The Biology and Life Sciences Forum retracts the study titled “On the Use of Stereo-Video System to Assess Microhabitat Preferences of the Spanish Toothcarp and Mosquitofish in Coastal Salt Marshes” [...]

Fresh waters are among the most imperiled ecosystems in the world. Not surprisingly, freshwater and diadromous fishes, which show remarkably high levels of endemism, are declining dramatically worldwide. In Portugal, more than 60% of the native fishe...

Populations of freshwater fish species endemic to the Iberian Peninsula have been declining since the mid-20th century, and several types of actions (from in situ to ex situ measurements) have been applied over the past decades for preserving these s...

Populations of freshwater fish species endemic to the Iberian Peninsula have been declining since the mid-20th century, and the captive breeding of highly endangered species is considered to be a useful tool to restock declining populations. A pionee...

The European eel is critically endangered (IUCN, 2020) due to several factors (climate change, barriers to migration, pollution, unsustainable exploitation, illegal trading and poaching, and pathogens). However, the relative effect of these factors c...

This study aimed to analyse the integrated system of red seaweed Kappaphycus alvarezii and clownfish Amphiprion ocellaris. Experiments were performed in a 45 L aquarium under the following controlled conditions: temperature 22 °C, dissolved oxyge...

Brown trout (Salmo trutta) populations living in Mediterranean peninsulas and the surrounding islands belong to old evolutionary lineages that persisted during Quaternary glaciations. Many of these populations inhabit marginal areas along the south l...

Recent climate scenarios predict dramatic changes for the inland region of Portugal, where the increase in air temperature might reach +5 °C by 2100, accompanied by a strong decrease in precipitation and an increase in extreme events. Such foreca...

In Mediterranean streams and rivers in general, aquatic organisms use a specific habitat for rearing, growing, breeding, and wintering. Multiple studies have focused on this subject, but few for the specific purpose of developing suitability models t...

An increasing number of reef fish species have been shown to form spawning aggregations. These aggregations occur at predictable times and places, with participants utilizing single or mixed mating systems. In a lek-like mating system, males establis...
