Environmental DNA and Hydroacoustic Surveys for Monitoring the Spread of the Invasive European Catfish ( Linnaeus, 1758) in the Guadalquivir River Basin, Spain.

The European catfish ( Linnaeus, 1758) was introduced into the Ebro Basin in Spain in 1974 for recreational fishing. Since then, the species has spread throughout the country's river basins, reaching the Iznájar Reservoir (Guadalquivir River Basin) in 2011. This area is of great ecological and economic relevance, especially as it includes the Doñana National Park, one of the most important nature reserves in Europe.

Insights on the Evolutionary History and Genetic Patterns of Cuvier, 1797 in the Northeastern Atlantic Using Mitochondrial DNA.

is one of the most harvested octopus species in the world. In the Iberian Peninsula, there are several small-scale fisheries that have a long-term tradition of harvesting octopus. The Asturias fleet (in Northern Spain) has an internationally recognized MSC label for its exploitation.

Neuron-glia interaction at the receptor level affects olfactory perception in adult .

Some types of glia play an active role in neuronal signaling by modifying their activity although little is known about their role in sensory information signaling at the receptor level. In this research, we report a functional role for the glia that surround the soma of the olfactory receptor neurons (OSNs) in adult . Specific genetic modifications have been targeted to this cell type to obtain live individuals who are tested for olfactory preference and display changes both increasing and reducing sensitivity.

Validation of an Optogenetic Approach to the Study of Olfactory Behavior in the T-Maze of Adults.

Optogenetics enables the alteration of neural activity using genetically targeted expression of light activated proteins for studying behavioral circuits in several species including . The main idea behind this approach is to replace the native behavioral stimulus by the light-induced electrical activation of different points of the circuit. Therefore, its effects on subsequent steps of the circuit or on the final behavior can be analyzed.
