Accuracy of occurrence and abundance estimates from insect metabarcoding

Methods in Ecology and Evolution, EarlyView.
Abstract DNA metabarcoding—high‐throughput sequencing of barcode regions from bulk samples—has become a key tool for insect biodiversity assessment. Yet, how methodological choices affect the accuracy of metabarcoding data remains insufficiently explored. In this paper, we ask: (1) How does the lysis method (non‐destructive lysis vs.

Coinvasional disruptions to island pollinator networks

Conservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

A First Indication That Rainforest Vine Proliferation Does Not Enhance Predator–Prey Interactions on the Forest Floor

Entomologia Experimentalis et Applicata, EarlyView.
Vine proliferation is a widespread consequence of tropical forest disturbance, yet its effects on ground‐level predator–prey interactions remain poorly understood. Using plasticine caterpillars deployed on the rainforest floor in north Queensland, Australia, we show that overall predation rates were unaffected by vine‐to‐tree ratio. Instead, fine‐scale

Dietary flexibility and high arthropod availability prevent food limitation in a mountain population of breeding Northern Wheatears

Ibis, EarlyView.
Mountain ecosystems are under strong environmental pressure and are considered highly vulnerable to climate change, which is likely to lead to forest expansion and loss of open alpine grasslands, threatening many specialized species. However, for most alpine birds, even basic ecological knowledge, such as their diet, remains limited, restricting our ...

Changes in the numbers of chromosomes and sex determination system in bushcrickets of the genus Odontura (Orthoptera: Tettigoniidae: Phaneropterinae)

European Journal of Entomology, 2011
Chromosomes of the males of five species of Odontura, belonging to the subgenera Odontura and Odonturella, were analyzed. Intensive evolution of the karyotype was recorded, both in terms of changes in the numbers of chromosomes (from 2n = 31 to 27) and ...

The influence of cutting height on arthropods in farm grassland

Insect Conservation and Diversity, EarlyView.
Mowing at a cutting height of 13 cm slightly reduced the immediate negative impact of mowing compared to mowing at a height of 7 cm. Medium‐term effects overrode this benefit: the number of vegetation‐dwelling arthropods remained strongly reduced two and four weeks after mowing, regardless of the cutting height.

Variations in the ultrastructure of the flight muscles of the polymorphic cricket, Gryllus firmus (Orthoptera: Gryllidae)

European Journal of Entomology, 2012
Although there is a considerable amount of information on the ecology, genetics and physiology of life-history traits there is little information on the morphological variations associated with flight ability within species. In this paper, the morphology
