Deep mtDNA divergences indicate cryptic species in a fig-pollinating wasp [PDF]

open access: yes, 2006
Background: Figs and fig-pollinating wasps are obligate mutualists that have coevolved for ca 90 million years. They have radiated together, but do not show strict cospeciation.

Beeswax: Food and beyond

open access: yesFood Biomacromolecules, EarlyView.
Abstract Honeybees (Apis mellifera L.) are an important class of insects that are the most beneficial in terms of economy. Beeswax is the second most important bee products after honey. Its commercial importance is due to its antimicrobial, antioxidant, anti‐inflammatory and antiseptic as well as regenerative properties.

Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

open access: yesGlobal Change Biology Communications, EarlyView.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

open access: yesGrassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.
