Population dynamics of Müllerian mimicry under interspecific competition
Ecological Modelling, 2009 Abstract We ask what the effects of mutualism on population dynamics of two competitive species are. We model the population dynamics of mutualistic interactions with positive density- and frequency-dependences. We specifically assume the dynamics of Mullerian mimicry in butterflies, where the mortality of both species is reduced depending on the ...

Notes on Norwegian marine Amphipoda. 10. Scavengers and fish associates
Fauna Norvegica, 1985 The dominant group of carrion-eating amphipods in Norway are the Lysianassoidea; they play an important role as scavengers in Norwegian and arctic waters. A number of genera damage fish caught in nets and on long-lines; in Norway the most serious damage

Interspecific competition slows range expansion and shapes range boundaries
, 2020 Species expanding into new habitats as a result of climate change or human introductions will frequently encounter resident competitors. Theoretical models suggest that such interspecific competition can alter the speed of expansion and the shape of ...
