Opportunistic Feeding and Parasite Assemblages in Sei Whales (<i>Balaenoptera borealis</i>) From Southern Chile Revealed by DNA Metabarcoding. [PDF]

Ecol Evol
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.

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

What Drives the Changing Characteristics of Plankton in Floodplain Lakes: Season, Environmental Factors, or Lake Characteristics? [PDF]

Ecol Evol
In this study, we conducted investigations and monitoring on lakes during the wet season and dry season. We studied the structure, taxonomic/functional diversity, community assembly, and niche differentiation of plankton communities, analyzed the biogeographical patterns of plankton communities, and explored the driving factors affecting plankton ...

Trophic niche overlap between native and non-native fishes in central Anatolian lakes, Türkiye. [PDF]

J Fish Biol
Abstract The Central Anatolian region of Türkiye exhibits exceptionally high freshwater fish diversity and endemism and is increasingly exposed to the introduction of non‐native taxa. We examined the diet composition, prey selectivity and interspecific dietary overlap among eight native and five non‐native fish species across seven lakes in Central ...
