Geographic variation in calcium and clutch size
For over a half century numerous hypotheses have surfaced aimed at explaining a key life history trait, the evolution of clutch size in birds. A principal goal has been to explain why clutch size generally increases with latitude both within species and among closely related species. Most hypotheses have stressed food limitation, predation, or seasonality. I present a novel hypothesis to explai...
متن کاملContributions of Proximate Determinants to Fertility Transition in Bangladesh: An Analysis of Bongaarts’ Fertility Model
Introduction: Fertility transition is outright by prime four proximate determinants (marriage, contraception, postpartum infecundability, and abortion). The present study examines the contributions of proximate determinants on fertility decline and quantifies inhibiting the effect of major proximate determinants according to the socioeconomic characteristics in Bangladesh.<br /...
متن کاملReal World Modeling and Nonlinear Control of an Electrohydraulic Driven Clutch
In this paper, a complete model of an electro hydraulic driven dry clutch along with its performance evaluation has elucidated. Through precision modeling, a complete nonlinear physical and full order sketch of clutch has drawn. Ultimate nonlinearities existent in the system prohibits it from being controlled by conventional linear control algorithms and to compensate the behavior of the sy...

متن کاملAvian egg size: variation within species and inflexibility within individuals.
Egg size is a widely-studied trait and yet the causes and consequences of variation in this trait remain poorly understood. Egg size varies greatly within many avian species, with the largest egg in a population generally being at least 50% bigger, and sometimes twice as large, as the smallest. Generally, approximately 70% of the variation in egg mass is due to variation between rather than wit...
