Rapid environmental change can threaten even a peaceful Daisyworld

Using mathematical modeling, researchers have discovered that rate-induced tipping, which can happen if an environment changes too fast, can happen even in Daisyworld, a simple daisy-filled ecological model. If the planet heats up or cools down too quickly, all the daisies will go extinct, even if they would otherwise have been able to survive just fine under those conditions. This discovery mirrors similar observations found in other models and observed in real-life ecosystems.

Edible Hedge Ideas


I’m working on creating a new hedge for my garden in Nanaimo on Vancouver Island, and I could really use some advice. I have some specific criteria, and I’m hoping you can help me find the best options.

Here’s what I’m looking for:

Cold-Hardy: The hedge needs to grow well in zone 8a-8b, which means it should be able to withstand mild winters and occasional frost.

Evergreen: I want a plant that keeps its foliage over the winter for year-round privacy and aesthetics.

Fragrant Flowers: I love the idea of having something that smells nice

Edible Berries: I’d prefer something that produces edible berries or fruit (bonus points if they’re tasty or have culinary uses!).

Pest & Disease Resistant: I’m looking for something that is low-maintenance and resistant to common pests and diseases.

Height: The hedge should eventually reach around 6 feet tall

Moderate Growth Rate: I’m okay with slower growth, but it should fill in relatively well over time.

Options I’ve Considered:

Pineapple Guava (Feijoa sellowiana) – I’ve been thinking about this one since it meets many of my criteria. It’s cold-hardy, evergreen, produces fragrant tropical flowers, and edible fruit. But I’m wondering if it’s a good fit in terms of growth rate and cold tolerance in my zone.

If anyone has suggestions or advice on plants that meet these criteria, I’d greatly appreciate your input!

Thanks in advance! 😊

Washington coast


I recently purchased a half acre on the Washington coast, there is good healthy soil, lots of moisture and tons of huckleberries and blackberries and on the property. I have plans to add additional berries and herbs and flowers as we move into the spring/summer. I’m generally open to advice, but am specifically looking for advice on what to do with this wood pile. It’s rotten through, and while I’ve had success burying smaller piles of wood and planting on top, I’m stuck on how big this pile is.

Should I burry the pile of wood as is? Attempt to maneuver it into smaller piles to bury? What should I plant on top?

Also, since I’m here, what’s the best way to get rid of ivy beyond pulling? 🙃

AquaFarm, NovelFarm and AlgaeFarm: growth and increased attendance reward the events return


February 18, 2025 – The eight edition of AquaFarm successfully ended, marking the return of the unified event with NovelFarm and AlgaeFarm – respectively at theri sixth and fourth editions – under a single trade event at the Pordenone exhibition centre. The decision to bring together the three events has generated strong interest among operators and the public, leading to a significant increase in attendance: visitors increased by 30% compared to the 2024 edition.

The event saw the participation of over 110 exhibitors (on 7000 m2 of exhibition space) from Italy and abroad, confirming the central role of Pordenone Fiere as a point of reference for the sectors of aquaculture, innovation in plant and algae cultivation. The conference programme recorded an extraordinary participation, with 20 sessions and over 150 speakers who discussed the most current issues of the sector, from sustainability to food safety, up to new technologies for production and farms management.

Thanks to the collaboration with ICE Agency, this edition welcomed a delegation of 30 top international buyers from Brazil, North Africa, the Balkans and Greece, joined by other delegations, especially from the Baltic countries.

Renato Pujattti, President of Pordenone Fiere, stated: “We are proud that also this year the Ministry of Agriculture, Food Sovereignty and Forestry has chosen to participate in Aquafarm to reaffirm its commitment to promoting the fish sector. Masaf was present at the fair witha dedicated exhibition area, a conference room and a show cooking arena to promote the quality and sustainability of Italian fish products. Conferences, meetings and in-depth discussions addressed the crucial challenges of the sector: from the effects of climate change to the fight against ‘fake seafood’, up to the management of invasive species. Aquafarm, thanks to the collaboration with Masaf, confirms itself as an opportunity for operators to discuss innovation and development, and for visitors and young people to learn about an extraordinary sector”.

Among the moments of greatest interest for AquaFarm, the sessions dedicated to sustainability in aquaculture, energy self-sufficiency and innovative solutions for the decarbonisation of the sector stand out. We also underline the sessions “Aquaculture and added value fishing products” with the leaders of the fishing supply chain as protagonists, along with the “EU-FEAMPA” session on European innovations that impact the sector.

NovelFarm attracted great public attention for the opening theme ‘Indoor farming in Italy: technological greenhouses, vertical farms, urban agriculture between regulations, investments and the market’, where players, consultants and representatives of the academic world took turns to discuss the evolution of controlled agriculture in urban environments.

Another moment of great interest was, with the closing of AlgaeFarm, characterised by the round table on the future of the algae supply chain, which explored the opportunities and challenges for the sector, from the food and the pharmaceutical field.

Matteo Leonardi, President of API – Associazione Piscicoltori Italiani, (Italian Fish-Farmers Association) declared: “These two days of AquaFarm 2025 that have just ended have been intense and extraordinary. Full of meetings, exchanges, emotions; we participated in conferences, hosted moments of dialogue, offered the delicacies of Italian aquaculture, trying to highlight the diversity of the species farmed. Two special moments were the delivery of the Davide Menozzi Award and the presentation of the first manual on the well-being of farmed fish. A huge thank you therefore goes to the members, professionals, friends, visitors and organisers of AquaFarm, for continuing on the path towards an aquaculture capable of offering healthy and sustainable food for all”.

During NovelFarm, news arrived from the United States of the death of Dickson Despommier, the recognized father of the modern concept of Vertical Farm, divulged in the famous 2010 book ‘The Vertical Farm: Feeding the World in the 21st Century’. The book, reprinted in numerous editions, is credited, by all entrepreneurs and professionals in the sector, as the source of inspiration that gave life to a global cultural and economic movement. Dickson inaugurated the first edition of AquaFarm, which included conference events, later evolved into NovelFarm, with a memorable presentation that marked an era in our country, visited for the first time by the American luminary. The NovelFarm team and the entire Italian soilless community celebrates and remembers him with gratitude and affection.

AquaFarm, NovelFarm and AlgaeFarm therefore confirm themselves as an essential event for the sector, capable of attracting more and more operators and the public thanks to a format that combines exhibition, high-level professional updating and business opportunities.

On the official website of the event, you can consult the detailed programme where the presentations and the proceedings of the conference sessions will be published shortly.

The appointment is for February 18 and 19 2026, with the ninthedition of AquaFarm, which will always be held at Pordenone Fiere, still in a unified format with NovelFarm and AlgaeFarm.

Native plums


Plum trees native to America. American plum, Flat woods plum, Hortulan plum, Wildgoose plum, Chickasaw plum and Mexican plum are all native to northern Alabama. They are important plants that feed many animals and pollinators and prevent soil erosion. They can grow in extreme drought, extreme flood, and wildfire conditions. The fruit is edible and delicious for many of the species excluding the Wildgoose plum which is likely to be poisonous due to cyanide content.
