Global Trends in the Status of Bird and Mammal Pollinators [PDF]

, 2015
Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals.

Butterfly Conservation in China: From Science to Action

Insects, 2020
About 10% of the Earth’s butterfly species inhabit the highly diverse ecosystems of China. Important for the ecological, economic, and cultural services they provide, many butterfly species experience threats from land use shifts and climate change ...

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Identifying Barriers to Citizen Scientist Retention When Measuring Pollination Services

Citizen Science: Theory and Practice, 2018
'Pollination Investigators' is a citizen science program designed to quantify the pollination service provided within home gardens. The goal of our initial study year was to develop and evaluate an experimental protocol using a survey to gather ...

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

American Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

The unique morphological basis and repeated evolutionary origins of personate flowers in Penstemon

American Journal of Botany, EarlyView.
Abstract Premise Adaptive radiation in ecologically and morphologically diverse plant lineages presents an opportunity to investigate the rapid evolution of novel floral traits. While some types of floral traits, such as flower color, are well characterized, other types of complex morphologies remain understudied.

Pollen foraging preferences in honey bees and the nutrient profiles of the pollen

Scientific Reports
Honey bees are important insect pollinators that provide critical pollination services to fruit and nut crops in the US. They face challenges likely due to pressures associated with agricultural intensification related habitat loss.

The role of pollinator attracting scent in the sexually deceptive orchids Ophrys chestermanii, O. normanii and O. tenthredinifera [PDF]

, 2008
Sexual deception of male bees is one of the most remarkable mechanisms of pollination (Ackermann 1986, Proctor & al. 1996). Flowers of the orchid genus Ophrys mimic females of their pollinator species, usually bees and wasps, to attract males, which try ...
