Wheat (Triticum aestivum L.)/faba bean (Vicia faba L.) intercropping shows significant overyielding and high nitrogen (N)-use efficiency, but the dynamics of plant interactions have rarely been estimated.

Interspecific behavioural interference and range dynamics: current insights and future directions
ABSTRACTNovel biotic interactions in shifting communities play a key role in determining the ability of species' ranges to track suitable habitat. To date, the impact of biotic interactions on range dynamics have predominantly been studied in the context of interactions between different trophic levels or, to a lesser extent, exploitative competition ...

Interacting phenotypes and the coevolutionary process: Interspecific indirect genetic effects alter coevolutionary dynamics [PDF]
AbstractCoevolution occurs when species interact to influence one another’s fitness, resulting in reciprocal evolutionary change. In many coevolving lineages, trait expression in one species is modified by the genotypes and phenotypes of the other, forming feedback loops reminiscent of models of intraspecific social evolution. Here, we adapt the theory

Background Interspecific hybridization plays vital roles in enriching animal diversity, while male hybrid sterility (MHS) of the offspring commonly suffered from spermatogenic arrest constitutes the postzygotic reproductive isolation.

Distribution of the field mice Apodemus flavicollis and A. sylvaticus in Norway
Examination of specimens of yellow-necked and wood mice in Norwegian museum collections showed that yellow-necked mice are confined to areas with a continental climate, east and northwest of the South Norwegian watershed.

Hemioniscus balani Buchholz in northern Norway (Isopoda, Cryptoniscina)
The parasitic isopod Hemioniscus balani Buchholz is widespread and common on the outer coasts of northern Norway. Infection percentages show a clear vertical gradient, from 0 % in the high intertidal Balanus balanoides belt to a maximum (up to 70-80 ...

The stomach contents of 0 to 3 year old salmon were investigated throughout a single 20 hour period in each of July, August and September 1981. There was no marked diurnal variation in stomach content of fry, while that of parr indicated nocturnal ...

Infections by Gyrodactylus salaris of Atlantic salmon in the river Vikja were discovered in 1981. To prevent further spreading of the parasite to neighbouring rivers in the Sognefiord area, the river was treated with rotenone in November 1981 and in May
