Explanations for the coexistence of many closely related species in inland waters continue
to be generated more than 50 years after Hutchinson's question: why are there so many …

Coastal zones are productive areas that serve as nursery grounds for a large number of
marine species. However, the processes involved in survival success during the juvenile …

The concept of native range in invasion biology is difficult to define since, in many cases, this
type of range is unknown and cannot be determined. We investigate the uncertainties …

This chapter is an introduction to the Phylum Mollusca and a review of freshwater gastropod
systematics, evolution, regional distribution and diversity, reproduction and life history …

Controlling invasive species can restore ecosystems while also quantifying species
interaction strengths. We experimentally removed invasive rusty crayfish (Orconectes …

Body size is associated with fundamental biological processes such as metabolism,
movement, and the rate of reproduction and evolution. Although allometric principles should …

Thermal constraints on the time available for activity have been proposed as a proximate
mechanism to explain variation in suites of life history traits. The longer that an ectotherm …

Hydrophilic, or water-loving, macrophytes characterize wetland ecosystems, indicating
prerequisite conditions of hydric soils and sufficient hydrology. The presence of such …

Field and laboratory experiments were conducted to investigate the excretion stoichiometry
of nitrogen (N) and phosphorus (P) of two benthic macroinvertebrate grazers, the crayfish …

We examined the response to chemical cues from fish and crayfish, two predators with
contrasting feeding modes, and their single and combined effect on shell morphology in the …
