Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Management and research efforts are failing dolphins, porpoises, and other toothed whales

open access: yesScientific Reports
Despite being subject to intensive research and public interest many populations of dolphins, porpoises, and other toothed whales (small cetaceans) continue to decline, and several species are on the verge of extinction. We examine small cetacean status,

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Identifying species traits that predict vulnerability to climate change

open access: yesCambridge Prisms: Extinction
Accurately predicting the vulnerabilities of species to climate change requires a more detailed understanding of the functional and life-history traits that make some species more susceptible to declines and extinctions in shifting climates.

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

open access: yesThe Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

Interval Timing Is Altered in Male Nrxn1+/− Mice: A Model of Autism Spectrum Disorder

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is characterized by impaired social interactions and communication, and increased repetitive and stereotypical behavior. Neuroimaging shows functional abnormalities in brain areas involved in temporal processing in autistic individuals, and they also show deficits in interval timing.

An Updated DNA Barcoding Tool for Aloe Vera and Related CITES‐Regulated Species

open access: yesConservation Letters
DNA barcoding has revolutionized the identification of illegally traded material of endangered species as it overcomes the lack of resolution encountered with morphological identification.

A Real Option Approach to the Protection of a Habitat Dependent Endangered Species [PDF]

open access: yes
We use a real option approach to determine optimally when a social planner has to stop or resume logging in situations where an endangered species relies on forest habitat for its survival, and that habitat evolves stochastically.

The 3‐Hit Metabolic Signaling Model for Autism Spectrum Disorder: A Summary

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a highly heritable yet environmentally sensitive neurodevelopmental condition whose biological heterogeneity has resisted a unifying causal explanation for over 100 years. The 3‐hit metabolic signaling model proposes that ASD arises from abnormal persistence of an evolutionarily conserved stress‐response ...

Exposure, Extinction, and Cognitive Appraisals in Autistic Adults With Social Anxiety: Evidence From a Structured Speech Exposure Task

open access: yesAutism Research, EarlyView.
ABSTRACT Social anxiety (SA) is highly prevalent among autistic adults, yet little is known about how autistic people respond to common therapeutic strategies, such as exposure tasks. This study examined responses to a structured speech exposure task embedded within an 8‐week modified cognitive–behavioral therapy (M‐CBT) program.
