A research team of the Doñana Biological Station – CSIC has found that greater noctule bats, one of the most threatened bat species in Europe, do not change their shelter when facing predation risk.
The increase in these deaths might be related to the lack of alternative roosts due to the loss of habitat and breeding areas because of human activity

A group of researchers, with the participation of the Doñana Biological Station – CSIC, has carried out a study to know if the predation rate of loggerhead turtle nests changes across thermal habitats and if sea turtles have the ability to choose nest sites with less predatory prevalence.

Egg mortality is one of the main factors affecting life history and conservation of oviparous species. A massive and cryptic colonisation of many leatherback turtle (Dermochelys coriacea) eggs is presented in the most important rookery for the species in Gabon. A total of 163 nests were exhumed at Kingere beach, revealing that only 16.7% of eggs produced hatchlings. In the 59% of the nests, more than half of the eggs were dead and attacked by invertebrates and 94% had at least one egg...

The ecological role of species can vary among populations depending on local and regional differences in diet. This is particularly true for top predators such as the bottlenose dolphin, which exhibits a highly varied diet. Local dietary assessments are therefore critical to fully understand the role of this species within marine ecosystems. Here, stomach content analyses and stable isotope analyses were combined to describe bottlenose dolphins diet in the Gulf of Cadiz.

Weather conditions determine which is the optimal strategy along the daily cycle for lesser kestrels to select a commuting or a hunting strategy. Using micro-GPS and accelerometers Jesús Hernández-Pliego et al. show how lesser kestrels solve these dilemmas.
