Biophysical mechanisms for the generation of electrosensory and communication signal in the weakly electric fish Eigenmannia virescens
(2018-05-03)
The weakly electric fish Eigenmannia virescens generates electric organ discharges (EODs) to navigate and communicate. The EODs are brief monophasic voltage pulses with brief inter-pulse intervals, resulting in a sinusoidal ...
Multi-scale effects of habitat alteration on stream fishes: from genotypes to communities
(2011)
Understanding how evolutionary and ecological processes interact with altered habitats at these various scales will be a major challenge to conservation biologists in the coming decades, and will be crucial for predicting ...
Effects of fish density, identity, and species richness on stream ecosystems.
(2005)
Stream ecosystem properties and functions are important because they provide services such as water purification, oxygen production, and carbon fixation that help sustain life. Aquatic organisms can affect these properties ...
Parent-offspring recognition in cave swallows
(2013)
Natural selection favors investment in genetic relatives over giving such aid indiscriminately. Parental care is often easily directed only towards genetic relatives, but under some circumstances, this task can be problematic. ...
EVOLUTIONARY AND DEVELOPMENTAL ORIGINS OF THE VERTEBRATE NEURAL CREST: INSIGHTS FROM LAMPREYS INTO 500 MILLION YEARS OF VERTEBRATE EVOLUTION
(2020)
Much of what distinguishes the vertebrates from their invertebrate relatives is a small group of embryonic cells known as the neural crest. In all vertebrate embryos the neural crest gives rise to a dazzling array of cell ...
Life with and without sex :
(1980)
Nepotistic behavior was never observed among parthenogenetic whiptails for several possible reasons. First, it appears that members of parthenogenetic whiptail populations are not genetically identical due to independent ...
Ecological drivers of species radiations in the genus Limia (Teleostei, Poeciliidae) in the West Indies
(2021-05-14)
The archipelagoes of the West Indies in the Caribbean represent geographically composite regions that provide ideal settings to study the evolution of a very distinctive biota. The combination of complex geological events ...
Acute toxicity of hydrogen sulfide to fish during harvesting operations on commercial catfish farms :
(1980)
Unconsumed fish food apparently resulted in the high sulfide concentrations seen near the feeding area in May or June and September of both years. Dissolved sulfide concentrations decreased near the feeding area in July ...
