Stochastic processes govern gut bacterial community assembly in a Schistosoma mansoni-transmitting snail, Biomphalaria straminea.

open access: yesPLoS Neglected Tropical Diseases
BackgroundStudies have revealed extensive taxonomic classifications and patterns of gut microbial diversity in snails, with limited focus on community assembly processes.

Infectious Diseases Management in Small‐Scale Freshwater Aquaculture in West Africa: Lessons for Low‐ and Middle‐Income Countries

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Infectious diseases are an increasing threat to food security, small‐scale livelihoods and the sustainability of aquaculture in low‐ and middle‐income countries (LMICs). In sub‐Saharan Africa, aquaculture is expanding rapidly but production systems often remain fragile.

Chemical Composition of the Eggs of the Freshwater Turtle Phrynops hilarii (Chelidae: Testudines) [PDF]

open access: yes, 2019
At oviposition, amniote eggs contain all the nutrients required for complete neonate tissue development. For reptiles and birds, the egg yolk is the main embryonic energy source and is composed predominantly of proteins and lipids, while also providing ...

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

Snail intermediate host occurrence recorded by citizen scientists in rural Uganda and the Democratic Republic of the Congo

open access: yesGigaByte
Snail-borne parasitic diseases, such as schistosomiasis and fascioliasis, pose significant public health and economic challenges worldwide. Schistosomiasis affects over 250 million people globally, with most cases in sub-Saharan Africa, while ...

Salt in the Wound: Assessing Pathogen Susceptibility in Amphibian Populations Across a Gradient of Salt Pollution

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The survival function of nine larval wood frog populations and their viral loads when exposed to FV3. The populations were collected as eggs from a range of salt‐polluted ponds. Viral load data are means ±1 SE. The populations are ordered in terms of the saltiness of their natal ponds.

Genetic Divergence in the Absence of Strong Ecological Differences Between Coexisting White and Common Atlantic Marine Stickleback

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We examined whether the “white” threespine stickleback of Nova Scotia represents a nascent species distinct from sympatric common marine sticklebacks. Genomic analyses revealed that whites form a unique genetic cluster with low but widespread divergence across the genome despite evidence of gene flow, while morphometric and isotopic data indicated ...

Bisphenol A induces superfeminization in the Ramshorn snail Marisa cornuarietis (Gastropoda: Prosobranchia) at environmentally relevant concentrations [PDF]

open access: yes, 2007
Previous investigations have shown that bisphenol A (BPA) induces a superfeminization syndrome in the freshwater snail Marisa cornuarietis at concentrations as low as 1 μg/L.

2D to 3D: Exploring Variation of Niche Dimensionality Across Consumers in a Coastal Arctic Ecosystem and Implications on Interpretation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.
