Concern over rapid global changes and the potential for interactions among multiple threats are prompting scientists to combine multiple modelling approaches to understand impacts on biodiversity. A relatively recent development is the combination of species distribution models, land-use change predictions, and dynamic population models to predict the relative and combined impacts of climate ch...
Biodiversity researchers in different institutions deal with predictive models for species distribution. These models are useful for biodiversity conservation policies. Species distribution modelling tools need large datasets from different sources and use many algorithms. To improve biodiversity science, scientists need to share models, data and results, and should be able to reproduce experim...
Biodiversity researchers develop predictive models for species occurrence and distribution which are useful for biodiversity conservation policies. Species distribution modelling tools need to locate and access large amount of data in different sources and produces results from different algorithms. In this scenario, collaboration is an essential feature to improve this research area. Scientist...
1. Evaluating the distribution of species richness where biodiversity is high but has been insufficiently sampled is not an easy task. Species distribution modelling has become a useful approach for predicting their ranges, based on the relationships between species records and environmental variables. Overlapping predictions of individual distributions could be a useful strategy for obtaining ...
Defining the oceanic habitats of migratory marine species is important for both single species and ecosystem-based fisheries management, particularly when the distribution of these habitats vary temporally. This can be achieved using species distribution models that include physical environmental predictors. In the present study, species distribution models that describe the seasonal habitats o...
1. The ecological niche is a fundamental biological concept. Modelling species’ niches is central to numerous ecological applications, including predicting species invasions, identifying reservoirs for disease, nature reserve design and forecasting the effects of anthropogenic and natural climate change on species’ ranges. 2. A computational analogue of Hutchinson’s ecological niche concept (th...
پراکنش جغرافیایی جنس کوزینیا در ایران با استفاده از 3095 گزارش ثبت شده در منابع و یا بر اساس نمونه های هرباریومی واکاوی گردید. 241 گونه این جنس در تمام کشور گسترده اند، هرچند که حدود یک سوم از گزارش ها از استان های خراسان رضوی، تهران و فارس می باشد. این جنس 135 گونه نادر و 197 گونه انحصاری دارد. بیشترین مقدار برای شاخص حداکثر فاصله میان دو فرد از یک گونه (maxd) 1863 کیلومتر می باشد. استان های خ...
a total of 162 species (s) of rotifera belonging to 40 genera and 20 families examined from loktak lake, an important floodplain lake of northeast india (nei), is one of the richest assemblages of the taxon known from the indian sub-region. it merits biodiversity value as ~40.0% and ~62.0% of species recorded from india and nei, respectively. one species is new to india, 23 species are new to m...
a r t i c l e i n f o Keywords: genetic diversity glacial refugia hindcasting palaeobiogeography Spain species distribution modelling The forests in the Iberian Peninsula have been strongly influenced by past climatic changes, but reconstructing their historical distributions and dynamics is very difficult due to the complex climatic characteristics and relief of the region. Research discipline...
According to the reports of the International Panel Climate Change (IPCC) there is no doubt about climate change occurring. All ecosystems on the earth have being concerned by the effects of climate change. Urmia lake basin and its rivers exposed to numerous anthropogenic stressors such as hydrological, morphological, connectivity and water quality pressures. The main objective of this study is...
