New records of extinct Icacinaceae from Paleocene rainforests of northwestern South America

American Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise This study describes three new records of Icacinaceae—Punctiuga bachue gen. et sp. nov., Palaeophytocrene paramoae sp. nov., and Goweria bacatana sp. nov. from the Paleocene (Selandian–Thanetian) Bogotá Formation in Colombia—improving understanding of the distribution and evolution of this family in the Neotropics.

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

The Anatomical Record, Volume 309, Issue 7, Page 1766-1787, July 2026.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...

The effects of the Richmondian invasion on benthic invertebrate functional diversity during the Late Ordovician

Frontiers in Ecology and Evolution
Rising temperatures and globalization are enabling widespread biotic invasions today, particularly in marine environments. While the long-term consequences of invasion are poorly understood, the fossil record can be used to assess the impacts of past ...

Prediction of the Potential Distribution of Common Pochard (Aythya ferina) and Marbled Teal (Marmaronetta angustirostris) in Iran Under Future Climate Scenarios

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Predicting waterbird habitat changes under future climate scenarios. ABSTRACT Climate change is reshaping ecological communities worldwide, altering species distributions, abundance, and habitat suitability. We modelled the potential distribution of two duck species, the Common Pochard (Aythya ferina) and the Marbled Teal (Marmaronetta angustirostris),

Dental Calculus Formation Is Linked to Diet and Phylogeny in Mammals

Ecology and Evolution, Volume 16, Issue 7, July 2026.
In a survey of > 1600 specimens across all mammalian orders, we found that most species present dental calculus. We found calculus production to be strongly associated with herbivory, and we provide recommendations for the use of dental calculus in collections‐based research. ABSTRACT The oral microbiome is implicated in a wide diversity of fundamental

Simulating past and future refugia for temperate trees in northern Italy

Ecography, Volume 2026, Issue 7, July 2026.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...
