We surveyed social wasps (Polistinae) present in forest fragments of northwest of São Paulo state with different surroundings composed of a matrix of citrus crops and sugarcane in the expectation that the former matrix would be more diverse than the latter. We collected specimens actively using attractive liquids. We obtained 20 species in Magda, 13 in Bebedouro, 13 in Matão, and 19 in Barretos. The most common genus wasAgelaiain all of the areas. The greatest Shannon-Wiener index of diversity was obtained in Magda (H′=2.12). Species such asBrachygastra moebiana,Metapolybia docilis,Mischocyttarus ignotus,M. paulistanusandM. consimilishad not been recorded on recent surveys in the state. FurthermoreM. consimilisis a new record for the state. We concluded that, with our data, a relation between the occurrence of social wasps and the surrounding matrix was not detected.

The forest fragmentation is caused by natural or anthropic actions, which affect negatively the biota and the environmental services rendered by biological diversity. However, there is little information on the reflex of these actions in many different groups of animals, such as social wasps, which are abundant and significantly present in neotropical environments, causing a major impact in the communities they live due to their role in food webs. As their natural enemies, wasps are important in the control of agricultural plagues; in the natural environment, they are nectar collectors, frequent flower visitors, and potential pollinators of many species of plants. These factors justify studies which would evaluate in what way the forest fragmentation acts on these insects biodiversity. This study was carried out in four fragments, each of a different size, located in the municipalities of Inconfidentes and Ouro Fino, in the south of the state of Minas Gerais (Brazil), where the phytophysiognomy is the Montane Semideciduous Seasonal Forest. The research was carried out between December 2016 and March 2018, with the same sampling collection for each fragment, totalizing 104 sampling days. In total, 28 species and 51 colonies were recorded in the four areas and a greater richness for the greatest fragment (F4). The conclusion reached was that the size and heterogeneity of the fragment have an important role in maintaining the richness of social wasps.

Abstract A taxonomic treatment of the genera Turnera and Piriqueta in the state of Pernambuco, northeastern Brazil, is presented. Fourteen species of Turnera and six species of Piriqueta were found in the Atlantic Forest and Caatinga, of which nine are endemic to Brazil. Turnera pernambucensis is threatened and restricted to the Atlantic Forest of Pernambuco, while T. joelii is a new record for the state. The species predominate in steppe savanna and semideciduous seasonal forest, but several of them grow naturally in anthropized areas. Catimbau National Park is the locality with the highest species richness. Tristyly is recorded for the first time in Piriqueta guianensis. Identification keys, descriptions, illustrations, distribution maps, and comments about habitat, flowering, fruiting, and morphological relationships are provided.

In recent years, there has been increasing interest in matrix-type influence on forest fragments. Terrestrial amphibians are good bioindicators for this kind of research because of low vagility and high philopatry. This study compared richness, abundance, and species composition of terrestrial amphibians through pitfall traps in two sets of semideciduous seasonal forest fragments in southeastern Brazil, according to the predominant surrounding matrix (sugar cane and pasture). There were no differences in richness, but fragments surrounded by sugar cane had the lowest abundance of amphibians, whereas fragments surrounded by pastures had greater abundance. The most abundant species,Rhinella ornata, showed no biometric differences between fragment groups but like many other amphibians sampled showed very low numbers of individuals in fragments dominated by sugar cane fields. Our data indicate that the sugar cane matrix negatively influences the community of amphibians present in fragments surrounded by this type of land use.

We carried out a study on the anurofaunal community from an Atlantic Forest fragment (Monte Verde mountains) and the surrounding area in Cambuci municipality, Rio de Janeiro State, Brazil, which constitutes one of the largest fragments remaining in the largely deforested landscape of the northern portion of the State. We combined three sampling methods: plot sampling, transects and pit-fall traps. We recorded twenty species of amphibians, of which only eleven were found within the forest fragment (and five of these also occurred in the surrounding matrix). Two of the species recorded in the present study (Crossodactylus sp. and Ischnocnema cf. parva) may represent undescribed taxa. Our records expand the distribution range of one species (Scinax trapicheiroi) to the north, and fill a geographic distribution gap for another one (Ischnocnema oea). The estimated overall density of frogs living in the leaf litter of the fragment (based on results of plot sampling) was 3.1 individuals/100 m², with Haddadus binotatus being the most abundant species (2.4 individuals/100 m²). Comparisons of our data with those of other studies suggest that anuran communities in forest fragments ca. 1,000 ha or smaller may be severely limited in their richness, and often include a large proportion of species tolerant to open areas, such as many hylids. Our results show the importance of increasing knowledge about the anurofaunal community of the northern portion of the State of Rio de Janeiro and preserve the forest remnants that still exist in the region.

This study aimed to compare the mosquito fauna found in three remnant forest fragments of a semideciduous seasonal forest by using oviposition traps in the northwestern region of the state of Rio Grande do Sul, Brazil. Between 2018 and 2019, larvae were collected quarterly in three forest fragments, one situated in an urban area, another in a rural area close to the city and a third formed by an extensive area of native forest far from the urban environment. Four species were caught: Aedes terrens (Walker, 1856) (282), Limatus durhamii Theobald, 1901 (30), Aedes aegypti (Linnaeus, 1762) (23) and Toxorhynchites theobaldi (Dyar and Knab, 1906) (6). The Morisita-Horn index indicated a high similarity between the fragments studied (>80%). The mean number of mosquitoes collected. in the rural area was significantly higher than in the other areas (F = 6.073; d.f. = 17; p <0.05). The calculation of the phi coefficient to assess the co-occurrence of two species in the same trap did not indicate significant values (p> 0.05). Aedes terrens demonstrated a good ability to colonize and inhabit the different types of forest fragments studied. In addition, the forest fragment located in a rural area close to the urban area offered conditions for the survival of species of wild and urban mosquitoes, such as Ae. aegypti.

Apodanthaceae are achlorophyllous herbs holoparasitic on the stems and roots of species of Fabaceae or Salicaceae (Casearia and Xylosma). The family consists of two genera, Apodanthes Poit. and Pilostyles Guill. Although one species of each genus occurs in several states of Brazil, we report a new record of Pilostyles blanchetti (Gardner) R.Br. in the state of São Paulo, the first in 50 years. Comments on the distribution of species, hypothetic pollinators, and color images are presented.
