Local competition and metapopulation processes drive long-term seagrass-epiphyte population dynamics [PDF]

open access: yes, 2013
It is well known that ecological processes such as population regulation and natural enemy interactions potentially occur over a range of spatial scales, and there is a substantial body of literature developing theoretical understanding of the interplay ...

Biomass-density data analysis: a comment on Cabaco et al. (2013) [PDF]

open access: yes, 2015
Appropriate use of mathematics and statistics is fundamental for sound interpretations of ecological results and to prevent inaccurate conclusions. Throughout the article by Cabaco etal.

Effects of nutrient enrichment on seagrass population dynamics: evidence and synthesis from the biomass-density relationships [PDF]

open access: yes, 2013
The available data from experimental and descriptive studies on seagrass biomass and density responses to nutrient enrichment were analysed to assess the intraspecific mechanisms operating within seagrass populations and whether biomass-density ...

Population dynamics of Müllerian mimicry under interspecific competition

open access: yesEcological 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 ...

Dynamic analysis of competition and complementarity for light and N use to understand the yield and the protein content of a durum wheat-winter pea intercrop [PDF]

open access: yes, 2010
In a previous paper (Bedoussac and Justes 2009, Plant and Soil DOI: 10.1007/s11104-009-0082-2), we showed that intercropping of durum wheat and winter pea increased the yield and protein concentration of durum wheat when early N availability was less ...

Susceptibility and resistance of minnows, Phoxinus phoxinus (L.) to Gyrodactylus salaris Malmberg, 1957 (Monogenea) under laboratory conditions

open access: yesFauna Norvegica, 1990
The host susceptibility and resistance of minnows, Phoxinus phoxinus, to Gyrodactylus salaris was examined under laboratory conditions. The following experiments were carried out: transmission rate was examined by exposure of uninfected minnows to ...

Notes on Norwegian marine Amphipoda. 10. Scavengers and fish associates

open access: yesFauna 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

Species assembly in model ecosystems, II: Results of the assembly process [PDF]

open access: yes, 2010
In the companion paper of this set (Capitan and Cuesta, 2010) we have developed a full analytical treatment of the model of species assembly introduced in Capitan et al. (2009).

First record of gooseneck barnacles Conchoderma auritum on a minke whale Balaenoptera acutorostrata

open access: yesFauna Norvegica, 1986
Clusters of a stalked barnacle, identified as Conchoderma auritum were found attached to both damaged and complete baleen plates of a male minke whale caught off the coast of East Greenland on 16 July 1984.

A game-theoretic model of interspecific brood parasitism with sequential decisions [PDF]

open access: yes, 2008
The interaction between hosts and parasites in bird populations has been studied extensively. This paper uses game-theoretic methods to model this interaction.
