1. Morphophysiological adjustments to shade of jaboticaba tree saplings
ABSTRACT We aimed to verify the morphophysiological changes in jaboticaba tree (Plinia peruviana (Poir.) Govaerts) saplings under shade gradient to improve knowledge on the appropriate light environmental conditions for the saplings production and field homogeneous or intercropping cultivation of this species. The saplings were grown under full sun and artif

2. The aquatic species Pontederia azurea and P. crassipes (Pontederiaceae) in the Pantanal, Brazil: evidence of how plant structure can simultaneously reflect phylogeny and ecology
ABSTRACT Hydric fluctuations in the Pantanal comprise annual dry and wet seasons that modify local diversity and plant morphology and anatomy. Widespread in this wetland are the sympatric Pontederia azurea and P. crassipes, which, although primarily aquatic, can also develop in non-flooded environments. This study undertook a comparative investigation of the

3. Caracteres importantes na identificação de espécies de Ludwigia (Onagraceae) ocorrentes no Recôncavo da Bahia, Brasil
Resumo Na flora aquática do Brasil, o gênero Ludwigia apresenta ca. 48 espécies. A maioria das espécies de Ludwigia é anfíbia, apresentando uma grande plasticidade fenotípica, o que torna sua identificação complexa. O objetivo deste trabalho foi realizar um levantamento taxonômico e analisar caracteres diagnósticos na delimitação das espécies d

4. Growth of radiata pine families in nursery and two years after field establishment
ABSTRACT: Pinus radiata D. Don is the most widely planted exotic species in Australia, Chile, New Zealand and Spain. In this study, growth and survival of P. radiata were compared in 30 open pollinated families grown under two contrasting watering regimes in nursery (well-watered cf. water-stress conditions) and planted on a drought-prone site with Mediterra

5. Ovarian development and spawning of Macrobrachium amazonicum (Crustacea, Decapoda)
RESUMO Das espécies nativas de camarões da América do Sul, Macrobrachium amazonicum (Heller, 1862) é a mais importante para fins de aquicultura, possuindo elevado valor comercial. Devido à sua importância, este estudo objetivou avaliar a plasticidade fenotípica de fêmeas da espécie em relação ao desenvolvimento gonadal, e determinar o tipo de deso

6. Phenotypic Plasticity of Pimenta pseudocaryophyllus (Gomes) Landrum Under Different Light Conditions
ABSTRACT The heterogeneous light pattern in forest environments leads to specific morphological and physiological responses. However, anthropogenic pressures in areas such as Atlantic Forest and Cerrado are modifying the light availability, and consequently the forest community composition. The aim of this study was to investigate the plasticity of forest sp

7. WATER AND LIGHT STRESSES DRIVE ACCLIMATION DURING THE ESTABLISHMENT OF A TIMBER TREE UNDER DIFFERENT INTENSITIES OF RAINFOREST CANOPY COVERAGE
ABSTRACT The loss of structure, diversity and functions in the rainforests makes it necessary to develop active strategies to restore their economic and ecological values. Planting selected species can help to catalyze ecosystem restoration. The capacity of the plants to survive and grow in the rainforests, where the canopy coverage changes stochastically, i

8. Reproductive biology of a viviparous lizard (Mabuya dorsivittata) from the subtropical Wet Chaco of Argentina: geographical variations in response to local environmental pressures
Herein we studied the reproductive biology of a viviparous lizard (Mabuya dorsivittata) from the Wet Chaco region (northeastern Argentina) and compared the results with other populations from the Espinal (central Argentina) and the Atlantic Forest (southeastern Brazil), and with other Neotropical species of Mabuya to better understand the possible causes of

9. Growth and reproduction in captivity unveils remarkable life-history plasticity in the smallnose fanskate, Sympterygia bonapartii (Chondrichthyes: Rajiformes)
ABSTRACT We analyzed growth and reproduction of captive-born smallnose fanskates Sympterygia bonapartii. Egg cases were obtained from oviposition of two females caught in the wild and held at Temaikèn Aquarium. Following hatching, growth was analyzed in 13 females and 21 males until sexual maturity. Pattern of oviposition activity and reproductive performan

10. Plant spatial arrangement affects grain production from branches and stem of soybean cultivars
ABSTRACT Phenotypic plasticity is the ability of plants to undergo changes in morphology and yield components to adapt themselves to distinct environmental conditions. The knowledge on the changes in yield components of branches and stems at varied plant spatial arrangements needs to be updated due to recent changes in soybean production system. Thus, this s

11. Reproductive traits and floral visitors of Aechmea distichantha plants growing in different habitats of a South American xerophytic forest
Abstract Aechmea distichantha, a widely-distributed facultative epiphytic bromeliad species, is present from rainforests to xerophytic forests. At its southernmost distribution (Humid Chaco) it grows in the understory and forest edges. This animal-pollinated bromeliad shows high phenotypic plasticity on its vegetative traits, but there is no information abou

12. Genetic diversity of a Paspalum notatum Flügge germplasm collection
ABSTRACT The objective of this study was to assess the genetic diversity among accessions of Paspalum notatum based on morphological marker traits and identify those morphological traits that contribute most to the variability among accessions. Fifty-three accessions were evaluated for the following traits: length, width, color, and pubescence of sheath; len
