Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Finding patterns of distribution for freshwater phytoplankton, zooplankton and fish, by means of parsimony analysis of endemicity Encontrando patrones de distribución para fitoplancton, zooplancton y peces dulceacuícolas por medio de análisis de parsimonia de endemismos

Revista Chilena de Historia Natural, 2008
During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from 18º to 53º S.

Structure and density population of the invasive mollusc Limnoperna fortunei associated with Eichhornia crassipes in lakes of the Middle Paraná floodplain

Journal of Limnology, 2015
The roots of Eichhornia crassipes provide different microhabitats for invertebrates, including substrate for the Asian invasive bivalve Limnoperna fortunei. This work evaluated the density and size structure of L. fortunei on the roots of E. crassipes in

Beta Diversity and Functional Trait Patterns in Ciliate Communities of Mediterranean Temporary Wetlands

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Temporary aquatic ecosystems are critical for biodiversity conservation, particularly in Mediterranean regions. Doñana National Park, in southern Spain, harbours a network of temporary ponds and marshes that support diverse microbial communities. Among them, ciliates play key ecological roles due to their taxonomic and functional diversity and

Micro‐Refuges or Ecological Traps: Context‐Dependent Effects of Rock Pools on Intertidal Biodiversity Across Latitudes

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim We investigated how local‐scale environmental heterogeneity influences biodiversity patterns across broad biogeographic gradients, using intertidal microhabitats as a model system within one of the most environmentally stressful ecosystems on Earth.

Colonization of a Neotropical Reservoir (Córdoba, Argentina) by Ceratium hirundinella (O. F. Müller) Bergh [PDF]

, 2005
Blooms of Ceratium hirundinella (O. F. Müller) Bergh. have been detected in different water bodies in the Neotropical Region since 1990. The colonization began in southern lakes, and during the last decade the dinoflagellate arrived and bloomed in ...

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

Biotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.
