Modelling the national breeding distribution and population size of an elusive forest bird, the Eurasian Woodcock (Scolopax rusticola)

open access: yesIbis, EarlyView.
Understanding the distribution of species is central to conservation biology. Species distribution modelling (SDM) is a standard method used for this purpose, especially for elusive species for which limited occurrence data exist. The Eurasian Woodcock Scolopax rusticola (hereafter Woodcock) is an elusive, woodland‐dwelling wader that is declining in ...

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

open access: yesIbis, EarlyView.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Linking eBird data with high spatiotemporal remote sensing products to estimate occupancy of bird populations across the island of Ireland

open access: yesIbis, EarlyView.
The vast increase in biodiversity data generated through citizen science initiatives, alongside a growing suite of remote sensing products and advanced modelling tools, has opened new avenues for rapidly, accurately and efficiently monitoring species trends to inform conservation, management and policy.

Shelters or ecological traps? Context‐dependent effects of nestboxes on breeding success in a colonial raptor

open access: yesIbis, EarlyView.
Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

open access: yesIbis, EarlyView.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Prehistoric shuttle dispersals in a Malthusian economy

open access: yesInternational Journal of Economic Theory, EarlyView.
Abstract Early humans undertook multiple waves of migration out of Africa and back to the continent. We explore prehistoric human migration in a two‐region Malthusian growth model. Whether migration occurs depends on the migration cost, relative population size, relative land supply, and relative hunting‐gathering productivity between regions.
