Reproductive interference between Nehalennia damselfly species
Ecoscience, 2007ABSTRACT We tested the hypotheses that reproductive interference between 2 congeneric damselfly species influences their local population densities and the female morph ratios in one of the species. Nehalennia irene has 2 female types (andromorph and gynomorph), whereas N. gracilis exhibits only one female type. Andromorphic N.

Ecological character displacement caused by reproductive interference
Journal of Theoretical Biology, 2007We carried out a theoretical investigation of whether ecological character displacement can be caused by reproductive interference. Our model assumes that a quantitative character is associated with both resource use and species recognition, and that heterospecific mating incurs costs. The model shows that ecological character displacement can occur as

Reproductive interference can promote recurrent speciation
Population Ecology, 2015Abstract Many consequences of reproductive interference have important implications in biodiversity conservation policy. After briefly summarizing our comments on the articles in this special feature, we focus on the role of reproductive interference in speciation due to geographic isolation with only infrequent migration between ...

Competitive exclusion through reproductive interference
Population Ecology, 1992Summary A simple differential equation model was developed to describe the competitive interaction that may occur between species through reproductive interference. The model has the form comparable to Volterra's competition equations, and the graphical analysis of the outcome of the two‐species interaction based ...

The effects of secondary task interference on shape reproduction
Experimental Brain Research, 2009The influence of a secondary task on speeded responses, and its effect on the outcome of more complex tasks has been studied in detail. However, the consequence of task interference on specific movement parameters other than speed and accuracy has been largely ignored. The current study examines how performing a secondary task impacts the drawing of an

Reproductive interference between three parapatric species of reptile tick
Oecologia, 1982Reproductive interference between three species of reptile tick, Aponomma hydrosauri, Amblyomma albolimbatum and Amb. limbatum was investigated. Adults of two species attach together on the same lizard hosts in narrow overlap zones at parapatric boundaries between species, providing opportunities for interference.

Interference among cotton neighbours after differential reproductive damage
Oecologia, 1997In indeterminate plant species, the rate of vegetative growth usually declines during the stage of active reproductive growth. Fruit shedding, as induced by insect herbivores, could counteract this decline. Due to the relative increase in vegetative growth, plants that have suffered reproductive damage could be better able to intercept light and ...

Experimental evidence suggests that reproductive interference between heterospecifics can seriously affect individual fitness; support from field studies for such an effect has, however, remained scarce. We studied reproductive interference in 25 natural breeding ponds in an area where two ranid frogs, Rana dalmatina and Rana temporaria, co-occur.

Interference with Reproductive Choice
1989This position paper begins with an analysis of all types of reproductive choice, and of the circumstances under which those choices are maximized or undermined. Although we have spoken of reproductive choice most often in terms of the right to choose abortion, in fact, the concept is far broader.

Island biogeography as a test of reproductive interference
Population Ecology, 2015Abstract Theoretical studies have predicted that reproductive interference must exclude either of the interacting species, but no testing of this prediction has ever been reported for natural populations.
