American Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022 Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

Suitability of Natura 2000 sites for threatened freshwater species under projected climate change
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1872-1887, December 2022., 2022 Abstract As part of the world's largest coordinated network of protected areas, Natura 2000, European Union member states designate special areas of conservation (SACs) to maintain or achieve favourable conservation status for imperilled aquatic species listed under Annex II of the Habitats Directive.

A computed tomography‐based survey of paramedullary diverticula in extant Aves
The Anatomical Record, Volume 306, Issue 1, Page 29-50, January 2023., 2023 Abstract Avian respiratory systems are comprised of rigid lungs connected to a hierarchically organized network of large, regional air sacs, and small diverticula that branch from them. Paramedullary diverticula are those that rest in contact with the spinal cord, and frequently invade the vertebral canal.

The Anatomical Record, Volume 306, Issue 1, Page 5-28, January 2023., 2023 Abstract Antlers are the most conspicuous trait of cervids and have been used in the past to establish a classification of their fossil and living representatives. Since the availability of molecular data, morphological characters have generally become less important for phylogenetic reconstructions.

The Anatomical Record, EarlyView., 2023 Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

The Anatomical Record, EarlyView., 2023 Abstract The Hyaenodonta were the most diverse carnivorous mammals in the European Eocene and were classically divided into three subfamilies: Sinopaninae, Arfianinae, and Proviverrinae, with this latter being the most successful of the three, as it exhibited a much larger geographic and temporal range.

The Anatomical Record, EarlyView., 2023 Abstract The freshwater pleurodiran turtle Neochelys is the best‐represented member of Podocnemididae in the European record, being known by eight Eocene species. The youngest of them is the Bartonian (middle Eocene) Neochelys salmanticensis, from the Duero Basin (Salamanca Province, Central Spain).

The Anatomical Record, EarlyView., 2023 Abstract Anoplotheriines (Mammalia, Artiodactyla) were enigmatic, medium‐ to large‐sized ungulates that lived in Western Europe from the late middle Eocene to the earliest Oligocene. The unusual dental and postcranial specializations of these Paleogene mammals have no equivalent in other Cenozoic or contemporaneous artiodactyls on Holarctic landmasses.

Lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene of Mazaterón (Soria, Spain)
The Anatomical Record, EarlyView., 2023 Abstract The assemblage of lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene locality of Mazaterón (Spain) is described. Considering the rather limited material available for the study, the assemblage shows a moderate diversity with eight taxa corresponding to five different families.

Craniogenetic studies in Sus scrofa: With emphasis on the ‘orbitosphenoid’ problem
The Anatomical Record, EarlyView., 2023 Abstract The orbitosphenoid is a skeletal element of the endocranium of extant mammals. However, it has also been described in many of their fossil ancestors. Craniogenetic studies show that it is composed of two types of bone: first, the cartilaginous ala orbitalis and parts of the trabecular plate are transformed by endochondral ossification; second,
