“…We calculated the magnitude of the 1980-2005 trend in average maximum and minimum temperatures of the breeding season (TMAXTrend and TMINTrend, respectively; expressed in°C/25 years) and in total monthly precipitation of the breeding season (PRECIPTrend; expressed in mm/25 years) using ordinary least squares regression. We chose these climatic variables because temperature and precipitation of the breeding season have been shown to be significant predictors of avian occurrence and abundance (Jiguet et al, 2010;McDonald et al, 2012).…”

Aim Biodiversity patterns and the mechanisms driving these patterns are inherently scale dependent. Studies investigating biodiversity scaling have focused mostly on evaluating community turnover without taking into consideration its underlying processes of local extinction (hereafter, extinction) and colonization. Our goal was to evaluate the spatial scaling of change in avian assemblages through time and identify environmental drivers of community‐wide dynamics across a range of spatial scales, with a focus on extinction and colonization. Location New York State. Methods We analysed community dissimilarity, temporal turnover, extinction and colonization as measures of temporal change in avian communities at five spatial resolutions (5 × 5, 10 × 10, 20 × 20, 40 × 40 and 80 km × 80 km). We evaluated the relationships between community change and change in climatic conditions, landscape fragmentation and elevation at each spatial grain using Bayesian spatially varying intercept models. Results We found that the decline in colonization with increasing spatial scale was less steep than the decline in community dissimilarity, temporal turnover or extinction. We also found that the importance of environmental drivers to community change was dependent on both scale and metric, though we did not find optimal spatial scales at which either landscape or climatic processes consistently drove patterns of community change. Landscape characteristics were the most important correlate of extinction at all spatial scales, while colonization was not predicted well by any of the environmental factors. Main conclusions The slower decline in colonization across spatial grains is probably a consequence of the high mobility and dispersal abilities of birds. We further conclude that the two processes underlying community change – extinction and colonization – are driven by different factors. Landscape characteristics strongly affect the rates of extinctions in avian communities. On the contrary, patterns of colonization are likely to be a result of intrinsic characteristics of birds – specifically, high dispersal ability – that allow them to colonize new sites, regardless of the environmental context.

“…With the unprecedented current rate of global climate and land‐use change, many populations undergo dramatic range contractions or expansions (McCarty ; Bohning‐Gaese & Lemoine ; McDonald et al . ), increasing the need for up‐to‐date information on population structures and distributions and understanding underlying drivers, including potential dispersal between populations. Assessments of population delineation have traditionally been based on direct methods such as recoveries of dead ringed birds, observations of marked individuals, tracking of birds marked with transmitters and, more recently, by indirect and direct genetic methods.…”

“…Hence, in cases where a species has been divided into more than one population, knowledge of delineation of populations, rate of exchange and gene flow between populations is a fundamental prerequisite for population conservation, harvest management, designation of networks of key sites and disease transmission risk assessments. With the unprecedented current rate of global climate and land-use change, many populations undergo dramatic range contractions or expansions (McCarty 2001;Bohning-Gaese & Lemoine 2004;McDonald et al 2012), increasing the need for up-todate information on population structures and distributions and understanding underlying drivers, including potential dispersal between populations.

Summary1. Conservation and management of migratory waterbirds use flyway populations as the basic unit, and knowledge of the delineation, rate of exchange and gene flow between populations is fundamental. However, for the majority of global flyway populations, information is too fragmentary to address connectivity between populations and, hence, insufficient to inform management. 2. We investigated the demographic connectivity between the eastern (breeding in Svalbard and wintering in Denmark, the Netherlands and Belgium) and western (breeding in Greenland or Iceland and wintering in Britain) flyway populations of pink-footed geese Anser brachyrhynchus based on resightings of marked geese from both populations. Previous genetic analyses suggested a modest gene flow between the two populations. 3. Capture-recapture analysis conservatively estimated that mean annual movement probabilities were low (eastern to western population: 0Á071%, 95% CI = 0Á033-0Á15%; western to eastern: 0Á076%, 95% CI = 0Á031-0Á18%). Movement probability from eastern to western flyway populations increased in years with high snow cover in the southernmost winter range in Belgium. Life histories of exchanged individuals from eastern to western (32 different individuals during 1988-2010) revealed that the majority entered Britain via Belgium and the Netherlands during winter; some returned to the eastern population via Belgium and/or the Netherlands, others moved northwards in Britain during the spring and appear to have migrated directly from Britain (western population) to Norway (eastern population). None of the birds from the eastern population emigrated permanently, but some individuals turned up in Britain in consecutive years. Out of nine individuals switching from western to eastern flyway populations, three returned to Britain; the others were not subsequently resighted. An alternative winter strategy and spring flyway over Britain to Norway is suggested, used by hundreds to thousands of eastern birds, particularly following severe winters. Thus, the two populations currently appear to be demographically closed; low genetic connectivity probably reflects dispersal over longer time. 4. Synthesis and applications. Current initiatives to internationally manage the eastern population of pink-footed geese do not need to consider net immigration in predictive harvest models. For waterbirds in general, a targeted approach to evaluate connectivity, using classic marking studies in combination with molecular methods and focussed sampling on breeding grounds, is recommended to better underpin management decisions at population levels.

“…To fill this research gap, we used data from the New York State Breeding Bird Atlas to investigate the responses of forest and grassland birds to over 20 years of climate change across a range of suitable land cover. We focus on relationships with changing temperature and precipitation, as the main climatic factors driving distributions, abundance, and breeding success in bird populations (Moss et al 2001;Jiguet et al 2010;McDonald et al 2012). Specifically, we seek to evaluate three interrelated questions: (i) do distributional responses to changing climatic conditions differ for forest versus grassland dependent birds?…”

Synergistic effects of climate and land cover: grassland birds are more vulnerable to climate change

Context Climate change is not occurring over a homogeneous landscape and the quantity and quality of available land cover will likely affect the way species respond to climate change. The influence of land cover on species' responses to climate change, however, is likely to differ depending on habitat type and composition.
