Abstract A major barrier to advancing ornithology is the systemic exclusion of professionals from Global South. recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed long-standing pattern highlighting individuals, knowledge, views North, while largely omitting perspectives people based within Neotropics. Here, we review current strengths opportunities practice ornithology. Further, discuss problems with assessing state...
Abstract Global-scope scientific journals have played an important role in upholding a colonial legacy of north-south inequities ornithology, and they now key to play increasing equity publishing. We explore common barriers faced by ornithologists the Neotropics (Latin America Caribbean) suggest priority actions that Ornithological Applications, Ornithology, other global-scope ornithological can take increase publication research uptake. Among most problems, we identified (1) restrictive...
Black-and-gold howler monkeys Alouatta caraya, are arboreal primates, inhabitants of Neotropical forests, highly susceptible to the yellow fever virus, considered early 'sentinels' outbreaks, and thus, major epidemiological importance. Currently, anthropogenic habitat loss modifications threatens their survival. Habitat modification can prevent, reduce or change dispersal behavior, which, in turn, may influence patterns gene flow. We explored past contemporary levels genetic diversity,...
Abstract Many ornithologists seek tools to work more equitably with people from historically marginalized and exploited groups. We developed a process promote collective construction of ornithological knowledge in the Special Feature series "Ecology conservation cavity nesters Neotropics'' for journals Ornithology Ornithological Applications. Colonialism produces systems that consecrate Eurocentric ideas dominant nations (including Canada, USA, countries western Europe) reinforce hierarchies...
The present study determined nuclear and mitochondrial (mtDNA) levels of genetic variability phylogeographic patterns in breeding populations Roseate Spoonbill (N = 57), Wood Stork 89), Jabiru 30), sampled the Brazilian Pantanal. These species were selected since they are bioindicators wetlands’ health threatened other parts their distribution. As close association with this ecosystem, appropriate for studying effects Pleistocene climatic changes on demographic patterns. Levels diversity...
The determination of genetic parameters for most waterbird populations presents considerable challenges because these species frequently breed in inaccessible locations which preclude capture nesting pairs. application non-invasive sampling techniques, such as the collection molted feathers field, could represent an appealing strategy to overcome above cited problem. Here, feasibility collected Brazilian Roseate Spoonbill (Platalea ajaja; N = 94) and jabiru Stork (Jabiru mycteria; 10)...
We review the effects of abiotic factors on body size in two grasshopper species with large geographical distributions: Dichroplus pratensis and D. vittatus , inhabiting Argentina diverse natural habitats. Geographical spans for both provide an opportunity to study changes size. The analyses distribution revealed a converse Bergmannian pattern: is positively correlated latitude, altitude, seasonality that influences time available development growth. Allen’s rule also inverted. Morphological...
Introduction: Integrating genetic data into conservation management decisions is a challenging task that requires strong partnerships between researchers and managers. Conservation in Latin America of crucial relevance worldwide given the high biodiversity levels presence hotspots this region. Methods: We conducted survey across to identify gaps opportunities aimed better understand managers’ points view how research could help practitioners achieve their goals, by implementing assessments...
DNA-based studies have demonstrated that avian genetic mating systems vary widely, with many species deviating from long-assumed monogamy by practicing extra-pair paternity and conspecific brood parasitism. Colonially breeding waterbirds provide interesting models in which to investigate this question because they show nesting habits proposed promote alternative reproductive strategies. However, little is known about the of group birds, mainly due difficulties obtaining data incubating...
ABSTRACT Behavioral observations made on fish have revealed remarkably diverse reproductive strategies, including polygamy by both sexes. Still, to date, most Neotropical species remain unstudied as whether the observed behavior in natural populations correlates with their genetic mating systems. Here, we investigated system of a wild population Prochilodus lineatus settled Middle Uruguay River basin. By using sibship reconstruction and parental inference methods based microsatellites’...

Hybrid zones are regions where genetically different populations meet and mate, resulting in offspring of mixed characteristics. In organisms with limited dispersal, such as melanopline grasshoppers, hybrid can occur at small spatial scales (i.e., <500 m). We assessed levels morphological, chromosomal, molecular variability adult males the grasshopper Dichroplus pratensis Bruner (N = 137 males, 188 females) collected 12 sites within a mosaic zone heterogeneous environment Sierra de la...

Here, we present systematic bibliographical synthesis exploring how the genetic been used avian populations in Neotropics. We searched international online databases for scientific publications, spanning from 2007 2017, describe trends and identify sample types used, species studied, questions addressed. analysis 21 articles showed that shed feathers were most frequently...
Abstract Waterbirds are increasingly affected by climate change and human disturbances to the wetlands on which they roost, forage breed. The evolutionary response of populations such changes is influenced genetic variability gene flow patterns, enable long‐term survival. Thus, monitoring waterbird can provide valuable information support conservation measures management policies for wetlands. This study assessed past contemporary levels diversity, estimated effective population sizes ( Ne )...
The present paper reviews the published information on mating systems and reproductive biology of Neotropical waterbirds. Thirty-four scientific articles were included, which divided into two main themes: “mating systems” (10 articles) “reproductive biology” (24 articles). Extra-pair copulation and/or fertilization reported to occur in 60% species investigated, while monogamy was 22%, bigamy 11% nest parasitism 11%. General aspects 30 more extensively reviewed, 20 seabirds 10 lacustrine...
In birds, the selection of nesting sites and mates has a profound influence on daily interactions individuals. Both behaviours are energetically costly time-consuming can strongly affect Darwinian fitness Using 12-year dataset banded returning breeders, we explored variables associated with nest-box choice mate in White-rumped Swallow, socially monogamous migratory passerine. Females reusing nest-boxes, but not males, produced significantly more fledglings than did those that changed...
Abstract The white‐faced ibis Plegadis chihi Vieillot, 1817 (Pelecaniformes: Threskiornithidae) is a socially monogamous colonially breeding bird in which behavioral and ecological observations suggest the occurrence of conspecific brood parasitism (CBP). We inferred aspects genetic mating system P. nature, using approach absence parental information. used five heterologous microsatellite loci multiple‐step methodological to infer kinship patterns among 104 pairs nestlings sampled inside 80...
We screened 44 heterologous microsatellites isolated in species of the families Threskiornithidae, Ciconiidae and Ardeidae for their use a migratory waterbird, white-faced ibis Plegadis chihi (Vieillot, 1817) (Threskiornithidae). Of loci, 57% amplified successfully 24% were polymorphic. In two breeding colonies from southern Brazil (N = 131) we detected 32 alleles (2-10 alleles/locus). Average He over all loci was 0.55, combined probability excluding false parents, 98%. There no departure...
