Increased offspring provisioning by large female fish and consequences for reproductive efficiency. [PDF]
Ecol Evol, 2023 (a) A weighted female total length versus egg diameter trendline (red) supports that larger females produce larger eggs. (b) However, when egg diameter is converted to egg volume (red) and further, number of eggs per mL gonad (blue), it demonstrates an egg size‐fecundity trade‐off.

Aquatic Living Resources, 2023 Anadromous European smelt (Osmerus eperlanus) is a keystone species in lake and river ecosystems. In the past and present, stock declines in several of its habitats have been reported. The reasons for this are unclear.

Patterns and Processes of Genomic Evolution Inferred From the Ten Smallest Vertebrate Genomes. [PDF]
Adv Sci (Weinh)By integrating phylogenetic relationships derived from nuclear DNA with population genetic analyses across ten pufferfish species, the genetic differentiation mechanisms underpinning the radiative speciation of the most compact vertebrate genomes has elucidated.

Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding. [PDF]
Ecol EvolWe analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...

CLADOGENESIS AND LOSS OF THE MARINE LIFE-HISTORY PHASE IN FRESHWATER GALAXIID FISHES (OSMERIFORMES: GALAXIIDAE) [PDF]
Evolution, 2001 Switches from migratory (diadromous) to nonmigratory (freshwater) life histories are known to have occurred repeatedly in some aquatic taxa. However, the significance of the loss of diadromy as an initiator for speciation remains poorly understood. The rivers of New Zealand's South Island house a species flock of recently derived nonmigratory galaxiid ...
