To understand the geographic distribution of visceral leishmaniasis (VL) in the state of Mato Grosso do Sul (MS), Brazil, both the climatic niches of Lutzomyia longipalpis and VL cases were analysed. Distributional data were obtained from 55 of the 79 counties of MS between 2003-2012. Ecological niche models (ENM) of Lu. longipalpis and VL cases were produced using the maximum entropy algorithm based on eight climatic variables. Lu. longipalpis showed a wide distribution in MS. The highest climatic suitability for Lu. longipalpis was observed in southern MS. Temperature seasonality and annual mean precipitation were the variables that most influenced these models. Two areas of high climatic suitability for the occurrence of VL cases were predicted: one near Aquidauana and another encompassing several municipalities in the southeast region of MS. As expected, a large overlap between the models for Lu. longipalpis and VL cases was detected. Northern and northwestern areas of MS were suitable for the occurrence of cases, but did not show high climatic suitability for Lu. longipalpis . ENM of vectors and human cases provided a greater understanding of the geographic distribution of VL in MS, which can be applied to the development of future surveillance strategies.

This study updates the geographic distributions of phlebotomine species in Central-West Brazil and analyses the climatic factors associated with their occurrence. The data were obtained from the entomology services of the state departments of health in Central-West Brazil, scientific collections and a literature review of articles from 1962-2014. Ecological niche models were produced for sandfly species with more than 20 occurrences using the Maxent algorithm and eight climate variables. In all, 2,803 phlebotomine records for 127 species were analysed. Nyssomyia whitmani, Evandromyia lenti and Lutzomyia longipalpis were the species with the greatest number of records and were present in all the biomes in Central-West Brazil. The models, which were produced for 34 species, indicated that the Cerrado areas in the central and western regions of Central-West Brazil were climatically more suitable to sandflies. The variables with the greatest influence on the models were the temperature in the coldest months and the temperature seasonality. The results show that phlebotomine species in Central-West Brazil have different geographical distribution patterns and that climate conditions in essentially the entire region favour the occurrence of at least one Leishmania vector species, highlighting the need to maintain or intensify vector control and surveillance strategies.

RESUMO -Há poucas informações sobre a composição fl orística das fl orestas estacionais em Mato Grosso do Sul. O objetivo deste trabalho foi atualizar o conhecimento sobre a composição fl orística das fl orestas estacionais do MS no Biota-MS. Foram utilizadas coletas de plantas lenhosas dos autores e de outros coletores em Florestas estacionais semidecíduas ou decíduas, ou em áreas de transição, depositadas nos herbários CGMS, COR e DDMS. Acrescentaram-se exemplares depositadas no herbário MBM e em alguns casos no herbário ESA coletadas no estado. Foram encontradas 497 espécies distribuídas em 69 famílias e 270 gêneros. As famílias mais ricas foram Leguminosae com 88 espécies, Euphorbiaceae (36 spp.), Myrtaceae (32 spp.), Malvaceae (25spp.), Rubiaceae (23 spp.), Moraceae (18 spp.), Rutaceae e Lauraceae (15spp.), Sapindaceae 14 spp.), Apocynaceae (12spp.) e Meliaceae (10spp.). Os gêneros mais ricos foram Ficus e Eugenia com 13 espécies, Mimosa, Cordia e Piper com nove, Croton e Bauhinia com oito, Aspidosperma, Zanthoxylum e Nectandra com sete espécies Palavras-chave: Leguminosae, mata seca, vegetação ABSTRACT -Woody fl ora of dry forests of Mato Grosso do Sul: state of the art. There is little information on the composition of seasonally dry tropical forests (SDTFs) in Mato Grosso do Sul, Brazil. This study aimed to update the knowledge of SDTFs of Mato Grosso do Sul, in the context of Biota-MS. We used Herbarium data (CGMS, COR and DDMS) of woody plants collected in deciduous and semideciduous forests, as well as transitional areas. Other records collected in Mato Grosso do Sul from the Herbarium MBM and, in some cases, from the Herbarium ESA were added. We compiled 497 species distributed in 69 botanical families and 270 genera. The richest families were Leguminosae with 88 species, Euphorbiaceae (36 spp.), Myrtaceae (32 spp.), Malvaceae (25 spp.), Rubiaceae (23 spp.), Moraceae (18 spp.), Rutaceae and Lauraceae (15 spp.), Sapindaceae (14 spp.), Apocynaceae (12 spp.) and Meliaceae (10 spp.). The richest genera were Ficus and Eugenia with 13 species, Mimosa, Cordia and Piper with nine, Croton and Bauhinia with eight, Aspidosperma, Zanthoxylum and Nectandra with seven species each.

RESUMO-O presente trabalho teve como objetivo caracterizar o cenário atual das coleções botânicas de Mato Grosso do Sul, buscando contribuir para o direcionamento de ações visando uma melhor documentação da fl ora do estado. Informações sobre o número de exsicatas depositadas nos herbários de Mato Grosso do Sul foram obtidas através de consulta direta aos seus respectivos curadores ou adquirido no banco de dados do Centro de Referência em Informação Ambiental (CRIA). Foram encontrados 150.360 exemplares coletados no Mato Grosso do Sul e um índice de 0,41 coletas/km² para o estado. Para que o Mato Grosso do Sul alcance apenas a média nacional de coletas seriam necessários aproximadamente 210.000 exemplares, cerca de 60.000 a mais do que já foi coletado. Torna-se imprescindível que sejam defi nidas estratégias, diretrizes e metas visando o fortalecimento e à modernização das coleções biológicas, bem como o conhecimento da fl ora sul-mato-grossense.
