A scientific team at the Doñana Biological Station – CSIC studied the competitive interactions between several ant communities in three different habitats in Doñana.

Gene expression can be modulated by epigenetic modifications, which may lead to a rapid adaptation to environmental stress. After stress cessation, changes in gene expression could be reversed, which would allow organisms to maintain their phenotype under transient environments, but this mechanism is poorly understood. Social stress downregulates a gene directly involved in pheomelanin synthesis (Slc7a11) by changing DNA m5C levels, avoiding cellular damage caused by stress.

In the present study, the effects of nocturnal light level (i.e. lunar phase and artificial lighting) on the activity of wall geckos was evaluated (Tarentola mauritanica) of different ages in an anthropic environment. Data on individual behaviour were collected by direct observation and later examined by means of generalized linear mixed model (GLMM) analysis.

The specific spatial distribution and habitat association are major issues in ecology and conservation. Nesting sites of five cliff-nesting raptors (Egyptian vulture [a locally extinct species], common buzzard, osprey, common kestrel, Barbary falcon), and common raven were located and georeferenced on one of the most biodiverse hotspot within the Canary Islands (Teno, Tenerife).
