“…Its role is communication, whether defensive, attractive, or sexual (Herring, 1990a). This review examines the occurrence of bioluminescent sexual dimorphism in marine animals and the evidence for its role in sexual communication (Herring, 2000;Ruxton & Bailey, 2005).…”

This study evaluates the role of protozoa in larval fish feeding by describing protozoa in larval fish diets and testing the hypothesis that, in the Irish Sea, larval fish feed on protozoan prey at rates that potentially sustain their food requirements. Gut contents of 11 taxonomic groups of larval fish were examined, and protist prey occurred in the diet of all of them. Protozoan prey were identified, which provided an insight into their trophic role. Most of the protozoan prey were autotrophic or mixotrophic. In general, larval fish diets were constant over the spring/summer period, regardless of prey availability in the field and the composition of larval fish assemblage (taxonomy and size). A laboratory experiment on ingestion rates of flounder larvae as a function of ciliates concentration was conducted. Combined laboratory and field data showed that, in the Irish Sea, it is unlikely that ciliates are often the primary food source of flounder larvae, and, by implication, other larval fish as well. However, ciliates and other protozoa could be a substantial component of the larval fish diet, and they may potentially prevent food limitation.

“…Population densities in the ocean are generally low (Herring, 2000) and male competition is much less likely than female selection. A recent simulation (Ruxton & Bailey, 2005) suggests that it may take only a few hours for a male to arrive once a female has begun signalling.…”

“…We examine the impact of one little-studied mechanism of mate-finding, landmarking, on strong Allee thresholds. Gascoigne et al (2009) point out that there are two main categories of adaptations to mitigate mate-finding Allee effects: mechanisms that increase the efficiency of mate-finding at low density such as calls or chemical signalling (e.g., bioluminescent signalling of deep sea fishes: (Ruxton and Bailey 2005), and mechanisms that reduce the likelihood of low density such as mass spawning (e.g., spawning aggregations of cod: Skjraasen et al 2011). While mass aggregation may be disrupted at very low density (Reed and Dobson 1993;Rowe and Hutchings 2003), some mate-finding strategies such as pheromone signalling can be quite effective at small population size.…”

Landmarking and strong Allee thresholds

Mate-finding difficulties in small populations are often postulated to create strong demographic Allee effects that increase the probability of extinction of native species or, similarly, decrease the probability that nonnative species will successfully invade. Many species make use of a restricted number of mating locations, detectable from long-distance, that are not selected for habitat reasons (e.g., hilltopping in butterflies). This 'landmarking' strategy may specifically address the problem of overcoming matefinding difficulties. Using a variant of the birthday problem, we demonstrate that populations which locate a restricted number of mate-finding sites using landmark features may have high probability of successful mating even at very low population densities. Therefore, a strong Allee threshold, if it exists, may be very small, and non-native species that make use of this strategy may have a very good chance of population establishment at low density.
