Dynamic species distribution models of Antarctic blue whales in the Weddell Sea using visual sighting and passive acoustic monitoring data

Aim: Species distribution models (SDMs) are essential tools in ecology and conservation. However, the scarcity of visual sightings of marine mammals in remote polar areas hinders the effective application of SDMs there. Passive acoustic monitoring …

Fin whale (Balaenoptera physalus) distribution modeling on their Nordic and Barents Seas feeding grounds

Understanding cetacean distribution is essential for conservation planning and decision-making, particularly in regions subject to rapid environmental changes. Nevertheless, information on their spatiotemporal distribution is commonly limited, …

Dynamic species distribution models in the marine realm: predicting year-round habitat suitability of baleen whales in the Southern Ocean

Species distribution models (SDMs) relate species information to environmental conditions to predict potential species distributions. The majority of SDMs are static, relating species presence information to long-term average environmental …

Multi-year presence of humpback whales in the Atlantic sector of the Southern Ocean but not during El Niño

Humpback whales are thought to undertake annual migrations between their low latitude breeding grounds and high latitude feeding grounds. However, under specific conditions, humpback whales sometimes change their migratory destination or skip …

Static species distribution models in the marine realm: the case of baleen whales in the Southern Ocean

Aim: Information on the spatiotemporal distribution of marine species is essential for developing proactive management strategies. However, sufficient information is seldom available at large spatial scales, particularly in polar areas. The Southern …

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 …

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 …

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 …

The Desert Beauty Calopieris eulimene: a butterfly new to Egypt (Insecta: Lepidoptera)

Download PDF Ahmed El-Gabbas & Francis Gilbert 2016 The Desert Beauty Calopieris eulimene: a butterfly new to Egypt (Insecta: Lepidoptera) Zoology in the Middle East 62:3(279-281) 10.1080/09397140.2016.1202984 The butterfly genus Calopieris Aurivillius, 1898 has only one species: the Desert Beauty Calopieris eulimene (Klug, 1829) (Ackery, Smith, & Vane-Wright, 1985), which is a rare Afrotropical species considered to be one of the most xerophilic butterflies in Africa (T.
