Bringing together significant work on all aspects of the subject, Behavioral Ecology is broad-based and covers both empirical and theoretical approaches. Studies on the whole range of behaving organisms, including plants, invertebrates, vertebrates, and humans, are included.
Built-in billboards: Male bluefin killifish signal different things with different fins
They help fish swim, but fins also advertise a fish's social standing and health. In a new study, researchers report that for the male bluefin killifish (Lucania goodei), each colorful fin presents its ow ...
Mice nest together to confuse paternity and reduce infanticide
It is a cruel world out there, particularly for young animals born into social groups where infanticide occurs. This dark side of evolution is revealed when adults – often males – kill offspring to promote ...
Monkeys fear big cats less, eat more, with humans around
Seed beetle 'kicks' sign of antagonistic coadaptation
New research from The University of Western Australia's Centre for Evolutionary Biology has found evolutionary kicking behaviour of female seed beetles (Callosobruchus maculatus) has been 'hi-jacked' by males ...
Researchers find fish 'yells' to be heard over human made noise
Male St. Andrew's Cross spiders sniff web pheromones to determine suitability of female mates
Fight or flight? Vocal cues help deer decide during mating season
Previous studies have shown that male fallow deer, known as bucks, can call for a mate more than 3000 times per hour during the rut (peak of the mating season), and their efforts in calling, fighting and ...
Sexual selection may result in bigger-billed male birds
(Phys.org) —To female coastal plain swamp sparrows, male bill size matters.
Beetles who socialise more spend more time judging their opponents
Burying beetles that have been in contests for food and resources previously will spend more time assessing their opponent but this cautious behaviour doesn't mean they're more likely to win, say scientists.
Personality interactions between animals may dictate outcomes in the wild
Examining the varying personality types of multiple animal species at once—in addition to common single-species studies—could help biologists better predict ecological outcomes, according to a recent University of Pittsburgh ...
Researchers find mother beetles eat young that beg too much
Bright birds make good mothers
Female blue tits with brightly coloured crowns are better mothers than duller birds, according to a new study led by the University of York.
Sexual selection in the sea
Biologists have uncovered new insights into how the male sexual behaviour of the peculiar southern bottletail squid is primed to produce the greatest number of offspring.
Researchers find lizards' frilled neck is more than just for show
(Phys.org) —Researchers have discovered that the brightly coloured frills of the iconic Australian frillneck lizard (Chlamydosaurus kingii) can be used to predict the animals fighting ability.
In birds, personalities can be a question of weather
We all know about people's personalities, and anyone with a dog or a cat will also tell you about their temperaments. More surprising, though, is how many others, from octopuses to frogs and even spiders ...
