Flight of the dragons: a global review of migration in Odonata
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Curating landscapes to encourage care for biodiversity through arts and citizen science
Abstract This study investigates how combining Citizen Science and Art workshops within curated wildflower meadows can generate repeated, positive experiences with nature, and foster a sense of care for it. The project aimed to increase awareness, encourage responsibility, and develop competencies related to urban nature.

In a large‐scale German forest experiment, habitat heterogeneity increased spider turnover but reduced local alpha diversity through habitat filtering. Together, these effects lowered landscape‐scale spider diversity. As such, the study shows whether environmental heterogeneity increases or decreases biodiversity depends on the balance between habitat ...

An experimental manipulation of ray florets in Knautia arvensis (Caprifoliaceae) carried out in 2001 originally yielded results that were hard to reconcile with a hypothesis about floral attraction.

Comparing ecological and economic benefits of organic farming and annual flower strips
Integrating agri‐environment schemes such as organic farming and wildflower strips offers complementary effects on biodiversity conservation. Implementing these schemes enhanced biodiversity by 20%–30%, while maintaining economic viability and similar profits/ha through premium pricing and subsidies.

ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral

Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.

Mimcry and the hoverflies [PDF]
Hoverflies (Diptera: Syrphidae) vary widely in their mimetic associations, comprising wasp-mimetic, bee-mimetic and non-mimetic species. Social wasp mimics are dominated by 'imperfect mimics' which outnumber their supposed models (Hymenoptera: Vespidae ...
