How to assess the potential habitat integrating landscape dynamics and population research, and how to reintroduce animals to potential habitats in environments highly human disturbed are still questions to be answered in conservation biology. According to behavioral research on Elaphurus davidians, we have developed a suitability index and a risk index to evaluate the potential habitats for th...

Potential larval habitats of the mosquito Culex tarsalis (Coquillett), implicated as a primary vector of West Nile virus in Wyoming, were identified using integrated remote sensing and geographic information system (GIS) analyses. The study area is in the Powder River Basin of north central Wyoming, an area that has been undergoing a significant increase in coalbed methane gas extractions since...

Background and objectives: Mountain habitats, due to their climatic conditions, are considered to be very sensitive areas and generally have less plant diversity compared to the lower elevations. Unfortunately, in the past years, due to human attacks, parts of these areas have been destroyed and now some areas are either devoid of vegetation or have very little vegetation. Since Crataegus and B...

Climate change impacts tree species differentially by exerting unique pressures and altering their suitable habitats. We previously predicted these changes in suitable habitat for current and future climates using a species habitat model (DISTRIB) in the eastern United States. Based on the accuracy of the model, the species assemblages should eventually reflect the new quasi-equilibrium suitabl...

Prunus eburnea (Spach) Aitch. & Hemsl. is an endemic plant species of Iran-Afghanestan, which has medicinal and nutritional value and distributed in extensive parts of arid and semi-arid ecosystems of Iran. The aims of this study were to investigate the life forms and chorology of associated perennial plant species and biodiversity indices in 52 habitats. Habitats were divided into ten main reg...

1. Current views of anthropogenic environments emphasize the extreme novelty of urban and industrial ecosystems. Proponents of reconciliation ecology argue that we need to use such habitats to conserve biodiversity, given the inadequacy of natural reserve systems. 2. Some of the harshest anthropogenic ecosystems may be able to support indigenous biodiversity due to their structural or functiona...

BACKGROUND Artemisia annua L. is an important source for artemisinin, a potent drug for treating malaria. This study aims to map and predict the potential geographic distribution of A. annua L. in China. METHODS The Geographic Information System for traditional Chinese medicine (TCM-GIS) was developed and used to map the potential geographic distribution of A. annua L. RESULTS Climatic, eda...

and abandonment is causing considerable woodland expansion in many mountainous areas of Europe, with potential repercussions on conservation-sensitive species typical of open habitats. We examined the potential impact of such changes on an alpine golden eagle population, by estimating the ranges potentially used by the eagles for foraging through different techniques (concentric circles of diff...

Understanding population-level responses to novel selective pressures can elucidate evolutionary consequences of human-altered habitats. Stream impoundments (reservoirs) alter riverine ecosystems worldwide, exposing stream fishes to uncommon selective pressures. Assessing phenotypic trait divergence in reservoir habitats will be a first step in identifying the potential evolutionary and ecologi...

Anthropogenic modification of habitats may reduce the resources available for native species, leading to population declines and extinction. These same habitats often have the highest richness of non-native species. This pattern may be explained if recently human-modified habitats provide novel resources that are more accessible to non-native species than native species. Using non-native birds ...
