Bruno Massa, Auteur ; Camillo A. Cusimano, Auteur ; Beniamino Margagliotta, Auteur ; Roberto Galici, AuteurThe breeding ecology of the Blue Tit (Cyanistes caeruleus) and Great Tit (Parus major) was studied for 18 years in three different neighbouring habitats in Sicily, comprising oakwoods, reforested pine and a reforested mix of pine and broad-leave[...]NouveautéArticle
Francisco Castaño‐Vázquez, Auteur ; Javier Martínez, Auteur ; Santiago Merino, Auteur ; and Marco Lozano, AuteurSeveral models predict changes in the distributions and incidences of diseases associated with climate change. However, studies that investigate how microclimatic changes may affect host–parasite relationships are scarce. Here, we experimentally[...]Article
François Mesléard, Auteur ; N. Yavercovski, Auteur ; T. Dutoit, AuteurJuncus acutus and J. maritimus are two colonizers of coastal marsh rangeland with worldwide distribution. We tested the effect of salt, temperature, and photoperiod on the germination capacity of seeds of the two Juncus from the Rhône delta (sou[...]Article
Kristal N. Kostoglou, Auteur ; Wouter F. D. van Dongen, Auteur ; Michael A. Weston, AuteurEmbryonic vocalizations in birds may enable communication between embryos and incubating parents but responses of parents to embryonic vocalizations have not been measured experimentally. In two ground-nesting shorebirds, we compare parental car[...]Article
Joy Coppes, Auteur ; Jim-Lino Kämmerle, Auteur ; Karl-Eugen Schroth, Auteur ; Veronika Braunisch, Auteur ; Rudi Suchant, AuteurClimate change and associated changes in weather patterns have globally widespread effects on natural systems. Shifts in phenology can affect the reproductive success of birds by causing a mismatch between the onset of breeding and favourable co[...]Article
Kate F. Carstens, Auteur ; Reshma Kassanjee, Auteur ; Rob M. Little, Auteur ; Peter G. Ryan, Auteur ; Phillip A. R. Hockey, AuteurThe timing of breeding in birds has important consequences if food availability varies seasonally. Optimal timing of the most energetically demanding stages of breeding to coincide with peaks in food availability can increase breeding success. E[...]Article
Andrew J. Bladon, Auteur ; Paul F. Donald, Auteur ; Samuel E. I. Jones, Auteur ; Nigel J. Collar, Auteur ; Jarso Deng, Auteur ; Galgalo Dadacha, Auteur ; Yilma D. Abebe, Auteur ; Rhys E. Green, AuteurClimate may influence the distribution and abundance of a species through a number of demographic and ecological processes, but the proximate drivers of such responses are only recently being identified. The Ethiopian Bush-crow Zavattariornis st[...]Article
Chima J. Nwaogu, Auteur ; B. Irene Tieleman, Auteur ; Will Cresswell, AuteurIn some tropical birds, breeding seasonality is weak at the population level, even where there are predictable seasonal peaks in environmental conditions. It therefore remains unclear whether individuals are adapted to breeding at specific times[...]Article
Murray V. Ellis, Auteur ; Jennifer E. Taylor, AuteurWe used clearly defined measures of weather and time of day to determine their impacts on the number of bird species recorded in 5439 area-search surveys of 142 one-hectare sites in open temperate woodlands. Surveys recording the highest number [...]Article
Javier Bueno-Enciso, Auteur ; Rafael Barrientos, Auteur ; Esperanza S. Ferrer, Auteur ; Juan José Sanz, AuteurBecause extended incubation recesses, where incubating songbirds are away from nests for periods much longer than usual, occur infrequently, they have been treated as outliers in most previous studies and thus overlooked. However, egg temperatur[...]Article
Reesa Y. Conrey, Auteur ; Susan K. Skagen, Auteur ; Amy A. Yackel Adams, Auteur ; Arvind O. Panjabi, AuteurClimate change elevates conservation concerns worldwide because it is likely to exacerbate many identified threats to animal populations. In recent decades, grassland birds have declined faster than other North American bird species, a loss thou[...]Article
Camille Musseau, Auteur ; Simone Vincenzi, Auteur ; Dušan Jesenšek, Auteur ; Isabel Cantera, Auteur ; Stéphanie Boulêtreau, Auteur ; Frédéric Santoul, Auteur ; Alain Jean Crivelli, AuteurDans Ecosphere (6 - 12 )Dietary plasticity of populations can be associated to ontogenetic diet preferences and depends on the size-structure of populations. Dietary niche characterizes the functional role of organisms in a food web, as it reflects both resources' dive[...]Article
Elisabeth M. A. Strain, Auteur ; Jim van Belzen, Auteur ; Paolo Comandini, Auteur ; Joanne Wong, Auteur ; Tjeerd J. Bouma, Auteur ; Laura Airoldi, Auteur* Changing climate threatens the structure and function of saltmarshes, which are often severely degraded by other human perturbations. Along the Mediterranean coastline, increasing temperature and decreasing rainfall have been hypothesised to t[...]Article
Thomas W. Bodey, Auteur ; Russell Barnett, Auteur ; Christopher R. du Feu, Auteur ; John R. Clark, Auteur ; Stuart Bearhop, AuteurDans Ibis (163(1) 2021)Global anthropogenic changes are significantly impacting the ecology and evolution of many species. Among temperate taxa, changes to reproductive phenology as a result of warming springs are apparent. However, how such responses to abiotic chang[...]Article
Giuseppe De Marchi, Auteur ; Giorgio Chiozzi, Auteur ; Giacomo Dell'Omo, Auteur ; Mauro Fasola, AuteurWe used GPS data-loggers, video-recordings and dummy eggs to assess whether foraging needs may force the low incubation attentiveness (< 55%) of the Crab Plover Dromas ardeola, a crab-eating wader of the Indian Ocean that nests colonially in bur[...]
