The ultrastructure of the eyes of Paravortex karlingi (Plathelminthes, Rhabdocoela)
Both eyes of Paravortex karlingi belong to the rhabdomeric type. Each eye consists of a single pigment cup cell and three sensory cells. Modified...

Consumptive and non-consumptive effects of turbellarian (Mesostoma sp.) predation on anostracans
We assessed the predatory impact of Mesostoma sp. (Rhabditophora) on hatching and survival of Branchipodopsis wolfi (Anostraca) under laboratory...

Representation of aquatic invertebrate communities in subfossil death assemblages sampled along a salinity gradient of western Uganda crater lakes
We analysed subfossil death assemblages of aquatic invertebrate communities in a salinity series of 35 western Uganda maar-crater lakes to evaluate...

Spermatozoa and spermatogenesis in Genostoma kozloffi (Plathelminthes, Rhabdocoela)
Genostoma kozloffi Hyra, 1993, is a symbiotic plathelminth living beneath the carapace of Nebalia pugettensis (Clark, 1932) (Leptostraca Crustacea)....

Relationships among metazoan phyla as inferred from 18S rRNA sequence data: a methodological approach
The relationships among the phyla of Metazoa have been investigated by several authors. Different genes have been applied to this problem, but only...

Photoreceptors in species of the Macrostomida (Plathelminthes): ultrastructural findings and phylogenetic implications
The submicroscopic anatomy of intracerebral and pericerebral photoreceptors in six species of the Macrostomida is described. Cylindromacrostomum...

Status of the Nemertea as predators in marine ecosystems
The ecology of nemertean predators in marine ecosystems is reviewed. Nemerteans occur in most marine environments although usually in low abundances....

Predation rates of nemertean predators: the case of a rocky shore hoplonemertean feeding on amphipods
Estimates of the predation rates of benthic nemerteans are often based on observations of single individuals, and consequently they may not be...

A method for rapid abundance estimation of semiplanktonic meiofauna
Many meiofaunal copepods and plathelminths enter the tidal waters at night thus exhibiting a life-style intermediate between benthic and planktonic....

Dynamics of Daphnia hyalina × galeata in Castelo-do-Bode Reservoir: The effect of food availability and flatworm predation
Daphnia hyalina × galeata in Castelo-do-Bode Reservoir was regulated mainly by food availability during the summers of 1993 and 1994. Because of high...
