Animals regularly experience periods of food uncertainty due to seasonal changes and environmental variability. Further, the changing climate is leading to more variable weather patterns, which alter environmental conditions, and can result in resource distributions being less predictable in space and time. How animals respond to uncertain conditions, and in particular a changing distribution of food resources, remains largely...
Assessing the Progress of Stock Rebuilding in the Northeast Atlantic Against Levels That Can Produce Maximum Sustainable YieldNARA Subscribed
Rebuilding fish stocks to levels above which they produce Maximum Sustainable Yield (MSY) is a management aim for all European commercially exploited stocks. Progress is typically monitored against the fishing mortality that produces MSY in the long term ( F MSY ), however, the corresponding biomass target ( B MSY ) is rarely evaluated nor reported. Here, we analyse a unique database of 73 quantitative ICES stock assessments t...
Using pre-release efficacy as a candidate agent prioritisation tool for the weed Trichocereus spachianus (Caryophyllales: Cactaceae)NARA Subscribed
Pre-release efficacy assessments (PREA) can be used to prioritise the most damaging candidate agents for further studies in biological control programmes against invasive alien plants. This study assessed the efficacy of various potential enemies of Trichocereus spachianus (Riccob.) (Caryophyllales: Cactaceae), an invasive cactus in South Africa, in order to prioritise the most damaging candidates for further studies, includin...
Overlooked seasonal groundwater nutrient fluxes rival anthropogenic point sources across a variable land‐use tidal riverNARA Subscribed
Understanding groundwater–surface water connectivity in tidal freshwater zones is essential for managing ecosystems within the riverine–estuarine continuum. Groundwater discharge is a key source of dissolved nutrient loads that can lead to eutrophication, deoxygenation, and other ecosystem imbalances in coastal environments. However, groundwater is an often‐overlooked nutrient delivery pathway, with limited studies quantifying...
A summary and critique of the various spectrophotometric methods used to quantify C-phycocyanin concentrationNARA Subscribed
A wide range of research has been conducted on various applications and purification methods of C-phycocyanin (C-PC). In the published literature, there has not been consistency in the methods used to determine the concentration of C-PC within solution. This is an important characteristic to accurately determine the efficiency of a C-PC purification process and the quality of a final C-PC product. This brief report aims to cri...
Exploring the activated charcoal adsorption column to improve cosmetic grade C-phycocyanin purification from SpirulinaNARA Subscribed
This study investigates the effectiveness of activated charcoal, a common adsorbent, in various packed column configurations in the context of a process to purify C-phycocyanin (C-PC) from Spirulina . The adsorption column performance is considered in isolation and as part of purification trains, which include chitosan treatment and ammonium sulfate precipitation. Operating parameters of interest included activated charcoal pa...
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...
Predation on Live and Artificial Insect Prey Shows Different Global Latitudinal PatternsNARA Subscribed
Aim Long‐standing theory predicts that the intensity of biotic interactions increases from high to low latitudes. Studies addressing geographic variation in predation on insect prey have often relied on prey models, which lack many characteristics of live prey. Our goals were to explore global latitudinal patterns of predator attack rates on standardised live insect prey and to compare the patterns in predation on live insects...
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...
