Environmental DNA Particle Size Distribution and Quantity Differ Across Taxa and Organelles

Environmental DNA, Volume 6, Issue 5, September–October 2024.
ABSTRACT The use of environmental DNA to detect species is now widespread in freshwater ecology. However, the detectability of species depends on many factors, such as the quantity of eDNA particles available in the environment and their state (e.g., free DNA fragments, organellar, or aggregated DNA particles).

Gender-role alternation in the simultaneously hermaphroditic freshwater snail Physa acuta: not with the same partner [PDF]

, 2018
In simultaneous hermaphrodites, gender conflicts that arise from two potential mates sharing the same gender preference may be solved through conditional reciprocity (or gamete trading).

Food web structures of irrigated rice fields estimated from carbon and nitrogen stable isotopes: Special reference to the role of filamentous green algae as a food resource of aquatic consumers

Ecological Research, Volume 39, Issue 3, Page 318-329, May 2024.
We examined aquatic food web structures in two adjacent rice fields in northeastern Japan using carbon and nitrogen stable isotope ratios. δ13C‐based isotopic mixing model estimated that the majority of herbivores and omnivores, as well as several carnivorous taxa, assimilated carbon derived from filamentous green algae (contributions to carbon ...

Fitness effects of assisted gene flow in an endangered salmonid population

Conservation Science and Practice, Volume 6, Issue 1, January 2024.
This study investigates the impact of assisted gene flow on the fitness of an endangered landlocked salmon population. Our results reveal that while assisted gene flow can have a positive influence on individual growth, it can also lead to decreased survival rates under predation risk.
