Species composition, diversity, and vegetation structure in a gallery forest-cerrado sensu stricto transition zone in eastern Mato Grosso, Brazil

Foraging habitats as well as the tluctuations in vespid species' abundance in Mato Grosso State, Brazil, were deterrnined,t hrough sampling effon per hour per collector in four cerrado sensu lato habitats," campo úmido" (Cu)," campo sujo" (es), "cerrado sensu stricto" (Css), and "gallery forest" (Mg), during four periods consisting of two dry (August 1988 and June 1989) and two wet (October and December 1988) season periods. For "campo úmido", sorne species seern to be highly seasonal, either in the dry or wet seasons, whereas very few species occur year-round. The abundance, species composition and richness varied between habitats types and between seasons

Non-volant small mammals are organisms capable of yielding precise information on richness, abundance and species composition variations related to the use of habitats. The aim of this research was to compare these variations in Cerrado sensu stricto, Palm Forest, Gallery Forest and Rocky Field. From May 1999 to February 2000, we surveyed non-volant small mammals (hence small mammals) in Serra das Araras Ecological Station. We captured 218 individuals and recaptured 62 individuals, belonging to 21 taxa, 13 rodents and eight marsupials, in a total of 13200 trap-nights. Capture success was 1.7%. We observed higher richness of small mammals in forested areas (Gallery Forest and Palm Forest) than in open areas (Rocky Field and Cerrado sensu stricto). The Palm Forest had the highest richness of marsupials, possibly due to the quality of a specific niche. The Rocky Field had the smallest richness, but with very high abundance of few species, mainly Thrichomys pachyurus and Monodelphis domestica. Forest habitats had similar species composition. The open habitats, Cerrado sensu stricto and Rocky Field, had a distinct species composition between them, and also when compared to forested areas. Different species are exclusive or showed preference for specific habitats. The protection of horizontally heterogeneous biomes, such as Cerrado, has a fundamental importance to the maintenance of the regional diversity of the small mammal community of Central Brazil.

ABSTRACT The present study encompasses the species composition and ecological characteristics of the snake community in a Cerrado-Amazon transition zone in Midwest of Brazil (state of Mato Grosso). The data were collected during six excursions to the "Tanguro" (study area) by visual encounter survey, pitfall traps with drift fences and non-systematic sampling. We collected 194 specimens, distributed in 34 species, 26 genera, and eight families. The most abundant species were Crotalus durissus Linnaeus, 1758 (n = 50), Philodryas olfersii (Lichtenstein, 1823) (n = 15), Philodryas nattereri Steindachner, 1870 (n = 13), Xenodon rabdocephalus (Wied, 1824) (n = 12), Lachesis muta (Linnaeus, 1766) (n = 10) and Erythrolamprus almadensis (Wagler, 1824) (n = 10). The composition of species found here represents a combination of Cerrado and Amazonian savanna fauna.

Soil Level

The occurrence of cerrado (as tree and shrub savanna is called in Brazil) and forest formations side by side is common at the southern margin of the Brazilian Amazonian Forest, and previous studies have demonstrated the advance of forests over cerrado areas. The aim of the present study is to provide an accurate documentation of the transition process between the two major biomes. Tree data (≥ 5 cm diameter at 0.3 m above soil level) from three plots of cerrado sensu stricto lying near three of cerradão (the taller, denser form of cerrado) were inventoried starting in 2002 in an area of 1.5 ha made up of 150 subplots of 10 × 10 m (50 in each area). This showed that the most important species of the cerradão were invading areas previously occupied by smaller, lower forms of cerrado (although it is sometimes difficult to define which are ‘forest’ and which ‘cerrado’ species as many are flexible in size – for instance Emmotum nitens can often be intermediate, establishing in cerrado that develops into cerradão and on to forest). Some typical species such as Eriotheca gracilipes and Emmotum nitens, established since the first inventories, have increased their populations (between 27 and 210%). Tachigali vulgaris, a typical, weedy, adventive species of the Cerrado–Amazonian Forest transition, showed the largest increase in abundance in areas of cerrado sensu stricto (between 100 and 1200%), and is probably the most important pioneer species in the initial advance of the forest into cerrado at the Southern Amazonian border.

First Time

The state of Mato Grosso is the 3rd largest Brazilian state, is covered with three major Brazilian biomes, including the Pantanal, Cerrado, and Amazonia. To date, 449 ant species are recorded in literature for the state. In the present work, we documented the ants sampled along a fragmented landscape, in the municipality of Juara, in the Cerrado-Amazon transition zone in the state of Mato Grosso, Brazil. The ant species were captured with Pitfall traps installed in 20 trails with 10 traps in each (totaling 200). Our results show 151 species, belonging to 43 genera and eight subfamilies, of which 28 species were recorded for the first time in the state and five species recorded for the first time in Brazil. Most genera collected were Pheidole Westwood, 1839 (45 species) followed by Crematogaster Lund, 1831 (11 species). By highlighting species recorded for the first time in state of Mato Grosso and Brazil, we hope to encourage new discoveries and increase the general knowledge of the ant fauna of different biomes in the region.

Structural Types

Four structural types of cerrado vegetation were examined to test the following hypotheses: (1) there are predictable changes in woody plant density, species richness and life-history strategies from one structural type to another; and (2) plant species composition in the less-rich structural types represent particular and impoverished subsets of those found in the richer ones. The study was conducted at Fazenda Palmares (5°33′S, 42°37′W) Piauí State, Brazil. A 47% decrease in woody plant density between cerradão (forest) and the least-dense type of cerrado sensu stricto (scrub) was associated with a 40% decrease in species richness. The percentage of lower-layer species was reduced by 29% in the least dense type of cerrado sensu stricto compared to cerradão. The proportion of species that flower and fruit during the rainy season was also reduced by one third. Species were not distributed as impoverished subsets along the cerradão–cerrado sensu stricto gradient. It is argued that the reduction in woody plant density and richness is partly due to factors limiting the occurrence of species with particular life-history strategies. The species composition of structural types is affected by the ‘mass effect’ and also by surrounding biotas, which provide species that colonize particular types of cerrado vegetation. Both these processes reduce the likelihood that the species composition in the poorer structural types are simple subsets of those present in the richer types.

There are two regulations for mine reclamation success in the forestry area in Indonesia, namely Minister of Forestry Regulation No. P.60/Menhut-II/2009 and Minister of Energy and Mineral Resources Decree No. 1827.K/30/MEM/2018. Both regulations rule vegetation and soil success. This study aims to analyse criteria parameters from both regulations in the mine reclamation and compare them to the surrounding secondary natural forest (SNF). This study was conducted in 6 six types of mine reclamation stand structures: 1, 4, 6, 9, 11-year-old plantation and SNF using 1 hectare of the circular plot each (total 6 ha). Soil samples were collected from 40 cm depth to analyse physical, biological and chemical conditions. Mine reclamation areas had almost similar physical, biological and chemical soil conditions with SNF. Nevertheless, due to the potential acid-forming (PAF) material from overburden, the 1-year-old plantation had pH = 3.23-3.27. The highest diversity index and the number of species and families in all reclamation areas were H’ = 1.82 (11-year-old); 14 species (9-year-old); and 11 families (9-year-old), comparing with SNF were H’ = 3.48; 67 species, and 31 families. Conversely, vegetation structure parameters in mine reclamation areas were higher than SNF (diameter at height breast (DBH; 1.3 m) = 28.42 cm; tree density = 469/ha; basal area = 35.04 m2/ha; and total height = 16.85 m). Compared to the SNF, vegetation structure and soil conditions are mostly possible for mine reclamation success. Still, species composition needs to be considered further as a standard interval to meet the criteria.

Os efeitos de queimadas induzidas sobre a comunidade de abelhas Euglossini (Hymenoptera: Apidae) foram avaliados em floresta de transição entre o Cerrado e a Floresta Amazônica, no leste do Estado de Mato Grosso, Brasil. A riqueza, abundância e a composição de Euglossini foram determinadas em uma área controle não queimada (preservada), uma área queimada anualmente desde 2004 (degradação intermediária) e uma área queimada trienalmente desde 2004 (degradação elevada). Testamos a hipótese de que áreas com diferentes frequências de queimadas apresentam menor abundância de machos, menor riqueza e diferente composição de espécies de Euglossini em relação à área controle. As técnicas de coleta ativa e passiva de abelhas foram aplicadas usando seis substâncias puras para atração dos machos: β-ionona, benzoato de benzila, geraniol, fenil-etil-acetato, salicilato de metila e vanilina. Sete espécies foram catalogadas e não houve diferença nas abundâncias entre as três áreas amostradas (F (2, 12) = 0,150; p= 0,8). A riqueza estimada de espécies na área controle foi superior à área com fogo trienal (12 ± 3,8; 4 ± 2, respectivamente), enquanto a área com fogo anual apresentou riqueza intermediária (8 ± 4,35) e superior àquela da área com fogo trienal. A análise de UPGMA revelou diferença significativa quanto a composição de espécies da área de fogo trienal para as outras duas áreas. As queimadas anual e trienal reduziram a riqueza de espécies e alteraram a composição de espécies, com efeitos mais evidentes na área com fogo trienal, causando efeitos deletérios sobre a comunidade das abelhas das orquídeas. The effect of Fire on the Community of Euglossini (Hymenoptera: Apidae) in a Cerrado-Amazon Transitional Forest (Mato Grosso, Brazil) Abstract. We evaluated the effects of induced burned on Euglossini bee assemblages (Hymenoptera: Apidae) in a transitional area between Cerrado and Amazonia, eastern Mato Grosso, Brazil. We determinate abundances, richness and composition of Euglossini in three plots: control plot (unburned), plot burned each year since 2004 (intermediate degradation), plot burned each three years since 2004 (high degradation). We tested the hypothesis that two burned plots present lower male abundances, less species richness and different species composition in comparison with the control plot. We collected male bees actively and passively by using six pure fragrances: β-ionona, benzoato de benzila, geraniol, fenil-etil-acetato, salicilato de metila e vanilina. We collected seven species with no differences in male abundances among three plots (F (2, 12)= 0.150; p= 0.8). Estimated richness species in control the plot was higher than the plot burned each three years (12 ± 3.8; 4± 2, respectively), while plot burned each year showed intermediate richness (8 ± 4.35) and higher than plot burned each three years. Cluster Analysis (UPGMA) revealed significant differences in species composition of the triennial fire area to the other two areas. Our results suggest that fire occurring with different frequencies in transitional forest promote decreases in richness of species and modifications in species composition. These modifications were clearer in plot more degraded (burned each three years) and induce deleterious effects on orchid bee assemblage.
