Data from: Unravelling the life history of Amazonian fishes through otolith microchemistry

Theodore W. Hermann, Donald J. Stewart, Karin E. Limburg & Leandro Castello
Amazonian fishes employ diverse migratory strategies, but the details of these behaviours remain poorly studied despite numerous environmental threats and heavy commercial exploitation of many species. Otolith microchemistry offers a practical, cost-effective means of studying fish life history in such a system. This study employed a multi-method, multi-elemental approach to elucidate the migrations of five Amazonian fishes: two ‘sedentary’ species (Arapaima sp. and Plagioscion squamosissimus), one ‘floodplain migrant’ (Prochilodus nigricans) and two long-distance migratory catfishes...

Data from: Initial genetic diversity enhances population establishment and alters genetic structuring of a newly established Daphnia metapopulation

Christopher J. Holmes, Jelena H. Pantel, Kimberly L. Schulz & Carla E. Cáceres
When newly created habitats are initially colonized by genotypes with rapid population growth rates, later arriving colonists may be prevented from establishing. Although these priority effects have been documented in multiple systems, their duration may be influenced by the diversity of the founding population. We conducted a large-scale field manipulation to investigate how initial clonal diversity influences temporal and landscape patterns of genetic structure in a developing metapopulation. Six genotypes of obligately asexual Daphnia pulex...
