Paszkowski, C. A., Tonn, W. M., Holopainen, I. J.
Detecting mechanisms that structure ecological communities often requires investigations at appropriate spatial and temporal scales. A 15-mo, whole-lake experiment revealed direct and indirect mechanisms by which a fish predator structured its prey population, primarily by affecting recruitment...

Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, Canada
Download2005
McMaster, N. L., Schindler, D. W.
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...

Cahill, J. F., Mitchell, M. G. E., Hik, D. S.
We investigated whether plant interaction intensity in a subarctic-alpine meadow is important for determining community structure and species abundance. Using two common species as phytometers, we measured interaction intensity using a neighbor removal approach. Eight biotic and abiotic variables...

Plant phenotypic plasticity belowground: a phylogenetic perspective on root foraging trade-offs
Download2005-01-01
Many plants proliferate roots in nutrient patches, presumably increasing nutrient uptake and plant fitness. Nutrient heterogeneity has been hypothesized to maintain community diversity because of a trade-off between the spatial extent over which plants forage (foraging scale) and their ability to...

Wishart, D.S., Stothard, P., Dong, X., Forsythe, I.
PlasMapper is a comprehensive web server that automatically generates and annotates high-quality circular plasmid maps. Taking only the plasmid/vector DNA sequence as input, PlasMapper uses sequence pattern matching and BLAST alignment to automatically identify and label common promoters,...

Reha-Krantz, L., Jack, W. E., Langhorst, B. S., Nichols, N.
ABSTRACT Polbase (http://polbase.neb.com) is a freely accessible database of DNA polymerases and related references. It has been developed in a collaborative model with experts whose contributions reflect their varied backgrounds in genetics, structural biology and biochemistry. Polbase is...
