Notes on Norwegian marine Amphipoda. 8. Amphipods found in association with sponges and tunicates
Nineteen amphipod species in seven different families have been recorded living on or in Porifera and/or Tunicata in Norwegian waters. Of these Laothoes meinerti, Cheirimedon latimanus and two species of Paramphithoidae are confined to sponges, while ...

Interspecific morphological variation in Juglandoideae resting bud organisation-a winter's tale?
BACKGROUND AND AIMS Dormant resting buds are frequently regarded as static units, with protective cataphylls on the outside and embryonic foliage leaves on the inside.

Deciphering how climatic variability modulates the interspecific interactions in natural systems is one of the most interesting and least studied ecological processes. Rodent outbreaks or irruptions in semiarid Chile are associated with rainfall pulses driven by the El Niño Southern Oscillation (ENSO). During the last decade, north‐

EFFECTS OF REFUGES AND DENSITY DEPENDENT DISPERSAL ON INTERSPECIFIC COMPETITION DYNAMICS
We present a classical interspecific competition model. Individuals compete for a resource on a common patch and can go to a refuge. It is assumed that if species would remain on the competition patch, species 1 survives and species 2 would go extinct. Therefore, species 1 is Locally Superior Competitor (LSC) and species 2 Locally Inferior Competitor (

During the years 1980 - 1986, an intensive whitefish, Coregonus lavaretus, exploitation programme was carried out in the mountain reservoir Goppollen, SE Norway, in an attempt to improve whitefish quality and to reduce interspecific competition between ...

Weeds are a permanent constraint on crop productivity in agriculture. Due to the importance of the effect of weeds on the crop, there has been great interest in establishing the competitive ability of each species to optimize its control.

Carlin-tagged Atlantic salmon smolts have been released in the River Eira in western Norway during the period 1961 - 1980. Just after release birds were observed as smolt predators.

Conventional niche overlap measurements are not effective for assessing interspecific competition
Interspecific competition is notoriously difficult to detect and quantify, especially in species that are wide-ranging or otherwise difficult to track in the wild.
