Invasive species can displace natives, and thus identifying the traits that make aliens successful is crucial for predicting preventing biodiversity loss. Pathogens may play an important role in invasive process, facilitating colonization of their hosts new continents islands. According to Novel Weapon Hypothesis, colonizers out-compete local native by bringing with them novel pathogens which are not adapted. In contrast, Enemy Release Hypothesis suggests flourishing because they have left...
Scientists have long been trying to understand why the Neotropical region holds highest diversity of birds on Earth. Recently, there has increased interest in morphological variation between and within species, how climate, topography, anthropogenic pressures may explain affect phenotypic variation. Because data are not always available for many species at local or regional scale, we limited our understanding intra- interspecies spatial Here, present ATLANTIC BIRD TRAITS, a set that includes...
Abstract Parkinson's disease (PD) is a progressive and chronic neurodegenerative of the central nervous system. Early treatment for PD efficient; however, long-term systemic medication commonly leads to deleterious side-effects. Strategies that enable more selective drug delivery brain using smaller dosages, while crossing complex brain-blood barrier (BBB), are highly desirable ensure efficacy decrease/avoid unwanted outcomes. Our goal was design test neurotherapeutic potential forefront...
Knowing the genetic variation that occurs in pathogen populations and how it is distributed across geographical areas essential to understand parasite epidemiology, local patterns of virulence, evolution host‐resistance. In addition, important identify pathogens are evolutionarily independent thus ‘free’ adapt hosts environments. Here, we investigated globally distributed, highly invasive avian malaria Plasmodium relictum , which has several distinctive mitochondrial haplotyps (cyt b...
Blood parasites play a fundamental role in the ecology and evolution of passerine birds because they are able to affect fitness survival their hosts. The prevalence avian malarial among host species can vary from 0 100% but ecological evolutionary reasons for this variation not clear. In study we tested if height or type nest, body mass social system, which believe variables associated with exposure hosts vectors, could explain blood bird community Cerrado biome central Brazil. We found...
SUMMARY Studies on avian haemosporidia are the rise, but we still lack a basic understanding of how ecological and evolutionary factors mold distributions among species in same bird community. We studied structure organization local haemosporidian assemblage (genera Plasmodium Haemoproteus ) Cerrado biome Central Brazil for 5 years. obtained 790 blood samples from 54 which 166 (21%) were infected with haemosporidians based molecular diagnostics. Partial sequences parasite cytochrome b gene...
Abstract Assessing the biological relevance of variance components estimated using Markov chain Monte Carlo (MCMC)‐based mixed‐effects models is not straightforward. Variance estimates are constrained to be greater than zero and their posterior distributions often asymmetric. Different measures central tendency for these can therefore vary widely, credible intervals cannot overlap zero, making it difficult assess size statistical support among‐group variance. Statistical assessed through...
Abstract Passive acoustic monitoring (PAM) is increasingly popular in ecological research, but recording and analyzing large amounts of data still a critical bottleneck for the long‐term multiple species. We evaluated how temporal spatial sampling effort affects species diversity estimates using set 14,045 1‐min recordings from various neotropical birds anuran communities. Our goals were to evaluate (i) daily vocal activity cycle anurans, (ii) effect structure (e.g., number minutes listened...
Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes more likely to become extinct. The prevention of extinctions is an urgent matter knowledge on the ecology threatened required outline conservation strategies. In this study, we investigate potential current endemic Atlantic Forest bird Kaempfer's tody‐tyrant Hemitriccus kaempferi , advance efforts for species. We used a model (SDM) assess detect...
In this study, we tested the potential of restored areas to maintain biodiversity in scope a recently proposed category protected area called "Restoration Reserves". To accomplish this, compared bird richness and functional group structure two small forest fragments (<250 ha) with adjacent reforested (9 7 years reforestation). Reforested had equal or higher similar structure. These results indicate that are capable maintaining current levels reducing species extinction debt fragments, which...
Abstract Aim Environmental and spatial factors are broadly recognized as important predictors of beta diversity patterns. However, the scale at which patterns evaluated will affect outcoming results. For example, studies larger scales usually find processes main predictor In this study, we evaluate how change when analyses conducted different by reducing analysis in a hierarchical manner. Location Atlantic Forest biome. Taxon Chiroptera. Methods Information on occurrence 59 bat species were...
Abstract Species that are introduced to novel environments can lose their native pathogens and parasites during the process of introduction. The escape from negative effects associated with these natural enemies is commonly employed as an explanation for success expansion invasive species, which termed enemy release hypothesis (ERH). In this study, nested PCR techniques microscopy were used determine prevalence intensity (respectively) Plasmodium spp. Haemoproteus in house sparrows urban...
Introduced species are interesting systems for the study of contemporary evolution in new environments because their spatial and temporal scales. For this we had three aims: (i) to determine how genetic diversity differentiation introduced populations house sparrow (Passer domesticus) Brazil varies with range expansion, (ii) compares ancestral European populations; (iii) whether selection or drift has been more influential on phenotypic divergence. We used six microsatellite markers genotype...
Despite many studies on avian blood parasites, we still have a limited understanding of the mechanisms that drive patterns haemosporidian infection among tropical birds, including effects associated with sex, age, and seasonality. Using molecular morphological methods for blood-parasite detection, found juvenile White-banded Tanagers (Neothraupis fasciata (Lichtenstein, 1823)) had lower prevalence than adults in population within central Brazil. However, no sex or seasonal differences were...
Abstract Aim The increasing spread of vector‐borne diseases has resulted in severe health concerns for humans, domestic animals and wildlife, with changes land use the introduction invasive species being among main possible causes this increase. We explored several ecological drivers potentially affecting local prevalence richness avian malaria parasite lineages native introduced house sparrows ( Passer domesticus ) populations. Location Global. Time period 2002–2019. Major taxa studied...
Egg characteristics have been used to determine egg maternity for birds in situations where two or more females lay eggs a single nest (as communal breeders and intraspecific parasites). We assessed the applicability of morphometry eggshell appearance ascribing ownership clutches guira cuckoos Guira , species up seven may joint nest. both combined variables (including mass, length, width, shape variables), index test whether laid by each female were similar but different from other females....
Abstract The delineation of unique areas in biodiversity is crucial for conservation planning. However, identification distinct biotas a challenging task. In this study, we use an objective analytical process to test if bird and plant species composition three different forest formation the Atlantic Biome sufficiently merit recognition ecoregions. We also evaluated how current climatic spatial factors shape distribution plants birds. Sampling localities were selected types southern Brazil:...
Human activities have modified landscapes worldwide, promoting fragmentation and isolation of forest habitats. Such landscape modifications are responsible for changes in species composition due to extinction colonization events. Forest dynamism is usually affected by when remaining fragments small isolated, but more stable large connected. In this study we verified bird during 23 years monitoring at the Mata dos Godoy State Park (PEMG). We aimed evaluate avian community reserve, as well its...
