What drives the evolution of body size in ectotherms? A global analysis across the amphibian tree of life

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 8, Page 1311-1322, August 2023., 2023
Abstract Aim The emergence of large‐scale patterns of animal body size is the central expectation of a wide range of (macro)ecological and evolutionary hypotheses. The drivers shaping these patterns include climate (e.g. Bergmann's rule), resource availability (e.g. ‘resource rule’), biogeographic settings and niche partitioning (e.g.

Reactive binder and aggregate interfacial zones in the mortar of Tomb of Caecilia Metella concrete, 1C BCE, Rome

open access: yesJournal of the American Ceramic Society, Volume 105, Issue 2, Page 1503-1518, February 2022., 2022
Abstract Integrated spectroscopic analyses and synchrotron X‐ray microdiffraction investigations provide insights into the long‐term reactivity of volcanic aggregate components and calcium‐aluminum‐silicate‐hydrate (C‐A‐S‐H) binder in mortar samples from the robust concrete of the sepulchral corridor of the Tomb of Caecilia Metella, 1st C BCE, Rome ...

Geography of roadkills within the Tropical Andes Biodiversity Hotspot: Poorly known vertebrates are part of the toll

open access: yesBiotropica, Volume 53, Issue 3, Page 820-830, May 2021., 2021
We analyzed wildlife roadkill patterns along a road network between tree protected areas in the Andes of Ecuador. Roadkills included poorly known small and endemic vertebrates, such as caecilians (Gymnophiona) and fossorial snakes (Atractus spp.). Most roadkills occurred in areas where roads crossed pasturelands adjacent to natural habitat.

Home Range and Movement Pattern of the Broad-Snouted Caiman (Caiman latirostris) in a Silviculture Dominated Landscape [PDF]

open access: yes, 2020
Information on the home range and movement patterns of Neotropical crocodilians is scarce for most species, despite being essential for developing management and conservation plans.

Molecular phylogeny reveals distinct evolutionary lineages of the banded krait, Bungarus fasciatus (Squamata, Elapidae) in Asia [PDF]

open access: yes, 2023
The banded krait, Bungarus fasciatus is a widespread elapid snake, likely to comprise several distinct species in different geographic regions of Asia. Therefore, based on molecular phylogenetics and comparative morphology data, we present an overview of

Development and evolution of the tetrapod skull–neck boundary

open access: yesBiological Reviews, Volume 95, Issue 3, Page 573-591, June 2020., 2020
ABSTRACT The origin and evolution of the vertebrate skull have been topics of intense study for more than two centuries. Whereas early theories of skull origin, such as the influential vertebral theory, have been largely refuted with respect to the anterior (pre‐otic) region of the skull, the posterior (post‐otic) region is known to be derived from the

Growth Curves of Wild and Reintroduced Broad-Snouted Caimans (Caiman latirostris) and Their Management Implications [PDF]

open access: yes, 2020
We describe body growth functions of broad-snouted caimans (Caiman latirostris) for wild and reintroduced individuals. Snout-vent length (SVL, cm) and age of young individuals and adult females were recorded for two different groups: (Py) animals born in
