This paper reviews ideas on the relationship between the ecology of clades and their distribution. Ecological biogeography represents a tradition that dates back to ancient times. It assumes that the distribution of organisms is explained by factors of present environment, especially climate. In contrast, modern systematics, following its origins in the Renaissance, concluded with Darwin that ‘...
reserches show that relationship between human and residential places is based upo both emotional and identity structures. in other words, habitat place is not only the creator of a part of humanistic identity but also form a kind of sentimental and emotional bond that may result in tendency to maintain closeness to a specific place. therefor, formaton of emotional and identity relationship wit...
Understanding what governs community assembly and the maintenance of biodiversity is a central issue in ecology, but has been a continuing debate. A key question is the relative importance of habitat specialization (niche assembly) and dispersal limitation (dispersal assembly). In the middle of the Loess Plateau, northwestern China, we examined how species turnover in Liaodong oak (Quercus wuta...
CrossMark ARTICLE INFO ABSTRACT Article history: Data from large-scale biological inventories are essential for understanding and managing Earth's ecosystems. The Forest Inventory and Analysis Program (FIA) of the U.S. Forest Service is the largest biological inventory in North America; however, the FIA inventory recently changed from an amalgam of different approaches to a nationally-standardi...
EUBrazilOpenBio is a collaborative initiative addressing strategic barriers in biodiversity research by integrating open access data and user-friendly tools widely available in Brazil and Europe. The project deploys the EU-Brazil Hybrid Data Infrastructure that allows the sharing of hardware, software and data on-demand. This infrastructure provides access to several integrated services and res...
—Modeling approaches that relate known occurrences of species to landscape features to discover ecological properties and predict geographic occurrences have seen extensive recent application in ecology, systematics, and conservation. A key component in this process is estimation or characterization of species’ distributions in ecological space, which can then be useful in understanding their p...
An objective and reliable assessment of wildlife movement is important in theoretical and applied ecology. The identification and mapping of landscape elements that may enhance functional connectivity is usually a subjective process based on visual interpretations of species movement patterns. New methods based on mathematical morphology provide a generic, flexible, and automated approach for t...
—Understanding patterns in terms of the mechanistic processes that produce them is the essence of ecology. However, many studies merely document nonrandom patterns of species coexistence without providing insight into the structuring mechanisms and their scale dependence. Moreover, few studies address the mechanisms driving functional diversity. The objectives of this study were to document emp...
Centaurea glastifolia, a plant species from the Asteraceae family, is distributed in the Northwest of Iran. This study carried out to determine suitable habitats and habitat connectivity of Centaurea glastifolia in three Provinces of West Azarbayejan, East Azarbayejan and Ardabil. Seven habitat variables and 36 presence points were selected for habitat modelling using six habitat distribution m...
Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...
