1. Estimating leaf area of basil cultivars through linear dimensions of leaves
ABSTRACT Ocimum basilicum L. (basil) is an annual herb belonging to the Lamiaceae family that has economic importance for many regions around the world. Thus, ecophysiological studies are needed to assess this species growth and dispersal. This work aimed to obtain equations from regression models that meaningfully estimate the leaf area of basil cultivars u

2. Genome-Wide Assessment of Putative Superoxide Dismutases in Unicellular and Filamentous Cyanobacteria
Abstract Cyanobacteria are photoautotrophic prokaryotes capable to grow in diverse ecological habitats, originated 2.5-3.5 billion years ago and were first to produce oxygen. Since then superoxide dismutases (SOD) acquired great significance due to their ability to catalyze detoxification of byproducts of oxygenic photosynthesis i.e. superoxide radicals. In

3. Impact of immunological state on eco-physiological variables in one of the southernmost lizards in the world
Abstract: The immune state is an essential component of survival as it directly influences physiological performance and health status. Variation in the leukocyte profile, a significantly increase in body temperature, and a detriment of the eco-physiological performance are among the possible consequences of an unhealthy state. In this study we analyse and

4. Changes in carbohydrates accumulation in Viguiera discolor Baker in response to water deficit
RESUMO O estresse hídrico é um fator ambiental que pode regular o crescimento, limitando a produção e levando a alterações fisiológicas e bioquímicas. Plantas apresentam uma série de respostas adaptativas a seca, tal como ajustamento osmótico, nos quais os carboidratos desempenham um importante papel. Avaliamos a influência do déficit hídrico no

5. Evapotranspiration and water sensitivity of Amazonian yellow ipe seedlings under different shading conditions
RESUMO A falta de informações técnicas sobre as exigências agroclimáticas e ecofisiológicas de espécies florestais, principalmente na fase inicial, limitam a produção de mudas de qualidade, o planejamento e a otimização de viveiros. Determinou-se a evapotranspiração, coeficientes de cultivo (kc) e os fatores de sensibilidade hídrica (ky) de mud

6. Phytochemical Profile of Pasture Weeds from the Brazilian Cerrado
RESUMO: A grande diversidade de espécies vegetais nas pastagens do cerrado brasileiro com características ecofisilógicas diferenciadas indica a possibilidade de encontrar no conteúdo celular dessa flora compostos químicos com potencial para uso na agricultura, saúde humana e animal. Para comprovação dessa hipótese, serão necessárias três etapas:

7. Biometric and Physiological Responses to Water Restriction in Moringa oleifera Seedlings
ABSTRACT A water deficit in the soil can cause water stress in plants, triggering morphological and physiological changes. The aim of this work was evaluate the ecophysiological development of moringa seedlings under controlled water restriction. The experimental design was completely randomized at 40, 60, 80, and 100% of field capacity and six replicates.

8. Reproductive phenology differs between evergreen and deciduous species in a Northeast Brazilian savanna
ABSTRACT Evergreen (EG) and deciduous (DEC) species exhibit distinct strategies to overcome dry periods and achieve adequate water status for reproduction and growth. Such particularities may result in distinct reproductive strategies between these groups. Thus, we evaluated the phenology of EG and DEC groups, comparing and differentiating their reproductive

9. Seasonal variation in gas exchange by plants of Erythroxylum simonis Plowman
ABSTRACT Erythroxylum simonisis an understory species found in Northeast Brazil. Due to its shaded habitat,E. simonisis subjected to seasonal oscillations of the environment, to which it must respond ecophysiologically. The objective of this study was to evaluate the effects of seasonality on the ecophysiology ofE. simonis in a fragment of Seasonal Semidecid

10. Ecophysiological and biochemical variation of the surf zone diatom asterionellopsis glacialis sensu lato from Santa Catarina, Southern Brazil
Resumo Manchas formadas por densas acumulações de diatomáceas na zona de arrebentação ("diatomáceas de surf") são comuns em praias arenosas com estados morfodinâmicos dissipativos ou intermediários. Seu aparecimento está correlacionado com fatores ambientais, como a passagem de frentes frias, quando ventos em direção a praia promovem maior hidrod

11. Effects of sex and altitude on nutrient, and carbon and nitrogen stable isotope composition of the endangered shrub Baccharis concinna G.M. Barroso (Asteraceae)
ABSTRACT Previous ecological studies of dioecious plant species have found that female plants preferentially occur at lower altitudes where there are typically better nutritional conditions, while male plants often occur in less favorable sites. We compared the ecophysiological performance of male and female plants in three populations of the dioecious Bacch

12. Distribution of the members of the Pipiens Assemblage in the sympatric area from Argentina: which is where and when?
Given their medical and veterinary relevance, the members of the Pipiens Assemblage are a worldwide target of ecological research. The distribution of Culex pipiens s.s. and Cx. quinquefasciatus converge in Buenos Aires, Argentina, where hybrids have been detected. Each member of the assemblage exhibits a distinct eco-physiological behaviour that can affect
