Sustainable Development, EarlyView.ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Environmental Toxicology, EarlyView.ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

Pollen tube incompatibility reaction on the stigma in selfpollinated Sinapis alba L.
Acta Societatis Botanicorum Poloniae, 2014 After selfpollination of Sinapis alba L. pollen tubes growth is inhibited on the stigma. The pollen grains germinate 3-4 hours after pollination. The pollen give rise to one or more pollen tubes. They grow along the papillae.

Bird extinctions shift bill–flower trait matching in Hawaiian lobelioids
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Species extinctions can reorganize ecological interactions by altering the distribution of functional traits within communities. These traits structure how species interact, influencing whether encounters result in mutualistic or antagonistic outcomes.

Foraging energetics reveals late‐summer challenges for pollinators across two British cities
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

浙江大学学报. 农业与生命科学版, 2012 Lagerstroemia indica was transformed by an improved Agrobacterium-mediated floral-dip and pollen-tube pathway method, respectively, using green fluorescent protein gene (GFP) as a report gene, and its fruit number, rate of seed-setting set and seedling ...

Journal of Animal Ecology, EarlyView.In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success
Insect 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.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone
Insect Science, EarlyView.We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Ants contribute to raspberry pollination in protected cropping systems
Agricultural and Forest Entomology, EarlyView.Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...
