An evaluation of pollination methods for strawberries cultivated in plant factories: robot vs hand
The cultivation of strawberries in plant factories with artificial lighting (PFAL) has recently been recognized as it makes pesticide-free and stable year-round production possible.

Pesticide Mediated Critical Transition in Plant-Pollinator Networks [PDF]
Mutually beneficial interactions between plant and pollinators play an essential role in the biodiversity, stability of the ecosystem and crop production. Despite their immense importance, rapid decline events of pollinators are common worldwide in past decades.

Abstract Arthropod biomass is a key element in ecosystem functionality and a basic food item for many species. It must be estimated through traditional costly field sampling, normally at just a few sampling points. Arthropod biomass and plant productivity should be narrowly related because a large majority of arthropods are herbivorous, and others ...

Pollination Efficiency and the Evolution of Specialized Deceptive Pollination Systems [PDF]
The ultimate causes of evolution of highly specialized pollination systems are little understood. We investigated the relationship between specialization and pollination efficiency, defined as the proportion of pollinated flowers relative to those that experienced pollen removal, using orchids with different pollination strategies as a model system ...

Rarity begets rarity: Social and environmental drivers of rare organisms in cities
Abstract Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity.

Cocoa pollination, biodiversity-friendly production, and the global market [PDF]
Production of cocoa, the third largest trade commodity globally has experienced climate related yield stagnation since 2016, forcing farmers to expand production in forested habitats and to shift from nature friendly agroforestry systems to intensive monocultures.

Beyond 3D: Smart Material Systems for Microscale 4D Printing
Smart materials exhibit shape changes in response to their environment, enabling scientists to go beyond 3D in the rapidly growing field of 4D printing. This review covers recent advances, current challenges, and emerging trends in 4D printing on the microscale.

Abstract As fragmented landscapes become increasingly common around the world, managing the spatial arrangement of landscape elements (i.e., landscape configuration) may help to promote the conservation of biodiversity. However, the relative effects of landscape configuration on different dimensions of biodiversity across species assemblages are ...

Testing Pollination Syndromes in Oenothera (Onagraceae)
Pollinators are considered a major selective force in shaping the diversification of angiosperms. It has been hypothesized that convergent evolution of floral form has resulted in “pollination syndromes” - i.e.

Exotic insect pollinators and native pollination systems
Insect pollinators have been relocated by humans for millennia and are, thus, among the world’s earliest intentional exotic introductions. The introduction of managed bees for crop pollination services remains, to this day, a common and growing practice worldwide and the number of different bee species that are used commercially is increasing.
