This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

Artificial Light at Night Alters Both of Nocturnal and Diurnal Pollination Networks in Alpine Meadows [PDF]
Artificial light at night (ALAN) affects plant–pollinator interactions through taxon‐specific changes in pollinator visitation. Reduced Lepidoptera visitation restructures nocturnal pollination networks by decreasing nestedness and increasing modularity, whereas shifts in daytime pollinator assemblages increase connectance in diurnal pollination ...

Diel Vertical Migration: Modelling Light Mediated Mechanisms
Light is generally regarded as the most likely cue used by zooplankton to regulate their vertical movements through the water column. However, the way in which light is used by zooplankton as a cue is not well understood.

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

ABSTRACT Atlantic salmon (Salmo must survive the transition from river to fjord in order to migrate to northern latitudes where they feed and grow at sea. In the River Suldalslågen in southern Norway, hydropower regulated water discharge determines the timing and extent of river flows and fjord currents.

ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...
