Data from: Ontogenetic and interspecific scaling of consumption in insects [PDF]
, 2015 The uptake of resources from the environment is a basic feature of all life. Consumption rate has been found to scale with body size with an exponent close to unity across diverse organisms.

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 ...

Data from: Ontogenetic and interspecific metabolic scaling in insects [PDF]
, 2014 Design constraints imposed by increasing size cause metabolic rate in animals to increase more slowly than mass. This ubiquitous biological phenomenon is referred to as metabolic scaling.

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

Notes on Norwegian marine Amphipoda. 8. Amphipods found in association with sponges and tunicates
Fauna Norvegica, 1984 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 ...
