1. Direct analysis of vicariance in Neotropical mayflies (Ephemeroptera)
Abstract: The distribution of aquatic insects has been poorly explored in quantitative analyses aiming at the historical reconstruction of area relationships in the Neotropics. Ephemeroptera is an ancient group, characterized by its low vagility, and of high richness and endemicity in this region. Systematic knowledge of the group has enormously increased in

2. Distribution of European and African species of genus Diaptomus (Copepoda: Calanoida: Diaptomidae): a track analysis
ABSTRACT The distributional patterns of 13 species of Diaptomus Westwood, 1836 were analyzed using the panbiogeographical method of track analysis. Locality records were compiled from the literature and mapped for the construction of individual tracks for each species. These tracks were superimposed to find the generalized tracks. Four generalized tracks wer

3. Subspecies of Hypolepis rugosula (Dennstaedtiaceae; Pteridophyta) around the world: morphological and biogeographic perspectives
The "Hypolepis rugosula complex" has been the subject of great debate among pteridologists: some have considered H. rugosula a single subcosmopolitan (or circum-Antarctic) species, whereas others have considered it a species-complex, encompassing several species. In the 1920s and 1930s, four geographically distinct varietiesof H. rugosula were recognized. In

4. Estudo das populações de flebotomíneos transmissores de Leishmania no Panamá / Study of sand fly population transmitter of Leishmania in Panam
The sand flies are insects of the order Diptera (nematocera), family Psychodidae, subfamily Phlebotominae that are recognized as important disease vectors. They are known to be vectors of arbovirus belonging to the family Reoviridae, Bunyaviridae and Rhabdoviridae as well as vectors of bacteria of family Bartonellacea. However, sand flies gained more epidemi

5. Biogeography on the early distribution of cuckoos (Aves: Cuculiformes)
Cuckoos are widely distributed, but are concentrated in the tropics, where they occupy a wide range of habitats. Both terrestrial and arboreal behaviors can be found in this group, but there is no consensus on as to whether these behaviors have arisen more than once. Moreover, the historical distribution of cuckoos is poorly understood. This paper presents a

6. Testing the Rio Doce as a riverine barrier in shaping the Atlantic rainforest population divergence in the rodent Akodon cursor
Akodon cursor occurs in dense rainforest from northern (8º S) to southern (26º S) states along the Atlantic coast of Brazil. Previous karyological and molecular data revealed two major clades, one including northern (8-15º S) and the other southern (19-26º S) populations. The center of geographic distribution (15-20º S), which included the state of Esp�

7. Ecological niche models and patterns of richness and endemism of the southern Andean genus Eurymetopum (Coleoptera, Cleridae)
Eurymetopum is an Andean clerid genus with 22 species. We modeled the ecological niches of 19 species with Maxent and used them as potential distributional maps to identify patterns of richness and endemicity. All modeled species maps were overlapped in a single map in order to determine richness. We performed an optimality analysis with NDM/VNDM in a grid o

8. Análise da hipótese da vicariância entre Dalbergia nigra Allem. ex Benth. e Dalbergia miscolobium Benth. (Fabaceae) com base em DNA cloroplastídico / Analysis of vicariance hypothesis between Dalbergia nigra Allem. ex Benth. and Dalbergia miscolobium Benth. (Fabaceae) based on chloroplast DNA sequences
O gênero Dalbergia L. f. (Fabaceae: Papilionoideae), possui cerca de 100 espécies de distribuição pantropical. No Brasil, há 40 espécies de Dalbergia distribuídas em áreas representativas dos diferentes ecossistemas brasileiros. D. nigra e D. miscolobium são espécies consideradas vicariantes, que ocorrem na Mata Atlântica e no Cerrado, respectivam

9. Systematic and Historical Biogeography of Conopophagidae (Aves: Passeriformes): Speciation in South American forests / Sistemática e biogeografia histórica da família Conopophagidae (Aves: Passeriformes): especiação nas florestas da América do Sul
In order to identify the historical processes of diversification of the gender textitConopophaga in South America, especially in the Atlantic forest, methods of phylogenetic and phylogeography inference were used in the present thesis. The genus phylogeny and the phylogeographic structure of two species ( textitConopophaga lineata and textitC. melanops) whic

10. Historical Biogeography of a Clade of Liolaemus (Iguania: Liolaemidae) based on ancestral areas and dispersal-vicariance analysis (DIVA)
Ainda que tenham sido feito muitos estudos filogenéticos no gênero Liolaemus, os mesmos não são apropriados para uma análise biogeográfica, porque não possuem uma amostragem taxonômica adequada. Desenvolve-se neste trabalho, uma análise biogeográfica do grupo de L. chiliensis, que se diferencia das contribuições prévias por representar a todos o

11. Sistematica de Acosmium s.l. (Leguminosae, Papilionoideae, Sophoreae) e estudos de morfologia de plantulas e numeros cromossomicos
Acosmium Schott (Leguminosae, Papilionoideae, Sophoreae) is a neotropical genus comprising 18 species. In the last revision of the genus four sections were recognized by Yakovlev, distinguished by the ratio between the length ofthe calyx teeth with the length of the calyx tube, curvature of radic1e and stamens number. The general aim of this thesis was to ev

12. Meliponini neotropicais: o gênero Partamona Schwarz, 1939 (Hymenoptera, Apidae, Apinae) - bionomia e biogeografia
This work, dedicated to the study of nesting habits of the species of the Neotropical genus Partamona Schwarz, is a sequence to the taxonomic revision recently published elsewhere. A total of 214 nests and nest aggregations of 18 species [Partamona epiphytophila Pedro & Camargo, 2003; P. testacea (Klug, 1807); P. mourei Camargo, 1980; P. vicina Camargo, 1980
