Growth strategies and optimal body size in temperate pararginii butterflies.
In temperate insects the evolution of growth strategies and the optimal age and size at maturity will depend strongly on seasonal variation in temperature and other resources. However, compared to photoperiod, temperature itself is a relatively poor predictor of seasonal change and timing decisions in insects are often most strongly influenced by the photoperiod. Here I review the evolution of ...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Fitness and Optimal Body Size in Zooplankton Population
A measure of fitness which is an explicit function of feeding efficiency and vulnerability to predation is introduced. Feeding efficiency is a function of feeding and respiration rates and the nature of the food supply. Defining fitness as a function of body size reveals several potential explanations for the evolution of life-histories and for mechanisms of competition in zooplankton populatio...
متن کاملTrophic strategies , animal diversity and body size Kevin
Although reproduction is the overriding theme of the drama of life, feeding and being fed on, are the key subplots. For this reason, ecologists and evolutionary biologists are well aware of the importance of predation and are increasingly considering the role of parasitism in the control of populations and the structure of communities. A barrier to fully incorporating concepts about parasitism ...
متن کاملInsular carnivore biogeography: island area and mammalian optimal body size.
Patterns of size variation in insular mammals have been used to support the claim that mammals have a single optimal body size. This hypothesis enjoys wide support, despite having been questioned on both theoretical and empirical grounds. It is claimed that species of optimal size maintain the highest population densities. Therefore these species are thought to inhabit the smallest islands, whe...
