“…However, to accurately evaluate how much this change resulted from anthropogenic impact on the environment, rather than reflecting natural processes, it would be desirable to have baseline data of temporal changes in ecological communities against which anthropogenic impact can be measured [36], [37]. Unfortunately, such data is meagre since community oriented long-term research on breeding birds has been conducted primarily on local forests (for example, [38]–[43]). Even if communities were locally undisturbed, they would be affected by large scale consequences of human activities, for example, acid rain, nitrogen deposition or global temperature change.…”

Human land use and climate change are regarded as the main driving forces of present-day and future species extinction. They may potentially lead to a profound reorganisation of the composition and structure of natural communities throughout the world. However, studies that explicitly investigate both forms of impact—land use and climate change—are uncommon. Here, we quantify community change of Dutch breeding bird communities over the past 25 years using time lag analysis. We evaluate the chronological sequence of the community temperature index (CTI) which reflects community response to temperature increase (increasing CTI indicates an increase in relative abundance of more southerly species), and the temporal trend of the community specialisation index (CSI) which reflects community response to land use change (declining CSI indicates an increase of generalist species). We show that the breeding bird fauna underwent distinct directional change accompanied by significant changes both in CTI and CSI which suggests a causal connection between climate and land use change and bird community change. The assemblages of particular breeding habitats neither changed at the same speed and nor were they equally affected by climate versus land use changes. In the rapidly changing farmland community, CTI and CSI both declined slightly. In contrast, CTI increased in the more slowly changing forest and heath communities, while CSI remained stable. Coastal assemblages experienced both an increase in CTI and a decline in CSI. Wetland birds experienced the fastest community change of all breeding habitat assemblages but neither CTI nor CSI showed a significant trend. Overall, our results suggest that the interaction between climate and land use changes differs between habitats, and that comparing trends in CSI and CTI may be useful in tracking the impact of each determinant.

Numencdl vanation of the breeding bird community, its ecological subunits (guilds) and the 26 most numerous constituent species is analysed over 20 yr penod (1975)(1976)(1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994), and related to vanation m supply of defoliating caterpillars, tree seed crop, numbers of rodents and winter weather Maximum rates of increase between two years were less than twofold in most species Changes in numbers of individual species/guilds were either independent of each other or in parallel The pattern of numencal vanation was not related to taxonomic affinities, type of nest site, food types, or migratory habits Whole bird community and 13 of 26 species showed long-term increasing trends, only three species dechned Numbers remained basically stable dunng the first decade, increases were concentrated to the second decade Except tropical migrants (no long-term change) other migratory groups increased in numbers None of the measured environmental vanables showed parallel trends, which could account for the recorded trends Long-term trends and year-to-year fluctuations were not correlated The short-term vanation in bird numbers was to some extent correlated with (in decreasing order of importance) abundance of defoliating caterpillars, winter seventy, and changes in rodent numbers No correlation with tree seed crop was found Overall, a substantial part of the vanation in breeding bird numbers could not be explained by that set of factors This could be due to birds using wider spectrum of food sources than those measured, varying predator pressure and/or strong influences from outside the forest, swamping local relationships

“…Our data on population trends are not from the Breeding Bird Survey; rather, we rely on a 50-yr study (Kendeigh 1982) and supplement these data with our own surveys. Our focus is on populations within selected woodlots (I 0-500 ha) in the highly fragmented landscapes of central Illinois.…”

We examined the reproductive success and long-term population dynamics of Neotropical migrant birds in the fragmented landscapes of Illinois. Our primary objective was to assess whether annual variation in abundances and persistence of populations within woodlots was related to variation in reproductive success. Nesting success of migrants was so low in the woodlots where we sampled that it is unlikely that these populations are selfsustaining. Moreover, populations frequently disappear from and recolonize these woodlots. These data suggest that the source-sink metaphor for population dynamics within spatially structured populations is applicable to migratory birds in Illinois. The scale of this dynamic is unknown, but may be regional (i.e., midwestern U.S.).An important implication of this result is that census data must be interpreted carefully. For one woodlot, we detected no systematic trend in the overall abundances of migratory birds over much of the 20th century. Yet the viability of populations within that woodlot likely decreased dramatically over that time owing to increasing rates of nest predation and brood parasitism.Lack of data on dispersal is a major gap in understanding the population dynamics of Neotropical migrants and prescribing effective conservation measures.
