Into the Darkness: Unveiling Unexpected Records of the Nonnative Millipede Prosopodesmus jacobsoni Silvestri, 1910 (Polydesmida: Haplodesmidae) in Brazilian Caves

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT This study expands the known distribution of the nonnative millipede Prosopodesmus jacobsoni in Brazil and reports its presence in cave environments for the first time in the country. Based on recently collected material and historical records, the species is shown to maintain stable populations in subterranean systems in the states of ...

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Fish community structure dynamics in cenotes of the Biosphere Reserve of Sian Ka’an, Yucatán Peninsula, Mexico

Revista Mexicana de Biodiversidad, 2013
Cenotes are permanent aquatic systems formed by geomorphologic processes (karst), located in the Yucatán Peninsula. Many of these oligotrophic systems are connected superficially to wetlands during the wet season. We describe the fish community structure

Decadal changes in environmental suitability for the margay (Leopardus wiedii) under anthropogenic pressure in the Yucatán Peninsula

Conservation Science and Practice, Volume 8, Issue 4, April 2026.
This study evaluates how human activities impact margay (Leopardus wiedii) distribution in the Yucatán Peninsula, revealing habitat loss due to agriculture but also recolonization opportunities in abandoned lands. Species distribution models show range contraction (2010–2023), yet margays demonstrate resilience near disturbed habitats.

Multi‐Scale Habitat Selection of Greater Caribbean Manatees in Sian Ka'an Biosphere Reserve, Mexico

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Habitat selection describes population distribution as a function of environmental features. It is a fundamental process with primordial ecological and evolutionary implications. To accurately describe habitat selection, it is important to identify temporal and spatial scales perceived by the population and use these scales when modeling ...
