Probiotic effects on rumen ciliate community in dairy cows: A multi taxonomic assessment [PDF]

Anais da Academia Brasileira de Ciências
The rumen ciliate protozoa represent a significant component of the microbial ecosystem in ruminants, contributing to the degradation of complex carbohydrates, intra-ruminal nitrogen recycling, and interactions with methanogenic archaea.

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed biodiversity monitoring across taxa from bacteria to mammals, yet sample collection remains a major bottleneck. Passive sampling via adsorption and entrapment has emerged as a promising alternative to overcome the limitations of conventional active filtration.

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot

American Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Comparison of Environmental DNA Metabarcoding and Trawl Data Highlights Gear Selectivity of Marine Demersal Fish Surveys on the Faroese Plateau

Environmental DNA, Volume 8, Issue 2, March/April 2026.
The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.
