific to the higher-dimensional cases. The parameter range for Creutz action to yield minimal-doubling and physical fermions becomes narrower with the dimension getting higher, thus it becomes more and more difficult to realize minimal-doubling. In addition, we generalize the subspecies of Creutz and BBTW actions including a new class of minimal-doubling actions "Appended Creutz action".

A variety of funders, publishers, and scientific organizations around the world refer to re3data within their guidelines and policies, recommending the service to researchers looking for appropriate repositories for storage and discovery of research data. The presentation focuses on the development of the Conceptual Model for User Stories for the re3data service. Since its launch in 2012, re3data has been designed to support open science activities. The registry serves the needs of heterogeneous user groups, first of all aimed at researchers searching for suitable repositories to find and deposit research data. In addition, re3data contributes to other open science infrastructures as a valuable source of metadata about research data repositories. To better understand the needs of its users the re3data COREF project conducted a stakeholder survey. Participants were also invited to join an associated online workshop to further discuss their requirements and recommendations (see Report). The presentation introduces on the most important findings from these activities and introduce common use cases of re3data. It addresses how re3data currently interlinks with several other services and how the integration of third-party information can be realized.

description: As farms increase in complexity producers require more resources to help them develop sound business management strategies. Historically, peer groups gained popularity through use in supporting participants mental health. More recently they have been utilized in many industries, including agriculture, as a professional development tool. Although a farmerâ€™s main motivation for joining a peer group may be professional in nature, developing and following business strategies is proven to positively impact farmers mental health. The benefits of peer groups also can affect the next generation of farm managers who are less likely to follow a business plan, and more susceptible to job-related stress. Regardless of the farmâ€™s current position in their process of succession, the members benefit from the opportunity to learn from their fellow members and be a part of a community where they can be open and vulnerable. To achieve the benefits of a peer group elements should be incorporated into the groupâ€™s organization. Structural elements include a trained facilitator, confidentiality agreement, pre-determined meeting logistics, and rules around roles and member curation. Peer groups are a powerful management tool for developing business management strategies which will help the next generation of producers succeed.

description: An ultraviolet cutoff dependent on the chemical potential as proposed by Casalbuoni {\it et al} is used in the su(3) Nambu-Jona-Lasinio model. The model is applied to the description of stellar quark matter and compact stars. It is shown that with a new cutoff parametrization it is possible to obtain stable hybrid stars with a quark core. A larger cutoff at finite densities leads to a partial chiral symmetry restoration of quark $s$ at lower densities. A direct consequence is the onset of the $s$ quark in stellar matter at lower densities and a softening of the equation of state.

description: This study looks at the impact of monetary policy on South African agriculture making use of the linkages that exist between gross value of agricultural production, real effective exchange rate, monetary policy rate and agricultural credit using annual data from 1971-2020 and empirically investigates the impact of monetary policy on agricultural production in South Africa using econometrics model such as unit root test, co-integration and vector error correction method. The results showed that, in the long-run monetary policy rate, agricultural credit and real effective exchange rate have significant impact on gross value of agricultural production. In conclusion, polices that tend to discount rates should be encourages in order to increased gross value of agricultural production, this can be achieved through increasing productivity in agriculture, improve investment in commercial agriculture and food production, improve quality of production and improvement of marketing system. Agricultural policy makers and monetary policy makers work closely together in designing and implementing monetary policy in South Africa in order to boost agricultural productivity.

description: The main objective the study was to assess the impact of the erosion of existing preferential trade access on the economy of Lesotho using a Social Accounting Matrix (SAM) and Computable General Equilibrium model (CGE). The erosion of preferential trade access negatively affect Lesothoâ€™s international trade, as textile is the countryâ€™s largest export industry by far. It appears also as the result of erosion the textile industry reduce the quantity of textile products exported; price of imported textiles increase and the quantity decrease, as a result, negatively affect Lesotho householdâ€™s welfare measured in terms of equivalent variation (EV), particularly urban area. The probable effect on some macro-economic variables cannot be regards as significant. The erosion of preferential access trade certainly illustrates the need for Lesotho to strive towards diversification of export products. Export diversification is a complex issue. It is not simply a matter of looking for the next miracle product to give a magic answer. It is about providing a solid infrastructure within an economy and building upon that foundation this includes strong regional and global linkages. It is about where to put your priorities in order to maximise the marginal gain to the economy of Lesotho.

Maximally-localized Wannier functions for GW quasiparticles

description: We review the formalisms of the self-consistent GW approximation to many-body perturbation theory and of the generation of optimally-localized Wannier functions from groups of energy bands. We show that the quasiparticle Bloch wave functions from such GW calculations can be used within this Wannier framework. These Wannier functions can be used to interpolate the many-body band structure from the coarse mesh of Brillouin zone points on which it is known from the initial calculation to the usual symmetry lines, and we demonstrate that this procedure is accurate and efficient for the self-consistent GW band structure. The resemblance of these Wannier functions to the bond orbitals discussed in the chemical community led us to expect differences between density-functional and many-body functions that could be qualitatively interpreted. However, the differences proved to be minimal in the cases studied. Detailed results are presented for SrTiO_3 and solid argon.

description: We construct a mathematical model analogous to quantum field theory, but without the notion of vacuum and without measurable physical quantities. This model is a direct mathematical generalization of scattering theory in quantum mechanics to path integrals with multidimensional trajectories (whose mathematical interpretation has been given in a previous paper). In this model the normal ordering of operators in the Fock space is replaced by the Weyl-Moyal algebra. This model shows to be useful in proof of various results in quantum field theory: one first proves these results in the mathematical model and then "translates" them into the usual language of quantum field theory by more or less "ugly" procedures.

description: We present results of numerical self-consistent field (SCF) calculations for the equilibrium mechanical unfolding of a globule formed by a single flexible polymer chain collapsed in a poor solvent. In accordance with earlier scaling theory and stochastic dynamics simulations findings we have identified three regimes of extensional deformation: (i) a linear response regime characterized by a weakly elongated (ellipsoidal) shape of the globule at small deformations, (ii) a tadpole structure with a globular "head" coexisting with a stretched "tail" at intermediate ranges of deformations, and (iii) an uniformly stretched chain at strong extensions. The conformational transition from the tadpole to the stretched chain is accompanied by an abrupt unfolding of the depleted globular head and a corresponding jump-wise drop in the intrachain tension. The unfolding-refolding cycle demonstrates a hysteresis loop in the vicinity of the transition point. These three regimes of deformation, as well as the first-order like transition between the tadpole and the stretched chain conformations, can be experimentally observable provided that the number of monomer units in the chain is large and/or the solvent quality is sufficiently poor. For short chains, on the other hand, under moderately poor solvent strength conditions, the unfolding transition is continuous. Upon an increase in the imposed end-to-end distance the extended globule retains a longitudinally uniform shape at any degree of deformation. In all cases the system exhibits a negative extensional modulus in the intermediate range of deformations. We anticipate that predicted patterns in force-deformation curves for polymer molecules in poor solvent can be observed in single molecule atomic spectroscopy experiments.

Special attention is paid to the consistency of the pairing interaction and normal self-energy contributions. We find that pairing gaps obtained from low-momentum interactions depend only weakly on approximation schemes for the normal self-energy, required in present energy-density functional calculations, while pairing gaps from hard potentials are very sensitive to the effective-mass approximation scheme.

Functionning And Challenges Of Eu Food Quality Schemes In Poland â€“ Perspective Of Producers And Consumers

description: As a part of EU quality policy related to agricultural and food products, in 1992, a system of protection of traditional and regional products (Food Quality Schemes FQS) was introduced in the European Union. The system aims to protect the names of specific products, to promote their unique characteristics, linked to their geographical origin as well as traditional know-how. Poland is one of the largest EU countries in terms of its population and the size of its agricultural sector, however, involvement of agri-food producers in the Food Quality Schemes certification is limited. The main aim of the study was to identify current problems encountered by producers in Poland and to develop a set of recommendations that may support growth of the market of FQS products in Poland. Findings indicated that there are many problems disrupting the functioning of the Polish FQS market. On one hand, most products are characterized by low added value and this makes them difficult to distinguish on the market and therefore easily exposed to counterfeit. On the other hand, there are also PDO and PGI products with greater added value, but the lack of collective action from producers groups reduces potential effect that could result from the economy of scale. Furthermore, especially for PDO products, a limited number of certified producers and small cultivation areas constraints the use of effective marketing strategies, hindering producersâ€™ ability to gain more visibility for their produce. As a consequence, Polish FQS producers are not able to create more profitable market niches, often selling their certified products at regular market prices, without the expected price premium. A further significant problem signalled by producers of PDO, PGI, and TSG products is the indirect and illicit use of the protected names by counterfeit products.

description: Anisotropic pair breaking close to surfaces favors the chiral A phase of the superfluid $^3$He over the time-reversal invariant B phase. Confining the superfluid $^3$He into a cavity of height $D$ of the order of the Cooper pair size characterized by the coherence length $ξ_0$ - ranging between 16 nm (34 bar) and 77 nm (0 bar) - extends the surface effects over the whole sample volume, thus allowing stabilization of the A phase at pressures $P$ and temperatures $T$ where otherwise the B phase would be stable. In this Letter, the surfaces of such a confined sample are covered with a superfluid $^4$He film to create specular quasiparticle scattering boundary conditions, preventing the suppression of the superfluid order parameter. We show that the chiral A phase is the stable superfluid phase under strong confinement over the full $P$-$T$ phase diagram down to a quasi-two-dimensional limit $D / ξ_0 = 1$ , where $D = 80$ nm. The planar phase, which is degenerate with the chiral A phase in the weak-coupling limit, is not observed. The gap inferred from measurements over the wide pressure range from 0.2 to 21.0 bar leads to an empirical ansatz for temperature-dependent strong-coupling effects. We discuss how these results pave the way for the realization of the fully gapped two-dimensional $p_x + ip_y$ superfluid under more extreme confinement.

description: Introduction: This study aimed to compare 10–12-year-old Qatari male soccer players (n = 45) regarding different dimensions (anthropometric, academic and physical performance). Methods: Anthropometric parameters (body mass, fat percentage (%BF), body mass index (BMI)) academic achievement (mathematics and science grade point average [GPA]) and physical performance [Yo-Yo Intermittent Recovery Test (level 1), squat jumps (SJ), counter-movement jumps (CMJ), stork balance test, 10 and 15 m sprint tests, T-half test for change-of-direction (CoD) ability, hand-grip strength, medicine ball throw (MBT)] were measured. Schoolchild soccer players were divided into three groups: 12-year-old players (U12; n = 16), 11-year-old players (U11; n = 14), 10-year-old players (U10; n = 15). Results: Apart from mathematics, Yo-Yo IR1 and 10 m sprint, all performance parameters showed significant age effects. The largest age-related difference was observed for 15 m sprint (p < 0.001). Both adjacent age groups displayed significant differences for 15 sprint (U10 vs. U11: p = 0.015; U11 vs. U12: p = 0.023). Concerning academic performance, a significant age effect was found for science (p < 0.001). There was a main age effect on academic performance difference between U10 and U11 (p = 0.007). Academic parameters did not correlate with any physical performance parameter or anthropometric parameter. The strongest correlations were detected for body height and agility T-half test (r = −0.686) and medicine ball throw (r = 0.637). The biological maturity was strongly correlated with handgrip strength (r = −0.635). Discussion: Soccer coaches and physical education teachers can use these data as reference values for evaluation of school-aged soccer players, and for ascertaining specific training targets. Obviously, short sprinting ability and aerobic capacity are not functions of age and need a specific training for significant improvements.

description: Der Beruf der Forschungsmanager*innen hat sich in den letzten zehn Jahren in Deutschland rasant weiterentwickelt und quantitativ wie qualitativ einen großen Sprung nach vorne getan. Inzwischen gilt das Wissenschaftsmanagement als adäquater Weg, um nach der Promotion ins Berufsleben zu starten und wird an vielen Stellen aktiv beworben. Wie sehen dann aber die Möglichkeiten der Karriereentwicklung von Forschungs-manager*innen aus, wenn der Einstieg geschafft ist? Wer ist verantwortlich für die eigene berufliche Weiterentwicklung? Wie könnte ein kreatives eigenes Karrieremanagement aussehen? Was verstehe ich überhaupt unter Karriere?

In dem Workshop haben wir einen Reflexionsraum für die Beantwortung dieser und weiterer Fragen eröffnet und dabei die aktuelle Diskussion um alternative Karrieremodelle – jenseits des klassischen Aufstiegs – einbezogen. Mit unserem Angebot möchten wir Impulse in die Community geben und erste bzw. weitere Schritte der Teilnehmer*innen unterstützen, um eigene individuelle Lösungen zu entwickeln und neue Pfade zu entdecken.

description: Methods. We analyse two observations taken with the Low Energy Transmission Grating Spectrometer of Chandra. We investigated the spectral response to a sudden flux decrease by a factor of 5, which occurred during the second observation. Results. We detect a highly ionised absorption component with an outflow velocity of -4670 km/s, one of the highest outflow velocity components observed in a Seyfert 1 galaxy. The spectra contain a relativistic O VIII Ly alpha line, and four absorption components spanning a range in ionisation parameter xi between 0.07 and 3.19. An emission component producing radiative recombination continua of C VI and C V appears during the low state. The black body temperature decreases with the drop in flux observed in the second observation. Conclusions. For all absorber components we exclude that the ionisation parameter linearly responded to the decrease in flux by a factor of 5. The variability of the absorber suggest that at least three out of four detected components are located in the range 0.02-1 pc. ABRIDGED

description: Obecnie jednym z najważniejszych wyzwań dla europejskiej kultury akademickiej jest rozwój zasad uczciwości akademickiej (Research Integrity – RI) i etyki badań (Research Ethics – RE) na uniwersytetach. W tekście przedstawiono dwie główne strategie zakorzenienia badań naukowych i innowacji na uczelniach wyższych. Pierwsza z nich łączy liberalno-technokratyczny model uczelni z indywidualistycznym podejściem do praktyk naukowych – etyka badawcza i uczciwość badawcza są częścią ścieżek osobistych karier edukacyjnych i zawodowych. Druga strategia wynika z definicji nauki jako wspólnej wartości i odnosi się do zbiorowej wizji uczelni – budowanie kultury rzetelności naukowej jest podporządkowane realizacji społecznych ról nauki i etosu naukowego. W obliczu masowego rozwoju szkolnictwa wyższego zarówno wizje uczelni, jak i sama idea jednego modelu etyki są utopijne – to model zarazem pożądany, jak i nieosiągalny. Prezentowany artykuł jest oparty na wynikach badań przeprowadzonych w ramach projektu Path2Integrity, finansowanego z programu Horyzont 2020.

description: Researchers are hearing from many sides that their data must be made FAIR, and are often presented with many services that sound very complicated. This presentation shows that there are first steps along a FAIR journey that any researcher can take, and it briefly presents the Data Stewardship Wizard as a way to find out further steps that are suitable for any project specifically. The presentation also attempts to show that an investment in FAIR Data Management can be and should be beneficial to the project and its outcomes, not only to hypothetical re-users of data. This presentation was given in the third of a workshop series by the European Commission, titled "Maximizing investments in health research: FAIR data for a coordinated COVID-19 response".

A systematic approach to bowing and its application in violin playing

description: The aim of this research was to formulate systematic studies for the right-arm to achieve finer outcomes in violin performance. As modern violin practice involves the marking of numerical symbols on the score to indicate left-hand 'fingerings' it is necessary to question why no equivalent system is utilised for the training of the right-arm. Although a system for the notation of bow divisions was formulated by French violinist Lucien Capet over one hundred years ago, its use is virtually unidentified in modern violin playing and teaching. The research method adopted in this project was performance-oriented and focused on incorporating Capet's eight-part bow division notation system into daily analytical practise allowing for core movements of the right-arm and the distribution of the bow to be documented and made habitual for the performance situation. Critical reflections on the process and specifically the application into key performance repertoire are provided in this exegesis, which contextualises the research conducted. The exegesis and folio of performances are equally weighted (50/50) for examination. The associated performance folio contains recordings of various solo and chamber works by composers Bach, Mozart, Ysa‚àöv¿e, Brahms, Handel, Debussy, Franck, Strauss, Gragnani, Weber, Charlton and De Falla. The findings of this study were that setting parameters for bow distribution generated a higher level of response to address combinations of colour, timbre, mood and articulation. Notation of bow distribution is not to be understood as a rigid barrier or impediment to personal expression. On the contrary, once habitualised, it provides full awareness and control of the right arm, resulting in a refined, and highly nuanced regulation of sound to convey the desired musical expression.

description: The intricate connection between climate change and biodiversity conservation highlights the need for integrated approaches to address the challenges of ecological preservation and climate mitigation. Climate change exerts both direct and indirect impacts on biodiversity, affecting the physiology of species to life cycles, distribution, and the intricate web of ecological interactions. Existing pressures are exacerbated by the introduction of new challenges such as habitat destruction, invasive species, and disease outbreaks because of climate change. This combination of threats particularly impacts vulnerable groups like amphibians, demonstrating the urgent need for more dynamic conservation strategies. Traditional conservation methods, including the establishment of protected areas and genetic diversity preservation, must evolve to include 'climate-smart' conservation practices that prioritize actions beneficial for biodiversity in a changing climate. Habitat restoration, leveraging indigenous knowledge, and the integration of biodiversity considerations into climate-smart policies are crucial components of a comprehensive response to these environmental challenges. International agreements like the Kunming-Montreal Agreement and the Paris Agreement establish standards and targets, such as the 30x30 Target, that synergize biodiversity conservation alongside climate change mitigation. Urgently needed is a more effective and efficient global governance structure to manage Earth system tipping points, preventing ecological and climate crises. Immediate action is advocated to adhere to the 1.5°C temperature rise limit set by the Paris Agreement. Comprehensive climate action goes beyond carbon metrics, requiring a holistic strategy that acknowledges the intertwined nature of climate dynamics and biodiversity that can ensure the long-term protection of ecosystems.
