Dynamics Of Populations

The international literature does not provide much information about the incidence of species of mites in nectarine cultivars. The purpose of the present study was to determine diversity and dynamics of populations of mites and their interactions in different nectarine cultivars in the southwestern region of the State of São Paulo, Brazil. These mites were split into 15 families, 22 genders and 28 species. <em>Aculus fockeui </em>(Nalepa &amp; Trouessant) (Eriophyidae) was the most abundant species, with 90.2 % of the mites collected. The populations of <em>A. fockeui</em> displayed specific periods with greater number of individuals. Phytoseiidae showed the highest richness of species. <em>Ricoseius loxocheles</em> (De Leon) and <em>Euseius ho</em> (De Leon) were the most abundant predators. <em>Euseius ho </em>population showed a positive correlation with rainfall.

Abstract: This study focus on an inventory of the ichthyofauna of the Una river, a tributary of the Paraíba do Sul river, located in the region of Paraíba do Sul River Valley, in the State of São Paulo. Sampling was carried out in three sampling areas along the channel of the Una river between April 2016 and March 2017. For the collection of fish specimens, was used angling, fyke nets, cast nets, dragnets and hand nets. A total of 1.534 specimens were collected, which corresponds to five different orders, 14 families, 26 genera and thirty species. The study revealed that the most significant number of reported species are from the orders Siluriformes and Characiformes. The Characidae family was the most representative concerning the wealth of species and Astyanax aff. bimaculatus (two spot Astyanax | lambari-do-rabo-amarelo) was the species with the highest number of individuals captured. The freshwater ichthyofauna of the Una river is composed of eight species considered allochthonous and one exotic. Of the thirty species listed in this study, five are new records for the Paraíba do Sul river basin.

Effect of Fungicides on the Mite Fauna ofPrunus PersicaL. Cultivars in Presidente Prudente, SP, BrazilThe objective of this study was to characterize the diversity of phytophagous and predatory mites on peach cultivars either with or without fungicide treatment, in the city of Presidente Prudente, State of São Paulo, Brazil. In order to evaluate the effect of fungicides, leaf samples were colleted at random from treated and untreated plants of the Tropical, Aurora 1 and Aurora 2 cultivars, from June 2004 to February 2006. From the results obtained it can be concluded that: plants with or without treatment showed high populations of predatory mites, indicating that the treatments were innocuous on the mite populations. A diversified composition of the mite community was observed. The Phytoseiidae family had the highest richness in numbers and species of mites.Euseius citrifoliusandE. concordiswere the most abundant species. Plants with or without treatment had high abundances of predatory mites, with a predominance ofE. citrifolius.

Fifty one nests and 200 cells of Trypoxylon (Trypargilum) lactitarse were obtained from trap-nests (cut bamboo stems) in Santa Carlota Farm (in two habitats: Itaoca Section-IS and Santana Section-SS), Cajuru and on the São Paulo University Campus, Ribeirão Preto (RP), both in the State of São Paulo, Brazil. The prey (spiders) of 18 cells from IS, 38 from SS and 70 from RP were identified. Nesting most frequently occurred during the hot and wet seasons (September to April). T. lactitarse preyed upon representatives of ten spider families. Araneidae (96.6%) (orb-weaver spiders) were the most frequent. Eustala sp.1 was the most frequently collected species in the three habitats (31.6% in IS, 20.1% in SS and 48.7% in RP), followed by Acacesia hamata (19.5%) and Alpaida leucogramma (10%) in IS, by Parawixia audax (16%) and A. hamata (15.4%) in SS and by P. audax (17.9%) and Eustala sp.2 (12%) in RP. The sizes of the reproductive niches were significantly different. There was a positive correlation between reproductive niche width and evenness.

The Cerrado region still receives relatively little ornithological attention, although it is regarded as the only tropical savanna in the world considered to be a biodiversity hotspot. Cerradão is one of the least known and most deforested Cerrado physiognomies and few recent bird surveys have been conducted in these forests. In order to rescue bird records and complement the few existing inventories of this under-studied forest type in the state of São Paulo, we looked for published papers on birds of cerradão. Additionally we surveyed birds at a 314-ha cerradão remnant located in central São Paulo, Brazil, from September 2005-December 2006 using unlimited distance transect counts. Out of 95 investigations involving cerradão bird studies, only 17 (18%) investigations teased apart bird species recorded inside cerradão from those recorded in other physiognomies of Cerrado. Except for one study, no research found more than 64 species in this type of forest, a result shared within many regions from Brazil and Bolivia. Differences in species richness do not seem be related with levels of disturbance of landscape or fragment size. Considering all species recorded in cerradão in Brazil and Bolivia, a compilation of data accumulated 250 species in 36 families and 15 orders. In recent surveys at central São Paulo, we recorded 48 species in 20 families, including the Pale-bellied Tyrant-Manakin Neopelma pallescens, threatened in São Paulo, and the Helmeted Manakin Antilophia galeata, near threatened in the state and endemic to the Cerrado region. Among the most abundant species inside this fragment, none was considered to be neither threatened nor endemic.

Fifty five nests and 216 cells of Trpoxlon (Trypargilum) rogenhoferi were obtained from trap-nests (cut bamboo canes) in Santa Carlota Farm (Itaoca Section=IS and Santana Section=SS),Cajuru and on the Sao Paulo University Campus,Ribeirao Preto (=RP),both in the State of Sao Paulo,Brazil (Sept. 199: - Oct. 1995). The prey (spiders) of 40 cells from lS,58 from SS and 39 from RP were identified. The greatest nesting frequency occurred during the hot and wet season (September to April). T rogenhoferi preyed upon individuals of five spider families,with Araneidae (orb-weaver spiders) being the most frequent (99.6%). Alpaid af negr (58%) was the most fquently collected species in lS, followed by A. alto (24.8%); in SS (59.6%) and RP (64.7%) the most fequent species was A. veniliae, followed in SS by A. aff. negro (14.9%) and in RP by A. leucogramma (13.5%). The size of reproductive niches, H'=1.25 (IS),H'=1.30 (SS) and H'=1.29 (RP) were not significantly different. There was a positive correlation between the reproductive niche width (H') and evenness.

Following reports of two autochthonous cases of sylvatic yellow fever in the State of São Paulo, Brazil, in 2000, entomological surveys were conducted with the objective of verifying the occurrence of vector species in forest environments close to or associated with riparian areas located in the western and northwestern regions of the State. Culicidae were captured in 39 sites distributed in four regions. Haemagogus leucocelaenus and Aedes albopictus were the most abundant species and were captured in all the regions studied. H. leucocelaenus was the most abundant species in the municipalities of Santa Albertina and Ouroeste, where the two cases of sylvatic yellow fever had been reported. Mosquitoes from the janthinomys/capricornii group were only found at eight sites in the São José do Rio Preto region, while Sabethes chloropterus was found at one site in Ribeirão Preto. H. leucocelaenus showed its capacity to adapt to a secondary and degraded environment. Our results indicate a wide receptive area for yellow fever transmission in the State of São Paulo, with particular emphasis on the possibility of H. leucocelaenus being involved in the maintenance of this sylvatic focus of the disease.

Technological Advances

The almost instantaneous access to information provided by technological advances has revolutionized the behavior of people and of the classrooms too. Teachers had to adapt themselves to new technologies to maintain students interested and attentive to the discipline being taught. In this work, the behavior of the students of the 6th grade of elementary school II during class was observed. The school chosen is a public school in the State of São Paulo (Brazil). The research was based on data collection. The students were observed by being filmed during six months. The results showed that the students were interested in the classes and committed to the activities. The place that the student chooses to sit in the classroom influences the behavior of the teacher, because the more distant the teacher, the less he participates in the class.

This book is an ethnographic study of controversial sounds and noise control debates in Latin America’s most populous city. It discusses the politics of collective living by following several threads linking sound-making practices to governance issues. Rather than discussing sound within a self-enclosed “cultural” field, I examine it as a point of entry for analyzing the state. At the same time, rather than portraying the state as a self-enclosed “apparatus” with seemingly inexhaustible homogeneous power, I describe it as a collection of unstable (and often contradictory) sectors, personnel, strategies, discourses, documents, and agencies. My goal is to approach sound as an analytical category that allows us to access citizenship issues. As I show, environmental noise in São Paulo has been entangled in a wide range of debates, including public health, religious intolerance, crime control, urban planning, cultural rights, and economic growth. The book’s guiding question can be summarized as follows: how do sounds enter and leave the sphere of state control? I answer this question by examining a multifaceted process I define as “sound-politics.” The term refers to sounds as objects that are susceptible to state intervention through specific regulatory, disciplinary, and punishment mechanisms. Both “sound” and “politics” in “sound-politics” are nouns, with the hyphen serving as a bridge that expresses the instability that each concept inserts into the other.

Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.
