While juvenile white sharks (JWS) can display regional endothermy, the need to maintain internal temperatures within an energetically favorable range likely drives thermoregulatory movements to maximize growth and foraging efficiency. Many JWS from the northeastern Pacific population aggregate seasonally in nearshore nursery habitats throughout the Southern California Bight and historic data show that inter-seasonal movement p...

We studied short‐term herbivory and recovery of microalgal communities grazed by snails ( Potamopyrgus antipodarum ) , mayflies ( Deleatidium spp.), and caddisflies ( Pycnocentrodes aeris ) in microcosms containing low algal food supplies characteristic of grazer‐controlled streams. Herbivore biomass was standardised across single‐species treatments to assess grazing effects owing to taxon‐specific differences in feeding modal...

A new diatom, Frankophila biggsii, is described from freshwater subaerial wet limestone/ dolomite wall habitats on the South Island of New Zealand. Although the appearance of Frankophila in the light microscope would lead one to assume that this diatom belonged to the genus Staurosira, Staurosirella, or perhaps Pseudostaurosira, the presence of a reduced raphe at the valve apices places it in the genus Frankophila. The morphol...
