Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Ideias leguminosas

open access: yes, 2016
A comunicação de Ciência nas escolas de 1o Ciclo limita-se, muitas vezes, à abordagem superficial dos conteúdos previstos nas metas curriculares da área de Estudo do Meio, sem recurso a actividades experimentais, laboratoriais ou de campo. A Escola Sementes de Liberdade é uma escola particular do 1o Ciclo que promove a abordagem de Ciência em contexto ...

Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

open access: yesInsect Conservation and Diversity, EarlyView.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Soil sand content is a driving force in structuring bee communities

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted a carefully designed observational study across three soil sand content categories using Dalea purpurea that attracts a wide range of bee species and grows in different soil types. Soil sand content, not floral resource availability, affected patterns of bee distribution, and contrary to expectations, sandier sites did not host the highest

Phytotoxic potential of Senna occidentalis and Senna obtusifolia = Potencial fitotóxico de Senna occidentalis e Senna obtusifolia

open access: yesActa Scientiarum: Biological Sciences, 2010
This work aimed to investigate the phytotoxic potential of the aerial and underground parts of Senna occidentalis and S. obtusifolia on the germination and initial growth of lettuce and onion. Four concentrations were used of each ethanol extract (0, 250,

Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Structural variation drives rhizome innovation and adaptive divergence in sister Medicago species

open access: yesJournal of Integrative Plant Biology, EarlyView.
Chromosome‐scale genome analysis, population resequencing, stress‐responsive transcriptomes and functional assays showed that coding and regulatory structural variants, especially gene duplications and noncoding presence‐absence variants, underlie rhizome formation in alpine Medicago archiducis‐nicolai and contrasting xeric adaptation in its non ...
