Species distribution modelling for conservation of an endangered endemic orchid

AoB Plants, 2015
Navasota ladies'-tresses is an orchid native to eastern and central Texas. It was listed as endangered by the U.S. Fish and Wildlife Service in 1982 and by the State of Texas soon afterwards. Wang et al.

Using camera traps to study the elusive European Wildcat Felis silvestris silvestris Schreber, 1777 (Carnivora: Felidae) in central Germany: what makes a good camera trapping site?

Journal of Threatened Taxa, 2019
Camera traping is a widely used method to study the abundance and population density of elusive terrestrial animals.  To make full use of this method, it is necessary to obtain high photographic capture rates of the target species.

Genome evolution in an endangered freshwater mussel [PDF]

arXiv
Nearly neutral theory predicts that evolutionary processes will differ in small populations compared to large populations, a key point of concern for endangered species. The nearly-neutral threshold, the span of neutral variation, and the adaptive potential from new mutations all differ depending on N_e.

Long-time behavior of a reaction-diffusion model with strong Allee effect and free boundary: effect of a protection zone [PDF]

published in Journal of Dynamics and Differential Equations, 2021, 2019
This paper concerns the effect of the (separated/connected) protection zone for the evolution of an endangered species on the reaction-diffusion equation with strong Allee effect and free boundary. We give a description of the long-time dynamical behavior of the problem of two types protection zones with the same length.

Distilling Named Entity Recognition Models for Endangered Species from Large Language Models [PDF]

arXiv
Natural language processing (NLP) practitioners are leveraging large language models (LLM) to create structured datasets from semi-structured and unstructured data sources such as patents, papers, and theses, without having domain-specific knowledge. At the same time, ecological experts are searching for a variety of means to preserve biodiversity.

Multi-population comparison of resource exploitation by island foxes: Implications for conservation

Global Ecology and Conservation, 2014
Imperiled island foxes are inherently resource-limited by their insular ecology. We examined food use on all 6 islands where they occur to assess resource exploitation patterns.

Location Privacy in Conservation [PDF]

arXiv, 2019
The growing public nature of academic journals along with current best practices of sharing primary data for scientific research are profoundly valuable for the understanding of a species and their conservation efforts. On the other hand, public spatial data on endangered species may be easily abused by wildlife criminals. In this paper, we discuss how

U.S. Conservation Policy Reconsidered [PDF]

Research related to the Endangered Species Act tends to take the presence of that policy as given and focus on issues of implementation and effects. This paper seeks to reconsider U.S. conservation policy entirely.
