Transgenic control of vectors: The effects of interspecific interactions [PDF]

, 2010
The control of insect vectors through conventional sterile insect or transgenic technologies (e.g., RIDL®) is an intense focus of research in the combat against vector-borne disease.

Intensive whitefish exploitation: effects on population structure of whitefish Coregonus lavaretus L. and brown trout Salmo trutta L. in a mountain reservoir

Fauna Norvegica, 1989
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 ...

Quantifying and Disentangling the Competition Effect of a Weed Community in a Long-Term Biennial Cereal-Legume Rotation

Agronomy, 2023
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.

Dynamics of sympatric vole populations: influence of interspecific competition

, 2007
We conducted removal experiments in open populations of Microtus ochrogaster and M. pennsylvanicus to test for potential interspecific competition between coexisting populations in bluegrass and tallgrass prairie in east-central IL, USA. Population densities of M. ochrogaster and M.

The dynamics of lncRNAs transcription in interspecific F1 allotriploid hybrids between Brassica species

Genomics, 2022
Interspecific hybridization is the intrinsic forces behind genome evolution. Long non-coding RNAs (lncRNAs) are important for plant biological processes regulation. However, it is unclear that these non-coding fractions are impacted by interspecific hybridization.

Bird predation on hatchery reared Atlantic salmon smolts, Salmo salar L., released in the River Eira, Norway

Fauna Norvegica, 1987
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.

Change in the degree of infestation of parasitic nematodes in Grey Seals Halichoerus grypus from Froan, Norway

Fauna Norvegica, 1988
Change in nematode infestation in stomachs of Grey Seals caught at the breeding ground at Froan on the coast of Sør-Trøndelag county, Norway, is recorded. The abundance of nematodes decreased from 1977/78 to 1982/84. In the first period more than 50% of

Identifying hybridizing taxa within the Daphnia longispina species complex: a comparison of genetic methods and phenotypic approaches

, 2010
Daphnia galeata Sars, D. longispina O. F. Muller and D. cucullata Sars (Crustacea: Cladocera) are closely related species which often produce interspecific hybrids in natural populations.

Seasonal variation of birds on a feeding site in a suburban area near Oslo, Norway

Fauna Norvegica
The birds visiting a feeding site near a villa in a suburban, residential area in Bærum municipality, west of Oslo, were monitored daily during 1997 - 99, and at irregular intervals during 1993 - 96. Sixteen species had a frequency of more than one week
