Anthropogenic and Natural Determinants of the Population of a Sensitive Species: Sage Grouse in Nevada [PDF]

open access: yes
This paper uses Nevada data to conduct regression analyses of the relationship between sage grouse (Centrocercus urophasianus) population sizes and potential causal factors.

A scalable variational inequality approach for flow through porous media models with pressure-dependent viscosity

open access: yes, 2017
Mathematical models for flow through porous media typically enjoy the so-called maximum principles, which place bounds on the pressure field. It is highly desirable to preserve these bounds on the pressure field in predictive numerical simulations, that ...

Nest Survival and Failure in Ruffs Breeding on Grazed Coastal Meadows

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
ABSTRACT Nest survival is a key determinant of birds' breeding success, particularly in ground‐breeding birds, where nest predation is a major cause of reproductive failure. Birds can maximise their nesting success by optimising aspects of the sociospatial environment of a nest, for example, by reducing the risk of predation or flooding.

A model-based decision support framework for siting communication tower infrastructure to reduce adverse effects on a sagebrush-obligate species

open access: yesGlobal Ecology and Conservation
The ongoing expansion of human enterprise into remote environments has contributed to degradation and fragmentation of ecosystems globally, reducing plant and animal species’ habitats and viability.

Mechanical Stretching of Proteins: Calmodulin and Titin

open access: yes, 2004
Mechanical unfolding of several domains of calmodulin and titin is studied using a Go-like model with a realistic contact map and Lennard-Jones contact interactions.

Non‐Invasive eDNA Reveals the Ecological and Genetic Status of the Western Capercaillie (Tetrao urogallus aquitanicus) in the Eastern Pyrenees

open access: yesEnvironmental DNA
Environmental changes and human activities in the Anthropocene era are likely to alter population size, structure, and genetic diversity of many species. Long‐term monitoring is therefore essential to assess these impacts and enable informed conservation

Advocating better habitat use and selection models in bird ecology [PDF]

open access: yes, 2018
Studies on habitat use and habitat selection represent a basic aspect of bird ecology, due to its importance in natural history, distribution, response to environmental changes, management and conservation.
