“…Study periods of several years also enable to investigate if and how populations recover. Other studies merely assessed the period immediately following the extreme weather event (Mouthon and Daufresne 2006;Piha et al 2007). Therefore, they only pointed towards declining populations and changes in community composition, but did not give any indications about the reversibility of these effects.…”

“…Because climate change models predict an increased occurrence of extreme weather events during the second half of the twenty-first century (Trenberth et al 2007;Meehl and Tebaldi 2004), it is important to know how species react to extreme climatic events (McLaughlin et al 2002). Up till now, most research on the effects of climate change has primarily focused on the consequences of increased average temperatures, whereas studies on the effects of extreme events are scarce (Opdam and Wascher 2004, but see Mouthon and Daufresne 2006;Piha et al 2007;Rouault et al 2006;Jentsch et al 2007). Research on the combined effects of these extreme events and habitat fragmentation are even more scarce (Opdam and Wascher 2004), although modelling studies have shown the combination of habitat loss and climate change to be a disastrous mixture (Travis 2003;Thomas et al 2004).…”

Synergistic effects of an extreme weather event and habitat fragmentation on a specialised insect herbivore

et al. 2008

Habitat fragmentation is considered to be one of the main causes of population decline and species extinction worldwide. Furthermore, habitat fragmentation can decrease the ability of populations to resist and to recover from environmental disturbances such as extreme weather events, which are expected to occur at an increasing rate as a result of climate change. In this study, we investigated how calcareous grassland fragmentation affected the impact of the climatically extreme summer of 2003 on egg deposition rates, population size variation and survival of the blue butterfly Cupido minimus, a specialist herbivore of Anthyllis vulneraria. Immediately after the 2003 summer heat wave, populations of the host plant declined in size; this was paralleled with decreases in population size of the herbivore and altered egg deposition rates. In 2006 at the end of the monitoring period, however, most A. vulneraria populations had recovered and only one population went extinct. In contrast, several butterfly populations had gone extinct between 2003 and 2006. Extinction probability was significantly related to initial population size, with small populations having a higher risk of extinction than large populations. These results support the prediction that species of higher trophic levels are more susceptible to extinction due to habitat fragmentation and severe disturbances.

“…In Central America, amphibian declines have been connected with climate-driven reductions in leaf-litter microhabitat (Whitfield et al 2007), while in Europe, amphibian persistence during a climate extreme was related to landscape heterogeneity (Piha et al 2007). Understanding the spatial scale at which climate-associated threats affect amphibians is crucial for developing and effectively implementing management responses.…”

Decline of an endangered amphibian during an extreme climatic event

Abstract. Climate change is a poorly understood, emerging threat to many amphibian species. One of the ways climate change is likely to affect amphibians is through increased recruitment failure associated with more frequent climatic extremes. To understand the risk posed by this threat, we combined 13 years of annual monitoring and multi-scaled habitat modelling at the site (n ¼ 60), pool (n ¼ 105) and nest (n ¼ 170) levels to investigate the decline of the endangered northern corroboree frog (Pseudophryne pengilleyi ), during the most severe drought on record in southern Australia. We documented the local extinction of 42% of P. pengilleyi breeding sites during the climatic extreme. Using logistic regression we investigated habitat variables associated with extinction sites. We found that locally extinct sites now resemble historically absent sites, with fewer pools, less water, and drying-related tree invasion. Extended periods of limited water availability at extinction sites is likely to have restricted breeding, contributing to localised extinctions. Habitat variables recorded at the pool and nest level did not significantly influence P. pengilleyi presence/absence, indicating that site level wetness had an overriding effect. We anticipate that increasing climate variability is likely to disproportionately threaten seasonal pool-breeding amphibian species, exacerbating the global amphibian biodiversity crisis. However, our work with P. pengilleyi suggests there are a range of simple habitat manipulations that could help to ameliorate the impacts.

“…Several authors have suggested that landscape heterogeneity confers stability to landscapes and may buffer populations against environmental change, relative to organisms in landscapes that are more homogeneous (Benton et al 2003;Dover and Settele 2009;Forman 1997;Luoto and Heikkinen 2008). Support for this hypothesis has been demonstrated experimentally for crickets (Kindvall 1996), amphibians (Piha et al 2007), and butterflies (Oliver et al 2010). Avian populations in parts of the Western US have contended with natural heterogeneity for thousands of years and may be less affected by fragmentation processes, such as exurban development, than avian populations of the relatively more homogeneous landscapes of the pre-European-settlement Eastern US (George and Dobkin 2002;Tewksbury et al 1998).…”

We examined the impacts of exurban development on bird communities in Essex County, New York and Madison County, Montana by comparing differences in abundance of songbirds between subdivisions and control sites in both regions. We hypothesized that impacts to bird communities would be greater in the relatively homogeneous, closed canopy Adirondack forest of northern New York State than they would be in the more naturally heterogeneous grasslands interspersed with trees and shrubs of the Greater Yellowstone Ecosystem. We examined birds in five functional groups expected to be responsive to exurban development, and determined relative abundance within subdivisions and control sites across these two distinct regions. We found little support for our hypothesis. For birds in the area-sensitive, low nesting, and Neotropical migrant functional groups, relative abundance was lower in subdivisions in the Adirondacks and in Madison County, while relative abundance of edge specialists was greater in subdivisions in both regions. The direction and magnitude of change in the avian communities between subdivisions and controls was similar in both regions for all guilds except microhabitat specialists. These similarities across diverse ecosystems suggest that the ecological context of the encompassing region may be less important than other elements in shaping avian communities in exurban systems. This finding suggests that humans and their specific behaviors and activities in exurban areas may be underappreciated but potentially important drivers of change in these regions.
