Genetic diversity underpins the ability of populations to persist and adapt environmental changes. Substantial empirical data show that genetic rapidly deteriorates in small isolated due drift, leading reduction adaptive potential fitness increase inbreeding. Assisted gene flow (e.g. via translocations) can reverse these trends, but lack on loss fear impairing population "uniqueness" often prevents managers from acting. Here, we use riverscape analyses simulations explore consequences...
Seagrasses are important marine ecosystems situated throughout the world's coastlines. They facing declines around world due to global and local threats such as rising ocean temperatures, coastal development pollution from sewage outfalls agriculture. Efforts have been made reduce seagrass loss through reducing regional stressors, active restoration. Seagrass restoration is rapidly maturing but improved practices needed enhance success of future programs. Major gaps in knowledge remain,...
High throughput DNA sequencing of bulk invertebrate samples or metabarcoding is becoming increasingly used to provide profiles biological communities for environmental monitoring. As becomes more widely applied, new reference barcodes linked individual specimens identified by taxonomists are needed. This can be achieved through using extraction methods that not only suitable but also building barcode libraries.In this study, we test the suitability a rapid non-destructive method freshwater...
Summary Urbanization alters the environmental characteristics of aquatic ecosystems, often reducing availability and quality habitats for animals. Improving condition urban waterbodies is increasingly important, but management activities could have unintended outcomes that increase extinction risk A mismatch can exist between human perceptions habitat quality, what represents functional This lead to animals not responding activities, if presumed high‐quality are unsuitable. More seriously,...
Habitat loss and fragmentation often result in small, isolated populations vulnerable to environmental disturbance of genetic diversity. Low diversity can increase extinction risk small by elevating inbreeding depression, reducing adaptive potential. Due their linear nature extensive use humans, freshwater ecosystems are especially habitat fragmentation. Although the effects on structure have been extensively studied migratory fishes, they less understood low-mobility species. We estimated...
Environmental DNA (eDNA) sampling can provide accurate, cost-effective, landscape-level data on species distributions. Previous studies have compared the sensitivity of eDNA to traditional methods for single species, but similar comparative multispecies metabarcoding are rare. Using hierarchical site occupancy detection models, we examined whether key choices associated with (primer selection, low-abundance read filtering and number positive water samples used classify a as present at site)...
Abstract Genetic markers are widely used to define and manage populations of threatened species based on the notion that with unique lineages mt DNA well‐differentiated nuclear marker frequencies should be treated separately. However, a danger this approach is genetic uniqueness might emphasized at cost diversity, which essential for adaptation potentially boosted by mixing geographically separate populations. Here, we re‐explore issue defining management units, focussing detailed study G...
Climate change and urbanization threaten streams the biodiversity that rely upon them worldwide. Emissions of greenhouse gases are causing air sea surface temperatures to increase, even small areas degrading stream biodiversity, water quality hydrology. However, empirical evidence how increasing together affect over time their relative influence on is limited. This study quantifies changes in a region South-East Australia with an urban-agricultural-forest landcover gradient where have been...
Urban stormwater management is complex with diverse institutional responsibilities, imperfect regulation, and limited, often unclear accountabilities. Improving practices in that context requires strong leadership, long-term commitment, lasting interorganizational relationships founded on trust. We summarize events steered Melbourne's waterway authority to support a catchment-scale experiment markedly different from applications or research approaches it had previously attempted. highlight...
Quantifying pollutant removal by stormwater wetlands requires intensive sampling which is cost-prohibitive for authorities responsible a large number of wetlands. Wetland managers require simple indicators that provide practical means estimating performance and prioritising maintenance works across their asset base. We therefore aimed to develop vegetation cover metrics derived from monitoring water level, as likely nutrient Over two-year period, we measured levels at 17 used both predict...
Planning for future urban development and water infrastructure is uncertain due to changing human activities climate. To quantify these changes, we need adaptable fast models that can reliably explore scenarios without requiring extensive data inputs. While such have been recently considered development, they are lacking stormwater pollution assessment. This work proposes a novel Future Urban Stormwater Simulation (FUSS) model, utilizing previously developed planning algorithm (UrbanBEATS)...
