Impact of Forest Fragmentation and Associated Edge Effects on Tropical Forest Biodiversity in North West Madagascar, Assessed via Ecoacoustics

Animal Conservation, EarlyView.
Deforestation in the tropics is a major threat to forest‐specialist animals, many of which are already threatened with extinction. We assessed how forest fragmentation and its associated edge‐effects impact animal biodiversity in Northwest Madagascar using soundscape analysis and acoustic indices.

Anticipating cosmetic emulsion stability using a novel multi‐analytical approach

International Journal of Cosmetic Science, EarlyView.
A novel combination of granulometry, turbidimetry and rheology enables early detection of cosmetic emulsion instability—reducing assessment time from 30 to 8 days. This rapid method distinguishes stable from unstable emulsions under identical conditions, offering a powerful tool for formulation screening and industrial quality control.

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Comparative evaluation of the attractiveness of new polyethylene screens versus West African tiny target for the control of tsetse flies

Medical and Veterinary Entomology, EarlyView.
The material has no significant difference in captures (non‐shiny cotton‐polyester screens vs. the shiny polyethylene screens), but the vertical screen attracted significantly more G. tachinoides for each type of material. Full white horizontal screen was significantly lower than the reference WATT.

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

Vegetation trajectories over 150 years of temporary ponds created in the Camargue delta (Southern France)

Restoration Ecology, EarlyView.
Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In
