Red Is For Hummingbirds, Yellow For Moths

10-07-2006 · ScienceDaily

Biologists at the University of California, San Diego have discovered that the future of red and yellow varieties of a San Diego wildflower may depend on the fates of two different animals. They report in the current issue of the Journal of Evolutionary Biology that monkeyflowers have two different animal pollinators. The red form, common along the coast, is strongly preferred by hummingbirds, while yellow monkeyflowers, found east of I-15, are favored by hawkmoths.

Soccer referees do favor home teams, study shows
10-30-2006 · EurekAlert!
Academics have proved what football (soccer) managers in the English Premiership have been complaining about for years -- that referees are inconsistent and favor home teams.Analyzing over 2,500 English Premiership matches, researchers discovered that referees were statistically more likely to award yellow and red cards against the away team -- even when home advantage, game importance and crowd size were taken into account.

Anna's hummingbird chirps with its tail during display dives
01-29-2008 · EurekAlert!
Many of the world's smallest hummingbirds, including the West Coast's Anna's and the East Coast's ruby-throated, execute display dives to seduce females and drive away intruders. A characteristic chirp at the bottom of the Anna's dive, thought by many to be vocal, has now been shown to result from a split-second flaring of the tail feathers. UC Berkeley tests prove that tail feather vanes act like a reed in a clarinet to produce the beep.

UC Davis scientists' groundbreaking research: Mate-attracting chemicals
10-27-2006 · EurekAlert!
It's all about "the birds and the bees." And now, "the silkworm moths and the fruit flies."A chemical ecologist and a genetics researcher at the University of California, Davis, have joined forces to trick fruit flies into thinking that silkworm moths are potential mates.Groundbreaking research in the labs of chemical ecologist Walter Leal and genetics researcher Deborah Kimbrell shows that genetically engineered fruit flies responded to the silkworm moth scent of a female.

Protein sciences
03-08-2007 · EurekAlert!
Protein interactions direct cellular functions and their responses to pathogens and are important therapeutic targets. Scientists from the GSF Research Center for Environment and Health have recently developed a method enabling simultaneous visualization of individual proteins and their interactions in living cells. This is achieved by engineering the proteins to constantly emit red or blue fluorescent signals and to produce an additional yellow fluorescent signal upon interaction.

To elude bats, a moth keeps its hearing in tune
12-18-2006 · EurekAlert!
It has been known for over 50 years that moths can hear the ultrasonic hunting calls of their nocturnal predator, the bat. Moth ears are among the simplest in the insect world -- they have only two or four vibration-sensitive neurons attached to a small eardrum. Previously, it was thought that these ears were only partially sensitive to the sound frequencies commonly used by bats, and it would seem likely that by using high ultrasound, bats would make their hunting calls inaudible to moths.

Microsurgery and Super Glue show how antennae aid moth navigation
02-08-2007 · EurekAlert!
Scientists have wondered how four-winged insects most active at low-light times of the day accomplish complex navigational maneuvers, since they lack the structures that help two-winged insects to navigate. New research has demonstrated that, in hawk moths, an organ near the base of the antennae assists in flight control.

Color names: More universal than you might think
10-18-2006 · EurekAlert!
From Abidji to English to Zapoteco, the perception and naming of color is remarkably consistent in the world's languages. Across cultures, people tend to classify hundreds of different chromatic colors into eight distinct categories: red, green, yellow-or-orange, blue, purple, brown, pink and grue (green-or-blue), say researchers in this week's online early edition of the Proceedings of the National Academy of Sciences.

Which came first, the moth or the cactus?
08-13-2007 · EurekAlert!
It's not a good idea to put all your eggs in one basket -- unless you're a senita moth. Found in the parched Sonoran desert, the moths have a rare, mutually dependent relationship with senita cacti, one of only three known dependencies in which an insect actively pollinates flowers for the purpose of assuring a food resource for its offspring. Rice University ecologists are using the relationship to test new theories of community ecology.

Moths mimic sounds to survive

In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study.
