Fish are an important component of many lakes, and a valuable resource in many countries,
yet knowledge of how fish populations have fluctuated in the past is very limited. One …

Cladocerans of the genus Daphnia are keystone pelagic filter feeders in many temperate
ponds and lakes. They have also become popular model organisms in various biological …

Calcium (Ca) concentrations are decreasing in softwater lakes across eastern North
America and western Europe. Using long-term contemporary and palaeo-environmental …

Little is known about native communities in naturally fishless lakes in eastern North America,
a region where fish stocking has led to a decline in these habitats. 2. Our study objectives …

Increases in dissolved organic matter and the consequent “browning” of some lakes in
recent decades are reducing water transparency to both ultraviolet and photosynthetically …

The genetic background of inducible morphological defences in Daphnia is still largely
unknown. Dissolved infochemicals from the aquatic larvae of the phantom midge Chaoborus …

Variations in climate, watershed characteristics and lake-internal processes often result in a
large variability of food-web complexity in lake ecosystems. Some of the largest ranges in …

Variation in the intensity of predation across the well‐known environmental gradient of
freshwater habitats from small, ephemeral ponds to large, permanent lakes is a key factor in …

Acidification has damaged biota in thousands of lakes and streams throughout eastern
North America. Fortunately, reduced emissions of sulphur dioxide and nitrogen oxides …

Chemical signals play an integral role in many predator–prey relationships but their
effectiveness can be altered by environmental conditions. Prey species can detect predator …
