Intraspecific home range scaling: a case study from the owl limpet (Lottia gigantea)

Creator:: Fenberg, Phillip B.
Abstract:: Background: The owl limpet (Lottia gigantea) is an ectothermic invertebrate that inhabits the rocky intertidal zone where it territorially defends home ranges and grazes algae growing on the rocks. Among endothermic species, home range scales isometrically with body mass. Hypothesis: Home range area scales isometrically (scaling exponent ∼1.0) across individuals...

Shrimp adjust their sex ratio to fluctuating age distributions

Creator:: Charnov, Eric L. and Hannah, Robert W.
Abstract:: Long-term data sets that quantitatively confirm basic ecological theory are rare for field populations. Highly variable recruitment often causes wide temporal variation in population age distribution and basic theory for adaptive sex ratio often predicts ‘sex ratio tracking’ to match the fluctuating age distribution. Using sex-changing shrimp as a model...

Human hunting mortality threshold rules for extinction in mammals (and fish)

Creator:: Charnov, Eric L. and Zuo, Wenyun
Abstract:: Question: Are there general life-history rules for exploitation-caused extinction of mammal populations? Mathematical methods: A population of size N faced with the added mortality of human exploitation will deterministically go extinct if its per-capita birth rate can no longer match its per-capita mortality rate as N approaches zero. We develop...

Using evolutionary economics to explain predator-prey anomalies in the fisheries or explaining micky mouse's ears

Creator:: Wilson, James R.
Abstract:: The development of several sub-fields of general economics, including those of bounded rationality, institutional economics and the evolutionary economics, has expanded the scope and intensity of the dialogue both within economics, as well as between economists and other scientists. One of the more important preoccupations of early evolutionary economics was...

Evolutionary and ecological interactions affecting seaweeds

Creator:: Olson, Annette M.
Abstract:: The term "interaction" in evolutionary biology and ecology describes the relationships among variables in two classes of causal models. In the first, "interaction" refers to the influence of a single putatively causal variable on a variable of interest. In the second class of models, the term applies when a third...

A model of trophic evolutionary pathways

Creator:: Morris, A. Kimo
Abstract:: Calow (1983) realized that differences between parasites and their free-living relatives can be explained by the differences in nutrient richness. I propose a model that is based on Calow's idea which identifies the relative position of different trophic strategies (e.g. predation, grazing, parasitism and others) based on (1) the differences...

The genus Caenorhabditis : a system for testing evolutionary questions

Creator:: Raboin, Michael J.
Abstract:: Caenorhabditis elegans is arguably the best understood animal on the planet. Used for over 50 years to study development, we have a vast amount of knowledge of the inner workings of this worm. Our knowledge is incomplete, however, without placing this organism in its evolutionary and ecological context. In this...

Abstract:: We live in an exciting time for biology. Technological advances have made data collection easier and cheaper than we could ever have imagined just 10 years ago. We can now synthesize and analyze large data sets containing genomes, transcriptomes, proteomes, and multivariate phenotypes. At the same time, society's need for...

The Influence of fire on the Radiocarbon Signature and Character of Soil Organic Matter in the Siskiyou National Forest, Oregon, USA

Creator:: Heckman, Katherine, Campbell, John, Powers, Heath, Law, Beverly, and Swanston, Chris
Abstract:: Forest fires contribute a significant amount of CO₂ to the atmosphere each year, and CO₂ emissions from fires are likely to increase under projected conditions of global climate change. In addition to volatilizing aboveground biomass and litter layers, forest fires have a profound effect on belowground carbon (C) pools and...

The evolutionary stability of partial migration

Creator:: Ohms, Haley A.
Abstract:: Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...
