Bath Treatments With Emamectin Benzoate Control Dactylogyrideans Infecting Colossoma macropomum Gills Without Altering Physiology of This Host Fish

Journal of Fish Diseases, Volume 49, Issue 6, June 2026.
ABSTRACT Intensification of fish aquaculture worldwide has led to severe problems of diseases caused by parasitic dactylogyrideans. In this study, the anti‐dactylogyridean efficacy of treating Colossoma macropomum with baths of emamectin benzoate (EMB) was investigated for the first time, along with the effects of this treatment on the haematology and ...

Exiled From Their Own Lands: Indigenist Policies, Oil, and Colonial Plunder in 20th Century Venezuela

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT This article examines the historical displacement of Indigenous peoples in Venezuela, focusing on the links between indigenist policies and the exploitation of natural resources, particularly oil, throughout the 20th century. Using a combined historical and ethnographic approach, it demonstrates how the formation of the Venezuelan nation‐state

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

New Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

Land Degradation &Development, Volume 37, Issue 9, Page 4368-4382, 30 May 2026.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Climate Change Amplifies Rainfall Sensitivity to Deforestation in the Southern Amazon

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Rainfall among the Amazon has been shown to decline sharply once forest loss exceeds a critical threshold, typically around 30%–40%. However, future interactions between climate change and deforestation on this threshold remain unclear. We model their combined effects by 2050 on rainfall and temperature.
