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).

Migration efficiency sustains connectivity across agroecological networks supporting sandhill crane migration

open access: yesEcosphere, 2021
Preserving avian flyway connectivity has long been challenged by our capacity to meaningfully quantify continental habitat dynamics and bird movements at temporal and spatial scales underlying long‐distance migrations.

Potential Suitable Habitat Distribution and Conservation Strategy for the Siberian Crane (Grus leucogeranus) at Spring Stopover Sites in Northeastern China

open access: yes, 2020
The wetlands where the migratory waterfowl stop during their migration, also called stopover wetlands, are important nodes where migratory waterfowl supplement their energy and food.

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.

Outsourcing Domestic Work in the Crisis of Social Reproduction: Platform‐Mediated Cleaning and the Role of Clients

open access: yesNew Technology, Work and Employment, EarlyView.
ABSTRACT Amid the crisis of social reproduction, outsourcing domestic work has become increasingly appealing, with labour platforms offering new avenues to do so. This article explores the largely overlooked perspective of clients using platform‐mediated cleaning services, focusing on Helpling in Germany.

Determining the Importance of Stopover Destination Attributes: Integrating Stated Importance, Choice Experiment, and Eye-Tracking Measures

open access: yesJournal of Hospitality & Tourism Research, 2020
Stopover tourism is an important but neglected area of study. This article combines a discrete choice experiment with eye-tracking measures and self-stated attribute importance ratings to analyze stopover destination preferences.

The Destination Experience Through Stopover Tourism – Bucharest Case Study

open access: yeswww.amfiteatrueconomic.ro, 2018
Over the years, the evolution of the air transport sector has determined important changes in the tourism industry. One of the consequences of the liberalization of air transport has been the development of the “hub-and-spoke” system, used by traditional airlines in order to be more efficient in a highly competitive environment.

Shorebird responses to fine‐scale water level fluctuations and macrofauna biomass in a newly constructed freshwater wetland

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Restoration of marine and freshwater wetlands for shorebirds is essential for the recovery of their declining populations. An ongoing approach is to restore shorebird habitats by large‐scale engineering, expecting the return of birds once suitable abiotic conditions are (re)established.

At-sea abundance and distribution of skuas and jaegers (Charadriiformes: Stercorariidae) at coastal waters off central Chile [PDF]

open access: yes, 2014
Indexación: Web of Science; Scielo.BACKGROUND: Skuas and jaegers (Charadriiformes: Stercorariidae) are seabirds breeding at moderate to high latitudes and some perform extensive post-breeding transequatorial migrations.
