Climate change prompts monitoring and systematic utilization of honey bee diversity in Turkey
Published: 2020-07-28
Subjects: Agriculture, Apiculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Genetics and Genomics, Life Sciences
Quantitative studies concerning the impact of climate change on pollinators are generally lacking. Relationship between honey bee diversity, present local adaptations and adaptive capacity of subspecies and ecotypes in the face of climate change is an urgent but rather poorly studied topic worldwide. Actually, such an effort lies at the crossroads of various fields of inquiry. Those include [...]
Shade-tree rehabilitation in vanilla agroforests is yield neutral and may translate into landscape-scale canopy cover gains
Published: 2020-06-18
Subjects: Agriculture, Biodiversity, Forest Sciences, Life Sciences
Agroforestry can contribute to an increase in tree cover in historically forested tropical landscapes with associated gains in biodiversity and ecosystem functioning, but only if established on open land instead of underneath a forest canopy. However, declines in yields with increasing shade are common across agroforestry crops, driving shade-tree removal in forest-derived agroforests and [...]

Wind direction, often used in forecasting locust migration, indicates a non-zero probability of desert locust invasion in eastern Indian states. Apart from present controlling measures, we are additionally suggesting to be cautious about the eggs of locust as the rainfall associated with Super Cyclone Amphan has created a favorable breeding ground for the gregarious locust. Also reverse migration [...]
Small-scale farming in drylands: New models for resilient practices of millet and sorghum cultivation
Published: 2020-05-11
Subjects: Agriculture, Life Sciences, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Finger millet, pearl millet and sorghum are amongst the most important drought-tolerant crops worldwide. They constitute primary staple crops in drylands, where their production is known to date back over 5000 years ago. Compared to other crops, millets and sorghum have received less attention until very recently, and their production has been progressively reduced in the last 50 years. Here, we [...]
Honey Bee Diversity Is Swayed by Migratory Beekeeping and Trade Despite Conservation Practices: Genetic Evidences for the Impact of Anthropogenic Factors on Population Structure
Published: 2019-10-13
Subjects: Agriculture, Animal Sciences, Apiculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Genetics, Genetics and Genomics, Life Sciences, Zoology
The intense admixture of honey bee (Apis mellifera L.) populations at a global scale is mostly attributed to the widespread migratory beekeeping practices and replacement of queens and colonies with non-native races or hybrids of different subspecies. These practices are also common in Anatolia and Thrace, but their influence on the genetic make-up of the five native subspecies of honey bees has [...]
Experimenting with the past to improve environmental monitoring programs

Long-term monitoring programs are a fundamental part of both understanding system dynamics and informing management decisions. However, monitoring programs not always designed to consider statistical power, site selection, or the full costs and benefits of monitoring. Further, data from monitoring programs with different goals and protocols are now being combined for comparative analyses. Key [...]
