Journal ArticleDOI
The evolution of body size: what keeps organisms small?
TL;DR: A review of the literature indicates a substantial lack of empirical evidence for these various mechanisms and highlights the need for experimental studies that specifically address the fitness costs of being large at the ecological, physiological, and genetic levels.
Journal ArticleDOI
The importance of being large: the relationship between size and fitness in females of the parasitoid Aphaereta minuta (Hymenoptera: Braconidae)
TL;DR: The relationship between a number of constraints and female size was studied in the parasitoid Aphaereta minuta, and larger females were found to have more eggs available, have larger eggs, live longer and have a higher searching efficiency within patches than small females, but searching efficiency for patches and travel speed were finding to be independent of size.
Journal ArticleDOI
Information gathering and decision making about resource value in animal contests
Gareth Arnott,Robert W. Elwood +1 more
TL;DR: In this paper, the authors provide a categorical framework in which the degree of resource assessment may be evaluated and also note limitations of various approaches and place studies in six categories: no assessment, internal state such as hunger influencing apparent value, cases of the contestants differing in assessment ability, mutual and equal assessment of value, (5) cases where opponents differ in resource value and (6) particularly complex assessment abilities that involve a comparison of the value of two resources.
Journal ArticleDOI
A field study of size–fitness relationships in the parasitoid Asobara tabida
TL;DR: The majority of females appeared to be time-limited, and the increase in fitness with size is predominantly due to a larger dispersal ability and not to a higher egg load.

Does floral nectar improve biological control by parasitoids
George E. Heimpel,Mark A. Jervis +1 more
TL;DR: The hypothesis that plant diversification can decrease pest pressure by providing sugar to parasitoids that would otherwise be sugar-limited has its origins in anecdotal or semi-quantitative observations of increased parasitism rates and biological control in the vicinity of flowering plants.

Generalized Linear Models
Peter McCullagh,John A. Nelder +1 more
TL;DR: In this paper, a generalization of the analysis of variance is given for these models using log- likelihoods, illustrated by examples relating to four distributions; the Normal, Binomial (probit analysis, etc.), Poisson (contingency tables), and gamma (variance components).
Journal ArticleDOI
An Analysis of Transformations
George E. P. Box,David Cox +1 more
TL;DR: In this article, Lindley et al. make the less restrictive assumption that such a normal, homoscedastic, linear model is appropriate after some suitable transformation has been applied to the y's.
Journal ArticleDOI
The evolution of life histories
TL;DR: In this article, age and size at maturity at maturity number and size of offspring Reproductive lifespan and ageing are discussed. But the authors focus on the effects of age and stage structure on fertility.
Journal ArticleDOI
Generalized Linear Models
TL;DR: In this paper, the authors used iterative weighted linear regression to obtain maximum likelihood estimates of the parameters with observations distributed according to some exponential family and systematic effects that can be made linear by a suitable transformation.

Analysis of Survival Data
David Cox,D. Oakes +1 more
TL;DR: In this article, the authors give a concise account of the analysis of survival data, focusing on new theory on the relationship between survival factors and identified explanatory variables and conclude with bibliographic notes and further results that can be used for student exercises.
