Introduction
My main interests are biodiversity and species identification, with a particular reference to the use of DNA barcoding and eDNA metabarcoding to identify a wide panel of organisms (animals, plants, bacteria), their occurrence in environmental matrices (soil, water, faeces, and food) and their interactions (diet, pollen loads).

Article
Individual and species traits may determine the functional relationships between predators and their prey, with clear consequences for the ecosystem services potentially associated with predation. Bats are well-known potential deliverers of ecosystem services in agroecosystems through predation of pest arthropods that may affect crop production. He...

Flowers have many sensory traits to appeal to pollinators, including ultraviolet (UV) absorbing markings, which are well known for attracting bees at close proximity (e.g. < 1 m). While striking UV signals have been thought to attract pollinators also at greater distances of meters, how the signals impact the plant pollination success over distance...

Maldives islands host a unique biodiversity, but their integrity is threatened by climate change and impacting land-uses (e.g. cemented or agricultural areas). As pollinators provide key services for the ecosystems and for the inhabitants, it is crucial to know which pollinators occur in the islands, to characterise their genetic identity and to un...

Habitat fragmentation affects biodiversity, but with unclear effects on pollinators and their interactions with plants in anthropized landscapes. Islands could serve as open air laboratories, suitable to disentangle how land-use alteration impacts pollination ecology. In Maldive islands we investigated how pollinator richness, plant-pollinator inte...

Plant mating systems may reflect an adaptation to a habitat type, with self-pollination being potentially common in unstable and disturbed conditions. We investigated the reproductive ecology of an Alpine, narrow-range toadflax, Linaria tonzigii Lona (Plantaginaceae), occurring in steep and dynamic mountain screes. We explored self-compatibility an...

The genus Crocidura (Eulipotyphla, Soricidae) is the most speciose genus amongst mammals, i.e., it includes the highest number of species. Different species are distinguished by skull morphology, which often prevents the identification of individuals in the field and limits research on these species' ecology and biology. We combined species distrib...

The Odonata are considered among the most endangered freshwater faunal taxa. Their DNA‐based monitoring relies on validated reference datasets that are often lacking or do not cover important biogeographical centres of diversification.

Female promiscuity can function to acquire both direct and indirect benefits from their social mate and extra‐pair males. In many raptor species, intense mate‐feeding significantly contributes to female energy requirements before and during egg laying. Moreover, females may use mate‐feeding effort to assess male quality. In this study of the lesser...

Floral deception has been observed in several genera in angiosperms, but is most common in the Orchidaceae. Pollination mechanisms in food deceptive plants are often difficult to assess, as visitation frequency by insects requires numerous hours of field observations to ascertain.
