“…Through experimental warming, Klein et al (2004) found that warming caused large and rapid species loss. Warming may change species geographic ranges as being reported in temperate regions (Iverson and Prasad, 1998;Lenoir et al, 2008 andMoritz et al, 2008) and threaten biodiversity within the TRSR. …”

Changes observed in nine meteorological variables obtained from the Three Rivers Source Region (TRSR) between 1960 and 2009 were investigated using a fitted linear model, Mann-Kendall test, moving t-test, and Morlet wavelet. Analysis of the regionally scaled annual series from 1960 to 2009 showed that minimum (T min ), maximum (T max ), mean (T mean ) air temperature, precipitation (P ), potential evaporation (E p ), and sunshine hours (SH ) increased while relative humidity (RH ) and wind speed (W ) decreased. Trends were significant at a 99% confidence level for air temperature and at a 95% confidence level for E p and W . With the exception of SH , regional scale changes observed in all variables in the past decade (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)) when compared to climate norms (means of all climatic variables) from 1961 to 1990 were consistent with their corresponding linear trends from 1960 to 2009. T max , T mean , and drought index (DI ) exhibited one climate jump, T min and RH two, and SH , E p , and W three at a significance level of α = 0.05. On a regional scale, the period from 1986 to 1997 experienced a warmer, drier climate due to higher than average air temperatures, lower P , and higher DI compared to means from 1960 to 2009. The majority of meteorological variables of the TRSR experienced significant (α = 0.05) short periodical cycling between 2 and 5 years. In terms of spatial distribution, seven out of 12 meteorological stations underwent warmer and wetter periods from 1960 to 2009, whereas the other five situated in the southeastern section of the TRSR underwent warmer, drier periods.

“…Climate change may increase the extinction risk of already endangered species already threatened by small populations, low genetic diversity, habitat specialization or a limited geographic range (Moritz et al, 2008;Fordham et al, 2013). Most endangered species are specialists confined to restricted habitats, less physiologically tolerant to environmental change and less able to migrate/disperse to track climate change (Svenning and Skov, 2004;Maclean and Wilson, 2011).…”

a b s t r a c tIt is increasingly recognized that biotic interactions could play a significant role in species distribution modelling. To assess the conservation effectiveness of the giant panda (Ailuropoda melanoleuca) reserves in a changing climate, we combined both biotic variables (food availability) and abiotic (climatic and geographic) to project the potential changes of distribution and quality of giant panda habitats using the most recent IPCC-CMIP5 climate scenarios. Our results suggested that climate change would adversely affect giant pandas through habitat degradation, in that: (1) 52.9-71.3% of the current habitats could be lost; (2) the giant panda habitats could become more fragmented and isolated; and (3) both the quantity and quality of habitats in the current giant panda reserves could substantially contract, and approximately 20% of the reserves could lose all habitat representations in this century. Additionally, we found that climate change would make it increasingly necessary to translocate small populations of pandas from the southwestern to the northwestern part of the current distribution range to ensure population viability. Our results suggest the need for immediate change in current conservation policies and formulating adaptation plans for giant panda conservation in a changing climate.

Lowland biotic attrition revisited: body size and variation among climate change ‘winners’ and ‘losers’

et al. 2017

The responses of lowland tropical communities to climate change will critically influence global biodiversity but remain poorly understood. If species in these systems are unable to tolerate warming, the communities-currently the most diverse on Earth-may become depauperate ('biotic attrition'). In response to temperature changes, animals can adjust their distribution in space or their activity in time, but these two components of the niche are seldom considered together. We assessed the spatio-temporal niches of rainforest mammal species in Borneo across gradients in elevation and temperature. Most species are not predicted to experience changes in spatio-temporal niche availability, even under pessimistic warming scenarios. Responses to temperature are not predictable by phylogeny but do appear to be trait-based, being much more variable in smaller-bodied taxa. General circulation models and weather station data suggest unprecedentedly high midday temperatures later in the century; predicted responses to this warming among small-bodied species range from 9% losses to 6% gains in spatio-temporal niche availability, while larger species have close to 0% predicted change. Body mass may therefore be a key ecological trait influencing the identity of climate change winners and losers. Mammal species composition will probably change in some areas as temperatures rise, but full-scale biotic attrition this century appears unlikely.
