Access to suitable resources shapes the evolution and maintenance of avian cooperative breeding by influencing whether an individual will have a greater chance of survival and reproduction by dispersing or remaining on a natal territory. Cooperatively-breeding species exhibit altered dispersal according to food availability and habitat quality, but the relationship between resource use, group size, and reproduction in human-al...

Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...

Flood and coastal risk management policy in England increasingly promotes coastal adaptation plans that are co-developed by local communities. Using the village of Happisburgh as a case study, this paper adopts an environmental justice lens to explore local resident and policymaker perspectives of managed realignment that may have a bearing on the implementation of community adaptation plans. Perspectives are elicited through...

Rate of force development (RFD) and impulse (IMP) are important mechanical measures of muscular performance but are relatively unused within the rehabilitation and performance community. Due principally to access to low-cost testing devices and understanding the utility of these measures. The aim of this study therefore was to quantify the reliability of various force–time variables using load-cell technology collected via iso...

Clonidine has various clinical effects mediated by agonism of α 1 - or α 2 -adrenoceptors and the blocking of hyperpolarization-activated-nucleotide-gated pacemaker channels (HCN). It is unknown whether clonidine can also stimulate human cardiac histamine H 2 receptors (hH 2 Rs). We used isolated electrically stimulated left and spontaneously beating right atrial preparations from mice overexpressing the hH 2 R specifically in...

Ergometrine (6a R ,9 R )- N -(( S )-1-hydroxypropan-2-yl)-7-methyl-4,6,6a,7,8,9-hexa-hydro-indolo-[4,3- fg ]chinolin-9-carboxamide or lysergide acid β-ethanolamide or ergonovine) activates several types of serotonin and histamine receptors in the animal heart. We thus examined whether ergometrine can activate human serotonin 5-HT 4 receptors (h5-HT 4 R) and/or human histamine H 2 receptors (hH 2 R) in the heart of transgenic m...

Floral displays often signal the presence of nectar, but nectar may not always be present due to previous visits by nectarivores or temporal changes in nectar availability. But how does the presence of empty flowers impact the preferences of foraging honey bees for the available flowers? We aimed to test if previously rewarding flowers changed the preference relationship between neighboring flowers, and if empty flowers impact...

Adaptation at actively receding coastal areas requires swift and long-term solutions that build resilience for both people and the environment. Nature-based solutions are increasingly being promoted over hard defences, but there is a lack of empirical research on the effectiveness of novel approaches, including those deployed at different scales. Sandscaping, a one-off large-scale deposition of sand (1.8 M m 3 ) on a beach fro...
