THE DIVERGENCE OF SOXE GENE FUNCTION DURING VERTEBRATE EVOLUTION
(2014-05-09)
Evolutionary developmental biology (evo-devo) is the study of how developmental mechanisms that shape organisms have changed through evolutionary time. A central question in evo-devo asks how early vertebrates may have ...
TROPHIC CONNECTIONS BETWEEN STREAM AND TERRESTRIAL FOOD WEBS
(2010)
Most animals have complex life histories (CLH) in which an individual's niche shifts through ontogeny. These organisms often cross habitat or ecosystem boundaries as they develop from larvae to adults, coupling energy ...
Phylogenetic and proximate mechanisms affect darter (Percidae: Etheostomatinae) community structure
(2015-05)
Understanding the relative influences of biotic and abiotic mechanisms responsible for generating patterns of community diversity remains a fundamental theme in ecology. Although studies have recovered patterns of community ...
THE WORLD BELOW: HOW RESOURCES AND HABITAT INFLUENCE INSECT COMMUNITIES ACROSS SPACE AND THROUGH TIME
(2019-05-10)
Insects are one of the most abundant, diverse, and ecologically important clades of organisms. They represent up to 5-10 million species, accounting for approximately 46% of the animal biomass on Earth. Yet, despite the ...
Radiation of tribosphenic mammals during the early Late Cretaceous (Turonian) of North America
(2017-12)
Tribosphenic mammals from the medial Cretaceous (encompassing the Cenomanian to the Campanian (~98–80 Ma)) are rare elements of the fauna, typically recovered via bulk sampling and underwater screen washing. Southern Utah ...
Molecular basis of ecdysteroid mediated limb regeneration in the fiddler crab, Uca pugilator
(2014-05)
Regeneration is a biological phenomenon that provides an organism the ability to recapitulate part of embryonic development as an adult. The capacity to regenerate is not limited to any particular group of animals; however, ...
Estimating bird/bat fatality rates and using stable-hydrogen isotopes to assess hoary bat migratory patterns associated with a wind-energy facility in western Oklahoma
(2013)
Offsetting a portion of the energy deficit of the United States with emission-free, renewable energy is driving a rapid increase in the number of wind-power installations across the country. Although wind energy has ...
Aversive learning effect on odor coding in rat's piriform cortex
(2011)
Olfaction, a sense for detecting and discriminating chemical molecules in the environment, is critical for animal survival, reproduction and other adaptive behaviors. The olfactory system is organized in three major stations ...
INSIGHTS FROM LAMPREY INTO DEVELOPMENT AND EVOLUTION OF GLIA AND CRANIAL SENSORY GANGLIA
(2018-05-11)
During evolution, animal nervous systems have become increasingly complex. This complexity is based on the cumulative diversity of neural cells and the emergence of new nervous system structures. Among animals, vertebrates ...
Ornamental nestling mouth coloration and parental care in house sparrows
(2010)
Dependent offspring across taxonomically-diverse lineages use behavioral, vocal, chemical, and morphological traits to attract parental care. Such offspring solicitations are often hypothesized to evolve as a means of ...
