Estimativa do filocrono em milho para híbridos com diferentes ciclos de desenvolvimento vegetativo Estimating the phyllocron in maize hybrids with different cycles of vegetative development

open access: yesCiência Rural, 2012
O filocrono é definido como o tempo térmico necessário para o aparecimento de folhas sucessivas na haste principal de uma planta. Através do filocrono, pode-se calcular a duração do período vegetativo e, portanto, a época de florescimento em função da ...

Niche‐tracking as a collecting method: Habitat‐targeted search strategies for taxon‐focused botany

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity science depends on more than collecting plants—it depends on how we search for them. Although GPS and digital maps have transformed fieldwork, they can also encourage repeated visits to the same easy‐to‐access sites, leaving other habitats and populations unknown to science.

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

open access: yesPest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Methomyl resistance in Dalbulus maidis (Hemiptera: Cicadellidae): selection, inheritance and multiple‐resistance

open access: yesPest Management Science, EarlyView.
The inheritance of methomyl resistance in Dalbulus maidis is autosomal, incompletely dominant and polygenic. No cross‐resistance was found between methomyl and chlorfenapyr, cyantraniliprole and isocycloseram. Abstract BACKGROUND Acetylcholinesterase (AChE) inhibitor insecticides have been important tools for the management of Dalbulus maidis in Brazil;

From Plot to Block: Participatory Land Use for Climate‐Resilient Detached Housing in Finland

open access: yesSustainable Development, EarlyView.
ABSTRACT This study investigates how urban planning in Finland is adapting to climate change, focusing on the practical challenges planners face in single‐family housing areas. It draws on participatory workshops with municipal planners in Pori and Joensuu, where three planning tools—green factor metrics, impermeable surface limits, and the 3–30‐300 ...

Presence of Nationally Banned Carbamates and Organophosphate Pesticides in Wild Carnivores, Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT As top predators, terrestrial carnivores face great risk of pesticide exposure and serve as sentinels of environmental contamination. Additionally, terrestrial carnivores are frequently threatened by intentional or secondary poisoning with highly toxic compounds, such as carbamates and organophosphates.
