Agricultural Fungicide Mancozeb in Leaf Litter Enhances Survival and Growth of Aedes aegypti (Diptera: Culicidae)

Environmental Toxicology, EarlyView.
ABSTRACT Mancozeb is one of the most widely used agricultural fungicides, exhibiting strong efficacy against a broad spectrum of phytopathogenic fungi. However, its widespread application comes at the cost of environmental contamination. Here, we show the effects of Inga vera leaf litter contamination with Mancozeb on life‐history traits of Aedes ...

Suplementação alimentar com vitamina C e desempenho zootécnico de girinos de rã-touro (Rana catesbeiana) = Alimentary supplementation of Vitamin C and the performance indexes of bullfrog tadpoles (Rana catesbeiana)

Acta Scientiarum: Animal Sciences, 2007
Neste trabalho avaliou-se o desempenho zootécnico de girinos de rã-touro (Rana catesbeiana) cuja dieta foi suplementada com vitamina C. Girinos com peso médio inicial de 12,3 mg ± 2 mg foram distribuídos em 16 caixas de água de 40 L, na densidade deum ...

Chytridiomycosis causes high amphibian mortality prior to the completion of metamorphosis

Amphibian populations are undergoing extensive declines globally. The fungal disease chytridiomycosis, caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd), is a primary contributor to these declines.

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

Environmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Resilience in the heights: Elevational filtering preserves taxonomic and functional beta diversity over time against biotic homogenization

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental heterogeneity generates taxonomic and functional beta diversity, but a key question regards whether heterogeneity can maintain functional diversity when global change causes range shifts, potentially causing biotic homogenization by favouring species ...

Fungal Batrachochytrium dendrobatidis infections proliferate during amphibian terrestrial dormancy

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The spread and impact of wildlife pathogens is often seasonal, and identifying the season(s) of highest impact can be critical to biodiversity and public health management.

Spillover dynamics and asynchronous temporal fluctuations in host density and competence drive fungal parasite persistence in multi‐host, seasonal communities

Journal of Animal Ecology, EarlyView.
In this study, the authors develop a new model to show that species contributions to parasite persistence can have strong, asynchronous temporal variability, often limiting the effectiveness of targeted seasonal parasite control. The model is broadly applicable for partitioning who, when, and what drive parasite persistence in multi‐host seasonal ...
