Spatial distribution of the litter carbon stock in the Cerrado biome in Minas Gerais state, Brazil

ABSTRACT Litter corresponds to the layer of decomposing dead organic matter present on the soil surface. This layer is very important for nutrient cycling and contributes with organic matter accumulation in the soil, besides the carbon stock. The objective herein was to quantify the carbon biomass, both content and stock, and map the litter C-stock in the Cerrado biome, which is formed by Savanna Grassland (SG), Cerrado Stricto Sensu (CE) and Forest Savanna (FS), in Minas Gerais state, southeastern Brazil. The data were collected in 26 fragments in Minas Gerais state, totaling 210 sampling locations. A variographic study was conducted and, for mapping, the ordinary kriging method was used for delimitation of homogeneous zones. It was possible to detect high variability in the carbon biomass, carbon content and C-stock in the Cerrado biome litter in Minas Gerais state. The carbon content presented lower variability, ranging from 40 to 44%, so that it is not responsible for explaining the variability of the litter C-stock. Savanna Grassland and Savanna Forest present, respectively, the lowest and highest C-stocks. C-stock presented a considerable spatial structure dependence, allowing to use the geostatistical procedures for mapping it in the Cerrado biome of the Minas Gerais state. The C-stock kriging map showed good accuracy, allowing to verify that the lowest C-stocks in the litter are found from the center to the northern of the Minas Gerais since the highest air temperatures are also verified in this direction.

Study Laboratory

This study aimed at quantifying carbon (C) and biomass stocks in shoot portion, leaf litter, roots and soil within a fragment of dense savanna 'cerradão', 158.5 ha in area, located in Minas Gerais state. Measures were quantified using dendrometric parameters obtained during the forest inventory and collection of leaf litter, root and soil samples. Furrows were dug in the soil each 100 cm long, 50 cm wide and 100 cm deep in order to collect root samples at depths of 0-30 cm, 30-50 cm and 50-100 cm, and soil samples from the layers 0-10 cm, 10-20 cm, 20-40 cm, 40-60 cm and 60-100 cm, as well as any leaf litter from the surrounding surface. Analyses were performed in the Organic Matter Study Laboratory (DCS/UFLA) to determine C contents in the above matrices, using an Elementar analyzer model Vario TOC Cube. Higher C contents and stocks and lower density were noted in topmost soil layers. In cerradão, shoot portion was found to be the matrix contributing the most to biomass production, followed by roots and leaf litter. Carbon stock in the fragment was 139.7 Mg ha-1. Soil was the matrix contributing the most to stocked C (64.8%), followed by the shoot portion (26.3%), roots (5.2%) and leaf litter (3.7%).

We present here the first record of Amphisbaena mertensi in Minas Gerais state, southeastern Brazil. Through analysis of scientific collections, we found specimens of A. mertensi from municipalities of Patos de Minas, Uberaba, Indianópolis, Uberlândia and Araguari, in Triângulo Mineiro and Alto Paranaíba regions. These localities are inserted in the Cerrado biome, with Atlantic Forest enclaves, and represent an expansion of the previously known geographic distribution for the species.

A New Species

Microvelia joceliae Magalhães & Moreira, sp. nov. is described and illustrated based on material from Parque Natural Municipal das Andorinhas, Minas Gerais State, in southeastern Brazil. The new species can be distinguished from congeners occurring in the region by the pronotum of the apterous form covering almost the entire thorax dorsally, proepisternum with black denticles, male abdominal segments V–VII ventrally depressed, shape of the asymmetrical parameres, and female abdominal laterotergites reflected over the mediotergites and almost touching over segments V–VII.

Nesting Behaviour

Mischocyttarus saussurei nests show a curious architectural pattern which could be related to colony camouflage. Since information on that species is scarce in literature, this study aimed to record ecological data on M. saussurei, as well as morphometric data on its nests. Data was collected at the Parque Estadual do Ibitipoca state park and at the municipalities of Barroso and Inconfidentes, Minas Gerais state, Southeastern Brazil. Seven colonies were located, exclusively in conserved environments. Five nests were dissected for morphometric analysis and for the assessment of the vegetal matter incorporated to comb walls. Nests showed comb cells opening towards the substrate and covered by vegetal layers, in which three families of mosses and three of liverworts could be identified. We deduct that the nests’ morphometry and the incorporation of vegetal layers to the combs are related to the camouflaging of colonies amidst their substrate.

The species has only two historical records in the state, both at areas formerly covered by Atlantic Forest. The finding raises the expectations for the maintenance of the species in the state, stressing the fact that this is the first species record in a Cerrado area in Eastern Brazilian states.

Important Site

The mammals of the Cerrado (Brazilian Savanna Biome) are still poorly known; only a few localities have been properly surveyed and studied. Hereby, we present a survey of the mammals of Serra do Cipó National Park, a protected area of Cerrado in Minas Gerais State, southeastern Brazil. A total of 55 species from eight orders were listed, which have been captured, observed or recorded in the literature. Some mammals are endemic or listed as threatened either by IUCN’s red list or by the national and regional red lists. Serra do Cipó National Park is an important site for scientific research and conservation of Minas Gerais’ biodiversity, though there is little information on mammal diversity and distribution in the park. We hope our study can help us fill this gap and improve the effectiveness of this national park in protecting Cerrado mammals and other vertebrates.

The Mean

The aims of this study were to evaluate the seasonal variation and frequency distribution of Rhipicephalus (Boophilus) microplus, Haematobia irritans, and Dermatobia hominis on crossbred heifers under field conditions in the northeast of Minas Gerais state, southeastern Brazil. From November 2007 to September 2009 (23 months), 40 heifers aged 16.6±2.4 months were divided into groups A (1/4 Holstein × 3/4 Gir) and B (1/2 Holstein × 1/2 Gir) and had the monthly infestation estimated along with the climatic conditions. The mean maximum and minimum temperatures were 28.5 and 19°C, respectively. The ectoparasites were present on animals in all months of the year. The levels of ticks on the animals were low (3.0±0.2 ticks/animal), with the highest density in midwinter. The temperature was the climatic factor that most influenced the tick levels. The population of H. irritans (13.9±0.3 flies/animal) and D. hominis (1.5±0.2 larvae/animal) on heifers was more influenced by rainfall and exhibited two population peaks during the year. 1/2 Holstein heifers harbored significantly more H. irritans and D. hominis than 1/4 Holstein heifers. The results are discussed considering the most appropriate periods to apply ectoparasiticides and the genetic make-up of the animals.

First Time

The objectives of this study were to identify anthophilous butterflies on psychophilous flowers of four Asteraceae species in an Atlantic Forest fragment in Viçosa, Minas Gerais State, Southeastern Brazil, and to determine whether there are species in common with other lepidopteran inventories of the Southeastern and Midwestern regions of Brazil. It is the first inventory of anthophilous butterflies of a semideciduous forest fragment in Zona da Mata, State of Minas Gerais. A total of 108 species were recorded, representing the fourth largest lepidopteran survey in this State. The results demonstrated that Asteraceae species may be important tools for monitoring anthophilous butterflies. The similarity with other inventories ranged from 1 to 92.55%. Fifteen species were reported for the first time in the State of Minas Gerais, and among them, Melanis alena and Thisbe irenea were observed in this study only.
