The Siberian Crane (Grus leucogeranus) is the third rarest and most endangered crane species in world. This study aimed at predicting effect of climate change on habitat suitability breeding range wintering Asia Wetlands by using ensemble modeling under future scenarios before year 2050. In this regard, we used 4 methods, Surface Range Envelop (SRE), Random Forest (RF), Classification Tree Anal...
Species distribution models (SDMs) are often used to predict the impact of climate change on future species. However, application species-level SDMs ignores intraspecific variation and can be problematic. The aim study was incorporate information into compare predictions subspecies- in a widespread African tree species, Sclerocarya birrea (marula). We bioclimatic variables terrain roughness ind...
Biological invasions pose significant challenges in the Anthropocene, impacting ecosystem biodiversity and functioning. Ecological Niche Modeling is widely used to evaluate potential areas at risk of invasions, aiding prevention invasive-species expansion guiding conservation efforts freshwater ecosystems. The main objectives this study were model ecological niche remaining suitable habitat for...
Trade of non-native reptiles is an important and increasing driver biodiversity loss often compromises the standards required for protection. However, growing interest in as pets has posed serious concerns to wildlife managers conservationists. Instituting effective policies regarding requires a thorough understanding potential range species new environments. In this study, we used ensemble ten...
Japanese Spanish mackerel ( Scomberomorus niphonius ) is an important commercial fish species with a seasonal migratory habit in China. At present, no study has reported the variation of its potential suitable habitat. Therefore, we used biomod2 ensemble model to predict habitat S. different seasons through current distribution sites and future environmental variables. Our results showed that h...
Abstract This study examines 10 different taxa within the genus Abies identified in circum-Mediterranean area: A. alba , borisii-regis, cephalonica, cilicica, nebrodensis, nordmanniana subsp. equi-trojani, nordmanniana, numidica, pinsapo var. marocana and . We assess potential distribution of these species Mediterranean Basin, most Central-Northern Europe Asia Minor through analysis 8 bioclimat...
Geospatial modeling is one of the most powerful tools available to conservation biologists for estimating current species ranges of Earth's biodiversity. Now, with the advantage of predictive climate models, these methods can be deployed for understanding future impacts on threatened biota. Here, we employ predictive modeling under a conservative estimate of future climate change to examine imp...
Climate change could amplify the extinction risk of endemic species, and is even greater for species occupying high elevations mountain ranges. In this study, we assessed climatically suitable habitat only Nepalese bird spiny babbler (Turdoides nipalensis), predicted extent future (2050 2070) under two climate scenarios (SSP2-4.5 SSP5-8.5). We used georeferenced occurrence points alongside ecol...
The Tucuman Parrot (Amazona tucumana), which is restricted to Southern Yungas forest of Argentina and Bolivia, has not recovered from severe population declines in the 1980s. We assessed habitat conservation targets for this species and asked, ‘‘What constitutes the right target?’’ For species with small ranges, maximizing the proportion of the range under protection is an established strategy ...
Species distribution models are scarcely applicable to invasive species because of their breaking of the models' assumptions. So far, few mechanistic, semi-mechanistic or statistical solutions like dispersal constraints or propagule limitation have been applied. We evaluated a novel quasi-semi-mechanistic approach for regional scale models, using historical proximity variables (HPV) representin...
