Changes in water chemistry can disable plankton prey defenses.
The effectiveness of antipredator defenses is greatly influenced by the environment in which an organism lives. In aquatic ecosystems, the chemical composition of the water itself may play an important role in the outcome of predator-prey interactions by altering the ability of prey to detect predators or to implement defensive responses once the predator's presence is perceived. Here, we demon...
متن کاملInducible defenses in prey intensify predator cannibalism.
Trophic cascades are often a potent force in ecological communities, but abiotic and biotic heterogeneity can diffuse their influence. For example, inducible defenses in many species create variation in prey edibility, and size-structured interactions, such as cannibalism, can shift predator diets away from heterospecific prey. Although both factors diffuse cascade strength by adding heterogene...
متن کاملOn the Seasonal Changes in the Surface Water Chemistry of Museum Lake, Thiruvananthapuram, Kerala, India
The surface water chemistry of Thiruvananthapuram Museum Lake was carried out in the period of February 2013 to January 2014. Correlation study of the parameters and overall CCME WQI (Canadian Council of Ministers of the Environment Water quality Index) was also prepared in the study for the lake water. The parameters analysed are cations such as Ca2+, Na+, Mg2+ and K+ and the anions like PO4-,...

daughters. However, our finding that α α-males sired their daughters' offspring less frequently than non-daughters' offspring remains highly significant when the analysis is restricted to the 34 offspring known to have been born to non first time mothers (Fisher's exact p = 0.0003). A third alternative explanation for our findings is that father–daughter matings are not avoided, but when they ...
