A global perspective on the annual cycles of whimbrels

open access: yesIbis, EarlyView.
Comparative analyses are central to understanding broad‐scale patterns in avian ecology, yet their application is often constrained by fragmented and uneven data availability. Recent advances in tracking technology have generated unprecedented insights into shorebird movements, resulting in numerous studies on single populations or flyways.

Forest biomass monitoring with GNSS-R: theoretical simulations

open access: yes, 2011
GNSS-Reflectometry (GNSS-R) is a remote sensing technique which performs bistatic measurements of the earth surface scattering. This paper presents some theoretical simulations of the specular scattering coefficient of a forested area, with the aim of ...

Periodontal Status of Type 1 Diabetes Mellitus and Healthy Pregnant Women: A Case–Control Pilot Study

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Aims This cross‐sectional ‘case–control’ pilot study aimed to compare the size of periodontal wounds, periodontal status and total inflammatory burden between pregnant women with type 1 diabetes mellitus (T1DM) and non‐diabetic pregnant women. Methods Fifteen T1DM pregnant women and 15 healthy pregnant women were included. Clinical parameters (

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Soil moisture retrieval based on LHCP and RHCP GNSS-R signals

open access: yes, 2015
Soil moisture can be retrieved using radar techniques or L-band microwave radiometry. Recently, Global Navigation Satellite System Reflectometry (GNSS-R) techniques have been demonstrated to be useful for many applications as sea-state retrieval and soil

Sensitivity to soil moisture of spaceborne GNSS-R observables

open access: yes, 2018
The potential of GNSS-R techniques to estimate land surface parameters such as Soil Moisture (SM) is experimentally studied using 2014-2017 global data from the UK TechDemoSat-1 (TDS-1) mission. The approach is based on the analysis of the sensitivity to
