Fish predation on a Daphnia hybrid species complex: A factor explaining species coexistence?
Recent studies on the life histories of Daphnia hybrids and their parental species have revealed that hybrids can combine an intermediate size with a relatively high reproductive rate, which might explain their success in many European lakes. Based on this information, we formulated the temporal hybrid superiority hypothesis to explain the coexistence of parental species and their hybrids. Our ...
متن کاملSpecies coexistence in a food web with intraguild predation
We studied species coexistence in a protist community consisting of a bacterial resource, five protist consumers, and an intraguild predator, Blepharisma americanum. Spatial heterogeneity was manipulated by constructing spatial arrays of interlinked bottles. In the heterogeneous treatment species were permitted to disperse naturally between bottles whereas in the homogenous treatment half the w...
متن کاملDaphnia Species Invasion, Competitive Exclusion, and Chaotic Coexistence
The cladoceran Daphnia lumholtzi has invaded many US rivers and lakes. To better understand the ecological factors and consequences associated with D. lumholtzi invasion, we carried out a microcosm experiment evaluating competition of D. lumholtzi with a widespread native daphnid, D. pulex. We applied two light treatments to these two different microcosms and found strong context-dependent comp...
متن کاملA Review of Fish Taxonomy Conventions and Species Identification Techniques
Taxonomists, ecologists, geneticists or researchers from other biological fields who wish to adopt fish as a constituent of their studies often become discouraged when they find that ichthyology is a complex subject. In fish-based studies, the failure to recognize fishes as distinct biological units can lead to wrong diagnosis. Hence, this review paper attempts to clarify and discuss the latest...
متن کاملTranscontinental Phylogeography of the Daphnia pulex Species Complex
Daphnia pulex is quickly becoming an attractive model species in the field of ecological genomics due to the recent release of its complete genome sequence, a wide variety of new genomic resources, and a rich history of ecological data. Sequences of the mitochondrial NADH dehydrogenase subunit 5 and cytochrome c oxidase subunit 1 genes were used to assess the global phylogeography of this speci...
