Eriope carpotricha (Lamiaceae, Hyptidinae), a new critically endangered species from the Espinhaço Range of Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Eriope (Lamiaceae) is a Neotropical genus primarily found in Brazil's Campos Rupestres and extending to other South American regions. It was confirmed as monophyletic in recent molecular studies and includes over 30 species. Originally described with 13 species, the genus expanded through further classifications and revisions. Recent fieldwork in Monte

A notable new narrow‐endemic species of Jurinea (Asteraceae) from the subalpine region of western Iran

Nordic Journal of Botany, EarlyView.
Extensive field studies in remote areas of Chaharmahal and Bakhtiari Province, Iran, resulted in the identification of a novel Jurinea species (Asteraceae: subtribe Saussureinae). Jurinea kuhrangensis sp. nov., a chasmophytic species endemic to limestone outcrops in the subalpine region of Kuhrang County, is formally documented in this study ...

Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

Oikos, EarlyView.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Conserving wildlife through demand reduction and supply alternatives: Two experiments in restaurants in Kinshasa

People and Nature, EarlyView.
Abstract High aggregate levels of wildlife consumption in cities in Central Africa highlight the need for solutions that balance wildlife protection, local livelihoods and the relational values between people and nature. This study explores the impacts of demand‐ and supply‐side interventions on wild meat consumption through two randomized control ...
