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 ...

Managing Brown Rot Disease of Citrus Fruit Using Plant Extracts

Journal of Phytopathology, Volume 174, Issue 2, March/April 2026.
ABSTRACT Brown rot, caused by Phytophthora nicotianae and P. citrophthora, is a major disease of citrus fruit, leading to significant economic losses globally. Conventional fungicides are commonly used to manage this disease, but concerns have been raised due to environmental persistence, human toxicity and the emergence of resistant strains.

Interspecific variation in leaf phenology and its relationship with plant traits in a seasonal tropical forest

Functional Ecology, Volume 40, Issue 2, Page 433-450, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf phenology plays an important role in plant life‐history strategies and in determining ecosystem‐level fluxes of carbon and water. In seasonal tropical forests, leaf phenology is highly variable among tree species, but limited quantitative data have hindered our ...

Burrow Selection by Temminck's Ground Pangolins (Smutsia temminckii) in Northern Botswana

African Journal of Ecology, Volume 64, Issue 1, January 2026.
ABSTRACT In arid and semi‐arid environments, many species use underground burrows for thermoregulation, reproduction, and to reduce predation risk. In Botswana, Temminck's ground pangolins (Smutsia temminckii) shelter in burrows during the day, and burrow density is thought to be a key indicator of habitat suitability for these animals.
