Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Spatial oxygen heterogeneity in a Hediste diversicolor irrigated burrow [PDF]

open access: yes, 2011
The heterogeneity of oxygen distribution in a Hediste diversicolor burrow environment was investigated in a laboratory experiment using a 6-mm thick tank equipped with oxygen planar optodes. The twodimensional oxygen distribution in a complete burrow was

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

open access: yesAnimal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

OGFRL1 Deficiency Causes Chronic Recurrent Multifocal Osteomyelitis Via Pathologic Osteoclastogenesis, With Therapeutic Response to Tumor Necrosis Factor Inhibitor

open access: yesArthritis &Rheumatology, EarlyView.
Objective To verify the pathogenesis of the opioid growth factor receptor like‐1 (OGFRL1) loss‐of‐function variant (c.30del, p. F10Ffs*110) identified in a patient with chronic recurrent multifocal osteomyelitis (CRMO) and to investigate the underlying mechanism.

Valve Gape Movement of an Endangered Freshwater Mussel During Burrowing

open access: yesHydrobiology
Understanding the behavioral strategies that allow freshwater mussels to persist under environmental stress is essential for their conservation, yet burrowing behavior remains poorly quantified.

Settlement of Macoma balthica larvae in response to benthic diatom films [PDF]

open access: yes
The role of multi-species benthic diatom films (BDF) in the settlement of late pediveliger larvae of the bivalve Macoma balthica was investigated in still-water bioassays and multiple choice flume experiments.

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
