Weeds in a changing climate: Competitors or service plants?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

Rootstock-mediated variation in tomato vegetative growth under low potassium or phosphorous supplies

open access: yes, 2015
Grafting provides a rapid and direct tool to transfer rootstock-mediated abiotic stress tolerance to commercial stress-sensitive cultivars. Nutrient deficiency is a widespread problem in some soils, inhibiting physiological processes and thus reducing ...

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

open access: yesPest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

Influence of arbuscular mycorrhizal fungi on the vegetative development of citrus rootstocks

open access: yesPesquisa Agropecuária Tropical, 2016
The use of arbuscular mycorrhizal fungi (AMF) in the production of rootstocks is an alternative to accelerate plant growth. However, their response depends on the symbionts species and environment. This study aimed at evaluating the influence of AMF species [Scutelospora heterogama, Gigaspora margarita, Glomus etunicatum, Acaulospora sp. and a control (

Herbivore species asynchrony underpins multitrophic stability across plants, herbivores and predators

open access: yesJournal of Animal Ecology, EarlyView.
Across a grassland food web, multitrophic stability was most closely associated with herbivore species asynchrony. By identifying herbivores as a key source of temporal buffering between plants and predators, this study shows that intermediate consumers can play a central role in stabilizing the complex food web.
