Local Adaptation and Osmoregulatory Mechanisms of the Copepod Acartia tonsa Under Low Salinity Stress. [PDF]

Mol Ecol
ABSTRACT Salinity—an essential factor shaping marine species distributions—is rapidly shifting due to global change, yet the mechanisms of salinity tolerance and adaptation remain poorly understood. We investigated local adaptation in the calanoid copepod Acartia tonsa, a broadly distributed marine species that thrives in the brackish Baltic Sea. Using

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Genomic investigations of successful invasions: the picture emerging from recent studies. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Invasion biology aims to identify traits and mechanisms that contribute to successful invasions, while also providing general insights into the mechanisms underlying population expansion and adaptation to rapid climate and habitat changes. Certain phenotypic attributes have been linked to successful invasions, and the role of genetics has been

Patterns of Population Genomic Variation and Evolutionary History of European Hake in the Northeastern Atlantic. [PDF]

Ecol Evol
We use for the first time whole‐genome sequencing to explore current and historical patterns of genetic diversity in European hake in the Northeastern Atlantic, focusing on the recently expanded distribution range in the North Sea. Genomic data revealed a complex scenario with three populations: North Sea, Celtic Sea and Portugal.

Multigenerational exposure of microplastics on the microbiota of E. affinis (copepod): a comparative study between biodegradable and nonbiodegradable microplastics

Frontiers in Ecology and Evolution, 2023
The accumulation of plastic debris around the world, especially in marine environments, has been well documented during the past decades. Recent studies have found that inorganic surfaces of microplastics (MPs) can be used by microorganisms as living ...

A New Method for Microplastics Identification in Copepods

Frontiers in Environmental Chemistry, 2022
This study investigates several methods to identify microplastics (MPs) of small size ranges (<10 µm) in the copepod Eurytemora affinis collected in the Seine estuary (France) and identified using epifluorescence microscopy and Raman microspectroscopy.

RATE OF ENVIRONMENTAL CHANGE AND ADAPTATION IN THE COPEPOD EURYTEMORA AFFINIS [PDF]

Evolution, 1982
The calanoid copepod Eurytemora affinis (Poppe) is a year-round inhabitat of the Chesapeake Bay, experiencing temperatures ranging from 0 C to 30 C. Since the generation time is only about three weeks at 15 C, much less than the seasonal cycle, individuals do not experience the entire range of temperatures.

Does the Ice Age legacy end in Central Europe? The shrinking distributions of glacial relict crustaceans in Lithuania

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 10, Page 1003-1013, October 2023., 2023
Abstract Glacial relict crustaceans are characterized by their affinity for cold and well‐oxygenated waters and their limited dispersal ability. They occur in large, deep lakes of Northern and Central Europe and North America, with their distributions shaped by glaciation events.

A bioenergetics‐based index of habitat suitability: Spatial dynamics of foraging constraints and food limitation for a rare estuarine fish

Transactions of the American Fisheries Society, Volume 152, Issue 5, Page 650-671, September 2023., 2023
Abstract Objectives Habitat suitability models can guide restoration efforts in freshwater and estuarine ecosystems by synthesizing important habitat attributes in a single index. Several important elements of the foraging arena of Delta Smelt Hypomesus transpacificus, a small, zooplanktivorous fish, were quantified using a model that combined ...

Generation of functional noncanonical donor splice sites by +2T variants in breast cancer susceptibility genes: impact on clinical interpretation. [PDF]

J Pathol
Abstract Splicing dysregulation is a relevant mechanism of pathogenicity for variants in disease susceptibility genes. Variants affecting the critical intronic +1 and +2 GT nucleotides of the 5’ splice sites (5'ss) are generally strong indicators of pathogenicity.
