Abstract: Despite extensive research on the effects of habitat fragmentation, ecological mechanisms underlying colonization and extinction processes are poorly known, but knowledge these is essential to understanding distribution persistence populations in fragmented habitats. We examined through multiseason occupancy models that elucidated patch‐occupancy dynamics Middle Spotted Woodpeckers (Dendrocopos medius) northwestern Spain. The number occupied patches was relatively stable from 2000...
Nests are structures built to support and protect eggs and/or offspring from predators, parasites, adverse weather conditions. mainly constructed prior egg laying, meaning that parent birds must make decisions about nest site choice building behavior before the start of egg-laying. Parent should be selected choose sites build optimally sized nests, yet our current understanding clutch size-nest size relationships is limited small-scale studies performed over short time periods. Here, we...
Abstract The increase in size of human populations urban and agricultural areas has resulted considerable habitat conversion globally. Such anthropogenic have specific environmental characteristics, which influence the physiology, life history, population dynamics plants animals. For example, date bud burst is advanced compared to nearby natural areas. In some birds, breeding success determined by synchrony between timing peak food abundance. Pertinently, caterpillars are an important source...
Summary Secondary hole‐nesting birds that do not construct nest holes themselves and hence regularly breed in boxes constitute important model systems for field studies many biological disciplines with hundreds of scientists amateurs involved. Those research groups are spread over wide geographic areas experience considerable variation environmental conditions, researchers provide varying designs may inadvertently introduce spatial temporal reproductive parameters. We quantified the...
While ecosystem engineering is a widespread structural force of ecological communities, the mechanisms underlying inter-specific associations between engineers and resource users are poorly understood. A proper knowledge these is, however, essential to understand how communities structured. Previous studies suggest that increasing quantity resources provided by enhances populations users. In long-term study (1995-2011), we show quality (i.e. tree cavities) also key feature explains in...
Through physical state changes in biotic or abiotic materials, ecosystem engineers modulate resource availability to other organisms and are major drivers of evolutionary ecological dynamics. Understanding whether how interchangeable for users different habitats is a largely neglected topic engineering research that can improve our understanding the structure communities. We addressed this issue cavity-nest web (1999–2011). In aspen groves, presence mountain bluebird (Sialia currucoides)...
Despite its relevance for the persistence of populations, ecological mechanisms underlying habitat use decisions juvenile birds are poorly understood. We examined postfledging selection radio‐tracked middle spotted woodpeckers Dendrocopos medius at multiple hierarchically‐nested spatial scales in NW Spain. At landscape and home range scales, old oak forest was most used selected habitat, young forests pine plantations were avoided, riverside as available. a lower scale, larger diameter trees...
The high extinction risk of small populations is commonly explained by reductions in fecundity and breeder survival associated with demographic environmental stochasticity. However, ecological theory suggests that population extinctions may also arise from the number floaters able to replace lost breeders. This can be particularly plausible under harsh fragmentation scenarios, where species must survive as subjected severe effects Using a woodpecker study fragmented habitats (2004-2016), we...
Despite its relevance for the dynamics of populations, ecological mechanisms underlying juvenile and adult survival are poorly known in most bird species. This study focuses on effect habitat fragmentation early post‐fledging, first‐year middle spotted woodpecker Dendrocopus medius by combining data radio‐tagged ringed birds. Among juveniles, deaths occurred during first three weeks after fledging (survival rate: 0.359±0.077) were mainly caused predation. After independence, birds faced...
We examined the demographic response of Middle Spotted Woodpeckers (Dendrocopos medius) to habitat fragmentation in an 880-km2 study area Cantabrian Mountains (northwest Spain), 2000–2005. used a set reproductive parameters examine 26–72 nests 10–14 patches. Fifty-nine 72 (81.9%) were successful (i.e., at least one fledgling was produced). Average clutch size 5.1. Seventy 94 hatchlings (74.4%) survived fledging. Mean number fledglings for 3.1, average mass 50.6 g, and mean fledging date 21...
Abstract Population divergence could be strongly affected by species’ ecology and might not a direct response to climate‐driven environmental change. We tested this in the middle spotted woodpecker ( Dendrocoptes medius ) , non‐migratory, low‐dispersal habitat specialist associated with old deciduous forests of Western Palearctic. present first phylogeographic study species integrating genetic data (three mitochondrial loci, one autosomal Z‐linked intron) distribution modelling. Based on...
Coexistence between great tits Parus major and blue Cyanistes caeruleus, but also other hole-nesting taxa, constitutes a classic example of species co-occurrence resulting in potential interference exploitation competition for food breeding roosting sites. However, the spatial temporal variations coexistence its consequences remain poorly understood. We used an extensive database on reproduction nest boxes by based 87 study plots across Europe Northern Africa during 1957-2012 total 19,075...
During the colonization of remote Pacific Islands, founding communities forged novel interaction spheres within newly settled archipelagos. We report on new research geographic range in first centuries occupation New Zealand based geochemical source identifications from obsidian assemblages found along coast Otago region southern South Island. Results suggest that while there is evidence for spanning entire archipelago, logistical limitations long-distance mobility long north-south axis...
Twelve polymorphic microsatellite loci were developed for Dendrocopos medius. Polymorphism was assessed 27 individuals from the southwesternmost population of this woodpecker species. The number alleles per locus ranged three to seven, with observed heterozygosity values 0.444 0.852. Genotypic frequencies conformed Hardy-Weinberg equilibrium, and no evidence linkage disequilibrium observed. Multilocus genotypes resulting set markers will be useful determine genetic diversity differentiation...

As expected, spring increases advances winter is reduced both species. Density affected tit. Specifically, density increased species started reproduce later. date....
Abstract Ecological theory and recent empirical studies show that the persistence of spatially structured populations – those composed separated local connected by dispersal may require maintenance pools floaters (nonbreeding but sexually mature individuals) rescue small from extinction replacing lost breeders. Regardless breeding populations, also depend on sufficient numbers colonizations counteract extinctions. Given their intrinsic potential mobility, have been proposed to promote...
Abstract Context Natal dispersal critically influences eco-evolutionary dynamics and the persistence of spatially structured populations. As both short- long-distance movements contribute to population in fragmented landscapes, understanding requires assessing phenotypic environmental effects on a wide range distances. Objectives To assess correlates landscapes. Methods We radio-tracked juvenile middle spotted woodpeckers landscapes emigration age, transfer duration (in days), Results Large...
Deep phylogeographic structure in mitochondrial DNA not reflected morphological variation has been uncovered a number of species over the past few decades. However, inferred based solely on can be misleading and might reflect true history evolutionary lineages. Consequently, such cases should further investigated genome‐wide data. One these examples is provided by Middle Spotted Woodpecker Dendrocoptes medius , non‐migratory habitat specialist associated with old deciduous forests Western...
