Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

open access: yesThe Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

open access: yesAnimal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

open access: yesAnimal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

‘School is their whole world’: Teachers' perspectives on loneliness among children and adolescents from England and mainland China

open access: yesBritish Educational Research Journal, EarlyView.
Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.

Revisiting the Carbon Footprint of Single‐Use Technologies in Biomanufacturing: A Bottom‐Up Analysis Reveals a Paradigm Shift

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The biopharmaceutical industry increasingly relies on single‐use technologies (SUT) for operational flexibility. For a long time, SUT was considered more sustainable than stainless‐steel (SST) systems due to water and energy savings. This study re‐evaluates this paradigm via a detailed bottom‐up analysis of the SUT carbon footprint at the 2000

Comparative Assessment of Landsat‐8 and SPOT‐7 Satellite Data With Field Spectral Measurements for Estimating Plant Diversity in Sandy Grasslands

open access: yesBiological Diversity, EarlyView.
We compared Landsat‐8 OLI, SPOT, and hyperspectral data for estimating vascular plant diversity in China's Hunshandak Sandland. SPOT data showed the strongest correlation with alpha diversity, followed by hyperspectral data, with Landsat‐8 performing the weakest.

Differential Elevational Diversity Between Overstory and Understory in Tropical Forests

open access: yesBiological Diversity, EarlyView.
Tropical forest overstory and understory exhibit contrasting elevational α‐diversity patterns (unimodal vs. bimodal). Community differentiation is driven by species turnover of dominant rather than rare species, highlighting the need for vertically stratified conservation across the full elevational gradient.

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.
