Pelagic zooplankton samples from Lake Biwa, Japan, collected monthly since 1971, were
analyzed for biomass and body size structure. Our aim was to clarify the relative effects of …

The appearance of invasive species threatens the integrity of aquatic ecosystems. Much is
known about dispersal and introduction mechanisms while little is known on the biological …

Exponential increase in respiration rate with increasing temperature in poikilotherms is well
documented, however, the rate of change varies greatly across copepod taxa. Studies often …

Acute acidic stress from sources such as acid rain might impact lake ecosystems in many
aspects. Because zooplankton are sensitive to environmental change, they could be a good …

The understanding of the biological responses of copepods under crowding conditions
contributes to establish their stable cultures at high densities for aquaculture industry, which …

The seasonal cycle is an important feature of life, leading to the succession of different
species and allowing them to share a common environment. Disruption in the seasonal …

Zooplankton change metabolic function as a physiological response to crowding. Unclear is
whether zooplankton physiological responses also change according to species and …

The seasonal fluctuations of the copepod Eodiaptomus japonicus, which dominates the
zooplankton community of Lake Biwa, have been disrupted several times over the past 45 …

We present here the first report of the mate-seeking behaviors of the calanoid copepod
Eodiaptomus japonicus. Analyses of three-dimensional (3D) recordings revealed that males …

The calanoid copepod Eodiaptomus japonicus is a key species in the zooplankton
community and plays a vital role in the food chain of the Lake Biwa ecosystem. We …
