Molecular investigation of tick-borne pathogens from different regions of Morocco

open access: yesTicks and Tick-Borne Diseases
Tick-borne pathogens are a worldwide threat to public health that can only be mitigated by knowledge on tick-host associations coupled with surveillance of their infection by pathogenic microorganisms. This information is not equally available throughout

Bimodal nesting season in Karoo dwarf tortoises (Chersobius boulengeri)

open access: yesWildlife Biology, Volume 2025, Issue 4, July 2025.
Tortoises in arid, unpredictable regions may use a bet‐hedging strategy of regularly laying small clutches regardless of actual environmental conditions, so that some hatchlings will emerge when conditions are favourable. Karoo dwarf tortoises (Chersobius boulengeri) are endangered in their arid, unpredictable range in South Africa, yet studies of ...

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs

open access: yesThe Anatomical Record, Volume 308, Issue 5, Page 1349-1368, May 2025.
Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.

Zoonotic pathogens associated with Hyalomma aegyptium in endangered tortoises: evidence for host-switching behaviour in ticks?

open access: yesParasites & Vectors, 2012
Background Hyalomma aegyptium is a hard-tick with a typical three-host life cycle. The main hosts are Palearctic tortoises of genus Testudo. However, other hosts can be used by immature ticks for feeding in natural conditions.

Reptile responses to fire across the western Mediterranean Basin

open access: yesConservation Biology, Volume 39, Issue 1, February 2025.
Abstract Effects of anthropogenic activities, including climate change, are modifying fire regimes, and the dynamic nature of these modifications requires identification of general patterns of organisms’ responses to fire. This is a challenging task because of the high complexity of factors involved (including climate, geography, land use, and species ...
