Behavioral Response of Oyster Valve Gape to Ecological Conditions in an Intermittently Closed EstuaryNARA Subscribed
Low-inflow estuaries are highly variable and productive habitats. Organisms in these systems must cope with constantly changing conditions. This study investigates the continuous response of oysters to environmental stimuli in a small, low-inflow, estuary, Los Peñasquitos Lagoon (LPL), in San Diego, California, USA. The oysters were placed on a mooring at near-surface and near-bottom locations and instrumented with noninvasive...
Sea Urchin Removal as a Tool, Not a Solution: Practical Lessons for Kelp Restoration in Aotearoa New ZealandNARA Subscribed
The increasing awareness of the extent of urchin barrens and impacts of sea urchin overgrazing on rocky reefs in Aotearoa New Zealand has led to a rapid increase in the use of sea urchin removal as a tool for kelp forest restoration. Here, we review these restoration projects, focusing on three case studies, with the aim to provide context on what urchin removal does and does not achieve and guidance on when, where and how it...
Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events. Mercuria is a species‐rich genus of freshwater gastropods (33 extant nominal species) wid...
Sugarcane yellow leaf virus (SCYLV) occurs in all sugarcane producing regions of the world and can reduce yield up to 50%. In Louisiana, USA, infections are asymptomatic, making reliable detection paramount to avoid unintentional disease spread. While reverse-transcription polymerase chain reaction (RT-PCR) assays are available, they may lack sensitivity. This study aimed to develop a reliable and sensitive assay appropriate f...
Through Arctic amplification, global climate change is projected to disproportionally affect high-latitude environments. Additionally, the geographical heterogeneity and complex terrain of mountains promote climate-driven ecological change on fine spatial scales. We used a high-resolution convection-permitting regional climate model (HCLIM) and a state-of-the-art dynamic vegetation model (LPJ-GUESS) to explore mid-twentieth ce...
Under global climate change, co-occurrence of ocean acidification (OA) and warming poses a substantial threat to marine ecosystems. The present study focused on the Strait of Georgia within the Northeast Pacific region, where conditions of aragonite undersaturation exist year-round across the majority of the water column, with further intensification expected under OA. These conditions coincide with persistent rises in mean se...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Early Imaging Biomarkers of Cartilage Strain After ACL Reconstruction Predict Patient Pain and Altered Knee LoadingNARA Subscribed
Purpose To investigate temporal evolution of cartilage strain and relaxometry following ACL reconstruction, and examine associations between MRI metrics, pain, and knee loading patterns during gait as potential early markers of cartilage degeneration. Methods Twenty-five participants (15 female, 10 male; mean age 25.6 years) undergoing ACL reconstruction completed MRI assessments at 6 and 12 month post-surgery, including displ...
Investigating the effects of biogenic amines on the dominance hierarchy in the small carpenter bee, Ceratina calcarataNARA Subscribed
Biogenic amines are highly conserved across animal species and aid in the regulation of movement, behavior, motivation, temperature, blood pressure, and endocrine secretion. Within eusocial species, such as the honey bee Apis mellifera , biogenic amines are responsible for modulating traits associated with higher levels of sociality, such as division of labor. In Ceratina calcarata , a facultatively social bee species, mothers...
