BACKGROUND AND AIMS Studies of local floral adaptation in response to geographically divergent pollinators are essential for understanding floral evolution. This study investigated local pollinator adaptation and variation in floral traits in the rewarding orchid Gymnadenia odoratissima, which spans a large altitudinal gradient and thus may depend on different pollinator guilds along this gradi...

Improved agroecological practices tend to lead production diversity but often fall short of achieving optimal dietary in rural contexts. Thus, multi-prong interventions involving knowledge and skill development for consumption are needed. This study assesses nutrition production-related implemented the East African Highlands, Pamir-Tian Shan, Hindukush Andes. Overall, 601 service providers were...

Remote sensing information is critical to preserve environments in tropical and mountain regions (e.g., costal hurricane mitigation or mountain forest management). In order to partition graphical information into meaningful regions and extract salient objects, segmentation is used to identify visual signatures based on similarity criteria. Due to atmospheric dispersing, nonlinear denoising is n...
