Regioselective Oxidative Phenol Coupling by a Mushroom Unspecific Peroxygenase

open access: yesAngewandte Chemie International Edition, Volume 63, Issue 42, October 14, 2024.
The phlegmacin biosynthesis in the mushroom Cortinarius odorifer reveals that CoUPO1, an unspecific peroxygenase, catalyzes the dimerization step by regio‐ and stereoselective oxidative phenol coupling. This study demonstrates that mushrooms evolved aryl coupling independently of any other group of organisms.

The orchid-bee fauna (Hymenoptera: Apidae) of ‘Reserva Biológica de Una’, a hotspot in the Atlantic Forest of southern Bahia, eastern Brazil

open access: yesBrazilian Journal of Biology
The orchid-bee fauna of ‘Reserva Biológica de Una’ (REBIO Una), one of the largest Atlantic Forest remnants in southern Bahia, eastern Brazil, was surveyed for the first time. Baits with sixteen different scents were used to attract males of orchid bees.

The specialised buzz pollination syndrome poses a partial barrier to plant invasions

open access: yesJournal of Ecology, Volume 112, Issue 8, Page 1686-1700, August 2024.
We found that plants that exhibit traits consistent with the buzz‐pollination syndrome are underrepresented as invasive species across the globe. Our result suggests that the specialist buzz‐pollination syndrome poses a partial barrier to plant invasions. Our review also highlighted six alternative insect behaviours that can enable invasive plants with

Biomonitoramento de abelhas euglossina (Apidae, Hymenoptera) em um SAF com castanheira-do-brasil (Bertholletia excelsa Bonpl., Lecythidaceae) em Tomé-Açu, Pará. [PDF]

open access: yes, 2011
A castanha-do-brasil (Bertholletia excelsa) é uma planta nativa da Amazônia e uma das mais importantes espécies de exploração extrativista do Brasil. É uma espécie melitófila, polinizada por abelhas de grande porte, como os Euglossina dos gêneros Eulaema

La arquitectura de nidos de Euglossa (Euglossa) hemichlora (Hymenoptera: Apidae: Euglossini)

open access: yesRevista Colombiana de Entomología, 2009
La información sobre la biología de nidificación de las abejas de las orquídeas es escasa debido a la gran dificultad para encontrar sus nidos. Se presentan observaciones y comentarios sobre la arquitectura de los nidos de Euglossa hemichlora obtenidos a partir de nidos trampa a la vez que se presentan datos de la biología de nidificación de esta ...

Temporal variation in the abundance of Orchid Bees (Hymenoptera: Apidae) in a Neotropical Hygrophilous Forest

open access: yesSociobiology, 2014
Although bees are important pollinators in several ecosystems around the world, studies on bee diversity in hygrophilous forests are scarce. This type of vegetation is restricted to permanently wet soils and, therefore, has particular floristic ...

Biomonitoramento de abelhas da subtribo euglossina (Hymenoptera: Apoidea) em um plantio de castanheira-do-brasil (Bertholletia excelsa Bonpl., Lecythidaceae) em Belém, Pará. [PDF]

open access: yes, 2011
Com a finalidade de conhecer a biodiversidade de abelhas da subtribo Euglossina em áreas cultivadas com castanheira-do-brasil (Bertholletia excelsa Bonpl.), foi realizado monitoramento mensal em: um monocultivo de castanheira-do-brasil, e áreas ...

The Draft Genome of the Invasive Walking Stick, Medauroidea extradendata, Reveals Extensive Lineage-Specific Gene Family Expansions of Cell Wall Degrading Enzymes in Phasmatodea. [PDF]

open access: yes, 2018
Plant cell wall components are the most abundant macromolecules on Earth. The study of the breakdown of these molecules is thus a central question in biology.
