Due to their high mobility, large vertebrates are efficient carriers of allochthonous matter and energy. Waterbirds congregate in breeding colonies, while feed in surrounding aquatic and terrestrial areas, promoting nutritional pulses to nutrient-poor environments. In southern Brazil, a swamp forest on an estuarine island is used by waterbirds for...

Urbanization is a major form of landscape transformation that often results in habitat degradation and loss for birds. However, effects on avian populations are trait- and context-dependent, and persistence at urban patches is likely to be a function of habitat availability at the landscape scale. Here, we aimed to assess the breeding performance a...

en The central-peripheral hypothesis states that the demographic performance of a species decreases from the centre to the edge of its range. Peripheral populations are often smaller and tend to occur under different and suboptimal conditions from those of core populations. Peripheral populations can also coexist during part of their annual cycle w...

Large Procellariiformes (albatrosses and petrels) constitute a highly threatened group of birds, for which bycatch in fisheries is the most prevalent threat. At-sea intentional killing and post-capture, handling-related injuries, remain poorly understood menaces. Here, we report fishermen off southern Brazil trying to reduce bait depredation in pol...

The South American Painted snipe – Nycticryphes semicollaris is a secretive shorebird endemic to South America that inhabits lowlands, high saltmarshes and flooded grasslands. Since its crepuscular behavior and habitat used, its biology is poorly known, and Feather molt and breeding strategy associated with seasonal movements remains elusive. By Mo...

Aves são importantes sentinelas, sensíveis à contaminação ambiental. Chumbo (Pb) e cádmio (Cd), elementos-traço não essenciais, podem causar impactos biológicos negativos, como efeitos neurológicos e reprodutivos e até morte. Este estudo avaliou concentrações de Pb e Cd em tecidos da garça-branca-grande (Ardea alba) e do colhereiro (Platalea ajaja)...
Data
Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morpho- logical variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological d...

Niche theory predicts that sympatric species should differ in some ecological characteristic, to allow co-existence and reduce competition for key resources. Food is critical on wintering grounds and stopover areas for migratory species that need to accumulate reserves in order to complete their migration. Wetlands of the Rio Grande do Sul coastal...
Conference Paper

As aves são um grupo com grande importância ecológica, pois possuem um papel fundamental na dinâmica de diversos ecossistemas. Conhecer a composição da avifauna de uma região é um passo fundamental para a conservação da biodiversidade, o que pode ser feito através de capturas com redes de neblina. Neste contexto, o presente estudo identificou a com...

Wading birds are key components of wetlands, transporting matter, energy, contaminants and associated organisms among limnetic, estuarine, terrestrial and coastal ecosystems. The role of cocoi herons (Ardea cocoi) in connecting these ecosystems was studied in the only known estuarine and limnetic colonies in coastal plains of southern Brazil. Food...

Mass strandings of seabirds occur frequently on many beaches worldwide and commonly involve penguins, petrels, shearwaters, and prions, among others. Large numbers of stranded albatrosses are rarely reported. In this paper, an unusual stranding event that involved five species of Procellariiformes, predominantly the Atlantic Yellow-nosed Albatross...
