Sit‐and‐Wait for the Agoutis: Dung Beetle Phoresy on Dasyprocta azarae in a Tropical Forest

Biotropica, Volume 58, Issue 6, November 2026.
ABSTRACT We document the first case of phoresy by dung beetles with a rodent, involving Canthon (Goniocanthon) smaragdulus subviridis and agoutis (Dasyprocta azarae). Camera traps set in a tropical forest recorded 21 phoretic events, with agoutis carrying 1–6 beetles each. This behavior likely enhances how beetles locate fresh dung.

Pollen analysis of the Pleistocene lacustrine succession of Vallo di Diano (Campania, Italy)

, 1996
Five sedimentation facies were recognised: fluvial, fluvio-lacustrine, lacustrine, marshy and alluvial fan. The pollen analysis of the lacustrine succession enabled to point out two 'glacial-interglacial' cycles.

Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, Volume 249, Issue 5, Page 1021-1032, November 2026.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

EMIT Reveals Elevated Calcite Signatures in Shorelines of Lake Powell and Lake Mead Exposed by Drought and Colorado River Management

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Nearly half of Earth’s seasonal freshwater storage variability occurs in human‐managed reservoirs, resulting in large areas of reservoir‐bed that are episodically inundated or subaerially exposed. Here we use hyperspectral data from NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission to map calcite mineral assemblages across ...
