“…Studies in Fiji suggest that maintaining at least 50% of catchment forest cover can retain most riverine fish species (Jenkins et al., ; Jupiter et al., ). Furthermore, forest protection can benefit downstream coral reef condition by prevention of terrestrial runoff and sedimentation (Klein, Jupiter, Watts, & Possingham, ). Thus, a comprehensive forest protection plan is critical to secure river, terrestrial and marine biodiversity and ecosystem function.…”

Anthropogenic disturbances particularly affect biodiversity in sensitive freshwater ecosystems by causing species loss. Thus, measuring the response of species to multiple disturbances is a key issue for conservation and environmental management. As it is not practical to assess the response of every species in a community, we compared the performance of trait and taxonomic-based groupings of species for their abilities to predict species loss in a threatened freshwater fish assemblage. Specifically, we examined responses of a Fijian freshwater fish assemblage to deforestation, placement of anthropogenic barriers (overhanging culverts) and the presence of introduced cichlids. Species grouped by traits showed more consistent responses to disturbances than taxonomic groups. In particular, species belonging to trait groups that were estuary associated favoured medium-to-hard substrate, while feeding specialists were highly likely to be absent in catchments with high deforestation and overhanging culverts. The presence of introduced cichlids (Oreochromis mossambicus and O. niloticus) had a smaller effect than deforestation and barriers, but was negatively associated with species richness of diadromous species with climbing ability and positively associated with presences of some piscivores. The trait groups also revealed that detritivores, species favouring soft substrate, and those with a broad dietary range were less sensitive to anthropogenic disturbances. Our study indicates that using traits to predict species loss from disturbed environments can aid in detecting the responses of rare species to disturbance. In addition, we provided a method to estimate the consistency of species’ responses to disturbance. This study may ultimately help managers identify the most effective actions for conserving sensitive species that are seldom recorded in surveys

“…Integrated planning exercises allocating actions in multiple realms are less common and generally restricted to two realms, including (d) prioritising terrestrial and marine conservation areas while minimising land-based threats (6: e.g. Klein et al, 2010;Klein et al, 2014) or (e) simultaneously targeting terrestrial and freshwater assets (7: e.g. Amis et al, 2009;Noss et al, 2002).…”

“…While there have been important advances in theoretical approaches to cross-realm planning (Adams et al, 2014a;Álvarez-Romero et al, 2011), practical advice on their application for decision-makers is generally lacking (but see Klein et al, 2014 for an example of cross-realm planning influencing on-ground actions). Importantly, existing conceptual and operational frameworks are generally developed in academic settings without the participation of decision-makers responsible for implementing plans.…”

Conserving migratory species under human impacts and climate change

Migratory species use multiple habitats types and ecosystems to complete their life cycles, which exposes them to multiple human-caused stressors along their migratory routes. Overexploitation, habitat degradation, invasive species and connectivity loss have contributed to the decrease of migratory fishes globally in particular diadromous fishes that migrate between marine and freshwater systems. Therefore, understanding the joint impacts from anthropogenic disturbances and climate change on different habitats (e.g., both feeding and spawning grounds) and habitat connectivity (e.g., migration routes) is important for conserving migratory fish.Management will be most effective when management scales match ecological scales. This is particularly important for conserving migratory species, because of the requirement of multiple connected habitats that may cross local management boundaries. The main goals of this Ph.D. thesis are to quantify the impacts of multiple stressors on migratory fish species and prioritize management actions for conserving populations (chapters 2 & 3), species (chapter 4), and communities (chapter 5).A central challenge for managing diadromous fishes (species that migrate between freshwater and saltwater ecosystems) is to quantify increases in population persistence from actions that improve connectivity or reduce fishing mortality. In chapter 2, I used a population dynamic model and fish movement data to predict the interactive impacts of fishing pressure and connectivity loss by human modification of river flows on Australian bass Percalates novemaculeata. Then, in chapter 3, the monetary cost of management actions which included seasonal closures and restoring connectivity, were included in the model to find the most cost-effective way to conserve this fish population. The results reveal that the cost-effectiveness of management actions may vary with river flow and fishing pressure before implementing management actions, and implementation times. The spatiotemporal dynamics of how fish species and key resource users (i.e., anglers) respond to management actions can influence the effectiveness of management strategies. Flexible management plans and increased cooperation between water and fishery managers can be used to achieve the most effective balance between conserving migratory fish populations and minimising cost.Migratory species are particularly vulnerable to climate change as they occupy different ecosystems, as well as transitional habitat which are all impacted by climate change differently.Anthropogenic barriers can further reduce the ability of species to respond to a shifting climate. In ii chapter 4, I assessed the impact of climate change on the distribution of a migratory fish species, Australian grayling Prototroctes maraena, and how it affected priorities for restoring connectivity. I found climate change moves at different rates in marine and freshwater systems, decoupling the habitats used by grayling. In addition, the changing spatial distribution of suitable ...
