Against the central-marginal model: Three cases in chromosomally polymorphic grasshoppers (Orthoptera: Acrididae)

open access: yesEuropean Journal of Entomology, 2012
The central-marginal model is widely accepted in chromosomally polymorphic species of Drosophila. In fact, geographically and ecologically central populations of Drosophila show higher levels of polymorphism for paracentric inversions, whereas marginal ...

Food Availability Cannot Explain Dispersal and Settlement Decisions of a Grassland Bird

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We test a commonly assumed explanation for animal movements—namely that food availability shapes where animals disperse to. Based on the results of four strong predictions, 3 years of data, and hundreds of individual birds, we show that food cannot explain breeding dispersal in this system, and we propose alternative explanations consistent with our ...

Population structures of three Calliptamus spp. (Orthoptera: Acrididae) across the Western Mediterranean Basin

open access: yesEuropean Journal of Entomology, 2012
We conducted a comparative population genetic analysis of levels of genetic variation and its geographical structuring in three closely related species of grasshopper that co-occur in the Mediterranean Basin: Calliptamus italicus, C.

Accuracy of occurrence and abundance estimates from insect metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 8, Page 2343-2363, August 2026.
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.

The central-marginal hypothesis in acridid Orthoptera: A critique of Colombo's (2012) article

open access: yesEuropean Journal of Entomology, 2013
We discuss and criticise the contention of Colombo (2012) that the central-marginal model does not apply to three species of chromosomally polymorphic acridid grasshoppers, and that chromosomal clines in these species are a consequence of temperature ...

Optimisation of Drop‐Sheet Sampling in Macadamia (Macadamia integrifolia) Orchards: An Optimised Method for Monitoring Insect Ecology

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Understanding orchard arthropod populations is a critical element of making strategic decisions regarding pest management. Therefore, it is paramount for farmers and crop consultants to use appropriate survey methods that provide a representative sample of orchard insect ecology. Currently, macadamia (Macadamia integrifolia) industry arthropod
