Simulating climate change scenarios established by the Intergovernmental Panel on Climate Change in aquatic mesocosms

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Climate change poses a major threat to ecosystems worldwide, with temperature changes being a key driver of ecological disruption in aquatic environments due to the limited ability of many aquatic species to relocate in response. Despite advances in aquatic experimental approaches to temperature control, most studies rely on simplified warming

A new species from an inselberg in the Brazilian Atlantic forest: Stachytarpheta forzzae (Verbenaceae), supported by morphological, palynological and anatomical evidence

open access: yesNordic Journal of Botany, EarlyView.
We describe Stachytarpheta forzzae, a new species from an inselberg located in the municipality of Guaratinga, state of Bahia, within the Brazilian Atlantic forest. Morphologically, it resembles S. sprucei, the only other species of the genus known to inhabit inselbergs.

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

open access: yesOikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.
