Calling and Spawning Seasons in a Mixed Population of Anurans
Ecology, 1961This work was done to learn the relation between the period in which male anurans vocalize. and the actual tinmes of spawning and to learn the reproductive seasons of a sympatric group of anuran species. Precise knowledge of the reproductive season, including environmentally induced variations, in a group of species that utilize the same breeding pools

The effects of temperature, water level and moon phase on the movements of pikeperch (Sander lucioperca) were studied during pre-spawning and spawning season from April to June. Trends in catches and temperature were removed with linear regression. Cross-correlation analysis showed that temperature change one and two days earlier had the strongest ...

Mackerel egg predation by cannibalism during the spawning season
2004No abstracts are to be cited without prior reference to the author.Consuming one’s own viable offspring is common among species that share the same distribution area for all their different life stages. The objective of this paper is to describe the role of mackerel as prey and as predator in the Cantabrian Sea (ICES Division VIIIc) during its spawning
