Human-induced environmental change and habitat fragmentation pose major threats to biodiversity require active conservation efforts mitigate their consequences. Genetic rescue through translocation the introduction of variation into imperiled populations has been argued as a powerful means preserve, or even increase, genetic diversity evolutionary potential endangered species [1Weeks A.R.

Adaptive radiation is the rapid diversification of a single lineage into many species that inhabit variety environments or use resources and differ in traits required to exploit these. Why some lineages undergo adaptive not well-understood, but filling unoccupied ecological space appears be common feature. We construct complete, dated, species-level phylogeny endemic Vangidae Madagascar. This passerine bird represents classic, poorly known, avian radiation. Our results reveal an initial...
Changes in morphology have been postulated as one of the responses animals to global warming, with increasing ambient temperatures leading decreasing body size. However, results previous studies are inconsistent. Problems related analyses trends size may be short-term nature data sets, selection surrogates for size, appropriate models analyses, and interpretation change response ecological drivers other than climate irrespective Using generalized additive models, we analysed three...
Avian malaria parasites (Plasmodium spp.) and other Haemosporida (Haemoproteus Leucocytozoon form a diverse group of vector-transmitted blood that are abundant in many bird families. Recent studies have suggested corvids may be an important host for Plasmodium spp. To investigate the diversity resident carrion crows (Corvus corone) Eurasian Magpies (Pica pica) southwest Germany, 100 liver samples were examined using nested PCR method to amplify 1063 bp fragment haemosporidian mitochondrial...
Observations on the diet and feeding behaviour of naturalised Yellow-headed Amazona oratrix Blue-fronted Amazon Parrots aestiva xanthopteryx their hybrids were carried out in city Stuttgart, southwest Germany, only European known to host an established population. Food items taken ranged from bark, young shoots, flower leaf buds, flowers, seeds fruit. Since introduction 1984, a total 64 food plant taxa 23 families identified, amongst them 37 native taxa, 27 non-native trees shrubs. resources...
Avian malaria occurs almost worldwide and is caused by Haemosporida parasites (Plasmodium, Haemoproteus Leucocytozoon). Vectors such as mosquitoes, hippoboscid flies or biting midges are required for the transmission of these parasites. There few studies about avian on Madagascar but none suitable vectors. To identify vectors Plasmodium Madagascar, we examined head, thorax abdomen 418 mosquitoes from at least 18 species using a nested PCR method to amplify 524 bp fragment haemosporidian...
Neobiota, introduced or escaped non-native species, rank among the most important threats to biodiversity (e.g. Lövei 1997, Smith et al. 2005), negatively impacting on indigenous species through predation, competition for limited resources, introduction of parasites diseases, hybridization with native induced habitat deterioration, biotic homogenization (Blackburn 2009). The occurrence and spread neobiota has increased dramatically in recent decades, particularly industrialized world, due...
The development of new molecular methods has significantly improved the detection and identification avian haemosporidian parasites (Plasmodium, Haemoproteus Leucocytozoon) compared to microscopic examination. Very large numbers previously hidden Haemosporida species a wide range hosts have thus been discovered in last two decades. However, test parameters various remain largely unevaluated. In this study, merits microscopy, multiplex PCR, nested PCR were identify infection status three...
Abstract The chemical industry is the leading sector in EU terms of added value. However, contaminants pose a major threat and significant costs to environment human health. While legislation international conventions aim reduce this threat, regulators struggle assess manage risks, given vast number substances involved lack data on exposure hazards. European Green Deal sets ‘ zero pollution ambition for toxic free ’ by 2050 Chemicals Strategy calls increased monitoring chemicals environment....
During their journeys, migratory birds encounter a wider range of parasites than residents, transporting them over vast distances. While some are widely distributed, transmission is not inevitable and depends on the presence competent arthropod vectors as well parasite compatibility with native bird species. Distinguishing between distribution areas crucial for monitoring assessing risks to species, areas, appropriate conditions, could become potential areas. In this study, blood samples...
Abstract With the increasing urbanization of last decades, more and bird species occur in urban habitats. Birds which thrive habitats often have a higher tolerance toward human disturbance show behaviors differ from their rural counterparts. There is evidence that many genetic basis. One candidate gene dopamine receptor D4 (DRD4), has been associated with fear thus, flight initiation distance (FID). In this study, we analyzed segment DRD4 greylag geese Anser anser , describing variability...
Abstract Stonechats (genus Saxicola ) are passerine birds with an extraordinarily large breeding distribution. Recent studies provide strong evidence that the taxon shows far greater geographic differentiation than originally suspected, African, Siberian and European stonechats forming distinct, monophyletic groups have been suggested to be species in their own right. Here, we present additional data on among African stonechats, torquatus . Nucleotide sequences of mitochondrial NADH...
Abstract The nectarivorous common sunbird asity ( Neodrepanis coruscans ) is phylogenetically closely related to the frugivorous velvet Philepitta castanea ), yet it shares similar habitat and foraging behaviour as Malagasy sunbirds Cinnyris spp.). As ecological factors have been shown influence blood parasite prevalence, should be tested whether abundance, prevalence diversity of N. are more than its relative. Therefore, samples n = 156) smears 60) were for different parasites...
Data on longevity is a prerequisite to understand the life-history strategies of species. For Malagasy songbirds no information has been previously published. Therefore, we studied their in capture–recapture effort rainforest eastern Madagascar (Maromizaha, Andasibe) between 2003 and 2016. We present first data 23 species songbirds. A female Dark Newtonia amphichroa (Vangidae) Grey-crowned Greenbul Bernieria cinereiceps (Bernieridae) attained an age at least 12 years, followed by two male...
Abstract The horizontal and vertical distribution of mosquito species was studied in Maromizaha rainforest, Madagascar. In November 2014, using light traps that were placed four habitat types, ranging from degraded forest to primary rainforest. December 2016, near the ground elevated canopy. From survey, 476 adults collected: Uranotaenia (52.10%) Culex (35.2%) most abundant genera. highest numbers mosquitoes observed rainforest edge habitat, while diversity within 276 genus represented...
