Life history traits: a possible cause for the higher frequency of occurrence ofZannichellia pedunculata than ofZannichellia obtusifolia in temporary marshes
TL;DR: The inability to reproduce in the autumn, and the negative influence of desiccation on the rate of germination and percentage germination, can explain why Zannichellia obtusifolia is uncommon in the Camargue marshes which are subject to frequent and irregular periods of drying out.
Journal ArticleDOI

Journal ArticleDOI
Expected and unexpected effects of waterbirds on Mediterranean aquatic plants
Guillaume Gayet,Nicolas Croce,Patrick Grillas,Carole Nourry,Clemence Deschamps,Pierre Defos du Rau +5 more
TL;DR: The combined effect of waterbirds on Z. noltii is thus dual, mainly favouring its development by reducing competing macroalgae but conversely mitigating it through direct impact at both ends of the growing season.
Journal ArticleDOI
Oviposition plant choice maximizes offspring fitness in an aquatic predatory insect
TL;DR: The results indicate that adults choose oviposition plants maximizing offspring fitness (higher hatching success and faster embryonic development) in the damselfly Lestes macrostigma that prefers the plant Bolboschoenus maritimus.
Journal ArticleDOI
Livestock disturbances in Mediterranean temporary ponds: A mesocosm experiment with sheep manure and simulated trampling
Maarten Van den Broeck,Laila Rhazi,Aline Waterkeyn,Mohammed El Madihi,Patrick Grillas,Jamie M. Kneitel,Luc Brendonck,Luc Brendonck +7 more
TL;DR: In this article, the effects of livestock grazing on faunal and floral communities of Moroccan temporary ponds were investigated. And they found that sheep-simulated trampling and nutrient input decreased hatching invertebrate and plant richness, while lasting effects on water quality and actively colonising communities were limited.
