2. Genetic diversity among Brazilian okra landraces detected by morphoagronomic and molecular descriptors
ABSTRACT. The conservation of okra landraces [Abelmoschus esculentus (L.) Moench] in gene banks is essential for the success of their use in breeding programmes. This study evaluated the genetic diversity among okra landraces in Brazil based on morphoagronomic descriptors and AFLP markers. We studied 30 accessions of the vegetable gene bank of the Universida

3. Development of a mulberry core collection originated in China to enhance germplasm conservation
Abstract China, origin of mulberry, has rich genetic resources usually. High expense, limited space and wavering environment of usually conservation in vivo poses dangerous situation for mulberry. The concept of core collection could takes priority for conservation of mulberry. In this study, 560 accessions were used with 40 morphological descriptors and str

4. Organography of greenhouse and field accessions of wild Arachisspecies (section Arachis)
ABSTRACT Peanut or groundnut (Arachis hypogaea L.) is a globally important oilseed crop, with important nutritional qualities, and a rich source of amino acids and protein. Another 80 species have been described in the genus Arachis, 64 of which are found in Brazil, and even though their morphology and agronomic traits remain largely unknown, they have been

5. Traditional Eastern Spanish varieties of tomato
Despite the importance of traditional varieties of tomato (Solanum lycopersicum L.) as sources of variation in breeding programs and varieties targeted to high-price quality markets that value their exceptional organoleptic quality, little is known regarding the structure of these materials at the morphological level. In this study, a collection of 166 popul

6. Propuesta de descriptores para Acca sellowiana (Berg.) Burret
The feijoa plants [Acca sellowiana (Berg.) Burret] is one of the most valued genetic resource plants underutilized from Uruguay and Brazil. This tree is endemic of a narrow area of South America, comprising the northeast of Uruguay and the south of Brazil. Beyond the fact that it has edible fruits, cultivation is limited to domestic scale or small orchards.

7. Environmental heterogeneity: Anuran diversity in homogeneous environments
The northwestern region of São Paulo was extensively deforested during the agricultural expansion in the last century and only small fragments of the original vegetation cover remained. In this study, we investigated how habitat features influence the composition, richness, and diversity of anurans in environments homogenized by agricultural activities. We

8. PARÂMETROS GENÉTICOS POPULACIONAIS COMO INDICADORES DE SUSTENTABILIDADE EM POPULAÇÕES NATURAIS DE PIMENTA ROSA - Schinus terebinthifolius RADDI. (Anacardiaceae) NO BAIXO CURSO DO RIO SÃO FRANCISCO - SE/AL. / POPULATIONAL GENETIC PARAMETERS AS SUSTAINABILITY INDICATORS IN NATURAL POPULATIONS OF RED PEPPER Schinus terebinthifolius RADDI (Anacardiaceae), IN LOW SÃO FRANCISCO RIVER-SE/AL.
The conservation of forest species requires the prior knowledge of genetic parameters belonging to the population, to help to design strategies for this purpose. This study aimed to evaluate genetic parameters and suggest indicators of sustainability in populations of Schinus terebinthifolius Raddi. aiming the conservation and maintenance of diversity in thi

9. Biodiversidade e padrões de distribuição da anurofauna do Parque nacional das emas e entorno / Biodiversity and distribution patterns of frogs of the Emas National Park and surrounding
Composition and diversity of anuran amphibians in preserved and disturbed environments in the Cerrado of the State of Goiás, Mid-West Brazil. The Cerrado is the second largest biome of Brazil, with an approximate area of 2 million km, which represents about 23% of the total area of the country. Despite the high conversion of natural areas of the Cerrado in

10. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

11. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia / Physical, structural and floristic diversity of forest fragments in the upper basin of the Rio Araguaia
A região da alta bacia do rio Araguaia vem sendo objeto de profundas transformações relacionadas ao processo de ocupação rápida e intensa das terras a partir do final dos anos 70. Atualmente a paisagem nesta região, encontra-se completamente fragmenta. As ilhas de vegetação remanescentes, em sua maioria estão isoladas, cercadas por culturas agríco

12. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o
