* By Antonio Garza de Yta, Ph.D The importance of increasing domestic markets in countries where aquaculture is developed is increasingly discussed. However, it is necessary to take into account their own realities, as they are completely different. Recently I have been involved in several discussions where the importance of increasing domestic markets in countries […]
I have a weak spot for trees like cherry, plum and apple, you know the ones with these dramatic pink and white flowers every spring. I have a vague idea of planting a small forest with mostly these trees and just let them do their own thing at the back of my property, maybe letting it be a scenic tourist spot to draw in visitors in the future. There’s a park a town over from me that gets a lot of visitors every time the cherry trees bloom, so I was thinking I might be able to do something similar, but on a bigger scale with differently sized trees and a few different varieties to prolong the blooming season. Fruit and wood would mostly be a side product, I just want the flower forest.
But I’m hesitating because I haven’t seen anyone do it before. And it seems like such a simple thing that, if I haven’t seen anybody do it, there’s probably a reason why.
On one hand, nutrients might be a problem. But I’m not envisioning a managed orchard – it doesn’t need to yield the maximum amount of fruit, and whatever I wouldn’t pick would attract animals and birds so nutrients would come in that way without my participation. Other than that, I can’t really think of anything, provided I protect the trees until they’re grown.
From frogs to ferrets, an eye-opening account of the ways we affect the health of other species – and vice versa
Before entering Edinburgh’s Royal Botanic Garden, visitors must walk over disinfecting mats to rid their shoes of bacteria or other pathogens. Next to the mats is a sign whose admonition seems at once both practical and religious: “Cleanse your soles.” Whenever I visit, as I often do, this sign always makes me smile: this ritualised cleaning is an important measure to prevent outbreaks of disease among the garden’s 730 species, but it also seems to be some kind of spiritual act.
Anyone tempted to jump that mat should read Liz Kalaugher’s new book, a wide-ranging, thorough and persuasive investigation of the ways in which we have made non-human animals sick. Her book reads as a kind of shadow history of human endeavour and innovation, tracing the calamitous price that trade, exchange and intensive farming have exacted on everything from frogs to ferrets. It’s a measured and detailed account, but below the calm surface you can hear an anguished cry imploring us to open our eyes and see how our own health is intertwined with that of other species.
Researchers have isolated a giant virus, which was named Jyvaskylavirus. The discovery shows that giant viruses are more common in northern regions than researchers have thought. It also illustrates that there are still many structures whose origins and functions have not been properly studied.
Starch and oils are known as storehouses of carbon in plants. However, the way in which carbon resources are allocated during metabolism in plants remained unknown. Now, however, using a forward genetics approach, researchers have identified that a gene named LIRI1 regulates this process, significantly increasing oil storage in leaves while reducing starch levels. Their findings provide insights into carbon allocation mechanisms, offering the potential for the development of renewable biofuel resources or low-starch foods.
The pedunculate oaks typical of Leipzig’s floodplain forest and other German oak forests are struggling to regenerate in the understorey due to a lack of light. One reason for this is the absence of flooding in floodplain forests. In a two-year oak experiment in Leipzig’s floodplain forest, researchers found that the current tree dieback — caused by drought and pest outbreaks — combined with the thinning of certain understorey species, can actually support oak regeneration.
