The influence of space in genetic-environmental relationships when environmental heterogeneity and seed dispersal occur at similar scale.
We tested the importance of microenvironmental topographic parameters as predictors of emmer wheat genetic variation using three classes of single-locus (or at most several-loci) genetic markers (allo…
-
When genes go to sleep: the population genetic consequences of seed dormancy and monocarpic perenniality.
In many annual plant populations, seeds may be dormant for several seasons before they germinate. Here, we investigate the consequences of both conditional (dispersed seeds cannot enter a dormant stag…
-
The evolutionary economics of immunity.
How much of its resources should an individual invest in a costly immune system? In this article, we apply an evolutionarily stable strategy analysis to an epidemic model to answer this question. On t…

Comparing alternative models to empirical data: cognitive models of western scrub-jay foraging behavior.
Animals often select one item from a set of candidates, as when choosing a foraging site or mate, and are expected to possess accurate and efficient rules for acquiring information and making decision…
-
Allee effects, immigration, and the evolution of species' niches.
Theoretical studies of adaptation to sink environments (with conditions outside the niche requirements of a species) have shown that immigration from source habitats can either facilitate or inhibit l…
-
Priority versus brute force: when should males begin guarding resources?
When should males begin guarding a resource when both resources and guarders vary in quality? This general problem applies, for example, to migrant birds occupying territories in the spring and to pre…

History and the species-area relationship in Lesser Antillean birds.
We examined the species-area relationship for three historically distinct subsets of Lesser Antillean birds identified by molecular phylogenetic analysis of island and continental populations. The gro…

The analysis of variation of mtDNA hypervariable region 1 suggests that Eastern and Western Pygmies diverged before the Bantu expansion.
The Eastern Pygmies from Zaire and Western Pygmies from Cameroon, Congo, and the Central African Republic represent the two principal groups of African Pygmies. In the "recent divergence" hypothesis i…

On the generality of the latitudinal diversity gradient.
The decline of biodiversity with latitude has received great attention, but both the concise pattern and the causes of the gradient are under strong debate. Most studies of the latitudinal gradient co…

Trade-offs during the development of primary and secondary sexual traits in a horned beetle.
Resource allocation trade-offs during development affect the final sizes of adult structures and have the potential to constrain the types and magnitude of evolutionary change that developmental proce…
