Life history strategies, which combine schedules of survival, development, and reproduction,
shape how natural selection acts on species' heritable traits and organismal fitness …

Fish conservation in South America is a pressing issue. The biodiversity of fishes, just as
with all other groups of plants and animals, is far from fully known. Continuing habitat loss …

Most large rivers in South America are fragmented by large dams, and a common
management strategy to mitigate impacts has been construction of fish passes. Recent …

Interspecific patterns of fish life histories were evaluated in relation to several theoretical
models of life-history evolution. Data were gathered for 216 North American fish species (57 …

THE EVOLUTIONARY STRATEGIES THAT SHAPE ECOSYSTEMS In 1837 a young Charles
Darwin took his notebook, wrote “I think”, and then sketched a rudimentary, stick-like tree …

Food webs in nature have multiple, reticulate connections between a diversity of consumers
and resources. Such complexity affects web dynamics: it first spreads the direct effects of …

Recent studies have increasingly demonstrated the widespread existence of spatio-
temporal variations in the abundance and distribution of species of freshwater fishes …

Scientists and resource managers need to know life history parameters (eg, average
mortality rate, individual growth rate, maximum length or mass, and timing of maturity) to …

The flood regime is the most important force determining seasonality in neotropical rivers. In
the Upper Paran River floodplain, it is the primary factor influencing biological processes …

Life history theories attempt to explain the evolution of organism traits as adaptations to
environmental variation. A model involving three primary life history strategies (endpoints on …
