Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Species convergence into life-forms in a hyperseasonal cerrado in central Brazil

Brazilian Journal of Biology
Whether the functional structure of ecological communities is deterministic or historically contingent is still quite controversial. However, recent experimental tests did not find effects of species composition variation on trait convergence and ...

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

Short-term community dynamics in seasonal and hyperseasonal cerrados

Brazilian Journal of Biology
In South America, the largest seasonal savanna region is the Brazilian cerrado. Our aim was to study temporal changes in some community descriptors, such as floristic composition, richness, species density, plant density, and cylindrical volume, in a ...

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Selection of efficient rhizobial symbionts for Cratylia argentea in the cerrado biome

Ciência Rural, 2016
: Cratylia argentea is a leguminous shrub native to the cerrado, which has great potential for forage production and recovery of degraded areas.

Low flammability plants of the cerrado for green fire break

Biodiversidade Brasileira, 2020
Low flammability plants in green fires break can protect against forest fires as they make it difficult to spread fire. Green firebreaks should be strategically implemented in plans for the recovery of fire degraded areas, stoped the flame and services a refuge. Compared to black and traditional firebreaks, green barriers can reduce erosion, vegetation

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, EarlyView.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

Host plants of insect-induced galls in areas of cerrado in the state of Goiás, Brazil

Acta Botânica Brasílica, 2013
Most studies of the interactions between plants and gall-inducing (galling) insects have focused on the entomological aspects, few having addressed the diversity of galls in relation to the characteristics of the host plants.

THE CERRADO LIVE: medicinal plants potentialities

, 2013
Resumo O domínio do Cerrado é pressionado pelas várias atividades econômicas. Divide espaço principalmente com a pecuária, soja, milho e a cana-de-açúcar, comprometendo sua fauna, flora e a Cultura do Povo Cerradeiro. Paradoxalmente é um dos biomas mais ricos em biodiversidade e, quando se incentiva/apoia práticas atentas para essa singularidade, há ...
