“…In Brazil, studies on bee fauna have been conducted across a diversity of habitats: the Atlantic Forest (Wilms et al 1996, Alvesdos-Santos 1999, Ramalho, 2004, the Cerrado (Pedro & Camargo 1991, Silveira & Campos 1995, Viana et al 1997, Andena et al 2005, the Caatinga (Carvalho & Marchini 1999, Zanella 2000, Zanella & Martins 2003, Lorenzon et al 2003, Aguiar & Zanella 2005, in sand dunes (Alves-dos- Santos 1999, Viana & Kleinert 2005, in the southern grasslands (Schlindwein 1998, Alves-dos-Santos 1999, Gonçalves & Melo 2005, Gonçalves et al 2009) and in transitional areas of the Cerrado-Amazonia (Santos et al 2004). Most of these records are concentrated in the eastern part of the country.…”

This is the first systematic survey of bees in the Pantanal wetland, Brazil. We recorded bee species and their floral resources within grassland and natural forest edge habitats in the Pantanal. Surveys were conducted during two to four-days per month, for a total of 12 months. Overall, we recorded 56 bee species visiting a total of 63 flowering plants. Asteraceae and Fabaceae presented the highest number of visited species, however Hyptis suaveolens (Lamiaceae) was the plant most visited by different bee species (18). The most generalist native bee was Trigona fuscipennis visiting a total of 17 flowering plant species. Apis mellifera , an exotic bee, visited 27 species. We also report the overlap (37.5%) in the use of floral resources between the exotic bee Apis mellifera and native bee species. Our updated bee checklist here presented includes 10 new records for the State of Mato Grosso do Sul. These data will support management strategies targeting the conservation of plant-pollinator interactions in the Pantanal ecosystem. Resumo: Esta é a primeira amostragem sistemática de abelhas realizada no Pantanal, Brasil. Nós coletamos espécies de abelhas bem como as plantas que utilizaram como recurso floral em áreas de pastagens naturais e bordas de áreas florestadas. As coletas foram conduzidas durante dois a quatro dias a cada mês, durante 12 meses. Foram registradas 56 espécies de abelhas visitando um total de 63 espécies de plantas. As famílias Asteraceae e Fabaceae apresentaram o maior numero de espécies visitadas, entretanto Hyptis suaveolens (Lamiaceae) foi a espécie visitada pelo maior número de espécies diferentes de abelhas (18). A abelha nativa mais generalista encontrada foi Trigona fuscipennis , que visitou 17 espécies de plantas. Apis mellifera , uma espécie exótica, visitou 27 espécies. Reportamos também a sobreposição (37,5%) no uso de recursos florais entre A. mellifera e espécies de abelhas nativas. A listagem de abelhas aqui apresentada inclui 10 espécies ainda não mencionadas para o estado de Mato Grosso do Sul. Esses dados apoiarão estratégias de manejo focadas na conservação das interações entre plantas e polinizadores no ecossistema Pantanal.

“…The herbaceous flora of the "caatinga" vegetation, however, is less well know, although previous studies have demonstrated that it: 1) retains the greater part of the biodiversity of the "caatinga" biome , Araújo 2003; 2) is composed predominantly of terophytes plants, and is therefore most apparent during the rainy season (Pereira et al 1989, Araújo 2003, Reis 2004, Silva 2004; 3) influences the dynamics of the woody vegetation component (Araújo 1998); 4) contains habitat-specific species (Reis 2004, Araújo et al 2005b; 5) flowers and fruits most intensely during the raining season, like the woody vegetation (Pereira et al 1989, Reis 2004, Silva 2004, Feitoza 2004) and 6) has great value as pasture, or for apiculture (Carvalho & Marchini 1999, Sampaio et al 2002, Lorenzon et al 2003. It has been suggested that the herbaceous vegetation has an important role in maintaining the biodiversity of the woody component of the flora, as their roots help maintain the soil seedbank (Araújo 2003, Feitoza 2004.…”

-(Inter-annual variations in the floristic and population structure of an herbaceous community of "caatinga" in Pernambuco, Brazil). The influence of climatic variations on the herbaceous component of the "caatinga" vegetation was examined in the state of Pernambuco, Brazil. A total of 105 1 × 1 m-plots were established, of which 35 were in a level micro-habitat, 35 in a riparian micro-habitat, and 35 in a stony microhabitat. During two consecutive years all herbaceous plants in these plots were counted, measured (height and diameter), and collected for identification. The Shannon-Wiener diversity index and the equitability were calculated for each year, as well as the density, frequency, dominance, total basal area and importance index for each species. The total annual pluviometric was 819.5 and 448.8 mm in 2002 and 2003, respectively. The herbaceous flora in the study area was composed of 71 species, of which 58 were sampled in the plots. The families with the greatest species richness were Malvaceae (8 species), Euphorbiaceae (7), Poaceae (6), Convolvulaceae (4), Fabaceae (4), and Portulacaceae (4). The diversity indices were 2.66 and 3.01 nats ind -1 in 2002 and 2003, respectively. The density, frequency, dominance and importance value of herbaceous populations, as well as, the height and diameter of plants were low in the dryer year. The riparian group was the most isolated of the microhabitats examined, both in terms of its floristic and its population structure. Annual seasonal climatic variations greatly modified these populations structure during the course of this study, emphasizing the fact that longterm studies are needed in order to better understand the dynamics of the herbaceous component of the "caatinga" vegetation.Key words -"caatinga", herbaceous component, phytosociology, seasonal climate changes, species richness RESUMO -(Variações interanuais na composição florística e estrutura das populações de uma comunidade herbácea da caatinga, Pernambuco, Brasil). Objetivou-se avaliar a influência das variações climáticas sobre o componente herbáceo em uma área de caatinga de Pernambuco. Foram estabelecidas 105 parcelas de 1 × 1 m, sendo 35 dispostas em micro-habitat plano, 35 em micro-habitat ciliar e 35 em micro-habitat rochoso. Durante dois anos consecutivos todas as ervas presentes nas parcelas foram contadas, medidas (altura e diâmetro) e coletadas para identificação taxonômica. Foram calculados o índice de diversidade Shannon-Wiener, a equabilidade e os parâmetros de densidade, freqüência, dominância, área basal total e índice de valor de importância. A precipitação pluviométrica anual registrada foi de 819,5 e 448,8 mm em 2002 e 2003, respectivamente. A flora herbácea registrada nas parcelas e fora delas foi representada por 71 espécies, sendo 58 amostradas. As famílias de maior riqueza de espécies foram Malvaceae (8), Euphorbiaceae (7), Poaceae (6), Convolvulaceae (4), Fabaceae (4) e Portulacaceae (4). As diversidades foram de 2,66 e 3,01 nats ind -1 em 2002 e 2003, respectivamente. ...

“…Segundo LORENZON et al (2003), as abelhas, ao coletarem recursos alimentares, se mantêm fiéis à determinada espécie vegetal até o esgotamento dessa fonte. Por essa razão, foi disponibilizado o substituto de pólen 15 dias antes da florada para que as abelhas iniciassem e mantivessem a coleta dessa dieta em detrimento do pólen do barbatimão, mesmo durante a sua floração.…”
