Dark diversity of flea (Siphonaptera) assemblages in South American rodents: Latitudinal and altitudinal gradients

open access: yesEcological Entomology, EarlyView.
The dark diversity of compound flea communities increased from north to south. The dark diversity of compound flea communities increased from lower to higher altitudes. The dark diversity of component flea communities also increased from north to south but did not vary with altitude.

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

open access: yesJournal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Integrating Niche Dimensions to Advance the Ecological Study of the Americas' Smallest Cat: The Guigna in Argentine Patagonia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We present our findings from the first multi‐annual survey of guigna in Argentine Patagonia. We found that habitat use for guignas was negatively affected by the presence of co‐predators and open vegetation; conversely, it was positively affected by the occurrence of thick forests and the presence of potential prey.

Preservation and palaeobiogeography of dinosaur eggs from the Dadaepo Formation (Upper Cretaceous: Cenomanian), Korea

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dinosaur eggs were recovered from the Dadaepo Basin in Busan (south‐east Korea), which is early Late Cretaceous in age and is close to Japan, but the eggs have not been studied. Among East Asian egg‐bearing basins, the Dadaepo Basin is characterized by exceptionally high thermal maturity (c.

Compost legacy effects in active roadside restoration: Medium‐term shifts in plant succession

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Roadside restoration experiment established on volcanic tephra following road construction in Andean Patagonia. A single application of municipal (MC) or biosolids (BC) compost rapidly increased plant cover compared with untreated controls (C) but led to distinct, exotic‐dominated plant communities over 6 years.

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...
