Warming advances virus population dynamics in a temperate freshwater plankton community

Disrupted seasonal clockwork in the population dynamics of a freshwater copepod by climate warming

Life history responses are expected to accompany climate warming, yet little is known how long-term effects of climate and environmental change affect the seasonal dynamics of planktonic organisms. We used an historical data set from Lake Washington (U.S.A.) to quantify population responses of a calanoid copepod (Leptodiaptomus ashlandi) to long-term changes in temperature and resource availabi...

Models for adaptive feeding and population dynamics in plankton

Traditionally, differential-equation models for population dynamics have considered organisms as “fixed” entities in terms of their behaviour and characteristics. However, there have been many observations of adaptivity in organisms, both at the level of behaviour and as an evolutionary change of traits, in response to the environmental conditions. Taking such adaptiveness into account alters t...

Archaeal and bacterial community composition of sediment and plankton from a suboxic freshwater pond.

We studied the composition of archaeal and bacterial communities present in the sediment and plankton of a shallow suboxic-to-anoxic freshwater pond with high organic matter input, as an example of a kind of inland freshwater system widely distributed in forests of temperate regions. Molecular surveys based on small subunit rRNA genes showed a remarkably high diversity of lineages within the Ba...

Climate change and community disassembly: impacts of warming on tropical and temperate montane community structure.

Both tropical and temperate species are responding to global warming through range shifts, but our understanding of the consequences of these shifts for whole communities is limited. Here, we use current elevational range data for six taxonomic groups spanning 90° in latitude to examine the potential impacts of climate-driven range shifts on community change, or 'disassembly', across latitude. ...
