Hydrology and trophic flexibility structure alpine stream food webs in the Teton Range, Wyoming, USA

open access: yesEcosphere, Volume 15, Issue 10, October 2024.
Abstract Understanding biotic interactions and how they vary across habitats is important for assessing the vulnerability of communities to climate change. Receding glaciers in high mountain areas can lead to the hydrologic homogenization of streams and reduce habitat heterogeneity, which are predicted to drive declines in regional diversity and ...

A comprehensive comparison of sex-inducing activity in asexual worms of the planarian Dugesia ryukyuensis: the crucial sex-inducing substance appears to be present in yolk glands in Tricladida

open access: yesZoological Letters, 2018
Background Turbellarian species can post-embryonically produce germ line cells from pluripotent stem cells called neoblasts, which enables some of them to switch between an asexual and a sexual state in response to environmental changes.

Enhancing metabarcoding of freshwater biotic communities: A new online tool for primer selection and exploring data from 14 primer pairs

open access: yesEnvironmental DNA, Volume 6, Issue 4, July–August 2024.
We used water samples from natural systems in Canada to create an eDNA metabarcoding dataset with 14 primer pairs that were evaluated in silico, in vitro (five mock communities), and in vivo (water samples from aquaria). The dataset was used to evaluate our new free, user‐friendly online tool (SNIPe), created to derive subsets of informative, cost ...

Modelling the potential for local management practices to offset climate change impacts on freshwater macroinvertebrate communities

open access: yesFreshwater Biology, Volume 69, Issue 3, Page 435-449, March 2024.
Abstract A robust understanding of the interactions between global and local anthropogenic stressors is crucial for ecosystem management in the Anthropocene. Manipulative experiments in the laboratory or in the field can be used to build knowledge about the physiological and ecological effects of stressors, but predicting the combined landscape‐scale ...

State of knowledge of aquatic ecosystem and fisheries of the Lake Edward System, East Africa

open access: yesAquaculture, Fish and Fisheries, Volume 4, Issue 1, February 2024.
We present the state of knowledge of Lakes Edward, George, and the Kazinga channel, East Africa, from a review conducted to organize existing data and information to support decision making and establish research gaps. Substantial information and data exists on aspects such as extant taxa, water quality and fish catches.
