Complexity of coral interactions: Influence of time,location of interaction and epifauna 总被引:1,自引:0,他引:1
The potential role of competition for space in a community depends on the arrangement of interaction relationships. A survey (255 m2) of the interactions between corals (Scleractinia) on a Caribbean reef (depth 10–30 m) indicated the outcome of 17–35% of the aggressive and defensive interactions to be unpredictable. Experiments on the reef (depth 7–13 m) with pairs of interacting corals — Madracis mirabilis (Duchassing & Michelotti), Agaricia agaricites (L), Montastrea annularis (Ellis & Solander), Eusmilia fastigiata (Pallas) — showed that, after the initial contest through extracoelenteric digestion, there are at least two additional processes which can result in a reversal of dominance: interference by epifauna and sweeper tentacle development. Moreover, the impact of extracoelenteric digestion and the extent of sweeper tentacle development varied over the surface of the corals. Employing laboratory and field experiments to distinguish between the impact of extracoelenteric digestion, epifauna behaviour and sweeper tentacles, we show the three processes combined to explain the coral interaction process in toto. The outcome of the interaction process on the reef depends on numerous, partly unpredictable, variables, including mode of contact and effects of position. Consequently, patterns of community organization resulting from spatial competition will be slow to emerge and easily erased prematurely by disturbances. 相似文献

Summary. In the marine polychaete Nereis succinea (Frey & Leuckart 1847) a sex pheromone was isolated from the coelomic fluid of sexually mature females and identified by
NMR studies and independent synthesis. This pheromone is released by the females during reproduction together with eggs and
coelomic fluid into the free water column and induces sperm release of surrounding males. Its structure was ascertained as
L-cysteine-glutathione disulfide. It exhibited a response threshold of 0.6 · 10−7 M.

Genetic divergence and phylogenetic inferences in five species of Mugilidae (Pisces: Perciformes) 总被引:4,自引:0,他引:4
Allozyme electrophoresis was used to compare the genetic divergence of global populations of Mugil cephalus Linnaeus, 1758 and two congeneric [M.␣curema Cuvier & Valenciennes, 1836; M. gyrans (Jordan & Gilbert, 1885)] and two more distantly related [Liza ramada (Risso, 1826); Xenomugil thoburni (Jordan & Starks, 1896)] species on the basis of 18 enzyme loci. The amount of genetic divergence among the species examined
is in agreement with their present systematic status, the differences being larger among non-congeneric species than among
species of the same genus. Intraspecific genetic distances in M. cephalus (average Nei's D= 0.154), although higher than those reported for conspecific populations of fish, appear to be small when compared to the
interspecific values among mugilid species (0.821 ≤ Nei's D ≤ 1.744). Phylogenetic trees obtained by genetic distance methods and discrete character parsimony analysis were of similar
topology, except for the relationships within the genus Mugil and for the arrangement of M. cephalus populations.

I develop a differential game between an oil cartel and an importer investing in research and development (R&D) to reduce the cost of a green substitute to oil. In equilibrium, the cartel is forced to deter the substitute, which thus imposes a price ceiling falling over time. Credible carbon taxes are below the Pigovian level, implying the importer cannot internalise the full pollution externality, much less capture resource rents. Without carbon pricing, the importer curtails long-run pollution using a costly R&D programme. Normatively, climate policy will be more expensive if relying on green R&D programmes only. 相似文献

The extent to which environmental regulatory institutions are either ‘green’ or ‘brown’ impacts not just the intensity of regulation at any moment, but also the incentives for the development of new pollution-control technologies. We set up a strategic model of R&D in which a polluter can deploy technologies developed in-house, or license technologies developed by specialist outsiders (an ‘eco-industry’). Polluters exert R&D effort and may even develop redundant technologies to improve the terms on which they procure technology from outside. We find that, while regulatory bias has an ambiguous impact on the best-available technology, strategic delegation to systematically biased regulators can improve social welfare. 相似文献

A fashionable field of enquiry – the relationship between expressed attitudes and actual behaviour in the context of sustainable development – is complex (Staats et al. 2004) and difficult to apply in a policy-relevant manner (Aall and Norland 2005). However, recent research indicates that the use of a household diary can be beneficial in helping to quantify household environmental impact, in educating householders about their impact, and in identifying major ‘behavioural turning points’, where householders may focus efforts to reduce their environmental impact (Hunter et al. 2006). In other words, the use of a diary by householders is a potentially powerful tool in encouraging and facilitating desired behavioural change. This paper reports on the initial findings of an innovative study that assessed the use of a household diary approach as a means of framing and collecting household environmental data and, critically, as an educational vehicle for bringing about behavioural change. Based on the initial findings, it is clear that there is some potential to develop practical policy measures that empower householders by allowing them to better grasp their environmental impact and, consequently, recoup positive implications in terms of financial savings (e.g. reducing the amount of food thrown out) and health benefits (e.g. more walking/cycling). 相似文献
