Unit 17.2: Overview of Invertebrates

The fluid also cushions the internal organs. The pressure of the fluid within the cavity provides stiffness. It gives the body internal support ...

Diversity in the Brain Sizes of Newborn Mammals

Recombination and loss of complementation
... (Lewis, 1987). In fact, in species with isogamous gametes there is no such cost, and the argument therefore does not hold for the origin of sexual reproduction, when gametes were almost certainly isogamous. In species with anisogamous gametes, however, asexual reproduction (parthenogenesis) should r ...

Direct fitness or inclusive fitness: How shall we model kin selection?

If one type of development yielded higher returns in benthic juveniles per energy allocated to reproduction, t ...

To determine if survival varied among origin, transplant, or initial body condition, we used a generalized linear mixed effect model with a binomial error distribution; our model contained two random intercepts, transplant location and replicate nested within transplant location. Similarly, we used ...
