Spatial conservation prioritisation in data-poor countries: a quantitative sensitivity analysis using multiple taxa

Background: Spatial conservation prioritisation (SCP) is a set of computational tools designed to support the efficient spatial allocation of priority areas for conservation actions, but it is subject to many sources of uncertainty which should be …

Fin whale (Balaenoptera physalus) distribution modelling in the Nordic Seas & adjacent waters

Understanding the dynamics of cetacean distribution in ecologically vulnerable regions is essential to interpret the impact of environmental changes on species ecology and ecosystem functioning. Species distribution models (SDMs) are helpful tools …

Modelling habitat suitability of whales in the Southern Ocean

Detailed information on cetacean distribution is crucial to identify large-scale conservation actions and management decisions. Understanding the ecological drivers behind their spatial patterns in the Southern Ocean is complicated by whales’ …

Improved species-occurrence predictions in data-poor regions: using large-scale data and bias correction with down-weighted Poisson regression and Maxent

Species distribution modelling (SDM) has become an essential method in ecology and conservation. In the absence of survey data, the majority of SDMs are calibrated with opportunistic presence-only data, incurring substantial sampling bias. We address …

Reliability of species distribution modelling for wildlife conservation in developing countries

Species distribution models have become essential tools in ecology and wildlife conservation. However, their reliability when used for conservation management is often compromised by many challenges and limitations, as for example the lack of …

Wrong, but useful: regional species distribution models may not be improved by range-wide data under biased sampling

Species distribution modeling (SDM) is an essential method in ecology and conservation. SDMs are often calibrated within one country’s borders, typically along a limited environmental gradient with biased and incomplete data, making the quality …

Conserving Egypt's reptiles under climate change

Climate change has caused range shifts and extinctions of many species in the recent past. In this study, the effects of climate change on Egyptian reptiles were investigated for the first time using species distribution models. Maxent was used to …

Distribution of the Egyptian reptiles under current and future climates

Climate change has caused range shifts and extinctions of many species in the past. In this study, the effects of climate change on Egyptian reptiles, as a representative of the Egyptian fauna, was investigated for the first time using species …

Mammals of Egypt: atlas, Red Data listing and conservation

There are 110 species of mammals recorded from Egypt. The 93 terrestrial species are reasonably well known, but the marine mammals are very poorly known with at least 17 recorded species. Seven taxa are endemic to Egypt: five species) Flower’s …

Testing the accuracy of species distribution models using species records from a new field survey

Species distribution models are a very popular tool in ecology and biogeography and have great potential to help direct conservation efforts. Models are traditionally tested by using half the original species records to build the model and half to …
