Thermoregulatory constraints on behavior: patterns in a neotropical dragonfly assemblage

Fish assemblage in a semi-arid Neotropical reservoir: composition, structure and patterns of diversity and abundance.

The aim of this study was to analyse the composition, structure and spatial and temporal patterns of diversity and abundance of the ichthyofauna of the Santa Cruz Reservoir in semi-arid Brazil. Data were collected quarterly at eight sampling locations on the reservoir between February 2010 and November 2011 using gillnets from 12- to 70-mm mesh that were left in the water for 12h00min during th...

Patterns of ventilation in dragonfly larvae.

Respiration in the aquatic larvae of anisopteran dragonilies is of interest from a comparative point of view in that it utilizes a tidal ventilation mechanism in an aquatic medium. In most animals where water is the respiratory medium the flow over the respiratory surfaces is generally undirectional and this probably requires less energy for the extraction of a given amount of oxygen. Tidal or ...

Effects of Zebra Mussel Colonization on Dragonfly Larvae Burying Behavior

Diel activity and reproductive isolation in a diverse assemblage of Neotropical skippers (Lepidoptera: Hesperiidae)

A sample of over 400 co-occurring species of Neotropical Hesperiidae attracted to artificial lures was used to test for temporal structure among species and explore potential consequences of temporal partitioning within assemblages. Five years of intermittent transect samples at the same site revealed that diel activity was significantly partitioned among subfamilies, genera and species within ...
