The Consumption and Diversity Variation Responses of Agricultural Pests and Their Dietary Niche Differentiation in Insectivorous Bats

open access: yesAnimals
Insectivorous bats are generalist predators and can flexibly respond to fluctuations in the distribution and abundance of insect prey. To better understand the effects of bats on arthropod pests, the types of pests eaten by bats and the response of bats ...

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 ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Disturbance of hibernating bats due to researchers entering caves to conduct hibernacula surveys

open access: yesScientific Reports
Estimating population changes of bats is important for their conservation. Population estimates of hibernating bats are often calculated by researchers entering hibernacula to count bats; however, the disturbance caused by these surveys can cause bats to

Graman Revisited Once Again: A Reanalysis of the Late Holocene Legacy Faunal Assemblage From GB4 Rockshelter, New South Wales

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Tracking the Dynamics of human Colonisation and Adaptation in Central Vanuatu: Preliminary Results From Excavation and Survey at Pangpang, East Efate

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT In October 2022 an extensive archaeological landscape was identified by staff of the Vanuatu Cultural Centre at Pangpang on the east coast of Efate Island in central Vanuatu. It included midden deposits on the banks of the Pangpang River near the sea at Forari Bay where Lapita and Early Erueti‐style pottery sherds were recovered.

Spatio-Temporal Patterning in Primary Motor Cortex at Movement Onset [PDF]

open access: yes, 2017
Voluntary movement initiation involves the engagement of large populations of motor cortical neurons around movement onset. Despite knowledge of the temporal dynamics that lead to movement, the spatial structure of these dynamics across the cortical ...

Increased Elbow Valgus Torque During Pitching Is Not a Risk Factor for Medial Elbow Injuries in Young Baseball Pitchers: A Prospective Cohort Study

open access: yesArthroscopy, EarlyView.
Purpose To examine the relationship between elbow valgus torque during pitching and the occurrence of medial elbow injuries in young baseball pitchers prospectively. Methods Between 2019 and 2023, 361 male pitchers aged 9 to 12 years were enrolled. Pitchers with a history of elbow injury or who had not served as pitchers in baseball games for ≥1 year ...
