Vertebrate diversity and biomass along a recovery gradient in a lowland tropical forest

Biotropica, Volume 57, Issue 1, January 2025.
Deforestation of tropical forests has resulted in large areas of secondary forests with the potential for biodiversity to re‐establish to levels usually found in old‐growth forests. This study shows that diversity and biomass of mammals and birds in regenerating forests can recover to old‐growth levels within a relatively short time.

Paleoneurology of stem palaeognaths clarifies the plesiomorphic condition of the crown bird central nervous system

Journal of Morphology, Volume 285, Issue 6, June 2024.
We describe the nearly complete digital endocasts of the brain and bony labyrinth of the neotype specimen of Lithornis vulturinus, a palaeognathous bird from the early Eocene of Europe. Lithornis may provide the clearest insights to date into the neuroanatomy of the ancestral crown bird, combining an ancestrally unflexed brain with a caudally oriented ...

Global diversity and adaptations of avian eggshell thickness indices

Ibis, Volume 166, Issue 2, Page 534-550, April 2024.
The amniote eggshell is a fundamental aspect of the embryo life‐support system, protecting it from UV light, microbes and mechanical damage, while regulating gas exchange and providing calcium for growth. The thickness of eggshells is highly diverse across modern birds and influences multiple eggshell functions, yet the selective pressures driving ...

A proxy for brain‐to‐endocranial cavity index in non‐neornithean dinosaurs and other extinct archosaurs

Journal of Comparative Neurology, Volume 532, Issue 3, March 2024.
Illustration of the endocranial doming, which can provide a proxy for the brain‐to‐endocranial cavity index, using the endocast of an adult of the iguanodont dinosaur Proa valdearinnoensis as an example. Abstract Although the brain fills nearly the entire cranial cavity in birds, it can occupy a small portion of it in crocodilians.

Nuclear parcellation and numbers of orexinergic neurons in five species of larger brained birds

Journal of Comparative Neurology, Volume 532, Issue 3, March 2024.
Immunohistochemical staining for orexin‐A reveals the orexinergic neuronal population in the hypothalamus of the Congo gray parrot. The arrangement of orexinergic neurons in the avian hypothalamus shows distinct conservation across avian species, unlike the variance noted in mammals. Abstract The orexinergic/hypocretinergic system, while having several

Dynamic changes in ocular shape during human development and its implications for retina fovea formation

BioEssays, Volume 46, Issue 1, January 2024.
We propose that fovea formation involves dynamic and asymmetric changes in ocular shape in humans and other species with foveated eyes. Abstract The human fovea is known for its distinctive pit‐like appearance, which results from the displacement of retinal layers superficial to the photoreceptors cells.

The Struthionidae and Pelagornithidae (Aves: Struthioniformes, Odontopterygiformes) from the late Pliocene of Ahl al Oughlam, Morocco

, 2008
The Pliocene locality of Ahl al Oughlam is situated at the southeastern limit of the city of Casablanca, in Morocco, on an ancient seashore of the Atlantic Ocean. It has yielded a very rich vertebrate fauna (macro- and micromammals, birds, reptiles, amphibians and fishes) including both terrestrial and marine forms. On the basis of biostratigraphy, the
