Due to the rapid development of evolutionary genetic studies, specimens kept in biological collections over the centuries are now accessible for molecular analysis through the sequencing of so-called historical DNA. These data have been recovered from bones, skins, muscles, teeth, hair, feathers, and the exoskeleton of invertebrates belonging to specimens deposited in museums for years, i…
The Atlantic Forest is a hotspot, with high biodiversity levels and a high level of deforestation and degradation. The Pernambuco Centre of Endemism (PCE), originally distributed in northern São Francisco River, in the states of Paraíba, Alagoas, and Pernambuco is today the most endangered Atlantic Forest region and one of the most endangered ecosystems in the world, as only small and iso…
There are very few studies in northeastern Brazil, a region that is home to a variety of environments used to propose hypotheses and models of diversification, but have not had an empirical contribution to advance on these discussions, particularly with the contribution of molecular biology. In northeastern Brazil, forest refuges are result from processes of expansion and shrinkage of for…
The Lear's Macaw Anodorhynchus leari (Bonaparte, 1856), is currently listed as "Endangered" by IUCN and ICMBio. Is endemic to northeastern Brazil, with its area of occurrence inserted in the morphoclimatic domain of the Caatinga, and the population concentrated in the Raso da Catarina and Depressão Sertaneja Meridional ecoregions. It's a long-lived and monogamous species, with late sexual…
Primolius auricollis (Yellow-collared Macaw, Psittaciformes, Psittacidae) is a monotypic species of the Arinae subfamily, with records in many South American countries. In Brazil, it occurs mainly on the Cerrado, but with two distinct populations: the northern one, bordering the Tocantins and Araguaia rivers, through the north of the states of Mato Grosso, Tocantins, Goiás, and Pará; and …
An ecological process drawing attention from plant ecologists in the last years is the "recruitment limitation", this is, the incapacity of plants to occupy all available sites in the environment to recruitment of new individuals. Such limitation has profound implications to the structure and dynamics of plant populations and communities. Among the mechanisms involved in recruitment limit…

The brown-backed Parrot, Touit melanonotus (Wied-Neuwied, 1820) (Psittaciformes, Psittacidae), is one of the three endangered species of the Touit genus, which in turn comprises eight species. Considered as threatened with extinction in the "Vulnerable" category both in the list of the International Union for Conservation of Nature (IUCN) and in the list published by the Ministry of the E…
One of the ecological processes that has attracted the attention of plant ecologists in recent years is the recruitment limitation: the inability of plants to occupy all available places in the environment for the recruitment of new individuals. This limitation has profound implications for the structure and dynamics of plant populations and communities. The dispersion limitation is one o…
The genus Pyrrhura Bonaparte, 1856 is a monophyletic group of small parakeets that occurs in almost all forest formations of the Neotropical region. If on one hand the monophyletism of the genus is well supported by morphological, vocal and molecular characters, the alpha taxonomy of the group presents itself as one of the most complex and challenging amongst all parrots in the New World.…

Loss and fragmentation of native habitats are threats to mammalian diversity. In fragmented landscapes, species are affected by attributes at different spatial scales. Low population densities and loss of mammalian species in the Atlantic Forest (AF) are known to have negative effects on ecological interactions. Such effects may be more severe in the Northeastern portion of the AF, the Pe…
Most of the critical dynamics of forest regeneration occur at the earliest life history stages (seeds and seedlings), which affect plant recruitment. Recruitment limitation occurs when seeds do not arrive to the available places in the forest (seed limitation, including source and dispersal limitation), or do not find adequate conditions for seedling emergence and growth (establishment li…
Accurate species delimitation is essential to a wide range of biological subdisciplines. However, taxonomic knowledge has progressed slowly in the tropics compared to the temperate zone, generating a latitudinal taxonomy gradient with pernicious consequences for our understanding of biological diversity. To mitigate the effects of this artificial gradient, we are conducting an integrative…
Recently, there has been an expansion in using isotopic methodologies in ecological and ornithological studies. However, this methodology is still under-exploited in Brazil, raising the need for training scholars capable of applying this tool in the Brazilian ecological field. Isotopic tools have proven to be very efficient for monitoring and interpreting the effects of anthropogenic impa…
