Cues of being watched enhance cooperation in a real-world setting Tập 2 Số 3 - Trang 412-414 - 2006
Melissa Bateson, Daniel Nettle, Gilbert Roberts
We examined the effect of an image of a pair of eyes on contributions to an honesty box used to collect money for drinks in a university coffee room. People paid nearly three times as much for their drinks when eyes were displayed rather than a control image. This finding provides the first evidence from a naturalistic setting of the importance of cues of being watched, and hence reputatio...... hiện toàn bộ The scaling of green space coverage in European cities Tập 5 Số 3 - Trang 352-355 - 2009
Richard A. Fuller, Kevin J. Gaston
Most people on the planet live in dense aggregations, and policy directives emphasize green areas within cities to ameliorate some of the problems of urban living. Benefits of urban green spaces range from physical and psychological health to social cohesion, ecosystem service provision and biodiversity conservation. Green space coverage differs enormously among cities, yet little is known...... hiện toàn bộ First human-caused extinction of a cetacean species? Tập 3 Số 5 - Trang 537-540 - 2007

The Yangtze River dolphin or baiji (
Lipotes vexillifer
), an obligate freshwater odontocete known only from the middle-lower Yangtze River system and neighbouring Qiantang River in eastern China, has long been recognized as one of the world's rarest and most threatened mammal species. The status of the baiji has not been inve...... hiện toàn bộ Anthropogenic noise affects risk assessment and attention: the distracted prey hypothesis Tập 6 Số 4 - Trang 458-461 - 2010
Alvin Aaden Yim-Hol Chan, Paulina Giraldo-Perez, Sonja M. Smith, Daniel T. Blumstein
Many studies have focused on the effects of anthropogenic noise on animal communication, but only a few have looked at its effect on other behavioural systems. We designed a playback experiment to test the effect of noise on predation risk assessment. We found that in response to boat motor playback, Caribbean hermit crabs (Coenobita clypeatus) allowed a simulate...... hiện toàn bộ Things fall apart: biological species form unconnected parsimony networks Tập 3 Số 5 - Trang 509-512 - 2007
Michael W. Hart, Jennifer M. Sunday
The generality of operational species definitions is limited by problematic definitions of between-species divergence. A recent phylogenetic species concept based on a simple objective measure of statistically significant genetic differentiation uses between-species application of statistical parsimony networks that are typically used for population genetic analysis within species. Here we...... hiện toàn bộ Street lighting changes the composition of invertebrate communities Tập 8 Số 5 - Trang 764-767 - 2012
Thomas W. Davies, Jonathan Bennie, Kevin J. Gaston
Artificial lighting has been used to illuminate the nocturnal environment for centuries and continues to expand with urbanization and economic development. Yet, the potential ecological impact of the resultant light pollution has only recently emerged as a major cause for concern. While investigations have demonstrated that artificial lighting can influence organism behaviour, reproductive...... hiện toàn bộ Individual specialists in a generalist population: results from a long-term stable isotope series Tập 6 Số 5 - Trang 711-714 - 2010
Hannah B. Vander Zanden, Karen A. Bjorndal, Kimberly J. Reich, Alan B. Bolten
Individual variation in resource use has often been ignored in ecological studies, but closer examination of individual patterns through time may reveal significant intrapopulation differences. Adult loggerhead sea turtles (
Caretta caretta
) are generalist carnivores with a wide geographical range, resulting in a broad isotop...... hiện toàn bộ Female mice respond to male ultrasonic ‘songs’ with approach behaviour Tập 5 Số 5 - Trang 589-592 - 2009
Kurt Hammerschmidt, Konstantin Radyushkin, Hannelore Ehrenreich, Julia Fischer
The ultrasonic vocalizations of mice are attracting increasing attention, because they have been recognized as an informative readout in genetically modified strains. In addition, the observation that male mice produce elaborate sequences of ultrasonic vocalizations (‘song’) when exposed to female mice or their scents has sparked a debate as to whether these sounds are—in terms of their st...... hiện toàn bộ
