Journal ArticleDOI
Senses and signals: evolution of floral signals, pollinator sensory systems and the structure of plant-pollinator interactions.
TL;DR: A concise review of the state of the authors' knowledge on the evolution of floral traits and pollinator sensory perception and how these together shape the structure and organization of pollination networks is provided.
Journal ArticleDOI
Nocturnal Bees Feed on Diurnal Leftovers and Pay the Price of Day – Night Lifestyle Transition
TL;DR: It is predicted that nocturnal bees primarily use night-blooming flowers, show little/no resource overlap with diurnal species and competitive release favors night-time pollen collection for provisioning, and found substantial resource overlap betweennocturnal and diurnal bees.
Journal ArticleDOI
Secondary removal of Myristica fatua (Myristicaceae) seeds by crabs in Myristica swamp forests in India
Shivani Krishna,Hema Somanathan +1 more
TL;DR: In these fragmented swamp forests, secondary removal by crabs retains seeds largely within the swamps, where conditions for their establishment and survival are optimal, and could provide temporal and spatial refugia from seed predators such as rodents in Myristica fatua.
Journal ArticleDOI
Intersexual mimicry and flowering phenology facilitate pollination in a dioecious habitat specialist species, Myristica fatua (Myristicaceae)
Shivani Krishna,Hema Somanathan +1 more
TL;DR: Using a model of honeybee color vision, the distance between the color loci of male and female flowers is found and based on minimum visual angle subtended by these flowers, it is suggested that the two floral sexes cannot be discriminated by bees.
Journal ArticleDOI
Spatiotemporal strategies that facilitate recruitment in a habitat specialist tree species.
Shivani Krishna,Hema Somanathan +1 more
TL;DR: It is found that M. fatua bears few large-sized seeds and fruits for extended periods of time such that few seeds are produced at any point of time, thus escaping detection of seed predators.
