“…Such variation has led to a mismatch in the timing of previously synchronous life-history events in interacting species [11 -13]. As a consequence, these changes in temporal overlap and resulting effects on predator -prey and competition dynamics may have important implications for populations or community structure [14].…”

Climate change correlates with rapid delays and advancements in reproductive timing in an amphibian community

Climate change has had a significant impact globally on the timing of ecological events such as reproduction and migration in many species. Here, we examined the phenology of reproductive migrations in 10 amphibian species at a wetland in South Carolina, USA using a 30 year dataset. We show for the first time that two autumn-breeding amphibians are breeding increasingly later in recent years, coincident with an estimated 1.28C increase in local overnight air temperatures during the September through February pre-breeding and breeding periods. Additionally, two winter-breeding species in the same community are breeding increasingly earlier. Four of the 10 species studied have shifted their reproductive timing an estimated 15.3 to 76.4 days in the past 30 years. This has resulted in rates of phenological change that range from 5.9 to 37.2 days per decade, providing examples of some of the greatest rates of changing phenology in ecological events reported to date. Owing to the opposing direction of the shifts in reproductive timing, our results suggest an alteration in the degree of temporal niche overlap experienced by amphibian larvae in this community. Reproductive timing can drive community dynamics in larval amphibians and our results identify an important pathway by which climate change may affect amphibian communities.

“…Great crested newts are dispersal-limited, both in distance and sensitivity to land cover upon dispersal (Arntzen and Wallis 1991;Arntzen and Teunis 1993;Jehle and Arntzen 2000;Langton et al 2001;Griffiths et al 2010), and are sensitive to climate change (Reading 2007;Blaustein et al 2010;Griffiths et al 2010). As amphibians depend on both terrestrial and aquatic habitat, they are indicators for species that depend on wide array of habitat types.…”

“…The great crested newt was selected as a model species, because (i) it is a characteristic species for the Baakse Beek area; (ii) it is a species of conservation concern in the Netherlands, listed as 'vulnerable' on the national red list, and a species for which the Netherlands has international responsibility (Habitats Directive, listed at Annex II and Annex IV); (iii) great crested newts depend on both terrestrial and aquatic habitat throughout their life span, and are considered sensitive to landscape configuration upon dispersal (Jehle and Arntzen 2000); and (iv) amphibians are considered sensitive to climate change as they are sensitive to environmental stochasticity and depend on small waters that are vulnerable to droughts (Blaustein et al 2010). Studying the effects of climate change on the viability of a species like the great crested newt, and the effectiveness of landscape adaptation measures, could therefore bring broader understanding of the conservation needs of a larger group of terrestrial species with limited dispersal capacity.…”

Is green infrastructure an effective climate adaptation strategy for conserving biodiversity? A case study with the great crested newt

et al. 2015

Context Increasing the amount of green infrastructure, defined as small-scale natural landscape elements, has been named as a climate adaptation measure for biodiversity. While green infrastructure strengthened ecological networks in some studies, it is not known whether this effect also holds under climate change, and how it compares to other landscape adaptation options. ObjectivesWe assessed landscape adaptation options under scenarios of climate change for a dispersallimited and climate-sensitive species: great crested newt, Triturus cristatus. Methods A spatially-explicit modelling framework was used to simulate newt metapopulation dynamics in a case study area in the Netherlands, under alternative spatial configurations of 500 ha to-berestored habitat. The framework incorporated weather-related effects on newt recruitment, following current and changing climate conditions. Results Mild climate change resulted in slightly higher metapopulation viability, while more severe climate change (i.e. more frequent mild winters and summer droughts) had detrimental effects on metapopulation viability. The modelling framework revealed interactions between climate and landscape configuration on newt viability. Restoration of ponds and terrestrial habitat may reduce the negative effects of climate change, but only when certain spatial requirements (habitat density, connectivity) as well as abiotic requirements (high ground water level) are met. Conclusions Landscape scenarios where habitat was added in the form of green infrastructure were not able to meet these multiple conditions, as was the case for a scenario that enlarged core areas. The approach allowed a deduction of landscape design rules that incorporated both spatial and abiotic requirements resulting in more effective climate adaptation options.Electronic supplementary material The online version of this article

This study was executed to know the effect of three differently controlled temperature conditions on Huanren brown frog (Rana huanrensis)'s growth in 2013. We've collected nine Huanren brown frog egg's sacs on Mt. Surak (37°40'55.86"N, 127°05'19.99"E) in Seoul. We put those nine egg sacs in the controlled growth chambers under low temperature (LT, 5 ± 2℃), medium temperature (MT, 10 ± 2℃), and high temperature (HT, 13 ± 2℃) conditions with three egg sacs, respectively. We measured the eggs' hatching rate, their hatching periods, and the size of the hatched individuals. The hatching rate was higher in MT (95.6%) and the rates of the other treatments were relatively lower but very similar such as LT (82.2%) and HT (82.6%). The three hatching periods were 10 days at HT, 14 days at MT and 23 days at LT. The body sizes of the hatched individuals were biggest at MT (7.62 ± 0.11㎜), smallest at LT (6.82 ± 0.10㎜) and medium at HT (7.19 ± 0.15㎜) (P-value ≤0.0001). From our results, we found that the various water temperatures could be very effective to Huanren brown frog eggs' hatch and growth including their body sizes. We suggest if we study more about the growth of Huanren brown adult frogs under similar temperature 1) †
