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...
Low molecular weight ligands govern Cu(II) binding in beerNARA Subscribed
Assessing shortnose sturgeon response to estuarine dredging in the Savannah River using a before-after control-impact (BACI) approachNARA Subscribed
Estuaries are productive ecosystems that support diverse aquatic species and human economies through fisheries, recreation, and navigation. However, coastal development and dredging have altered the ecological processes of estuarine habitats. In the Savannah River estuary, the Savannah Harbor Expansion Project (SHEP) deepened the river’s navigational channel by dredging to amplify vessel commerce. The endangered shortnose stur...
Invertivore fish predation is an overlooked source of carbonate sediment on a turbid coral reefNARA Subscribed
The geomorphic stability of coral reef islands depends on a continued supply of biologically derived sediment from reefs. However, the ecological processes that produce detrital sediment remain poorly resolved. The role of fishes as sediment producers has largely focused on coral sand generated by parrotfishes (Labridae: Scarinae) in clear-water settings, while the contribution of other groups, such as durophagous invertivores...
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...
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...
Atlantic Salmon ( Salmo salar ) populations have experienced significant declines in recent decades. In Canada, conservation efforts are divided into 16 designatable units (DUs) to address unique regional challenges among genetically distinct populations. The Cape Breton Highlands, previously subdivided into two of these DUs, are a particularly understudied region in Atlantic Canada, as a result of limited assessments due to t...
Different Beta‐Diversity Frameworks Reveal Contrasting Roles of Species Abundance Distributions and Spatial AggregationNARA Subscribed
Aim Determining why community composition changes from place‐to‐place (spatial β‐diversity) is central to advancing biodiversity theory and conservation of threatened species. Spatial β‐diversity can occur most simply due to random sampling effects from the larger species‐pool, such as the random placement and distribution of individuals and species. However, ecological processes can also generate intraspecific aggregation cha...
Effective conservation and enforcement strategies for marine turtles depend on understanding population structure, connectivity, and the geographic origins of turtles impacted by threats such as bycatch, overexploitation, and illegal trade. However, mitochondrial DNA (mtDNA) data remain fragmented across studies, with inconsistent sequence lengths, haplotype nomenclature, and metadata standards limiting their application in co...
Dispersion in Porous Media with Porosity GradientsNARA Subscribed
Heterogeneous porous media are found in many engineering and natural processes, either by design to improve the efficiency of the system, or as a consequence of the process itself. Here, we focus on dispersive transport in porous media displaying spatially evolving heterogeneities, characterized by continuous spatial variations of their properties. Using upscaling, we derive the macroscopic transport equations for momentum and...
Main conclusion Almond trees prioritize C to yield rather than stem growth, and their overall lower NSC stores compared to forest trees may have consequences for resilience under environmental variability. Abstract Perennial tree crops store nonstructural carbohydrates (NSCs) as energy reserves that can be used to persist during both predictable periods of reduced activity like dormancy and more unpredictable periods associate...
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...
