“…alpine and freshwater communities), it may be possible to minimize interactions through the protection or installation of climate refuges or buffer strips (Mantyka-Pringle et al, 2014;Shoo et al, 2011) or by manipulating vegetation structure, composition, or disturbance regimes (Hansen et al, 2001). Other adaptation strategies may include translocating vulnerable species to novel habitats (Schwartz and Martin, 2013), altering fire regimes, or mitigating other threats such as invasive species, habitat fragmentation and pollution. Policy-makers and planners should therefore optimize management actions as well as protected area placement in areas where biodiversity and endangered species are most at risk.…”

a b s t r a c tClimate change and land-cover change will have major impacts on biodiversity persistence worldwide. These two stressors are likely to interact, but how climate change will mediate the effects of land-cover change remains poorly understood. Here we use an empirically-derived model of the interaction between habitat loss and climate to predict the implications of this for biodiversity loss and conservation priorities at a global scale. Risk analysis was used to estimate the risk of biodiversity loss due to alternative future land-cover change scenarios and to quantify how climate change mediates this risk. We demonstrate that the interaction of climate change with land-cover change could increase the impact of land-cover change on birds and mammals by up to 43% and 24% respectively and alter the spatial distribution of threats. Additionally, we show that the ranking of global biodiversity hotspots by threat depends critically on the interaction between climate change and habitat loss. Our study suggests that the investment of conservation resources will likely change once the interaction between climate change and land-cover change is taken into account. We argue that global conservation efforts must take this into account if we are to develop cost-effective conservation policies and strategies under global change.

“…The translocation of species is an increasingly used conservation strategy to manage and restore populations of threatened fish species (Olden, Kennard, Lawler, & Poff, 2011;Schwartz & Martin, 2013). Translocations may be to habitats previously occupied or that are novel; however, in both cases, a critical step is evaluating the outcomes of translocated individuals to evaluate the likelihood of long-term population persistence.…”

Translocation of individuals is a widely used tool in the conservation of threatened species. The movement behaviours of translocated individuals in their new environment are a key factor that can influence translocation success (i.e. survival and reproduction). In this study, eel-tailed catfish (Tandanus tandanus) and Murray cod (Maccullochella peelii) movements were monitored using fine-scale acoustic telemetry over a 5-month period in two lowland rivers in eastern Australia. Fine-scale movement and habitat selection were compared among translocated lacustrine and resident riverine T. tandanus and between species. We found no difference in finescale movement behaviours between translocated and resident T. tandanus; however, there was some variation in movement response to environmental variation between species. In contrast, habitat selection varied not only between the two species, but also between resident and translocated T. tandanus individuals. Notably, activity was significantly lower in the first day after release compared to the remainder of the study period. Although T. tandanus translocated from a reservoir had never experienced the environmental fluctuations of a riverine system, individuals still responded in the same way as resident riverine fish, suggesting an innate behavioural response. However, this was not the case for habitat selection, where translocated individuals preferred habitats more common in their source population's lacustrine environment. The findings of this study are important in guiding future conservation efforts involving the translocation of wild-caught fish, primarily the importance of the suitable habitat at the release site to ensure the success and persistence of translocated populations.

“…We can, instead, manipulate the response of vulnerable native taxa to render them more resilient to the invader's arrival. For example, inoculating African wild dogs against distemper can protect them even if we cannot prevent the disease from spreading [2], and translocating organisms may buffer climate-change impacts on the species involved [3].…”

Ecological immunization: in situ training of free-ranging predatory lizards reduces their vulnerability to invasive toxic prey

In Australia, large native predators are fatally poisoned when they ingest invasive cane toads (Rhinella marina). As a result, the spread of cane toads has caused catastrophic population declines in these predators. Immediately prior to the arrival of toads at a floodplain in the Kimberley region, we induced conditioned taste aversion in free-ranging varanid lizards (Varanus panoptes), by offering them small cane toads. By the end of the 18-month study, only one of 31 untrained lizards had survived longer than 110 days, compared to more than half (nine of 16) of trained lizards; the maximum known survival of a trained lizard in the presence of toads was 482 days. In situ aversion training (releasing small toads in advance of the main invasion front) offers a logistically simple and feasible way to buffer the impact of invasive toads on apex predators.
