Intense Lawn Mowing Lowers Biodiversity, Favors Pests

By Neha Jain @lifesciexplore  Looks can be deceiving: a uniformly well-mowed lawn might look good, but ecologically, it is not desirable. According to a recent study that analyzed the results of many studies on lawn mowing, more intensely mowed lawns showed lower plant and insect diversity and a greater abundance of pests.  According to the researchers, adopting low-intensity lawn management would bring about a host of environmental benefits including cutting down on greenhouse gas emissions, lowering the prevalence of pests, increasing pollinators and plant diversity, and saving costs.  Less is…

Parasitic Plant Has Edge in Evolutionary Arms Race

By Cameron Duke (@DukeofCam) The relationship between a parasite and its host can be a contentious one. Their interests are in direct conflict with one another, so each is always trying to circumvent the other’s plan. This is often thought of as an evolutionary “arms race.” In this ongoing competition, a parasite evolves a more efficient way to prey on the host, and the host adapts in response. These successive adaptations can lead to complex life cycles and intimate species-specific relationships.  New research out of Penn State, conducted by Michael…

Medicinal Plants to Nourish the Soul

White sage. Peyote. Opium Poppy. African Dream Root. What do all these species have in common? These are all plants that serve both medicinal and spiritual roles in cultures across the world. Plants have long since played important roles in human experience since time immemorial. Plants have provided civilization with food, shelter, tools, and the earliest form of health care. It is from the plant kingdom that people began developing the first medicines. Foxgloves, from the genus Digitalis, native to Europe, Asia, and northwestern Africa, were the original sources of…

Steroid Hormones Protect Cotton from Drought

By Radhika Desikan As you are reading this, chances are that you are wearing something made of cotton, or have come in contact with some cotton fabric today. Cotton accounts for nearly half of all clothing material in the world. Cotton plants date back to prehistoric times; there is evidence of cotton farming from around 5000 BC in the Indian subcontinent. Cotton fabric is made of cotton fibres, which grow in the protective cases (bolls) around the seeds of the cotton plant (Gossypium hirsutum). However, it is not just the…

An Evolutionary Approach to Conserving Plant Habitats

By Mackenzie Myers (@thetiniestnail) To conserve plant habitats, a traditional approach to biodiversity—species richness, or saving as many species as possible—might not be the most effective route. Instead, vulnerable landscapes might be better served by a quality-over-quantity mindset, a recent paper from a team of UC Berkeley scientists suggests. Think of going into a grocery store. On a budget and with limited cooking time, shoppers probably don’t buy the first dozen random ingredients they see on the shelf. Rather, they find it more practical to shop deliberately, perhaps by looking…

Plants Communicate with Neighbors in Response to Touch

By Radhika Desikan How well do you and your neighbour know each other? Chances are, very little these days. But some living things, including plants, know their neighbours well. According to new research, it appears that what one plant “feels” can also be sensed by its neighbouring plant. Isn’t that remarkable? It is a fact of life that plants do not move from one place to another. Therefore plants, unlike humans, cannot move away from any impending danger, be it a herbivore, a disease-causing microbe, or even the cold and…
