Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...

From low to high elevations, flowers adapt traits and phenology to climate, but phenology‐trait relationships weak

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowering phenology is central to plant reproductive success and can relate to morphological traits such as size and quality of flowers, but phenology–trait associations of flowers remain unclear.

Community‐level effects of Müllerian mimicry on pollinator diversity and functioning

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Are crop yields limited by pollinators? Proper assessments using pollinator gradients require measurements of flower density and yield potential

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract It is widely documented that many crops depend on animal—and primarily insect—pollination, but the degree to which pollinators limit yield in comparison with other factors is poorly understood.

Requerimentos de polinização e biologia floral da castanheira-do-brasil (Bertholletia excelsa Bonpl., Lecythidaceae) em um SAF em Tomé-Açu, Pará. [PDF]

open access: yes, 2011
A castanheira-do-brasil (Bertholletia excelsa Bonpl.) pertence à família Lecythidaceae predominantemente alógama. Estudos prévios mostram que os polinizadores são abelhas da família Apidae (Bombus, Xylocopa, Eulaema, Epicharis, Centris).

Dwelling in a post‐fallout landscape: re‐shaping and sustaining life in a former evacuation zone in Fukushima Habiter après la catastrophe : redonner forme au monde et entretenir la vie dans une ancienne zone évacuée à Fukushima

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article explores the activities of daily life in a village neighbouring the TEPCO nuclear power plant in Fukushima. It argues that one of the potentials of taking a dwelling perspective – a phenomenological approach to living within the ecological and social environments – emerges most compellingly within a polluted landscape.
