Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic SalmonNARA Subscribed
Atlantic salmon ( Salmo salar ) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of salmonids. This study evaluated SAS as a conservation approach by using acoustic telemetr...
Crown-of-thorns starfish (CoTS: Acanthaster spp.) remain one of the foremost causes of coral mortality on coral reefs throughout the Indo West-Pacific, and recurrent population irruptions compound upon other major disturbances, especially climate-induced coral bleaching. Renewed scientific and management interest in CoTS stems from both the initiation of new and renewed population irruptions and sustained degradation of coral...
The ecological effects of high densities of crown-of-thorns starfish (CoTS, Acanthaster spp.) are driven by their cumulative feeding pressure on coral assemblages, making accurate predictions of feeding impacts essential for management. Despite this, a limited understanding of the spatiotemporal dynamics of feeding behaviour, and the environmental and biological drivers underlying them constrains our capacity to predict feedin...
A quantitative comparison of tools for monitoring the abundance of crown-of-thorns starfish and coral coverNARA Subscribed
Effective monitoring of crown-of-thorns starfish (COTS) populations and coral cover is critical for informing management of COTS outbreaks throughout their tropical Indo-Pacific range, including Australia’s Great Barrier Reef. However, existing monitoring tools such as manta tow and cull diver surveys have well-known limitations including accuracy and resource demands. This study evaluates a range of monitoring tools for asses...
The Great Barrier Reef, like most reef ecosystems, is increasingly subject to major acute disturbances, including population irruptions of crown-of-thorns starfish (CoTS) and climate-induced coral bleaching. Given their increasing incidence, acute disturbances are likely to occur simultaneously or successively, though interactive effects of major disturbances are generally unknown. This study explores changes in the feeding be...
Despite extensive research on the western Pacific crown-of-thorns starfish (CoTS; Acanthaster cf. solaris ), especially from Australia’s Great Barrier Reef (GBR), there are persistent knowledge gaps that constrain understanding and management. Given renewed population irruptions of CoTS on the GBR, alongside escalating climate impacts and direct anthropogenic pressures, a quantitative assessment of knowledge gaps was undertake...
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...
Significant declines in Atlantic salmon ( Salmo salar ) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in natural river systems compared to their wild counterparts. This study examined survi...
Crustose coralline algae (CCA) play a central role in coral reef framework consolidation and vertical accretion, yet their contribution to reef-scale calcification remains poorly quantified, particularly on reefs dominated by algal turfs. We examined how CCA calcification rates differed across ten reef sites with varying benthic composition around Lizard Island, Great Barrier Reef, Australia. Using tiles from calcification acc...
Continental Drivers of Population‐Level Intraspecific Trait Variability in Salamanders, Birds, and Small MammalsNARA Subscribed
Aim Intraspecific trait variability (ITV) is a key component of biodiversity because it informs how organisms respond to abiotic and biotic conditions. Understanding how the variability among individuals within a population (population‐level ITV) changes along environmental gradients offers insight into how local processes contribute to broad‐scale biodiversity patterns. Here, we examine how climate and species‐richness intera...
Smallholder households across rural sub-Saharan Africa often rely on goats to support their livelihoods, food security, and financial security, and as a risk mitigation strategy. Across the region, goat health and performance outcomes vary greatly, and it is often difficult to quantify the impact of the animal health-nutrition nexus on livelihood outcomes. Two socio-economic surveys were conducted to this end in Botswana. Firs...
Limited detectability of crown-of-thorns starfish (CoTS) undermines the capacity to survey and manage population irruptions, though few studies have considered the factors that influence detectability. This study explores spatiotemporal variation in detectability of CoTS during emerging population irruptions in four regions of the Northern Great Barrier Reef (GBR), by comparing recorded densities based on the number of CoTS si...
