Structure of the understory community in four stretches of Araucaria forest in the state of São Paulo, Brazil

We analyzed the structure of the understory community in the Atlantic Forest sensu lato, for which phytosociological descriptions of the understory are lacking. We delineated 50 plots of 10 × 20 m each at four sites within an Araucaria forest (a subtype of Atlantic Forest), located in the municipalities of Bananal, Campos do Jordão, Itaberá and Barra do Chapéu, all of which are in the state of São Paulo, Brazil. To sample the resident species of the understory, we randomly selected five 1 × 1 m subplots within each plot, resulting in a total sampling area of 250 m² at each site. We identified differences among the locations, mostly due to proportional differences in growth forms, in terms of species richness and the importance values within the community. Factors potentially influencing the understory structure include macroclimatic and microclimatic conditions, as well as forest fragmentation, the abundance of deciduous trees in the canopy, the surrounding vegetation and geographic location.

Análise temporal da heterogeneidade florística e estrutural em uma floresta ribeirinha

Neste trabalho, foram estudadas a composição florística e a estrutura fitossociológica da vegetação em um fragmento de floresta ribeirinha, ao longo do rio Passa Cinco, Ipeúna, SP. Foram amostradas 157 parcelas contínuas de 5 x 10 m, em uma área de 0,785 ha. Foram feitas medidas de diâmetro e mapeados todos os indivíduos com DAP maior ou igual a 5 cm, em 1989 e 1998. Constatou-se a presença de um mosaico vegetacional e discutiram-se os possíveis fatores definidores deste mosaico. Foram, também, verificadas as alterações florísticas e fitossociológicas na área após nove anos. As análises multivariadas da vegetação mostraram a presença de três grupos vegetacionais com grande sobreposição aos três tipos de solo identificados na área. As análises quantitativas da estrutura da comunidade mostraram diferenças em cada um destes grupos, que se mantiveram ao longo do tempo, indicando associações florísticas próprias com grande correlação à cada tipo de solo. O grupo vegetacional sobre solo aluvial, na faixa imediatamente paralela ao curso d’água, apresentou diferenças florísticas mais pronunciadas, e maior diversidade de espécies, área basal e densidade de indivíduos. Em nove anos, poucas alterações na estrutura fitossociológica foram observadas para as espécies de maior valor de importância na área, com um aumento de 2,01% do número total de indivíduos e 2,80% na área basal total.

Variações na composição florística e na estrutura fitossociológica de uma floresta ombrófila densa alto-montana na Serra da Mantiqueira, Monte Verde, MG

As florestas alto-montanas são reconhecidas por apresentarem composição florística e estrutura fitossociológica distintas das florestas em cotas altitudinais inferiores. Realizou-se um levantamento fitossociológico em uma floresta alto-montana localizada na Serra da Mantiqueira, distrito de Monte Verde, Camanducaia, Minas Gerais. O principal objetivo foi analisar o efeito do gradiente altitudinal na composição florística e na estrutura fitossociológica da vegetação. Foram instalados sete blocos paralelos com cinco parcelas contíguas de 10 × 10 m, distantes 50 m, entre 1.840 e 1.920 m de altitude. Todos os indivíduos arbóreos com CAP > 15 cm foram amostrados, assim como as "moitas de bambu" que continham no mínimo 10 perfilhos. Foram amostrados 1.191 indivíduos, pertencentes a 64 espécies arbóreas e duas espécies de bambu, distribuídas entre 42 gêneros e 26 famílias, além da classe de indivíduos mortos. A densidade total equivalente foi de 3.403 ind ha-1 e o índice de diversidade de Shannon-Wiener (H') foi de 3,284 nat ind-1. A biomassa morta destacou-se pelo elevado valor de importância (42,06), seguida de Pimenta pseudocaryophyllus (Gomes) Landrum (24,59), Roupala rhombifolia Mart. ex Meisn. (19,98) e Drimys brasiliensis Miers (18,57). Entre os parâmetros estruturais analisados a altura máxima do dossel e o número de indivíduos bifurcados estiveram correlacionados com a altitude. Uma considerável substituição de espécies foi observada, evidenciando um forte gradiente florístico, mesmo sendo o gradiente altitudinal amostrado relativamente curto.

Selection of potential probiotic lactic acid bacteria from fermented olives by in vitro tests

The present study aims to evaluate the probiotic potential of lactic acid bacteria (LAB) isolated from naturally fermented olives and select candidates to be used as probiotic starters for the improvement of the traditional fermentation process and the production of newly added value functional foods. Seventy one (71) lactic acid bacterial strains (17 Leuconostoc mesenteroides, 1 Ln. pseudomesenteroides, 13 Lactobacillus plantarum, 37 Lb. pentosus, 1 Lb. paraplantarum, and 2 Lb. paracasei subsp. paracasei) isolated from table olives were screened for their probiotic potential. Lb. rhamnosus GG and Lb. casei Shirota were used as reference strains. The in vitro tests included survival in simulated gastrointestinal tract conditions, antimicrobial activity (against Listeria monocytogenes, Salmonella Enteritidis, Escherichia coli O157:H7), Caco-2 surface adhesion, resistance to 9 antibiotics and haemolytic activity. Three (3) Lb. pentosus, 4 Lb. plantarum and 2 Lb. paracasei subsp. paracasei strains demonstrated the highest final population (>8 log cfu/ml) after 3 h of exposure at low pH. The majority of the tested strains were resistant to bile salts even after 4 h of exposure, while 5 Lb. plantarum and 7 Lb. pentosus strains exhibited partial bile salt hydrolase activity. None of the strains inhibited the growth of the pathogens tested. Variable efficiency to adhere to Caco-2 cells was observed. This was the same regarding strains' susceptibility towards different antibiotics. None of the strains exhibited β-haemolytic activity. As a whole, 4 strains of Lb. pentosus, 3 strains of Lb. plantarum and 2 strains of Lb. paracasei subsp. paracasei were found to possess desirable in vitro probiotic properties similar to or even better than the reference probiotic strains Lb. casei Shirota and Lb. rhamnosus GG. These strains are good candidates for further investigation both with in vivo studies to elucidate their potential health benefits and in olive fermentation processes to assess their technological performance as novel probiotic starters.

(Table 1) Tagging date, total length and sex of bowhead whales (Balaena mysticetus) tagged at Point Barrow, Alaska

Working with subsistence whale hunters, we tagged 19 mostly immature bowhead whales (Balaena mysticetus) with satellite-linked transmitters between May 2006 and September 2008 and documented their movements in the Chukchi Sea from late August through December. From Point Barrow, Alaska, most whales moved west through the Chukchi Sea between 71° and 74° N latitude; nine whales crossed in six to nine days. Three whales returned to Point Barrow for 13 to 33 days, two after traveling 300 km west and one after traveling ~725 km west to Wrangel Island, Russia; two then crossed the Chukchi Sea again while the other was the only whale to travel south along the Alaskan side of the Chukchi Sea. Seven whales spent from one to 21 days near Wrangel Island before moving south to northern Chukotka. Whales spent an average of 59 days following the Chukotka coast southeastward. Kernel density analysis identified Point Barrow, Wrangel Island, and the northern coast of Chukotka as areas of greater use by bowhead whales that might be important for feeding. All whales traveled through a potential petroleum development area at least once. Most whales crossed the development area in less than a week; however, one whale remained there for 30 days.
