High‐Resolution Satellite Imagery Reveals Landscape‐Scale Benthic Habitat Changes in a Turbid Coral Reef

Remote Sensing in Ecology and Conservation, EarlyView.
High‐resolution satellite imagery and landscape metrics revealed a 77% decline in coral‐dominated habitats at Abrolhos Bank between 2010 and 2024, accompanied by macroalgal and zoanthid expansion. Spatial reorganisation indicates increasing fragmentation, homogenisation and loss of reef structural complexity.

Large parameter uncertainty persists in soil food web models integrating stoichiometry, respiration and assimilation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Balancing Fire Regimes and Population Dynamics for the Conservation of a Microendemic Lizard From a Biodiversity Hotspot

Animal Conservation, EarlyView.
Disturbance from fire mediates a potential ecophysiological trade‐off between adult performance and juvenile recruitment in the microendemic lizard Ameivula jalapensis. While open, burned habitats enhance adult thermoregulation and condition, unburned patches remain critical for juvenile thermal optima.

Conservation Priority Areas for Endemic and Threatened Bird Species in the Brazilian Amazon Under Climate Change: A Multifaceted Approach

Animal Conservation, EarlyView.
Climate change is projected to substantially erode taxonomic, phylogenetic, and functional diversity of endemic and threatened birds in the Brazilian Amazon by 2100. Integrating these dimensions with climate refugia revealed priority conservation areas, particularly in the eastern Amazon, highlighting where conservation efforts can best safeguard ...

Carbon stocks of an Oxisol after thirty-eight years under different tillage systems

Revista Brasileira de Engenharia Agrícola e Ambiental, 2016
Soil carbon (C) stock determination can subsidize discussions on the continuity of an agricultural management. This study aimed to evaluate the stocks of total organic C (STOC) and labile C (SLC), and the indices of C lability (CLI), C compartment (CCI ...

Redescription of the First Zoeal Stage of Shrimp Cinetorhynchus rigens (Gordon, 1936) (Decapoda: Rhynchocinetidae) and New Perspectives Including Scanning Electron Microscopy

Acta Zoologica, EarlyView.
ABSTRACT Cinetorhynchus occur mainly in shallow waters of temperate to tropical regions. Among the 28 species of Rhynchocinetidae, there are only six with larval morphology known and the description of the larva of Cinetorhynchus rigens is succinct. Thus, we redescribe the zoea I of C.
