Composición de la dieta del venado cola blanca (Odocoileus virginianus) en la región de la Cañada, Oaxaca. Colegio de Postgraduados
Vásquez Flores, Yasmit.
En México, el venado cola blanca (Odocoileus virginianus) es una de las principales especies cinegéticas. Este trabajo aporta información sobre la composición de la dieta del venado cola blanca mexicano para la región de la cañada, Oaxaca, México. La dieta de este ungulado se estimó usando análisis microhistológico de epidermis de plantas presentes en sus excretas. La recolecta de excretas y de plantas se realizó durante la época de seca y de lluvia del año 2011 a 2013. La dieta consistió de 83 especies vegetales de 36 familias botánicas; sin embargo, 10 especies representaron más del 50% de la dieta anual. Las especies más frecuentes en la dieta fueron Talinum paniculatum, Agave macrocantha, Euforbia sp., Karwinskia humboltiana, Zizipus pedumeulata, y...

Contrasting bee pollination in two co-occurring distylic species of Cordia (Cordiaceae, Boraginales) in the Brazilian semi-arid Caatinga: generalist in C. globosa vs. specialist in C. leucocephala Anais da ABC (AABC)
Machado,Isabel C.; Lopes,Ariadna V.; Sazima,Marlies.
In this study we compare the reproductive biology of Cordia globosa and C. leucocephala (Cordiaceae, Boraginales; formerly referred to Boraginaceae) to understand the functioning of the floral morphs and the relations with their effective pollinators. The species are synchronopatric, distylic, and self-incompatible. Though they share melittophilous traits, the main visitor and pollinator of C. globosa was the generalist and exotic bee Apis mellifera, while the only one of C. leucocephala was the oligoletic bee Ceblurgus longipalpis. These two latter species are restricted to the Caatinga of NE Brazil, contrasting with the wide distribution of Cordia globosa. While the fruit-set for C. globosa was high, independently if the pollen donor/stigma receptor was...

Do seedling functional groups reflect ecological strategies of woody plant species in Caatinga? Acta Botanica
Menezes,Tatiane Gomes Calaça; Rodal,Maria Jesus Nogueira; Lima,André Luiz Alves de; Lima,Lucivania Rodrigues; Pinto,Monalisa Alves Diniz S. C.; Melo,André Laurênio de.
ABSTRACT It is assumed that morphological traits of seedlings reflect different strategies in response to environmental conditions. The ecological significance of this has been widely documented in rainforests, where habitat structure and species interactions play an important role in community assembly. However, in seasonally dry ecosystems, where environmental filtering is expected to strongly influence community structure, this relationship is poorly understood. We investigated this relationship between functional groups of seedlings and life history traits and tested whether functional group predicts the ecological strategies employed by woody species to deal with the stressful conditions in seasonally dry ecosystems. Seedling functional groups, life...

Florística e fitossociologia de remanescentes de floresta estacional decidual em Piracicaba, São Paulo, Brasil Rev. Bras. Bot.
IVANAUSKAS,NATÁLIA MACEDO; RODRIGUES,RICARDO RIBEIRO.
O estudo foi realizado em dois remanescentes de floresta estacional decidual de 4 e 10 ha, em Piracicaba, São Paulo, Brasil. Esta floresta tem características abióticas próprias, como solo litólico, estresse hídrico no período seco e excesso de água no período úmido, definindo uma flora particular e fisionomia semelhante a de florestas secas. O levantamento florístico foi realizado nos dois remanescentes e o fitossociológico naquele de 10 ha, onde foram amostrados os indivíduos com perímetro à altura do peito (PAP) > ou = 15 cm existentes em 43 parcelas de 10 x 10 m. Foram registradas 110 espécies, 86 gêneros e 42 famílias. Do total de espécies, 20,7% continham espinhos, 31,0% dos 894 indivíduos amostrados apresentaram-se perfilhados e, no estrato...

Genesis and Classification of Soils Containing Carbonates in a Toposequence of the Bambuí Group Rev. Bras. Ciênc. Solo
Maranhão,Deyvid Diego Carvalho; Pereira,Marcos Gervasio; Collier,Leonardo Santos; Anjos,Lúcia Helena Cunha dos; Azevedo,Antonio Carlos; Cavassani,Rafael de Souza.
ABSTRACT The Bambuí Group, formed from siliciclastic sediments deposited on an extensive epicontinental platform at the end of the Neoproterozoic era, is characterized by limestones with fine to very fine texture. Limestone-derived soils in the southeast of Tocantins state, Brazil, are less notorious than similar soils in other regions of Brazil and their characterization could contribute to the Brazilian System for Soil Classification (SiBCS). Given that little is known of these soils, despitetheir agricultural potential, the objective of this study was to characterize their properties and the processes leading to soil of genesis, and also contribute to developing the Brazilian System of Soil Classification (SiBCS). Soils profiles were located on the...

Hawkmoth fauna (Sphingidae, Lepidoptera) in a semi-deciduous rainforest remnant: composition, temporal fluctuations, and new records for northeastern Brazil Anais da ABC (AABC)
PRIMO,LUIS M.; DUARTE,JOSÉ A.; MACHADO,ISABEL C..
We carried out a qualitative and quantitative inventory of the hawkmoth fauna (Sphingidae) of an area of semi-deciduous seasonal rainforest in the state of Pernambuco (Tapacurá Ecological Station), northeastern Brazil. Hawkmoths were sampled monthly from October 2004 to February 2007 (27 months). We recorded 31 species from 16 genera, three tribes, and three families. Macroglossinae was the most abundant subfamily and represented ca. 71% of all species. Out of the 277 individuals collected, 88.4% were males. Five new records were made for northeastern Brazil: Enyo gorgon (Cramer, 1777), Perigonia stulta (Herrich-Schäffer, [1854]), Eupyrrhoglossum sagra (Poey, 1832), Nyceryx coffaeae (Walker, 1856) and Xylophanes chiron (Drury, 1773). Eight further species...

HOW DO WE IDENTIFY MICRONYCTERIS (SCHIZONYCETRIS) SANBORNI SIMMONS, 1996 (CHIROPTERA, PHYLLOSTOMIDAE) RELIABLY AND WHERE WE CAN FIND THIS SPECIES IN BRAZIL? Pap. Avulsos de Zool. (São Paulo)
FEIJÓ,ANDERSON; ROCHA,PATRÍCIO ADRIANO DA; FERRARI,STEPHEN F..
Micronycteris is divided into four subgenera, Micronycteris, Leuconycteris, Xenoctenes, and Schizonycteris. The latter includes Micronycteris (Schizonycteris) minuta, Micronycteris (S.) schmidtorum, Micronycteris (S.) sanborni and Micronycteris (S.) yatesi. Little is known of the biology of M. (S.) sanborni, which is widely distributed in the dry forests of South America, but is known from only few sites. The scarcity of records of M. sanborni appears to be at least partly related to the difficulty of differentiating this species from the other members of the subgenus Schizonycteris. The present study identifies the key traits that distinguish this species from other Schizonycteris, reviews the geographic distribution of the species, and presents some...

Mammals of the Cosigüina Peninsula of Nicaragua Mastozool. neotrop.
Genoways,Hugh H.; Timm,Robert M..
Nicaragua's Cosigüina Peninsula, located at the northwestern tip of the country, is one of the most poorly studied biotic regions in Central America. The peninsula has been occupied for millennia because the climate of the region supported human habitation and because of its strategic position along the rich Pacific coast. The combination of long-term occupancy by humans and the cataclysmic eruptions of Volcán Cosigüina have produced a heavily impacted landscape. During the 1960s, the University of Kansas conducted multiyear field surveys of the terrestrial mammals on the peninsula and the adjacent mainland to quantify species diversity, relationships, abundances, habitat use, and reproduction. The mammalian fauna of the peninsula contains at least 39...

Species diversity and seasonal variation in the composition of a bat community in the semi-arid brazilian caatinga Biological Sciences
Rocha, Patrício Adriano da; Ruiz-Esparza, Juan; Ribeiro, Adauto Souza; Ferrari, Stephen.
 The caatinga scrublands are relatively poorly-studied, and few data are available on the biome’s chiropteran fauna. The present study focuses on the bat community of the arboreal caatinga of Serra da Guia. Bats were trapped in mist-nets on three new moon nights per month between October, 2008, and September, 2009. Atotal of 157 individuals were captured, representing 12 species. Species richness estimated by Jackknife1 was 14.8. Glossophaga soricina and Carollia perspicillata were by far the most common species, accounting for 56.7% of the specimens captured. Species diversity was 1.80, while equitability was 0.72. There was no significant seasonal difference in species diversity or evenness. However, the present study recorded a clear seasonal shift in...

The use of firewood for home consumption and the fabrication of hand-crafted ceramics in a semi-arid region of Northeast Brazil Acta Botanica
Silva,Mariana Cavalcanti Gomes da; Ramos,Marcelo Alves; Alves,Angelo Giuseppe Chaves.
ABSTRACT This study aimed to identify, analyze and compare different uses of firewood for home consumption and for handicraft work in rural communities in Altinho, Pernambuco, Brazil. Semi-structured and free-listing interviews were performed to catalog the plants that were better known by locals and that were mostly used as firewood for home consumption and handicraft work. Two in situ inventories were performed at the homes of the study location in order document the plants that were actually used. A total of 39 species of woody plants belonging to 16 botanical families were registered. The most widely-known species for both uses were also the species that were most used and preferably-used-as-wood by the population. The plants most...
