On the selection and effectiveness of pseudo-absences for species distribution modeling with deep learning

Devis Tuia, Benjamin Alexander Kellenberger, Nina Marion Aurélia Van Tiel, Robin Adrien Zbinden, Lloyd Haydn Hughes

Species distribution modeling is a highly versatile tool for understanding the intricate relationship between environmental conditions and species occurrences. However, the available data often lacks information on confirmed species absence and is limited ...

Improved marine debris detection in satellite imagery with automatic refinement of coarse hand annotations

Devis Tuia, Marc Conrad Russwurm, Elif Dilge Gül

Plastic litter is a major environmental hazard that endangers human, animal, and plant health on the planet. A substantial portion of plastic pollutants is washed from rivers and beaches into the oceans and aggregates at the surface as marine debris before ...

Aligning actions with objectives in endangered species recovery plans

Alex Tunas Corzon

To achieve conservation objectives for threatened and endangered species, managers must choose among potential recovery actions based on their efficacy. Yet, a lack of standardization in defining how conservation actions support recovery objectives can imp ...

A pathwise approach to the extinction of branching processes with countably many types

Sophie Myriam Hautphenne

We consider the extinction events of Galton-Watson processes with countably infinitely many types. In particular, we construct truncated and augmented Galton-Watson processes with finite but increasing sets of types. A pathwise approach is then used to sho ...

First quantitative survey delineates the distribution of chimpanzees in the Eastern Central African Republic

Stéphane Joost, Estelle Rochat

Vast, pristine ecosystems and their biodiversity are vanishing globally at frightening speed, but many large tracts of wilderness have not yet been systematically inventoried and important natural populations of threatened species remain poorly characteriz ...

Venting turbidity currents for the sustainable use of reservoirs

Anton Schleiss, Giovanni De Cesare, Sabine Chamoun

Reservoir sedimentation is an ongoing issue, which endangers the sustainability of reservoirs. As well as reducing the capacity of a reservoir, sedimentation causes damage to hydraulic structures such as turbine intakes and bottom outlets. In addition, dow ...

Coalescent inferences in conservation genetics: should the exception become the rule?

Valeria Montano

Genetic estimates of effective population size (Ne) are an established means to develop informed conservation policies. Another key goal to pursue the conservation of endangered species is keeping the connectivity across fragmented environments, to which g ...

Interacting populations in heterogeneous environments

Séverine Vuilleumier Varisco

To optimally manage a metapopulation, managers and conservation biologists can favor a type of habitat spatial distribution (e.g. aggregated or random). However, the spatial distribution that provides the highest habitat occupancy remains ambiguous and num ...

Inferring plant ecosystem organization from species occurrences

Andrea Rinaldo

In this paper, we present an approach capable of extracting insights on ecosystem organization from merely occurrence (presence/absence) data. We extrapolate to the collective behavior by encapsulating some simplifying assumptions within a given set of con ...

Effect of inclined jet screen on turbidity current

Anton Schleiss, Giovanni De Cesare, Christoph Oehy

The sustainable use of reservoirs for irrigation, flood protection, water supply and hydropower may be endangered due to unavoidable reservoir sedimentation. Turbidity currents are the main process for the transport and deposit of sediments in reservoirs, ...
