Moonlight Can Be A Benefit For Some Prey Species
2013-10-22 17:12:37

Lee Rannals for redOrbit.com – Your Universe Online According to a new study published online recently in the Journal of Animal Ecology, not all animal species are negatively affected by moonlight. One prevailing theory in ecology is that moonlight increases predation risk, but Laura Prugh, a wildlife biologist at the University of Alaska, Fairbanks, says that is not always the case. "Ecologists have long viewed the darkness of a moonless night as a protective blanket for...

Evidence Found To Support Nocturnal Bottleneck Theory
2012-11-01 09:33:36

April Flowers for redOrbit.com - Your Universe Online Most species of diurnal mammals have retained the imprint of nocturnal life in their eye structures since the age of dinosaurs. According to a new study from The University of Texas at Austin and Midwestern University, anthropoid primates - including humans, monkeys and apes - are the only groups that deviate from this pattern. This study is the first to provide a large-scale body of evidence for the "nocturnal bottleneck theory,"...

Nocturnal bulldog ants are not daunted by low temperatures or neighbouring ants, adopting a clockwork-like hunting schedule throughout the year, a new study reveals. Research conducted by The Vision Centre and The Australian National University shows that the nocturnal insects' activity times are not influenced by seasons, temperature tolerance or competition with their neighbours, but by sunset time. "Our previous observations had shown that different species of bulldog and jack jumper ants...

An international collaboration led by a University of Pennsylvania anthropologist has shown that environmental factors, like temperature and light, play as much of a role in the activity of traditionally nocturnal monkeys as the circadian rhythm that regulates periods of sleep and wakefulness. The study also indicates that when the senses relay information on these environmental factors, it can influence daily activity and, in the case of a particular monkey species, may have even produced...

Reporting in the online, open-access journal PLoS ONE April 8, Vincenzo Penteriani and Maria Delgado of the Estacion Biologica de Doñana, Spain, describe the evolution of white throat badges in association with dawn and dusk vocal signals in certain species of nocturnal bird, which maximize the potential for these species to communicate during hours when light is low. Previous research has suggested that visual communication is important only for diurnal species of bird,...

Animal Planet has announced plans to air Night, a new series about the world's most elusive nocturnal animals. The show, for which 31-year-old animal trainer and behaviorist Brandon McMillan will serve as host, is set to debut April 8. I think it's in our nature to be afraid of the dark, McMillan said in a statement. When we're kids, we're taught that monsters such as werewolves and vampires come out at night, but this show examines the real nocturnal animals -- and sometimes they're just as...

- Host Brandon McMillan Creeps and Crawls His Way to the World's Most Elusive Nocturnal Animals on April 8 - SILVER SPRING, Md., March 5 /PRNewswire/ -- Since the dawn of time, man has feared what happens when the lights go out. From the shivers down our spines when coyotes howl to the involuntary jumps when snakes hiss and the uncontrollable urge to run when confronted with bright, beady eyes, nighttime is about the unknown, and it scares us to death. Tapping into these primal fears,...

The West European Hedgehog (Erinaceus europaeus), or simply the European hedgehog, is a hedgehog species found throughout the Palaearctic region. It is not found in the Himalayas and North Africa. It is not commonly found above 60°N in latitude. The only exceptions are Finland, Sweden and the Northwestern-most parts of Russia. This hedgehog is about 7.87 in (20 cm) long. It lives in woodland, farmland and suburban areas. It is nocturnal, and if alarmed will roll itself into a ball....
