Comparacion de la eficacia las falanges respecto humeros y femures para estimacion edad en lagartijas mediante esqueletocronologia La permite estimar a partir una sola captura (tomando muestra hueso), lo que hace innecesario un seguimiento largo plazo. No obstante, los estudios esqueletocronologicos suelen implicar muerte del animal obtener el hueso. Nosotros probamos fiabilidad (que pueden obtenerse sin matar al animal), comparando estimada con falanges. Nuestros resultados muestran es...
Human-modified habitats rarely yield outcomes that are aligned with conservation ideals. Landscapes subdivided by roads no exception, precipitating negative impacts on populations due to fragmentation, pollution, and road kill. Although many in human-modified show evidence for local adaptation, does environmental change outright benefits of interest. Contrary expectations, we report surprising experienced amphibian breeding dwelling proximity roads. We roadside the wood frog, Rana sylvatica,...
Predation is one of the main selective forces in nature, frequently selecting potential prey for developing escape strategies. Escape ability typically influenced by several morphological parameters, such as morphology locomotor appendices, muscular capacity, body mass, or fluctuating asymmetry, and may differ between sexes age classes. In this study, we tested relationship among these variables jumping performance 712 Iberian green frogs Pelophylax perezi from an urban population. The...
Salamandra has a very patchy distribution in North Africa, where it is restricted to few humid or sub-humid forested regions Morocco and Algeria (fig.1; see also Donaire-Barroso Bogaerts, 2003 andThiesmeier, 2004).One such area the Beni Snassen massif, situated northeast (locality 5 fig.1).The presence of algira Bedriaga, 1883 this locality was reported for first time by Melhhaoui Chavanon (1989).After record, based on an observation made student some larvae Jbel Ouartass, there have not...
Global amphibian decline is due to several factors: habitat loss, anthropization, pollution, emerging diseases, and global warming. Amphibians, with complex life cycles, are particularly susceptible alterations, their survival may be impaired in anthropized habitats. Increased mortality a well-known consequence of anthropization. Life-history theory predicts higher reproductive investment when increased. In this work, we compared age, body size, different indicators investment, as well prey...
Mediterranean woodland environments are characterised by high spatial and temporal heterogeneity, which means the inhabiting species face a wide variety of selective pressures. Species may respond differently to habitat heterogeneity so distinct eco-evolutionary scenarios be responsible for inter-habitat variability in reproductive strategies observed certain species. The inter-forest some traits passerines has been examined comparing forest patches or separated fragments. However, there is...
The timing of organisms' senescence is developmentally programmed but also shaped by the interaction between environmental inputs and life-history traits. In ectotherms, ageing dynamics are still poorly understood even though their body temperature, metabolism, or growth trajectory very sensitive to changes. Here, we investigated role traits such as age, sex, size, condition, tail autotomy (i.e self-amputation) in shaping telomere length six populations Algerian sand lizard (Psammodromus...
Several ectoparasites parasitise nestlings decreasing their body condition, growth and survival. To minimise any loss of fitness due to ectoparasites, birds have developed a wide variety defence mechanisms, potentially including hatching asynchrony. According the Tasty Chick Hypothesis (TCH), cost parasitism would be reduced if tend eat on less immunocompetent nestlings, typically last-hatched chick in asynchronously hatched broods, as they are poor condition. Two predictions TCH that immune...
Abstract The genetic variability and the potential distribution under past (Last Glacial Maximum; LGM (MIROC CCSM simulations)) present conditions were studied for anguid Hyalosaurus koellikeri , using analyses of two mitochondrial (ND1 ND2) one nuclear (PRLR) gene species modelling (SDM) including 19 geographical coordinates, covering most its range. Unexpectedly, results show that H. presents a very low level both in genes studied. predicted revealed large north eastwards directions, with...
Host traits can significantly influence patterns of infection and disease. Here, we studied the helminths par - asitizing Italian edible frog Pelophylax kl. hispanicus, giving special attention to relationship between parasites host such as sex, snout vent length, weight body condition. The helminth community was composed seven species: three trematode species (Diplodiscus subclavatus, Gorgodera cygnoides, Pleurogenes claviger), nematode (Icosiella neglecta, Oswaldocruzia filiformis ,...
Abstract Parasitism is one of the main selective forces in nature, strongly affecting host fitness. Still, knowledge incomplete concerning how variation probability and intensity infestation depends on body condition, sex or geographic variables. Here, I study bloodsucking mites parasitizing Atlas day gecko ( Quedenfeldtia trachyblepharus ) depending elevation, High (Morocco). Parasite prevalence was 58.75%, infection decreased with condition. However, parasitism tended to increase The...
Genetic differentiation between populations inhabiting ecologically different habitats might appear because of limited dispersal and gene flow, which may lead to patterns phenotypic divergence local adaptation. In this study, we use dispersal, genotypic (24 microsatellite loci) (body size clutch size) data analyse genetic structuring in a blue tit ( Cyanistes caeruleus ) population continuous heterogeneous woodland along valley. The two slopes the valley differ their forest formations...
Lifespan is one of the main components life history. Shorter lifespans can be expected in marginal habitats. However, case ectotherms, lifespan typically increases with altitude, even though temperature-one factors to determine ectotherms' history-declines elevation. This pattern explained by fact that a shorter activity time favors survival. In this study, we analyzed how and other life-history traits lizard Psammodromus algirus vary along 2,200 m elevational gradient Sierra Nevada (SE...
Animals frequently show complex colour patterns involved in social communication, which attracts great interest evolutionary and behavioural ecology. Most researchers interpret that each animals with multiple patches may either signal a different bearer’s trait or redundantly convey the same information. Colour signals, moreover, vary geographically according to bearer qualities. In this study, we analyse sources of variation eastern clade lizard Psammodromus algirus. Sexual dichromatism...
Wild birds are hosts of Culicoides from as early on the nesting stage when constrained to their nests. However, environmental factors which determine abundance and composition species within each bird nest still understudied. We sampled Eurasian blue tit (Cyanistes caeruleus) nests found in 2 types forests located southern Spain. Firstly, we monitored a dry Pyrenean oak deciduous forest humid mixed comprising Holm oaks throughout consecutive years. During 3rd year, performed cross-fostering...
Abstract A cornerstone in parasitology is why some species or populations are more parasitized than others. Here we examine the influence of host characteristics and habitat on parasite prevalence. We studied helminths parasitizing Pyrenean brook newt Calotriton asper ( n = 167), paying special attention to relationship between parasites ecological factors such as habitat, sex, ontogeny, body size age host. detected two parasites, Megalobatrachonema terdentatum (Nematoda: Kathlaniidae)...
Abstract Human activities have caused massive losses of natural populations across the globe. Like many groups, amphibians experienced substantial declines worldwide, driven by environmental changes such as habitat conversion, pollution, and disease emergence. Each these drivers is often found in close association with presence roads. Here we report a novel consequence roads affecting an amphibian native to much North America, wood frog ( Rana sylvatica ). Across 38 distributed from southern...
Ecologia reproductora del alcaudon meridional, Lanius meridionalis , en un agrosistema sudeste de Espana: el desconcertante excelente exito reproductivo una poblacion decrecimiento La esta disminuyendo a escalas europea y espanola. Una posible causa este podria ser la disminucion reproductor debido escasa disponibilidad presas medios agrarios. En estudio se analiza ecologia meridional situado las Lomas Padul (SE Espana). Los resultados sugieren que encuentra decrecimiento; no obstante,...
