Increased Floral Rewards due to Local Adaptation Drives Plant Ecological Speciation via Learned Preferences of Pollinators

期刊: AMERICAN NATURALIST, 2022; 200 (6)

In animal-pollinated plants, the growth environment and pollination environment are two important agents of natural selection. However, their simultan......

Hazardous Loss of Genetic Diversity through Selective Sweeps in Asexual Populations

期刊: AMERICAN NATURALIST, 2022; 199 (3)

With the twofold cost of sex, derived asexual organisms have an immediate reproductive advantage over their sexual sisters. Yet the twiggy phylogeneti......

Quantitative Prediction of Interactions in Bipartite Networks Based on Traits, Abundances, and Phylogeny*

期刊: AMERICAN NATURALIST, 2022; 199 (6)

Ecological interactions link species in networks. Loss of species from or introduction of new species into an existing network may have substantial ef......

Kangaroo Fathers Modulate Maternal Control of Offspring Sex but Not Postpartum Maternal Expenditure

期刊: AMERICAN NATURALIST, 2022; 200 (6)

When sons and daughters have different fitness costs and benefits, selection may favor deviations from an even offspring sex ratio. Most theories on s......

Maternal and Paternal Age Effects on Male Antler Flies: A Field Experiment

期刊: AMERICAN NATURALIST, 2022; 199 (3)

In many species, parental age at reproduction can influence offspring performance and life span, but the direction of these effects and the traits aff......

The Origin of Asexual Brine Shrimps

期刊: AMERICAN NATURALIST, 2022; 200 (2)

Determining how and how often asexual lineages emerge within sexual species is central to our understanding of sex-asex transitions and the long-term ......

Evolution of Social Organization: Phylogenetic Analyses of Ecology and Sexual Selection in Weavers

期刊: AMERICAN NATURALIST, 2022; 200 (2)

Crook published a landmark study on the social organization of weavers (or weaverbirds, family Ploceidae) that contributed to the emergence of sociobi......

Adaptive Maternal Effects Shape Offspring Phenotype and Survival in Natal Environments

期刊: AMERICAN NATURALIST, 2022; 200 (6)

Maternal effects can give newborns a head start in life by adjusting natal phenotypes to natal environments, yet their strength and adaptiveness are o......

Game Theory in Biology: Moving beyond Functional Accounts

期刊: AMERICAN NATURALIST, 2022; 199 (2)

The idea of applying game theory to problems in biology was given a formal basis nearly 50 years ago. Since then, the theory has advanced, and there h......

Reproductive Character Displacement in Genital Morphology in Ohomopterus Ground Beetles

期刊: AMERICAN NATURALIST, 2022; 199 (3)

Genital morphology reveals rapid diversification among species, and species-specific divergence in genital morphology may result in reproductive isola......

Coexistence under Hierarchical Resource Exploitation: The Role of the R*-Preemption Trade-Off

期刊: AMERICAN NATURALIST, 2022; 200 (2)

Resource competition theory predicts coexistence and exclusion patterns based on species' R*s, the minimum resource values required for a species to p......

The Adaptive Potential of Nonheritable Somatic Mutations

期刊: AMERICAN NATURALIST, 2022; 200 (6)

The adaptive potential of nonheritable somatic mutations has received limited attention in traditional evolutionary theory because heritability is a f......
