The peculiar syrinx of Rhea americana (Greater Rhea, Palaeognathae)

Vertebrate Zoology, 2013
This work studied the skeletal and muscular syringeal anatomy of Greater Rhea (Rhea americana) throughout postnatal ontogeny, by using muscle staining and differential coloring of cartilage and bone techniques. Anatomical syrinx dissections on four adults (one female and three males) and eight unsexed chicks, were made.

FOGS: A SNPSTR Marker Database to Combat Wildlife Trafficking and a Cell Culture Bank for Ex‐Situ Conservation

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.

The Lithornithiformes (Aves) from the early Eocene London Clay of Walton‐on‐the‐Naze (Essex, UK)

Papers in Palaeontology, Volume 11, Issue 1, January/February 2025.
Abstract We describe multiple partial skeletons and isolated bones of the palaeognathous Lithornithiformes from the early Eocene London Clay of Walton‐on‐the‐Naze (Essex, UK). The well‐preserved specimens are assigned to at least four species of the taxa Lithornis and Pseudocrypturus. Two species of Lithornis are identified as L. nasi and L.

Plant and frugivore species characteristics drive frugivore contributions to seed dispersal effectiveness in a hyperdiverse community

Functional Ecology, Volume 39, Issue 1, Page 238-253, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal by frugivores is a crucial step of the life cycle of most plants, influencing plant population and community dynamics. Although very important for most ecosystems, we are just beginning to understand which are the mechanisms driving frugivore‐mediated ...

Capybaras (Hydrochoerus hydrochaeris) Generate Grazing Lawns and Maintain Plant Diversity in Neotropical Savanna

Applied Vegetation Science, Volume 28, Issue 1, January/March 2025.
We show that excluding native grazers from a South American grassy ecosystem leads to strong declines in plant species richness over an 18‐month period. Our results imply that severely defaunated South American ecosystems have retained plant taxa and functional trait complexes that can tolerate intense herbivory, identifying herbivore reintroductions ...
