The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

Biological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Gap perception in bumblebees [PDF]

Journal of Experimental Biology, 2018
AbstractA number of insects fly over long distances below the natural canopy where the physical environment is highly cluttered consisting of obstacles of varying shape, size and texture. While navigating within such environments animals need to perceive and disambiguate environmental features that might obstruct their flight. The most elemental aspect

Effect of urbanization and its environmental stressors on the intraspecific variation of flight functional traits in two bumblebee species

Oecologia, 2021
The way urbanization shapes the intraspecific variation of pollinator functional traits is little understood. However, this topic is relevant for investigating ecosystem services and pollinator health.

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Ecological Stoichiometry of Bumblebee Castes, Sexes, and Age Groups

Frontiers in Physiology, 2021
Ecological stoichiometry is important for revealing how the composition of chemical elements of organisms is influenced by their physiological functions and ecology.

The use of edible insects in human food

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The world population is expected to reach approximately 10 billion people by 2050, which will significantly increase global food demand and may lead to agricultural shortages and a higher risk of food insecurity. In this context, this review discusses the potential of insects as alternative sources of animal protein, addressing their ...

Identification of fungi isolated from commercial bumblebee colonies [PDF]

PeerJ
Fungi can have important beneficial and detrimental effects on animals, yet our understanding of the diversity and function of most bee-associated fungi is poor.

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

PLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Effectiveness of native bumblebees as pollinators of the alien invasive plant Impatiens glandulifera (Balsaminaceae) in Ireland

Journal of Pollination Ecology, 2009
Flowers of alien invasive plants can be pollen limited due to a lack of effective pollinators. The alien Impatiens glandulifera is predominantly visited by bumblebees in its invaded range. There bumblebees pollinate I.

Bumblebee Flight in Heavy Turbulence [PDF]

Physical Review Letters, 2016
High-resolution numerical simulations of a tethered model bumblebee in forward flight are performed superimposing homogeneous isotropic turbulent fluctuations to the uniform inflow. Despite tremendous variation in turbulence intensity, between 17% and 99% with respect to the mean flow, we do not find significant changes in cycle-averaged aerodynamic ...
