Biological invasions are a global concern in agriculture, food production and biodiversity. Among the invasive species, some hornets known to have serious effects on honey bees, as found during invasion of Vespa velutina Europe. The recent findings mandarinia individuals Washington state west coast USA raised alarm whole country. Here we estimate potential spread V. USA, analyzing its impacts bee colonies, economic losses industry bee-pollinated croplands.We that could colonize Oregon states...
Background Most hypotheses on population limitation of small mammals and their predators come from studies carried out in northern latitudes, mainly boreal ecosystems. In such regions, many specialize voles predator-prey systems are simpler compared to southern ecosystems where predator communities made up mostly generalists more complex. Determining food generalist is difficult due capacity switch alternative prey when the basic becomes scarce. Methodology We monitored density a raptor,...
Depending on the mosaic of habitats that is created, forest fragmentation can reduce abundance and diversity birds. Temperate deciduous forests in South America are rapidly being replaced by pine plantations, causing changes for both breeding migrant We examined differences avian species richness three areas: a reserve with continuous tracts native forest, fragments plantations. Four were negatively affected fragmentation, their declining from to Fourteen not eight had significantly...
Nest‐site fidelity is a life‐history trait of birds that may produce benefits in terms fitness. We studied the relationship between breeding success and nest White Stork Ciconia ciconia . also how other factors such as age, sex, habitat, colony size productivity previous attempts might interfere with this relationship. Our results showed pairs higher rates have lower failure rates, season influenced frequency change following season. In addition, curvilinear was found age fidelity. These...
Indicator models of sexual selection predict that the expression ornaments should be condition dependent. This is only partly supported by data, as many studies do not find positive associations between and condition. The reason for this inconsistency remains poorly understood. It has been hypothesized environmental context may explain variation in dependence traits, with stronger relationships expected harsher environments. However, field tests idea are scarce. We studied 9 populations wild...
Diurnal human activity and domestic dogs in agro-forestry mosaics should theoretically modify the diurnal habitat use patterns of native carnivores, with these effects being scale-dependent. We combined intensive camera trapping data Bayesian occurrence probability models to evaluate both nocturnal space by carnivores a mosaic land-use types southern Chile. A total eight species were recorded, including human-introduced dogs. During day most frequently detected culpeo fox cougar. Conversely,...
Competition for resources (e.g. mates or food) is the main evolutionary explanation conspicuous ornaments in males, although this idea not generalized females. Whether expression of melanic coloration dependent on environmental conditions remains controversial. We studied three different melanin-based female traits Eurasian kestrel Falco tinnunculus, a sexually dichromatic species, period 10 years: grey rump and tail width black subterminal band. analysed these within-individual variation...
The duration of the postfledging dependence period (PFDP) is supposed to be modulated by parent–offspring conflict: Offspring should extract highest levels parental investment, although parents may respond setting fixed limits level investment or raising costs attempts additional investment. In this context, longer PFDPs are expected in nests tended higher quality and dominant siblings. We explored these hypotheses with a combination experimental correlative results. First, we food...
Nest size and nest building behaviour affect individual fitness thus, selection may act on these traits. Most data nesting come from species that build a for each new breeding attempt, whereas almost nothing is known regarding reusers. Here, the association between behaviour, occupation date as well success of white stork Ciconia ciconia, migratory with reuse, presented. Large nests were occupied earlier showed higher success, even accounting confounding effect breeder's age. In addition,...
Abstract Secondary sexual traits displayed by males and females may have evolved as a signal of individual quality. However, both quality investment on producing or maintaining enhanced change individuals age. At the same time, costs associated to produce might be attenuated increased if environmental conditions are benign worse respectively. Accordingly, expected shape association between expression their reproductive outcome Nonetheless, little is known about influence co‐variation...
Success in sibling competition is one of the main factors determining individual body condition early stages life and consequently offspring survival fitness. In birds, most studies on this topic have been focused nesting period, but still continues during postfledging period. We studied over 3 years postfledgling dependence period Eurasian kestrel Falco tinnunculus, a reversed sexually size dimorphic species. Contrary to that stage, male fledglings showed higher competitive capacity than...
