As in many lekking anurans, Italian treefrog males use two mating tactics: they can attract females by calling vigorously
or be satellites, that is, they can remain silent in proximity of a calling male and try to intercept females attracted by
their neighbour. We investigated the factors that affected the expression of this mating tactic. Consistent with the conditional
mating tactic hypothesis, satellites were smaller than average and smaller than their parasitised calling males. They spent
a larger-than-average number of nights at the breeding site, where most of them were also observed calling. Moreover, satellites
showed lower call rates and lower mating success than those of males they parasitise but not lower than those of males they
did not parasitise. Overall, these results, together with those derived from the analyses of the seasonal and spatial distribution
of males, provide evidence for a non-random association between satellites and calling males and are consistent with the hypothesis
that satellites have spectral and temporal acoustic preferences that parallel those of females. By adopting the less-successful
satellite mating tactic, competitively inferior males can nevertheless maximise their potential reproductive fitness by sexually
parasitising the most attractive chorusing males. 相似文献

Eco-hydrological modelling in a highly regulated lowland catchment to find measures for improving water quality 总被引:2,自引:1,他引:1

Water quality modelling in the meso-scale Rhin catchment in the German federal state Brandenburg was done (1) to answer some specific questions concerning identification of point and diffuse sources of nutrient pollution in the catchment, (2) to assess the influences of possible climate and land use changes on water quantity and quality and (3) to evaluate potential measures to be done in order to achieve a “good ecological status” of the river and its lakes as required by the Water Framework Directive (WFD).The Rhin catchment is a typical highly regulated lowland river basin in Northern Germany. The regulations complicate water quantity and quality modelling in the catchment. The research was done by using the eco-hydrological model SWIM (Soil and Water Integrated Model), which simulates water and nutrient fluxes in soil and vegetation, as well as transport of water and nutrients to and within the river network. The modelling period was from 1981 until 2005. After calibrating the hydrological processes at different gauges within the basin with satisfactory results, water quality (nitrogen and phosphorus) modelling was done taking into account the emissions of different point sources (sewage treatment plants, etc.) and identifying the amount of diffuse pollution caused mainly by agriculture.For suggesting some feasible measures to improve water quality and to reduce diffuse pollution considering possible climate and land use changes, different reasonable scenarios were applied in consultation with the Environmental Agency of Brandenburg (LUA). The study revealed that the amount of water discharge has significant influence on the concentration of nutrients in the river network, and that nitrogen pollution, caused mainly by diffuse sources, could be notably reduced by application of agricultural measures, whereas the pollution by phosphorus could be diminished most effectively by the reduction of point source emissions. 相似文献
