Many people ask how they can support me as a new author

The best way right now: buy the book on Amazon and PLEASE leave a review

Reviews help the algorithm make the book visible to more early-career researchers
To reach ECRs, I need your reviews🙂

Tree-planting is always good, right? Well, it turns out that a tree planted in the wrong place can actually have a negative impact on the climate. That’s why a research team with scientists from The Nature Conservancy developed maps to help with strategic reforestation for maximum benefit!
New maps help decision-makers factor albedo into tree-planting plans
Albedo can cause large reductions to the climate benefit of tree planting – but new science helps identify locations with greatest climate-cooling potential

Nature research paper: Widespread slow growth of acquisitive tree species

https://go.nature.com/43Tc3GY
Widespread slow growth of acquisitive tree species - Nature
Under field conditions, acquisitive tree species generally grow slowly, whereas conservative species show generally higher realized growth, owing to their ability to tolerate unfavourable environmental conditions.

Happy to share our last study on #forest résistance to #pest insects.
We show that mixed forests are equally résistant to both native and invasive pests, whatever their feeding habits. Preprint available 👇🏻 www.authorea.com/users/948030...
More diverse temperate forests are more resistant against non-native insect herbivores
In general, trees suffer less damage by insect herbivores when growing in forest mixtures than in tree monocultures. Yet, most current knowledge is based on responses of native herbivores to tree dive...

There are myriad examples of prey naivete, enemy release, biotic resistance, mutualisms etc, that demonstrate the importance of evolutionary context in species interactions.

This is why species origins matter. #bioinvasions

The President's Budget request as released yesterday will gut scientific research. Why should you care?
1) Science is fundamentally a jobs program. Many 100,000s are employed to do science and work for you, the US taxpayer.
NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.
