The Critical Role of Coefficients: Updating Allometric Normalisation Constants for Modern Ecology and ModellingNARA Subscribed
Allometry, the scaling of traits or biological rates with body mass, is central to a wide range of ecological research including dynamic food web modelling. There has been extensive focus on exponents (3/4 scaling laws), but little on the coefficients (normalisation constants). Coefficients that have been used since 2006 are derived from limited data and dated methodologies. Here, we compiled a data set of over 1000 genera wit...
Voxel-wise insights into early Alzheimer’s disease pathology progression: the association with APOE and memory declineNARA Subscribed
Longitudinal investigation of the Apolipoprotein E (APOE) genotype’s impact on Alzheimer’s disease (AD) biomarker progression, focusing on amyloid beta (Aβ) accumulation and gray matter (GM) atrophy, integrating cognitive decline and baseline levels. Longitudinal florbetapir-PET and T1-weighted MRI data from 100 cognitively normal (CN) and mild cognitive impaired (MCI) participants both with considerable global Aβ accumulation...
Ecological physiology of recovery from experimental phenology of algal food deprivation in larvae of a sea urchin (Lytechinus pictus)NARA Subscribed
Studies of seasonal breeding of marine invertebrates led to many important and long-standing marine biological “Rules” (e.g., Orton; Crisp; Thorson: 1920–1950s). Currently, the world’s oceans are undergoing rapid rates of change. The extent to which these historically formative “Rules” still apply in the modern ocean is the focus of the current study. Anthropogenic-driven ocean change is altering the phenology of animal reprod...
Seascape Genomics of Red Abalone: Limited Range‐Wide Population Structure and Evidence for Local AdaptationNARA Subscribed
Characterising patterns of genetic diversity including evidence of local adaptation is relevant for predicting and managing species recovering from overexploitation in the face of climate change. Red abalone ( Haliotis rufescens ) is a species of conservation concern due to recent declines from overharvesting, disease and climate change, resulting in the closure of commercial and recreational fisheries. Using whole‐genome rese...
Genomic selection shows improved expected genetic gain over phenotypic selection of agronomic traits in allotetraploid white cloverNARA Subscribed
Key message Genomic selection using white clover multi-year-multi-site data showed predicted genetic gains through integrating among-half-sibling-family phenotypic selection and within-family genomic selection were up to 89% greater than half-sibling-family phenotypic selection alone. Abstract Genomic selection, an effective breeding tool used widely in plants and animals for improving low-heritability traits, has only recentl...
Complementary value of molecular, phenotypic, and functional aging biomarkers in dementia predictionNARA Subscribed
DNA methylation age (MA), brain age (BA), and frailty index (FI) are putative aging biomarkers linked to dementia risk. We investigated their relationship and combined potential for prediction of cognitive impairment and future dementia risk using the ADNI database. Of several MA algorithms, DunedinPACE and GrimAge2, associated with memory, were combined in a composite MA alongside BA and a data-driven FI in predictive analyse...
Optimising the reintroduction of a specialist peatland butterfly Coenonympha tullia onto peatland restoration sitesNARA Subscribed
The two main goals of peatland restoration are habitat improvement and climate change mitigation by reducing greenhouse gas emissions from damaged peatlands and providing a net carbon sink. The biodiversity of specialist peatland species is threatened because of habitat destruction and the large heath butterfly Coenonympha tullia has become a flagship species for peatland ecosystem restoration, with a species reintroduction pr...
Wind dispersed tree species have greater maximum heightNARA Subscribed
Aim We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location Americas, Africa and the Asia‐Pacific. Time period 1970–2020. Major taxa studied Gymnosperms and Angiosperms. Methods We used a dataset consisting of tree inventories from 2821 plots across three biogeographic regions (Americas, Africa and Asia‐Pacific),...
Integrative biological analyses of responses to food deprivation reveal resilience mechanisms in sea urchin larvaeNARA Subscribed
A fundamental question in ecology is how organisms survive food deprivation. In the ocean, climate change is impacting the phenology of food availability for early life‐history stages of animals. In this study, we undertook an integrative analysis of larvae of the sea urchin Strongylocentrotus purpuratus —an important keystone species in marine ecology and a molecular biological model organism in developmental biology. Specifi...
Climate change disrupts the seasonal coupling of plant and soil microbial nutrient cycling in an alpine ecosystemNARA Subscribed
The seasonal coupling of plant and soil microbial nutrient demands is crucial for efficient ecosystem nutrient cycling and plant production, especially in strongly seasonal alpine ecosystems. Yet, how these seasonal nutrient cycling processes are modified by climate change and what the consequences are for nutrient loss and retention in alpine ecosystems remain unclear. Here, we explored how two pervasive climate change factor...
Endangered shark species traded as “cação” in São Paulo during the COVID-19 lockdown: DNA-barcoding a snapshot of productsNARA Subscribed
Background Elasmobranch populations are declining, predominantly driven by overfishing, and over a third of global sharks, rays, and chimeras are estimated to be threatened with extinction. In terms of trade, Brazil is ranked the eleventh-largest shark producer and the top importer of shark meat in the world. Research has shown that elasmobranchs are sold in Brazil under the name “cação” (a generic designation for cartilaginou...
