The recruitment of Phillyrea latifolia L. (Oleaceae), a bird—dispersed tree Mediterranean forest, is described. Fruit removal by birds, seed rain, post—dispersal predation, germination, and seedling emergence, survival, establishment were studied. main objective was testing whether dispersal birds produced predictable shadow as result coupled patterns establishment. P. mast—fruiting species large fruit crops in only 2 (1981 1989) out 15 yr (1978—1992). We report here on the 1989 fruiting...
Abstract Aim Parental care improves the survival of offspring and therefore has a major impact on reproductive success. It is increasingly recognized that coordinated biparental necessary to ensure in hostile environments, but little known about influence environmental fluctuations parental cooperation. Assessing impacts stochasticity, however, essential for understanding how populations will respond climate change associated increasing frequencies extreme weather events. Here we investigate...
In the Kentish Plover Charadrius alexandrinus one of adults, typically female, deserts brood when chicks are a few days old. Once parental care is terminated, adults may initiate second nesting attempt if sufficient time remains within season. For these nests, individuals pair with different mates from those first attempt, thus becoming sequentially polygamous. small population Plovers in Fuente de Piedra lake (southern Spain), duration biparental broods was longer than other localities. It...
Abstract Gene flow promotes genetic homogeneity of species in time and space. can be modulated by sex‐biased dispersal that links population genetics to mating systems. We investigated the phylogeography widely distributed K entish plover C haradrius alexandrinus . This small shorebird has a large breeding range spanning from W estern E urope J apan exhibits an unusually flexible system with high female dispersal. analysed structure gene using 427‐bp fragment mitochondrial (mt DNA ) control...
Social behaviours are highly variable between species, populations and individuals. However, it is contentious whether behavioural variations primarily moulded by the environment, caused genetic differences, or a combination of both. Here we establish that biparental care, complex social behaviour involves rearing young both parents, differs closely related populations, then test two potential sources variation in parental populations: ambient environment differentiation. We use 2904 hours...
Abstract Environmental trace element composition can have an important impact on ecosystem and population health as well individual fitness. Therefore, carefully assessing bioaccumulation of elements is central to studies investigating the ecological pollution. Colonial birds are bioindicators since non‐invasive sampling easily be achieved through chick feathers, which controls for some confounding factors variability (age environmental heterogeneity). However, additional factor, external...
1. Contrary to the generally high level of natal philopatry (i.e. likelihood that individuals breed at their colony) found in first-breeding colonial birds, little is known later life. Most hypotheses advanced explain are valid all ages. However, for young and inexperienced benefits may be counterbalanced by costs intraspecific competition colony making dispersal temporarily advantageous. In turn, experience increase competitive ability make advantageous again. 2. We evaluated this...
The unusually high quality of census data for large waterbirds in Europe facilitates the study how population change varies across a broad geographical range and relates to global change. wintering greylag goose Anser anser Atlantic flyway spanning between Sweden Spain has increased from 120 000 610 individuals over past three decades, expanded its northwards. Although sizes recorded January have all seven countries range, we found pronounced northwards latitudinal effect which rate increase...
ABSTRACT To make many sites accessible, humans have constructed roads. New layers of different materials (pipeclay, gravel, etc.) are added to the original soil for construction unpaved roads, which in marshy areas readily used as nesting by ground‐nesting waterbirds. On other hand, disposal dredged has been a specific management strategy facilitate waterbirds order compensate loss natural habitats. The introduced substrates may differ their physical properties (e.g., colouration) from ones,...
The aim of this study was to examine whether the energetic costs reproduction explain offspring desertion by female shorebirds, as is suggested differential parental capacity hypothesis. A prediction hypothesis that, in species with biparental incubation which females desert from brood care after hatching, body condition should decline laying a point at their reserves are too low for continuing care. We tested on Kentish plovers (Charadrius alexandrinus) both sexes incubate but before chicks...
The conservation of many species depends on sustainable economic activities that shape their habitats. use these anthropogenic habitats may change quickly owing to world trade globalization, market reorientations, price volatility or shifts in subsidy policies. recent financial crisis has produced a global impact the economy. How this have affected beneficial biodiversity not yet been documented. However, consequences could be particularly acute for sensitive climate change, jeopardizing...
We studied the consequences of intraclutch egg‐size variation in Kentish Plovers Charadrius alexandrinus southern Spain to test hypothesis that females allocate resources preferentially eggs with greatest survival potential. Second were larger and had a greater hatching success than other clutch. However, we did not find unequivocal support for differential allocation hypothesis, because egg failures according laying order due causes predicted by change was consistent between successive...
