Biodiversity Decline

Invasive species are the second cause of biodiversity decline in the world. Among the many invasive species, the Sus scrofa (wild boar) is amongst those that cause more impacts. Our aim was to report the presence of the wild boar in the last remaining open area of Cerrado in the São Paulo state, Brazil. In September 2007 an individual was seen and tracks were also observed during the same period at the Estação Ecológica de Itirapina.

Study Species

The blood parasites of 15,574 birds representing 266 species of 43 families from primarily three areas in São Paulo State, Brazil were examined for haematozoa. Only 1240 (8.0% of 121 species fo 32 families were infected with blood parasites. This prevalence was similar to that reported in a previous study. Species of Haemoproteus were the most commonly encountered haematozoans (38.9%), followed by microfilaria (30.7%), Trypanosoma (13.7%), Plasmodium (7.5%) and Leucocytozoon (0.8%). Prevalence of parasitism was significantly different between the three major areas sampled. It was shown that this was due in part to differences in the avifaunas at both the familial and species levels. Prevalence varied markedly in only one of the 10 years of the study. Monthly fluctuations in prevalence were largely due to changes in relative proportions of highlytion of both. Prevalences of both microfilaria and Trypanosoma were higher than reported for any other similar survey in the world.

Cadaverous entomofauna successions vary according to the region, environment, and climate, and such differences may occur within the same country due to seasonal variations. The present study aimed to analyze and compare the dipterofauna that visit or colonize carcasses in the urban and coastal areas of São Paulo, Brazil, during summer and winter seasons. Four swine (Sus scrofaLinné, 1758) carcasses of approximately 12 kg were used. The animals were previously euthanized and then placed in metal cages covered with a flight intercept trap (Shannon, modified). In total, 10,495 flies from 39 families were collected, with 15 species belonging to the Calliphoridae family, 14 species belonging to the Fanniidae family, 43 species belonging to the Muscidae family, and 22 species belonging to the Sarcophagidae family. Flies from these four families visited all carcasses; however, they did not show the highest visitation frequencies in all of the trials. Species variations occurred between the experiments that were performed at different locations and in different seasons. Furthermore, difference in the number of insects attracted to each stage of decomposition was observed. In addition to the four families highlighted above, the families Phoridae, Sepsidae, Otitidae, and Piophilidae were observed in all carcasses.

Unique Species

Brazil hosts the richest biodiversity of bioluminescent beetles in the world. Several species are found in the Atlantic rain forest, one of the richest and most threatened tropical forests in the world. We have catalogued the biodiversity of bioluminescent species mainly of Elateroidea superfamily occurring in one of the last largest and most preserved remnants of Atlantic rain forest, located at the Biological Station of Boracéia of São Paulo University (Salesopolis, SP, Brazil). This site accounted with the largest diversity ever found for a single place in São Paulo State, with 39 species: Lampyridae (30), Phengodidae (5), Elateridae (3) and Staphylinidae (1). This fauna has unique species that were not found in any other places of Atlantic forest in São Paulo state, especially fireflies from the Lampyrinae tribes (Cratomorphini, Lamprocerini, Lucidotini), the subfamilies Amydetinae and Photurinae, and the phengodids Pseudophengodes and Brasilocerus sp.2. Most species are found in dense Ombrophyl forest or at their border, and a few ones are found dwelling in the few open fields around the forest. There is a predominance of glowing patterns in the green region among forest inhabiting species when compared with open field fireflies.

The Chydorus and Pseudochydorus genera are widely distributed around the world. Some species of Chydorus are among the commonest anomopods and Pseudochydorus globosus, the only species of the genus, is believed cosmopolitan. This study was part of the project " Zooplanktonic biodiversity and state of degradation of continental water ecosystems in São Paulo State" , itself a part of the FAPESP/BIOTA Program - The Virtual Institute of Biodiversity (www.biotasp.org.br), the aim being to make an inventory and analyze the distribution of species of the genera Chydorus and Pseudochydorus in São Paulo State, Brazil. In total, 373 samples were collected from 223 water bodies in the Water Resources Management Units of São Paulo State, between 9/9/1999 and 8/28/2002. The sampled sites varied from small streams, rivers, ponds, lakes up to big reservoirs. Six species of the genus Chydorus and one of the genus Pseudochydorus were recorded. The most common and widely distributed species were Chydorus eurynotus and Chydorus pubescens. The species Chydorus parvireticulatus occurred only in one Water Resources Management Unit of the state, and constituted the first recorded of this species in São Paulo State.

AbstractBackgroundAt the beginning of 2020, SARS-CoV-2 spread to all continents, and since then, mutations have appeared in different regions of the world. The appearance of more virulent mutations leads to asseverate that they are also more transmissible. We analyzed the lower and higher virulent SARS-CoV-2 epidemics to establish a relationship between transmissibility and virulence based on a mathematical model.MethodsA compartmental mathematical model based on the CoViD-19 natural history encompassing the age-dependent fatality was applied to evaluate the SARS-CoV-2 transmissibility and virulence. The transmissibility was measured by the basic reproduction number R0 and the virulence by the proportion of asymptomatic individuals. The model parameters were fitted considering the observed data from São Paulo State.ResultsThe numbers of severe CoViD-19 and deaths are three times higher, but R0 is 25% lower in more virulent SARS-CoV-2 transmission than in a less virulent one. However, the number of more virulent SARS-CoV-2 transmitting individuals is 25% lower, mainly due to symptomatic individuals’ isolation, explaining the increased transmission in lower virulence.ConclusionsThe quarantine study in São Paulo State showed that the more virulent SARS-CoV-2 resulted in a higher number of fatalities but less transmissible than the less virulent one. One possible explanation for the number of deaths surpassing that predicted by the low virulent SARS-CoV-2 infection could be the transmission of more virulent variant(s).

Brazil is the country with the largest number of bioluminescent beetle species in the world. However, estimates suggest that this number could much be higher, since many species remain to be discovered. In this work we made a survey of the species of bioluminescent beetles in Serra de Paranapiacaba - the largest remnant of Atlantic Forest in São Paulo State. The survey was done at Intervales State Park, Carlos Botelho State Park and municipality of Tapiraí and the following species were collected: Aspisoma lineatum, Aspisoma physonotum, Aspisoma fenestrata, Cratomorphus besckey, Cratomorphus distinctus, Photinus penai, Photinus sp1, Photinus sp9, Ethra aff. malledicta or axilaris, Ethra aff. adicta , Lucidotini incertae sedis, Cladodes flabellicornis, Cladodes demoulini, Amydetes lucernuta, Bicellonycha sp8, Bicellonycha ornaticollis, Pyrogaster lunifer, Pyrogaster moestus, Pyrogaster sp2, Pyrogaster sp5, Pyrogaster sp6, Photuris lugubris, Photuris sp1, Photuris sp7, Stenophrixotrix sp1, Brasilocerus sp1, Pseudophengodes sp1, Hapsodrilus pyrotis, Hypsiophtalmus sp1, Ptesimopsia luculenta, Pyroptesis cincticollis, Pyrearinus brevicolis, Pyrearinus candelarius, Pyrearinus micatus, Pyrophorus divergens. Our data show that Serra de Paranapiacaba is the second richest area in São Paulo state, especially in elaterids, with unique species typical of this area and species common to other investigated sites such as the Biological Station of Boracéia (in Salesópolis county) and the urbanized areas in the between Campinas - Sorocaba- São Paulo, originally covered to the Atlantic Rainforest.

Rottboellia cochinchinensis is an aggressive invasive species native to Asia. This species is known worldwide for invading crops and disturbed habitats in tropical and subtropical regions. In Brazil, R. cochinchinensis had its southernmost record in São Paulo state; however, in this study we expand its distribution to Santa Catarina state, in the South Region of Brazil, based on the discovery of a population in Blumenau municipality. These new records are ca. 440 km distant from the nearest known population, in São Paulo municipality, São Paulo state, Brazil.

Home and public sea aquaria are becoming more and more popular worldwide. Aquaria species are selected for their aesthetic appeal in terms of color, shape or behavior. In Brazil, most species are imported from remote places, usually tropical areas around the world. Water discarded from aquaria often includes organisms, or their propagula, that may become locally established. There have been extensive discussions concerning the vectors of species dispersion from their native areas, which includes ornamental aquaria. In order to evaluate the potential of local aquaria as a source of non native macro algae, we surveyed sea-aquaria shops and exhibition aquaria in São Paulo State. Thirty eight species of seaweeds were isolated in the aquaria surveyed. Among them, six have not been recorded from Brazil and nineteen were not reported for São Paulo littoral, including Caulerpa scalpelliformis var. denticulata the only species that so far deserves being designated as invasive in Brazil. The present paper should alert environmental agencies and aquaria shops about the risk of involuntarily introducing non-native species through aquariophyly.
