How the direct and indirect effects of species interactions cascade to affect community struc- ture, functioning, and stability is a fundamental question in ecology. In temperate …
Food webs are extraordinarily complex, containing myriad direct interactions and indirect effects. Determining how this network of interactions and effects influences a food web’s …
Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or …
A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are …
Diet variation among individuals within populations is widespread. Often diet dierences among individuals are attributable to obvious differences among individuals such as age, …
Parasites are increasingly recognized for their significant roles in shaping community structure and ecosystem dynamics. Due to their cryptic nature, however, they are often …
Understanding ecological interaction strengths is one of the main objectives of ecology. Recently, two methods for estimating interaction strengths of predator- prey interactions …
Current human – ocean relationships are dominated by unsustainable extraction of marine resources having both ecological and socio-economic consequences. Sustainable fishery …
There is increasing awareness that human activities are altering the ways that natural systems operate and that local shifts in species composition and abundance can lead to …
Invasive species are one of the greatest threats to biodiversity around the world. Although a seemingly harmless act, species introduction into a new ecosystem can have …
Kelp forests serve as an integral abode for aquatic species. Kelp forests are one of the most productive terrestrial systems, providing its denizens the conditions necessary for …
Two elements of food webs add significantly to their complexity: The presence of trophic omnivores and the nonlinear nature of predator-prey interactions. I introduce a new …
On the rocky shores of the Gulf of Maine, the American lobster, Homarus americanus, the Jonah crab, Cancer borealis, the Rock crab, Cancer irroratus, and the Green crab, Carcinus …
