Habitat-specific responses in the flowering phenology and seed set of alpine plants to climate variation: implications for global-change impacts
The timing of the snowmelt is a crucial factor in determining the phenological schedule of alpine plants. A long-term monitoring of snowmelt regimes in a Japanese alpine area revealed that the onset of the snowmelt season has been accelerated during the last 17 years in early snowmelt sites but that such a trend has not been detected in late snowmelt sites. This indicates that the global warming ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

Pollinator effects on genotypically distinct soybean cytoplasmic male sterile lines
Poor seed-set limits potential for soybean hybrid seed production. The objective of this study was to evaluate effects of different pollinators on the rate of seed set in three soybean cytoplasmic male sterile (CMS) lines, JLCMS9A, JLCMS82A, and JLCMS89A. The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter ...

Could evolution be our ally when it comes to mosquito control?
Two researchers propose a novel approach to reduce mosquitoes’ human toll without disrupting ecosystems. By the quirks of genetics, some people are natural mosquito bait. In any group of 10, it seems, one person will draw a fury of bites, while the rest get off lightly. Which makes a dreamer wonder: Why not devise a nonhuman target to attract mosquitoes and so reduce the toll of ...

World Bee Day
The 20th of May marks World Bee Day, aiming to raise awareness about the importance of bees in our ecosystem. Bees are vital to pollinate the food we eat as well as the trees and flowers which are habitats for wildlife, thanks to bees we can enjoy a range of foods from apples to coffee. Approximately 75% of the world’s crops depend, to some degree, on pollinators to provide high yields of good ...

Introducing the Sustainability Adaptive ERG
At Adaptive, we aspire every day to create and cultivate a culture of belonging. As a lifelong conservationist and advocate for responsible consumption, for me, bringing my whole self to work means these passions come to the office with me. Since Adaptive’s early years we’ve operated with environmental responsibility at top of mind. Disposal guides developed by lab staff ensure ...

Mutations perturbing petal cell shape and anthocyanin synthesis influence bumblebee perception of Antirrhinum majus flower colour
We wished to understand the effects on pollinator behaviour of single mutations in plant genes controlling flower appearance. To this end, we analysed snapdragon flowers (Antirrhinum majus), including the mixta and nivea mutants, in controlled laboratory conditions using psychophysical tests with bumblebees. The MIXTA locus controls petal epidermal cell shape, and thus the path that incident ...

Desert Year: Robust Economy and Lessons of the Sonoran Agave
Guest Blogger, Energy Efficiency Markets Reposted from Real Climate Economics August 17, 2011 John ‘Skip” Laitner is an economist, enjoying a desert year while on research sabbatical from the American Council for an Energy-Efficient Economy. Skip is discovering some surprising insights from his time in the desert that can inform the way one looks at the economy and social systems. ...
