Floristic Survey

O presente trabalho tem por objetivo realizar um levantamento florístico das espécies nativas da caatinga do estado do Ceará, conhecendo também as espécies presentes nos municipíos pertencentes aos núcleos de desertificação Irauçuba, Inhamuns e Jaguaribe para melhor comprensão das espécies ainda existentes nessas áreas. Através de levantamento bibliográficos pôde se perceber o predomínio de espécies das Famílias Fabaceas, Euphorbiaceae, Cactaéceas, dentre outras. No geral, a caatinga cearense apresenta uma representatividade de espécies nativas que precisam ser conservadas. Torna-se clara a necessidade da criação de novas Unidades de Conservação em especial para as áreas das caatingas.

ABSTRACT Seeking to expand the floristic studies for the Atlantic rainforest, we herein present, based on field trips (January 2011 to April 2013) and herbarium records, a list of vascular plants found in the Mata do Junco Wildlife Refuge, State of Sergipe, Northeastern Brazil. We registered a total of 380 species, 244 genera and 80 families, with 45 new occurrences for the Atlantic rainforest of the State of Sergipe. The most representative families were Fabaceae (36 species), Cyperaceae (29) and Poaceae (28). Herbs were the most representative regarding habit (167 species or 44%). We found two threatened species: Caesalpinia echinata Lam. and Campylocentrum pernambucense Hoehne, both in the "endangered" category. Overall, the results indicate that the Mata do Junco Wildlife Refuge is floristically similar to other areas of Atlantic rainforest in the State of Sergipe. Moreover, the existence of new records and of a threatened native species reinforces its importance for conservation.

Lower Growth

In this study we verified data of water temperatures collected by CORSAN-RS from 1996 to 2004 in several cities of the state of Rio Grande do Sul, southern Brazil, and analyzed the possibility of raising the most cultivated fish species in Brazil. The water temperature from 1996 to 2004 was 16 to 28ºC in summer, 17 to 23ºC in fall, 14 to 17ºC (down to 9ºC in the coldest months) in winter and 14 to 21ºC in spring. Native species of this state, such as silver catfish (Rhamdia quelen), traíra (Hoplias malabaricus), dorado (Salminus brasiliensis), pintado (Pimelodus maculatus), as well as carps (family Cyprinidae), are resistant to the low winter temperatures. These species have a lower growth rate in coldest months (winter/spring) but a good development in warmer months (summer/fall), reaching a satisfactory performance throughout the year. In the periods of more intense cold, mortality of some introduced species, such as surubim from Amazon Basin (Pseudoplatystoma sp.), pirapitinga (Piaractus brachypomus), pirarucu (Arapaimas gigas), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and Nile tilapia (Oreochromis niloticus) may occur. In addition, as most tropical species have a thermal range for growth and reproduction between 20 to 28ºC, some species may have poor development even in fall. Therefore, water temperature in this state should be considered in the choice of fish species to be cultivated.

Serra da Pedra Branca (SPB) is a mountain range located in the Southwestern portion of the state Minas Gerais, in the municipality of Caldas (21°58′-21°55′S, 46°24′-46°22′W). It is a striking feature in the landscape, between 1100 and 1780 m.s.m., in a region that is part of the Atlantic Forest Domain and is considered as a priority area for conservation of the flora in Minas Gerais state. The vegetation is composed by a mosaic of “campo de altitude” (which occupy the greatest extension in the area), Seasonal Semidecidual Montane Forest, Dense Ombrophilous High-Montane Forest and Mixed Ombrophilous Forest. The aims of this study was the elaboration of a floristic survey of SPB added to the specimens collected by Anders Fredrik Regnell in the nineteenth century in Caldas and to analyze its floristic similarity with altitude areas of the Southeastern Region of Brazil. There were recorded 502 vascular plant species, distributed in 274 genera and 100 families. The majority of recorded species present herbaceous habit, terricolous, saxicolous and/or rupicolous (representing around 58% of recorded species), predominantly occurring in the “campo de altitude” (ca. 46%). The richest families were Polypodiaceae (20 spp.) and Dryopteridaceae (10 spp.) among the ferns, and Orchidaceae (56 spp.), Asteraceae (27 spp.) and Fabaceae (26 spp.) among the angiosperms. Just one species of gymnosperm was recorded, Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae). Five new records were made for the Minas Gerais flora, 13 species are cited as threatened with extinction in the state and at least six are endemic to SPB. Amongst 127 species collected in XIX century in the region, only 29 collected again, while 375 new records were made for SPB. The analysis of floristic similarity performed between the flora of SPB and other altitude areas of Southeastern Region revealed isolation of SPB in relation to other areas, highlighting its floristic peculiarity, which can probably be explained by its location in a distinct hydrographic basin. The vegetation of the SPB must be considered as endangered since the presence of endemic species and/or threatened species, associated with local environmental conditions suffering accelerated rate of destruction, highlight the need for urgent actions to preserve local biodiversity.

Giant Ragweed

The expansion of trade and economic relations with other countries increased the risk of importing new invasive types of weeds into the state. One of them is a serious danger weed — giant ragweed (Ambrosia trifida L.). This weed with high speed and aggressiveness inhabits and displacing native species in agricultural and non-arable land, including landscapes of big cities. A. trifida extends to non-arable lands with disturbed natural vegetation. This species is spreading through the contamination of seeds and agricultural equipment. It damaged soybeans, legumes and corn, as well as other grain crops. Increasing of this weed pollen in the air is a source of a massive disease with allergies. At present, there is danger of entry by this weed to Ukraine from neighboring countries.

We present an updated checklist of the amphibians and reptiles for the state of Guerrero, Mexico. This list is based on bibliographic records, the revision of scientific collections and the authors’ field notes. The herpetofauna of the state includes 259 species (78 amphibians, 181 reptiles), of which three are introduced. The conservation status of all native species was assessed using three independent systems (NOM-059, IUCN and EVS). Finally, the geographic distribution of amphibians and reptiles is discussed in the context of both the biogeographic provinces within the state and the influence of road location on specimen collection patterns.

Interactions between invader species and the local biota may lead to disequilibria in regional ecosystems. For such reason, the cultivation of nonnative species may be prohibited in specific regions, as a means of protecting native species. On the other hand, the question of whether a species is a bioinvader or not may not be straightforward. This is the case of the mollusc Perna perna, presently naturalized and widely distributed along Brazilian coast, from the Bay of Vitória, in the state of Espírito Santo (ES), to the state of Rio Grande do Sul (RS). Following previous works that explored the hypothesis that P. perna invaded the coast of Brazil at the colonial period, attached to slave ships, we discuss zooarchaeological data, radiocarbon dating, and molecular genetics analyses. Out of the 578 archeological shellmounds investigated, 542 (93.8%) had no records of P. perna. From the radiocarbon dating results, it is possible to infer that the presence of the two P. perna specimens from the Saquarema shellmound, in Rio de Janeiro, as well as the other shells from the top layer, is likely related to a recent occupation of the site in the colonial period, with a great probability of being from the XVII or XVIII centuries. Data on genetic population structure of P. perna along the Brazilian coast showed higher genetic identities between the African and the Brazilian populations than among the Brazilian populations, while haplotypic diversity shows a pattern which relates to trade routes of slaves (XVII and XVIII centuries) between Africa and Brazil. These data reinforce the argument that the appearance of P. perna along the Brazilian coast is due to invasion during historical time.

A new species of Bulbostylis (Cyperaceae), only known from the Brazilian Amazonian coast, is here described and illustrated. Bulbostylis litoreamazonicola was found growing over dunes, in seasonally flooded restinga vegetation, and in humid fields near the mangroves from the State of Pará, Northern Brazil. This is the fifth Brazilian-native species of Bulbostylis lacking a persistent stylopodium on the mature fruit. The new species is mainly characterized by its annual habit, simple anthelate inflorescences, densely hispid to hispidulous longitudinally ribbed scapes, pubescent glumes, and cordiform nutlets.

O objetivo deste trabalho foi avaliar a diversidade de espécies florestais nativas produzidas nos viveiros do estado do Rio de Janeiro. O levantamento e diagnóstico foram realizados durante os meses de fevereiro, março e abril de 2010, sendo incluídos os viveiros que produziam mudas de espécies florestais da Mata Atlântica. O trabalho de campo consistiu em visitas a 70 viveiros florestais, nos quais foi requerida a lista das espécies produzidas e realizada entrevista com o responsável, sendo preenchido um questionário englobando diversos temas relacionados à produção de mudas. Foram observadas 277 espécies florestais nativas da Mata Atlântica sendo produzidas nos viveiros, que, em média, trabalham com 56 espécies nativas. A diversidade total de espécies florestais da Mata Atlântica produzidas nos viveiros do Estado do Rio de Janeiro é baixa, assim como a diversidade média, já que mais da metade dos viveiros trabalha com uma listagem de 50 ou menos espécies, número insuficiente considerando a diversidade de espécies florestais presentes nas diferentes formações vegetais do estado.Palavras-chave: Mudas florestais; restauração florestal; Mata Atlântica. AbstractAssessment of diversity of native species produced in forest nurseries of Rio de Janeiro State. The objective of this paper was to evaluate the diversity of native species produced by nurseries in the State of Rio de Janeiro. The diagnostic and survey were conducted during the months of February, March and April of the year 2010, the research included all nurseries that produced seedlings of Atlantic Forest species. The fieldwork consisted of visits to the 70 surveyed nurseries, in which a list of the species produced in the nursery was requested and the seedling production manager was interviewed, filling in a questionnaire covering various topics related to seedlings production. We observed 277 forest species native from the Atlantic Forest produced in the nurseries. In average, the nurseries produce 56 different native species. The total diversity of native species produced in the State of Rio de Janeiro is low, as well as the mean diversity, since more than half of the nurseries work with a list of 50 or fewer species, what is insufficient considering the diversity of forest species that occur in the different vegetation types of the state.Keywords: Forest seedlings; forest restoration; Atlantic Forest.
