Mr. Mom: Nocomis Embryo‐Burying Effectively Increases Embryo Survival Amidst Predation by All Mutualism Participants

open access: yesEcology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Nest association is a putatively mutualistic mode of reproduction utilized by many fishes of the North American freshwater family Leuciscidae. It is defined by the interaction between one ‘host’ species that builds and maintains a nest, and multiple other species of ‘nest associates’ that spawn upon it.

Contemporary Evolution of an At‐Risk Stickleback Population During a Severe Drought

open access: yesEvolutionary Applications, Volume 19, Issue 1, January 2026.
ABSTRACT Populations can be granted conservation status because they harbour a set of unique traits, evolutionary histories, or ecological roles. Such populations are often isolated and specialised and, as such, can be particularly vulnerable to environmental disturbances.

Evidence for Asian Swamp Eels as an Emerging Threat to Everglades Amphibians

open access: yesFreshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT As amphibian populations around the globe continue to shrink and suffer enigmatic declines, it is critical to use systematic studies to isolate causes and provide management targets for key environmental variables. We sampled the amphibian community at 30 sites dispersed across four large regions of the Everglades (FL, USA).

Quantitative Metabarcoding Reveals the Effects of Ecological Factors and Invasive Species on Functional Diversity of Freshwater Insects

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Aquatic insects are the most biodiverse freshwater animals. DNA metabarcoding data are increasingly used to assess variation in insect communities, but they are rarely integrated with information on the abundance or biomass of different taxa that can provide key insights into their functional responses.
