Lack of country-wide systematic herpetology collections in Portugal jeopardizes future research and conservation.

Anais da Academia Brasileira de Ciências
Natural History Collections (NHCs) represent the world's largest repositories of long-term biodiversity datasets. Specimen collection and voucher deposition has been the backbone of NHCs since their inception, but recent decades have seen a drastic ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Next-generation sequencing of mixed genomic DNA allows efficient assembly of rearranged mitochondrial genomes in Amolops chunganensis and Quasipaa boulengeri [PDF]

PeerJ, 2016
Recent improvements in next-generation sequencing (NGS) technologies can facilitate the obtainment of mitochondrial genomes. However, it is not clear whether NGS could be effectively used to reconstruct the mitogenome with high gene rearrangement.

Capacity building needed to reap the benefits of access to biodiversity collections

PLANTS, PEOPLE, PLANET, EarlyView.
Global conservation efforts increasingly depend on digitised natural history collections, yet the benefits of this digital data are not equally shared. We analysed biodiversity specimens and citation data from Montserrat and the Cayman Islands to assess who collected these specimens, how they are used, and by whom.

Identity Play: Middle School Youths' Provisional Self‐Making in Horizon‐Expanding STEM Spaces

Science Education, EarlyView.
ABSTRACT This study introduces identity play as an analytic construct for science education to explore improvisational dimensions of middle school students' STEM identity development in multiple out‐of‐school learning experiences focused on environmental problem‐solving.

Evolution of research on global amphibian declines

Conservation Biology, EarlyView.
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

ADVANTAGES OF HOLOTIPUS FOR TAXONOMIC HERPETOLOGY

Holotipus, 2020
This is an open letter to researchers in specimen-based taxonomic herpetology, to bring to your attention a new open-access peer-reviewed journal which emphasizes the importance of type material and voucher specimens in taxonomy and systematics.

An analysis of the linked decisions in the confiscation of illegally traded turtles

Conservation Science and Practice, EarlyView.
Increased enforcement of laws governing the international trade of freshwater turtles is increasing the numbers of confiscated turtles. Decision makers are thus increasingly faced with a complex decision, involving multiple linked agencies, regarding the disposition of turtles of unknown origin and disease status, which creates uncertainty about the ...
