Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity
ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...

Molecular Interactions of Pyridine With Water: A Combined DFT Benchmarking and QTAIM Analysis
Microsolvation of pyridine by up to ten water molecules was explored using benchmarked DFT and QTAIM analyses, revealing a transition from a single OH…N hydrogen bond to cooperative three‐dimensional hydrogen‐bond networks. Increasing hydration promotes cage‐like water structures and diverse non‐covalent interactions, governing conformational stability

Ecology and evolution of pyrazines in insects
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Foraging ecology and conservation of honeybees, bumble bees and solitary bees
This thesis contributes to two inter-related fields of research: bee conservation and bee foraging ecology. The first focuses on solitary bee ecology, identifying forage and habitat requirements along with educating the general public on aspects of solitary bee behaviour to aid in the conservation of the studied species.

This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Age‐related downregulation of AcSirt2 impairs mitochondrial homeostasis in old bees. AcSirt2‐mediated deacetylation of FOXO enhances transcriptional activity, upregulating antioxidant enzymes (SOD, CAT) and promoting PINK1/Parkin‐mediated mitophagy. This pathway facilitates autophagosome formation and clearance of damaged mitochondria, reducing ROS ...

Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.
