“…Temperature has shown an increasing trend in Spain in the last 25 years (de Castro et al 2005), consistent with the Table 3. global increase in mean surface air temperatures detected in the mid-and high-latitudinal continental regions of the northern hemisphere since 1976 (IPCC 2001). This increase has led to important changes in the onset of breeding, clutch size and hatching and fledging success in Mediterranean montane populations of several passerine species (Sanz et al 2003, Potti 2009. Nevertheless, little is known about the influence of temperature on winter bird biology in this region (Senar and Borras 2004).…”

Although energy is a major driver of global patterns of biodiversity and species distribution, the test of species-energy relationships needs further development using fine-grained approaches involving different functional groups of species and small geographical scales of known characteristics (habitat heterogeneity, food availability, direct measures of temperature). We carried out an experiment over a broad range of habitat structure and environmental conditions to disentangle the effects of two different energy measures on the small-scale variation of habitat use in winter: one directly related to food resources (manipulated food availability with artificial feeders), and another related to thermoregulatory costs (night temperature). The spatial variation in abundance of a guild of tree-gleaning birds wintering in montane Mediterranean oakwoods of Central Spain was positively related to both components of energy availability (temperature and food resources), even in these mild Mediterranean montane forest of southern Europe. Spatial variation in consumption of food from artificial feeders was negatively related to spatial variation in temperature. The influence of food availability on bird abundance was mediated by vegetation structure, with a lower influence in maturer oakwoods. This study highlights the important role of the energy-related factors, over habitat structure, in determining winter abundance of the studied tree-gleaning guild.

“…Warming also has significant direct effects on animal phenology by lengthening the period of summer activity and by increasing the number of reproductive cycles and larval size in insects (Stefanescu et al, 2003;Harada et al, 2005;Altermatt, 2010) or by changing the sex ratios in populations of turtles (Tucker et al, 2008). In amphibians and birds, advanced periods of breeding and oviposition in response to warming have been observed (Beebee, 1995;Crick et al, 1997;Schaefer et al, 2006;Potti, 2009). An increase in reproductive success has been observed in reptiles Takeda et al, 2010;Clarke & Zani, 2012) and is frequently accompanied by an advance in the period of oviposition .…”

We review the evidence of how organisms and populations are currently responding to climate change through phenotypic plasticity, genotypic evolution, changes in distribution and, in some cases, local extinction. Organisms alter their gene expression and metabolism to increase the concentrations of several antistress compounds and to change their physiology, phenology, growth and reproduction in response to climate change. Rapid adaptation and microevolution occur at the population level. Together with these phenotypic and genotypic adaptations, the movement of organisms and the turnover of populations can lead to migration toward habitats with better conditions unless hindered by barriers. Both migration and local extinction of populations have occurred. However, many unknowns for all these processes remain. The roles of phenotypic plasticity and genotypic evolution and their possible trade-offs and links with population structure warrant further research. The application of omic techniques to ecological studies will greatly favor this research. It remains poorly understood how climate change will result in asymmetrical responses of species and how it will interact with other increasing global impacts, such as N eutrophication, changes in environmental N : P ratios and species invasion, among many others. The biogeochemical and biophysical feedbacks on climate of all these changes in vegetation are also poorly understood. We here review the evidence of responses to climate change and discuss the perspectives for increasing our knowledge of the interactions between climate change and life.

“…obs.). Early residence in future breeding grounds may promote an early laying date, which is usually related to reproductive success (Norris, 1993), as later clutches tend to be smaller, and earlier-fledged young tend to be heavier and have higher recruitment probabilities (e.g., Verboven and Visser, 1998;Potti, 2009). In this context, the cold wave could have meant a temporal slowdown of this steady increase in abundance, because bird numbers remained unchanged between the cold spell and the prior normal periods (see Table 1).…”

Woodland Mediterranean birds can resist a dry extreme cold wave

The ecological consequences of climate extreme events are still poorly understood, especially those related to cold episodes. Winter cold spells might imperil the energy balance of small passerines, thus compromising their survivorship. Here we analyze how the abundance and habitat use of three tree-gleaning passerine species wintering in a montane oakwood of central Spain at ca. 1,300 m a.s.l. was influenced by the cold wave that hit Europe in February 2012. We monitored temperature, wind and the relative abundance of great tit Parus major, blue tit Cyanistes caeruleus and long-tailed tit Aegithalos caudatus in 15 plots throughout three periods: before, during and after the cold wave. Our results clearly rule out widespread mortality and temporal migration of the studied passerine populations, as the abundance of these species did not diminish during the cold wave. Moreover, the species usually foraging higher in the tree canopy -and thus more exposed to wind-moved to the less windy woodland plots (long-tailed tit) and reduced their foraging height above ground during the cold wave (long-tailed tit and blue tit), probably to mitigate the deleterious effects of wind chill. Therefore, these forest birds were able to cope with a dry cold wave that was statistically extreme in terms of temperature and wind chill, according to the historic climate records of the region. It seems that, at least when foraging substrates are not heavily covered by snow or ice, Mediterranean birds can resist an extreme cold wave [Current Zoology 60 (4): [429][430][431][432][433][434][435][436][437] 2014].
