Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

open access: yesCladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

To release or not to release? A call for caution when considering wildlife reintroductions

open access: yesConservation Science and Practice, EarlyView.
Conservation efforts often focus on flagship species and short‐term measures such as captive breeding and reintroductions, yet these approaches may benefit from being complemented with a broader view of the factors that influence long‐term recovery. Using examples from management programs in the Iberian Peninsula, we highlight the value of considering ...
