Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

open access: yesIbis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

Compatibility and ectomycorrhiza formation among Pisolithus Isolates and Eucalyptus spp Compatibilidade e formação de Ectomicorrizas entre Isolados de Pisolithus e Eucalyptus spp

open access: yesRevista Brasileira de Ciência do Solo, 2005
Twenty-nine isolates of the ectomycorrhiza fungus Pisolithus sp. from different geographical and host origins were tested for their ability to form ectomycorrhizae on Eucalyptus grandis and E. urophylla seedlings under greenhouse conditions.

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

open access: yesInsect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

open access: yesInsect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

open access: yesInsect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

Microcrystalline cellulose: an alternative to increase the resistance of kraft packaging with recycled fiber

open access: yesRevista Brasileira de Ciências Ambientais
O consumo de embalagens de papel está aumentando; em contrapartida, as áreas plantadas de Pinus spp. apresentam tendência de desiquilíbrio entre oferta e demanda. Por isso, muitas empresas estão priorizando a utilização de fibra reciclada; contudo, a sua

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

open access: yesNew Phytologist, EarlyView.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...
