Frontiers in Plant Science, 2018 The presence of nectarless flowers in nectariferous plants is a widespread phenomenon in angiosperms. However, the frequency and distribution of nectarless flowers in natural populations, and the transition from nectariferous to nectarless flowers are ...

Assessing risks and benefits of floral supplements in conservation biological control [PDF]
, 2010 The use of flowering field margins is often proposed as a method to support biological control in agro-ecosystems. In addition to beneficial insects, many herbivores depend on floral food as well.

Land birds on atolls: diversity, origin, and function
Biological Reviews, EarlyView.ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates the causal mechanisms by which responsible leadership (RL) promotes sustainable agritourism development in the Mekong Delta, Vietnam. Using focus groups and multiple case studies across five exemplary agritourism operations, we examine how RL operates across multiple levels to influence sustainable agritourism outcomes.

Ecography, EarlyView.Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Simple Model of Learning and Collective Decision Making during Nectar Source Selection by Honey Bees [PDF]
, 2005 Swarm Robotics is an area of active research interest where groups of robots coordinate and perform collective tasks. Existing ap- proaches to Learning and Collective Decision Making amongst a group of robots is complex.

Ecography, EarlyView.Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Is there a diel pattern to nectar secretion in the Red Bloodwood Corymbia gummifera? [PDF]
, 2013 Nectar secretion was measured at 6-h intervals over a 24-h period in flowers of the Red Bloodwood, Corymbia gummifera (family Myrtaceae). Secretion varied among time periods and among trees. There was no clear diurnal or nocturnal pattern.
