Summer changes in the vertical distribution of chlorophyll-a in Boeckella Lake (Hope Bay, Antarctic Peninsula)

Antarctic Record, 1996
Vertical distribution of phytoplanktonic chlorophyll-α in Boeckella Lake was studied during summer periods in 1992 and 1993. Two opposite sites subjected to different organic matter inputs from the adjacent penguin rookeries were periodically sampled at ...

DISTRIBUTIONAL PATTERNS OF THE SOUTH AMERICAN SPECIES OF BOECKELLA (COPEPODA: CENTROPAGIDAE): A TRACK ANALYSIS [PDF]

Journal of Crustacean Biology, 2000
Abstract South American species of the freshwater copepod genus Boeckella are distributed in the Andean region, which corresponds to southwestern South America below 30° south latitude, also extending along the Andean highlands north of this latitude, and comprises the Subantarctic, Central Chilean, Patagonian, and Paramo-Puna subregions.

Experimental hybridization of alpine and lowland forms of Boeckella dilatata, a calanoid copepod [PDF]

Heredity, 1993
The freshwater calanoid copepod Boeckella dilatata Sars inhabits lakes and ponds of glacial origin in central and southern South Island, New Zealand. In lowland lakes and ponds, this copepod is small and transparent while in alpine bodies of water, it is larger and bright red.

Contrasting patterns of MAAs accumulation in two populations of the copepod Boeckella gracilipes

Photochemical & Photobiological Sciences, 2014
The bio-accumulation of mycosporine-like amino acids (MAAs) is common in planktonic copepods that inhabit environments exposed to high levels of solar radiation. MAAs accumulation in copepods can be affected both by extrinsic (environmental) and intrinsic factors (local adaptation, genotype, etc.). Laboratory experiments were performed to study the bio-
