A rapid inventory of amphibians, squamates, and bats of Mata de Plátano Field Station and Nature Reserve, Arecibo, Puerto Rico

open access: yesEcology and Evolution
Puerto Rico harbors a diverse vertebrate fauna with high levels of endemism. However, while several books for vertebrate diversity and local checklists for birds have been published, checklists of amphibians, reptiles, and bats are lacking or nonexistent

Frog in the throat [PDF]

open access: yesNeurology, 2015
A 27-year-old man presented with pain in his throat after a generalized seizure. He had a 2-year history of nighttime seizures and wore dental prosthetics. Upon awakening after the seizure, the patient complained of chest pain and pain in his throat and coughed up some blood. He could not find his front teeth. Physical examination revealed subcutaneous

Neuromorphic Devices and Computing for Sensing, Memory, and Control

open access: yesAdvanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Aplectana artigasi n.sp. (Nematoda: Cosmocercidae) from the Frog Eupsophus calcaratus (Anura: Leptodactylidae) in Southern Chile

open access: yesMemorias do Instituto Oswaldo Cruz, 1997
A new species of nematode found in the intestine of Eupsophus calcaratus (Anura: Leptodactylidae) from Yaldad, Chile (45° 5'S;73° 43'W) is described. This new nematode is compared with other South American species of the genus. Aplectana artigasi differs

The relational nature of citizen science

open access: yesPeople and Nature
Most citizen science research inherently separates the observer (citizen science participant) from the observation (e.g. data point), placing artificial boundaries around what matters and how it comes to matter.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...
