Comparison of fish assemblages in two littoral habitats in a Neotropical morichal stream in Venezuela [PDF]

, 2008
Morichales are lowland streams in South American savannas with riparian forest dominated by the moriche palm (Mauritia flexuosa). We sampled littoral habitats from ten flooded vegetated patches (dominated by Mauritiella aculeate) and six sand banks in ...

Leaf longevity and structure, fruit mass and phenology in 52 cultivated varieties and wild accessions of olive

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although phenology has long been recognized as a critical feature for the adaptation of organisms to their local environment, until recently, phenological events have seldom been considered in the broader context of trait‐based ecology.

Trends in chromosome evolution of neotropical characiform fishes [PDF]

Caryologia, 1994
SUMMARYNeotropical characiform fishes present two main trends of chromosomal evolution: some taxa show a heterogeneous pattern, with an extensive numerical and structural variation while others show a more homogeneous one, with a clear stability in their karyotype macrostructure.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the
