“…Small populations of savanna birds, including many of the taxa sampled in this study, occur in isolated Amazonian open vegetation enclaves, such as the BX-044 polygon in the Brazilian states of Rondônia and Amazonas (Aleixo & Poletto, 2007), the campinas of the lower Rio Tocantins (Lees et al, 2014), and the Alter do Chão savannas (Sanaiotti & Cintra, 2001). Although these enclaves may have been once part of a more extensive savanna landscape, several savanna species appear to quickly colonize recently deforested regions of the Amazon region, including the interior of the Basin far away from other open habitats (Borges et al, 2017;Guilherme & Czaban, 2015;Guimarães et al, 2016;Rutt et al, 2019;Sick, 1997;Vasconcelos et al, 2007).…”

“…Alternatively, they may be caused by the recent incursion of 'alien' haplotypes through deforestation, which may be especially true in some highly dispersive species (Guilherme & Czaban, 2015;Guimarães et al, 2016). If this holds true, deforestation not only leads to disappearance of forest diversity (Ferraz et al, 2007), but may also lead to secondary contact, gene flow, and possible genetic homogenization of previously isolated savanna bird populations (Rutt et al, 2019).…”

Aim: Neotropical savanna birds occur north and south of, but mostly not in the Amazon Basin, except for a few isolated savanna patches. Here, we investigate the phylogeography of 23 taxa of Neotropical savanna birds co-distributed across multiple isolated savanna patches to assess to what extent these species have a shared history of spatial diversification. We explore the role of the forested Amazon Basin as a vicariant barrier separating northern and southern populations, particularly focusing on the role of the coastal savannas of Amapá as a potential corridor of gene flow between northern and southern populations. Location: Neotropical savannas. Taxon: Aves. Method: We employ 775 mtDNA samples of 24 co-distributed savanna bird taxa from all major savanna patches in South America to infer phylogeographic patterns. For this | 1125 van ELS Et aL. B I OS K E TCH Paul van Els focuses mainly on the ecology and evolution of Neotropical birds, particularly birds of grass-dominated ecosystems. He is especially interested in the timing and spatiality of diversification of this group in relation to the vicariant events that shaped the South American savannas and to the life history characteristics inherent to a life in open habitats with a high degree of seasonal climatic variation. Author Contributions: PVE conceived the research idea and performed most sequencing, analysis, and writing. EZ aligned UCE data, LRM performed UCE-based analyses, VGB provided samples of Tyrannus savana, AS, AA, CCR, PSDR, and MPDS provided samples of Formicivora grisea, Neopelma pallescens, and Schistochlamys melanops, KZ, ROP, and JB provided samples of Emberizoides herbicola, Tyrannus albogularis, Sporophila plumbea, and Chordeiles pusillus. All reviewed the manuscript.

“…As espécies chamadas de "invasoras" são aquelas oriundas de outros biomas, como por exemplo, o cerrado ou o pantanal. Nas últimas décadas, estas espécies vêm expandindo sua área de ocorrência em direção ao norte, na região do bioma Amazônia, ocupando áreas antes florestadas, mas que agora estão cobertas por pastagens (GUILHERME; CZABAN, 2015), ou seja, são espécies que estão se beneficiando do desmatamento provocado pela ação humana. Dentre as espécies "invasoras" identificadas na APA Lago do Amapá estão a coruja-buraqueira (Athene cunicularia); o carcará (Caracara plancus) e o quero-quero (Vanellus chilensis; Anexo 1).…”

This text presents a historical and contextual narrative about the formation and changes that occurred in a large territorial area located in the Lower Acre River Valley, which in the early twentieth century was near Vila Rio Branco, the administrative headquarters of the then Department of Alto Acre. This administrative department was one of three such entities established by the Brazilian government in 1904, shortly after the official incorporation of Acre State at the end of 1903, when the country signed the Treaty of Petrópolis with Bolivia. The area in question, in the face of colonization and extractive occupation processes occurring in the late nineteenth century, first evolved as a rubber plantation and then underwent fragmentation and acquired agricultural function, in conjunction with the extractive exploitation that had been waning in strength in the decades following the 1910s. This land use began to undergo significant changes in the mid-1940s, marked by new forms of territorial occupation and diversified exploitation activities of the former Amapá rubber plantation. The area acquired multiple uses (extraction, hunting, fishing, agricultural production, leisure, environmental preservation, housing, and commercial activities), facilitating the emergence of new territorialities throughout the twentieth and twenty-first centuries, reinforced by changes in land ownership (territorial fragmentation by lease, inheritance sharing, sale, occupation, and expropriation). Nowadays, this geographical area that corresponded to the former rubber plantation known as Amapá is largely territorialized and still carries its old name. The rubber plantation, however, is now referred to by multifaceted nomenclatures, such as colônias do/no Amapá, bairro do Amapá, praia do Amapá, areal do Amapá, APA do Amapá, Lago do Amapá. These examples demonstrate the dynamic discursive forms that serve to name changes of geographical, historical, environmental, and economic nature experienced by the area in just over a century. The referential name is the same, but the meanings are different and loaded with stories.

“…(Sick 1997, Hoyo et al 2018). However; it has been gradually expanding its geographical distribution in Brazil; toward the north; occupying deforested areas in the Amazon along the major rivers and roads in the region (Guilherme & Czaban 2015). Regarding the diet; the Southern Caracara is an opportunistic/generalist species (Sazima 2007, Bierregaard & Marks 2018.…”

The Southern Caracara (Caracara plancus) is a South American falconid that over the years has been colonizing open areas of the Southwestern Amazon. Regarding food habits, it is considered an opportunistic/generalist species. Caracara plancus has a varied diet, composed of animal protein, including carcasses. It also consumes plants, although this behavior appears less frequently in the scientific literature. Here we present a report of a Southern Caracara feeding on peach-palm fruits (Bactris gasipaes) in the rural area of Brasiléia, state of Acre, Brazil. The peach-palm tree is a common species, cultivated for obtaining heart of palm (“palmitos”) and fruits for consumption and regional marketing. Besides being a new food item in the Southern Caracara diet, the observed behavior indicates that C. plancus can potentially become a plague to the regional culture of peach-palm.
