“…Because of their smaller range, changes in climate such as temperature could affect more or all of their year-round range. If they cannot adapt quickly enough, they could face dramatic range contraction, as has been observed in several sedentary species (Moritz et al, 2008;Gibson et al, 2010). Climate change could also have indirect effects on interactions between altitudinal migrants and residents.…”

Animal migration has been the subject of intensive research for more than a century, but most research has focused on long-distance rather than short-distance migration. Altitudinal migration is a form of short-distance migration in which individuals perform seasonal elevational movements. Despite its geographic and taxonomic ubiquity, there is relatively little information about the intrinsic and extrinsic factors that influence altitudinal migratory behaviour. Without this information, it is difficult to predict how rapid environmental changes will affect population viability of altitudinal migrants. To synthesize current knowledge, we compiled literature on altitudinal migration for all studied taxa, and identified the leading hypotheses explaining this behaviour. Studies of animal altitudinal migration cover many taxonomic lineages, with birds being the most commonly studied group. Altitudinal migration occurs in all continents except for Antarctica, but about a third of the literature focused on altitudinal migration in North America. Most research suggests that food and weather are the primary extrinsic drivers of altitudinal migration. In addition, substantial individual-level variation in migratory propensity exists. Individual characteristics that are associated with sex, dominance rank, and body size explain much of the variation in migratory propensity in partially migratory populations, but individual-level correlates are poorly known for most taxa. More research is needed to quantify the effects of habitat loss, habitat fragmentation, and climate change on altitudinal migrants. Demographic studies of individually marked populations would be particularly valuable for advancing knowledge of the cascading effects of environmental change on migratory propensity, movement patterns, and population viability. We conclude our review with recommendations for study designs and modelling approaches that could be used to narrow existing knowledge gaps, which currently hinder effective conservation of altitudinal migratory species.

“…The degree of range contraction has also been predicted to increase with escalating severity of climate change scenarios. Under the most severe changes, Gibson et al (2010) predicted that the quoakka (Setonix brachyurus) would essentially lose all of its range.…”

Global climate change has been suggested to cause decrease of distribution area of many species. However, this has not been tested for East Asian inland coldwater fish. Chinese minnow (Rhynchocypris oxycephalus) is a small typical coldwater fish, which is endemic to East Asia and generally inhabits stream headwaters. Due to its occurrence in temperate south China, there is growing concern about its future fate in the face of global warming. In this study, we employed maximum entropy approach to analyze how distribution of this species would be impacted by future climate change. We collected data of 310 independent distribution points and 20 environmental variables, and conducted modeling under three general circulation models assuming two gas emission scenarios for 2020s, 2050s, and 2080s. The results showed that the Min temperature of coldest month was the most important climatic variable for potential distribution of the Chinese minnow. Modeling predicted geographical distribution of the Chinese minnow would shrink over time and become much more limited in all the situations especially in South-eastern China, and there would be little suitable habitat left in this region by 2080s. Our results confirm that climate change clearly poses a severe threat to the Chinese minnow, and we suggest that conservation efforts should focus on lower temperature areas within the current range, because these areas will remain relatively cool and may be still suitable for the Chinese minnow even under the most drastic climate change scenarios.

For species that are increasingly threatened by the combined impacts of habitat loss and climate change, the identification of priority regions for conservation planning efforts is urgently required. In the case of specialist folivores, consideration of the effects of climate change on the distributions of their essential food resources should be a key component of conservation planning. The koala (Phascolarctos cinereus) was listed in 2012 as vulnerable under Australian Commonwealth Government law. Here, we incorporate species distribution models for the koala, an arboreal marsupial, and its specialized food resources, to identify broad-scale priority conservation regions. We demonstrate a spatial prioritization approach that informs conservation planning and that links the shifting distribution of this declining species and its critical food resources under climate change. We find that the inclusion of food plants affected the identification of priority regions for conserving koalas, and that priority regions for the conservation of this species are predicted to shift considerably, often outside the current range of this species, posing additional challenges for its conservation.
