Spread of Amazonian Freshwater Fishes Beyond Their Native Ranges

Fish and Fisheries, Volume 27, Issue 1, Page 56-67, January 2026.
ABSTRACT The spread and establishment of Amazonian species outside their native ranges through activities such as sport fishing, aquaculture, and the ornamental fish industry may lead to ecological changes in recipient ecosystems. We investigated the global distribution of Amazonian freshwater fish (AFF) and conducted a case study in the upper Paraná ...

Losers and Winners Among Baltic Coastal Meadow Plants After 60 Years of Environmental Change

Journal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
In 2024, we replicated a Baltic coastal meadow plant inventory from the 1960s along with mapping habitat in both time steps using aerial imagery. We found that six species have decreased significantly, of which two were not found at all in 2024, although we found no evidence that habitat loss has had any direct effects on population extinctions.

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub‐Arctic Waterbodies in Northern Canada

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Trade Networks and Consumer Practices in Amedeka, Ghana: Negotiating “Nkudzedze” From the Late 19th to Mid‐20th Centuries

American Anthropologist, Volume 127, Issue 4, Page 757-776, December 2025.
ABSTRACT This paper examines local taste practices in the era of “legitimate trade” when the trade in botanical (e.g., palm oil, palm kernel oil, and cocoa) and nonbotanical (e.g., ivory, textiles) commodities replaced the trade in enslaved Africans. Following the 1807 British abolition of the Atlantic trade in enslaved people, the locus of the trade ...

Nitrifiants autotrophes et heterotrophes en zone littorale et estuarienne

, 1984
This study concerns bacterial nitrification in a small estuary of NW France and its outlet. Both autotrophic and heterotrophic nitrifiers were studied. Sediment and water samples were examined for the presence of nitrifiers using an MPN microtechnique. Several isolates were examined in pure culture for specific nitrifying activity.
