Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Extreme events induced by climate change alter nectar offer to pollinators in cross pollination-dependent crops

Scientific Reports
Both severe reductions and increases in rainfall can stress plants and modify floral traits involved in plant-pollinator interactions, such as nectar production.

Flower color variation in Digitalis purpurea: Pollination and soil influences across native and introduced populations. [PDF]

Am J Bot
Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

Hotspots on cold mountains: Hot flowers as pollinator refuges in mountain ecosystems

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mountain environments constrain the activity of ectothermic insects. Yet, fine‐scale thermal refuges can buffer these thermal constraints, helping insects remain active in cold conditions.

Dwelling in a post‐fallout landscape: re‐shaping and sustaining life in a former evacuation zone in Fukushima Habiter après la catastrophe : redonner forme au monde et entretenir la vie dans une ancienne zone évacuée à Fukushima

Journal of the Royal Anthropological Institute, EarlyView.
This article explores the activities of daily life in a village neighbouring the TEPCO nuclear power plant in Fukushima. It argues that one of the potentials of taking a dwelling perspective – a phenomenological approach to living within the ecological and social environments – emerges most compellingly within a polluted landscape.

Insights on the nutritional ecology of a nocturnal pollinating insect

Insect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Using honey in wound care [PDF]

, 2006
Honey is primarily a herbal product with some modifications that are made by the bees that process the nectar or sap collected from the plants to store as honey. The types of phytochemicals present in a honey depend on the plant source of the honey.
