Nanomaterials‐Decorated Biomass‐Derived Carbon for Overall Water Splitting: Interfacial Engineering, Mechanistic Insights, and Device Translation

open access: yesThe Chemical Record, EarlyView.
Biomass‐derived carbon provides a sustainable, porous, and conductive scaffold that stabilizes nanomaterials for bifunctional hydrogen evolution reaction/oxygen evolution reaction catalysis. This review summarizes design strategies (defects, heteroatom doping, heterostructures, single atoms), mechanistic/density functional theory insights, degradation ...

Effects of Gamma Radiation on Salix nigra Marsh Cuttings [PDF]

open access: yes, 1985
Dormant cuttings of Salix nigra Marsh, were exposed to gamma radiation from a cobalt-60 source at a dose rate of 1110 roentgens (r) per minute. Exposure doses ranged from 50 r through 100 Kr with 100% mortality at 10 Kr.

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

open access: yesFunctional 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.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Insights on the nutritional ecology of a nocturnal pollinating insect

open access: yesInsect 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)

open access: yesInsect 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 ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Allergic Sensitization to Inhalant Allergens in the Upper Respiratory Tract—the B Cell Side

open access: yesAllergy, EarlyView.
ABSTRACT Allergic diseases are on the rise worldwide, driven by respiratory epithelial barrier dysfunction that promotes sensitization to inhalant allergens such as pollen, dust mites, pet dander, and fungal spores. These antigens trigger IgE‐mediated immune responses that lead to diseases such as allergic rhinitis (AR) and asthma.

The heat stress effect on pollen development and germination [PDF]

open access: yes, 2009
Povišena temperatura ima značajan učinak na sve biljne organe i sve razvojne faze u životu biljke. Osobito je važan učinak na razvoj peluda i ženskih reproduktivnih organa, klijanje peludne mješinice i uspješnost stvaranja ploda.

Biphasic Effects on Allergen‐Specific Type 2 Memory B Cells Over 18 Months Sublingual Immunotherapy for House Dust Mite Allergy

open access: yesAllergy, EarlyView.
Rapid clinical relief of allergy symptoms during 18 months of sublingual immunotherapy (SLIT) for house dust mite (HDM) is associated with increased serum IgE, IgG2, and IgG4 to Der p 1 and Der p 2. Der p 1 and Der p 2 specific Type 2 memory B cells are expanded at 4 months and 12 months of SLIT, with increased expression of CD29 and IgG4.
