Female body size, fecundity parameters and foundation of new colonies in Anelosimus jabaquara (Araneae, Theridiidae)
(Birkhauser Verlag AgBaselSuíça, 2001)
Sexual development, size at maturity, size at maternity and fecundity of the blue shark Prionace glauca (Linnaeus, 1758) in the Southwest Atlantic
(Elsevier B.V., 2014-12-01)
Size at maternity and size at maturity of the blue shark Prionace glauca were studied from samples collected during ten commercial longline fishing cruises off southern Brazil and in adjacent international waters. The sharp ...
Honey Ants (Genus Myrmecocystus) Macroecology: Effect of Spatial Patterns on the Relationship between Worker Body Size and Geographic Range Size
(1998-10-01)
Macroecology evaluates the partitioning of physical space and resources among organisms through correlation among ecological variables, such as geographical range size and shape, body size, and population density, measured ...
Variation in body size and metamorphic traits of Iberian spadefoot toads over a short geographic distance
(Wiley Blackwell Publishing, Inc, 2008-06)
Determinants of geographic variation in body size are often poorly understood, especially in organisms with complex life cycles. We examined patterns of adult body size and metamorphic traits variation in Iberian spadefoot ...
Size-Dependent Selective Mechanisms on Males and Females and the Evolution of Sexual Size Dimorphism in Frogs
(Univ Chicago Press, 2014-12-01)
Sexual size dimorphism (SSD) varies in animals from male biased to female biased. The evolution of SSD is potentially influenced by a number of factors, such as territoriality, fecundity, and temporal breeding patterns ...
Age, body size and growth pattern of Argenteohyla siemersi pederseni (Anura: Hylidae) in northeastern Argentina
(Taylor & Francis, 2013-01)
In this study we analysed the body size, age structure, age at maturity, longevity and growth pattern of Argenteohyla siemersi pederseni in north-eastern Argentina using skeletochronological methods. Body size was sexually ...
Meal size effects on the postprandial metabolic response of Bothrops alternatus (Serpentes: Viperidae)
(2013-07-15)
We examined the effects of meal size on the postprandial metabolic response of the lancehead Bothrops alternatus (Duméril, Bibron & Duméril, 1894), fed mice equaling to 5, 10, 20, and 40% of the snake's body mass. The ...
Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(Elsevier B.V., 2017-05-01)
using environmentally relevant concentrations of arsenic and cobalt were conducted both in the presence and absence of aquatic humic substances (AHS) and the fractions of different molecular sizes in the range of (< 5, ...
Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(2017-05-01)
The release of contaminants in aquatic ecosystems can be influenced by humic acids. In this study, toxicity tests using environmentally relevant concentrations of arsenic and cobalt were conducted both in the presence and ...
Sexual dimorphism and gynoecium size variation in the andromonoecious shrub Caesalpinia gilliesii
(Wiley Blackwell Publishing, Inc, 2005-03)
The degree of sexual dimorphism in flowers and inflorescences can be evaluated early in flower development through the study of floral organ size co-variation. In the present work, the gynoecium-androecium size relationship ...
