Hypoxia affects thousands of km2 of marine waters all over the world, and has caused mass
mortality of marine animals, benthic defaunation and decline in fisheries production in many …

The present study describes the seasonal changes of the fish species composition in three
areas of the main channel of the Caeté River estuary, Brazil. The fish faunas of each habitat …

Hypoxia has a profound effect on fish reproduction and development. Behavioral studies
revealed that hypoxia can affect courtship behaviors, mate choice, and reproductive efforts …

Harvesting wild populations may contrast or reinforce natural agents of selection and
potentially cause evolutionary changes in life‐history traits such as growth and maturation …

Understanding responses of marine species to temperature variability is essential to predict
impacts of future climate change in the oceans. Most ectotherms are expected to adjust their …

In order to adequately monitor biodiversity trends through time and their responses to
natural or anthropogenic impacts, researchers require long time series that are often …

Planktivorous capelin is a key species in the Barents Sea, being of great importance in the
exploitation of plankton production in this subarctic region. However, in years with a …

The beach seine fishery is performed regularly along the Portuguese coast in shallow water
sandy areas. The catches and discards of this fishery were studied from March until …

An ecosystem's ability to maintain key functions during environmental change is largely
determined by its biodiversity. We compared fish species composition, richness, diversity …

Spatial and temporal variability of fish assemblage in the Shatt Al-Arab River was studied
from December 2011 to November 2012. Water temperature, salinity, dissolved oxygen and …
