1. 24. On Relative Growth in Asellus aquaticus

Author:
A. E. Needham
Source:
Proceedings of the Zoological Society of London 1937 v.A107 no.3 pp. 289-313
ISSN:

Subject:
Asellus aquaticus; abdomen; allometry; developmental stages; females; growth retardation; head; males; periodicity; population growth; vertebrates
Abstract:
... 1 In the relative growth of various width dimensions and total length in Asellus aquaticus the mean course of the later stages of growth shows simple allometry. 2 In detail, however, the growth‐curves show a regular rhythmicity which is essentially similar in all segments. It is suggested that the rhythmicity may be due to cyclic phenomena in absolute growth, the periodicity of the cycles in width ...

Abstract:
... : 1 The length of the hind limb of R. temporaria bears to the body length a linear relationship, which can be expressed by the equation y=ax+b. There is a change in the value of the constants a and b at a point which marks the onset of puberty in the female. 2 The weight of amphibians as deduced from mean group measurements of R. temporaria, T. cristatus, S. maculose, A. tigrinum, and R. esculenta ...

Abstract:
... Tropaeolum majus L., popularly known as nasturtium, is a species widely used in the form of infusions and salads. In the last years, the antihypertensive, diuretic, and calcium and potassium sparing activities of T. majus preparations were shown. Moreover, no preclinical 90-day oral toxicity studies were conducted. Thus, this study evaluated the toxicity of the hydroethanolic extract obtained from ...

Abstract:
... Bees and wasps could exhibit shape and size sexual dimorphism, and most of their morphological variation could depend on phenotypic responses due to environmental pressure during ontogenetic development. More complex measurement techniques related to size and shape rather than simply to mass and length should be required to analyze such a complex sexual dimorphism. In this study, differences relat ...

Abstract:
... Pomacea canaliculata , an invasive apple snail native to South America, is a serious pest of aquatic crops in several parts of the world. The origin of inter-population variation in shell shape is thought to be both genetic and environmental but the reaction norms to specific environmental factors are still poorly understood. Our aims were to analyze the existence of direct and indirect (allometri ...

Abstract:
... Static allometry of sexually selected traits has been the subject of intense research recently. However, some pitfalls for this kind of research are: (a) the functions of sexual traits are largely unknown; (b) more than one body size indicator must be measured; and, (c) allometry must be examined under different environmental circumstances to see whether allometric values change. Using Hetaerina a ...

Here we study sexual dimorphism in the static allometry of the legs of a large ground spider, Grammostola rosea (Walckenaer, 1837). We found that this species has a moderate sexual size dimorphism and males have longer legs relative to body size than females, simi ...
