Motivation The database initiated by the Mountain Invasion Research Network (MIREN) is one of the few globally implemented standardized vegetation surveys in mountains. The focus is on collecting plant species occurrences at 5‐year intervals along and adjacent to mountain roads spanning elevational gradients, with the goal of providing critical information about the ongoing spread of non‐native plants and the potential impacts...
When more invaders add less: cumulative impact risk saturates in a multi-species invasion of fire-promoting grassesNARA Subscribed
The cumulative ecological risk from invasions is assumed to increase as more species invade. However, we propose that cumulative risk can saturate when multiple, functionally similar species are present, limiting the marginal contribution of newcomers. We explored this idea by quantifying the spatial footprint of climatic suitability for 12 fire-promoting grasses in Hawaii using species distribution models, using the total cli...
Temperature, but not acidification, influences the growth and lipid profile of juvenile sand whiting, Sillago ciliata (Cuvier 1829)NARA Subscribed
Seafood provides an essential source of macro‐ and micronutrients for coastal communities worldwide. Climate change is a key threat to seafood security, altering the sizes, abundances, distributions, physiology and ecological interactions of fisheries species, and increasingly, there is evidence of impacts to seafood nutritional quality. In a 12‐week mesocosm experiment, we tested the influence of projected ocean warming and a...
Catch‐and‐release angling is widespread in marine recreational fisheries resulting from the implementation of enforced minimum legal sizes and increasing uptake of voluntary release. This makes recreational fisheries selective, with high release rates in certain cases. We estimated the post‐release mortality of the boat‐based recreational snapper fishery in northeastern New Zealand by characterising catch‐and‐release practices...
Monitoring evapotranspiration to link agricultural water use with crop yield at sub-field scalesNARA Subscribed
Purpose Scientists and producers have pursued precision agriculture to increase yields and limit environmental impacts. Applying precision agriculture concepts has not been straightforward, however, because complex interactions between soil and weather govern crop growth. We hypothesize that evapotranspiration (ET) is a single metric that captures interactions between plant status, soil, topography, and weather and can be used...
Background Aspects of the gut microbiome, including presence of specific bacterial species and overall community structure, have been linked to the etiology and prognosis of colorectal cancer (CRC). Less is known about the epidemiologic risk factors that are associated with the composition of the microbiota in invasive colorectal tumors. Methods Using tumor and paired normal colorectal tissue samples from a subset of participa...

Time Lags in Biodiversity Data Processing Create the Illusion of an Invasion SlowdownNARA Subscribed
Aim Understanding invasion trends is essential for mitigating the impacts of invasive species, yet their quantification is easily affected by temporal biases. Previous research has identified biases introduced by inadequate field surveying (delayed detection) but has overlooked the time between a species' detection and the communication of that detection in status reports, databases, or checklists –time delays we refer to as d...
Global Homogenisation of Plant Communities Along Mountain Roads by Non‐Native Species Despite Mixed Effects at Smaller ScalesNARA Subscribed
Aim Mountain ecosystems are experiencing increased invasion of non‐native plants. These increases in non‐native species put mountains at risk of biotic homogenisation and a reduction of biodiversity. Our study aims to test if non‐native plant species are contributing to biotic homogenisation along roadways in mountain regions and how this changes along elevation gradients and across spatial scales. Location 18 globally distrib...
Introduction Pesticides can be transported into estuaries via spray drift, ground water contamination and surface runoff. Increasing climatic variability and global pesticide use are likely to increase the exposure of harvested estuarine species, and therefore seafood consumers, to agrichemicals. Post-harvest processing strategies present opportunities to reduce pesticide residues in seafood and so mitigate consumer exposure....
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...
The red rock crab, Cancer productus , is primarily harvested by a recreational fishery, with a small commercial harvest in California. Although relatively large, meat yields are low because the legs are small, and meat is largely confined to the claws. We investigated the potential for a claw‐only harvest for this species. Although hand removal is used in the stone crab fishery, it caused > 90% post‐harvest mortality in red ro...
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...
