Influence of exploitation on population structure, spatial distribution and reproductive success of dioecious species in a fragmented cloud forest in India
The population structure of three dioecious species, Diospyros montana, Diospyros sylvatica and Garcinia talbotii was studied in a seasonal cloud forest in the Western Ghats of India. In anExpand

Visual ecology of Indian carpenter bees II: adaptations of eyes and ocelli to nocturnal and diurnal lifestyles
Most bees are diurnal, with behaviour that is largely visually mediated, but several groups have made evolutionary shifts to nocturnality, despite having apposition compound eyes unsuited to visionExpand

Visual ecology of Indian carpenter bees I: Light intensities and flight activity
Bees are mostly active during the daytime, but nocturnality has been reported in some bee families. We studied temporal flight activity in three species of carpenter bees (genus Xylocopa) in relationExpand

Nocturnal bees learn landmark colours in starlight
Honeybees, like humans and most other vertebrates, are colour-blind in dim light. Bees are primarily day-active and have apposition compound eyes, the typical eye design of diurnal insects. Most beesExpand

Resolution and sensitivity of the eyes of the Asian honeybees Apis florea, Apis cerana and Apis dorsata
SUMMARY Bees of the genus Apis are important foragers of nectar and pollen resources. Although the European honeybee, Apis mellifera, has been well studied with respect to its sensory abilities,Expand

Motion cues improve the performance of harnessed bees in a colour learning task
The proboscis extension conditioning (PER) is a successful behavioural paradigm for studying sensory and learning mechanisms in bees. Whilst mainly used with olfactory and tactile stimuli, moreExpand

Similar yet different: differential response of a praying mantis to ant-mimicking spiders
Batesian mimics typically dupe visual predators by resembling noxious or deadly model species. Ants are unpalatable and dangerous to many arthropod taxa, and are popular invertebrate models inExpand

Nocturnal Pollination by the Carpenter Bee Xylocopa tenuiscapa (Apidae) and the Effect of Floral Display on Fruit Set of Heterophragma quadriloculare (Bignoniaceae) in India1
Abstract We provide the first data on nocturnal pollination by bees. Heterophragma quadriloculare is a self-incompatible hermaphroditic tree solely pollinated at night by the carpenter bee XylocopaExpand

Foraging strategies and physiological adaptations in large carpenter bees
Large carpenter bees are charismatic and ubiquitous flower visitors in the tropics and sub-tropics. Unlike honeybees and bumblebees that have been popular subjects of extensive studies on theirExpand

Perceptions of priority issues in the conservation of biodiversity and ecosystems in India
We report on the results of a country-wide survey of people's perceptions of issues relating to the conservation of biodiversity and ecosystems in India. Our survey, mainly conducted online, yieldedExpand
