`Been there done that': Disentangling option value effects from user heterogeneity when valuing natural resources with a use component. [PDF]

, 2009
Endogeneity bias arises in contingent valuation studies when the error term in the willingness to pay (WTP) equation is correlated with explanatory variables because observable and unobservable characteristics of the respondents affect both their WTP ...

Performance of a glider‐mounted multifrequency echosounder for measuring the vertical distribution and abundance of large pelagic copepods

Limnology and Oceanography: Methods, EarlyView.
Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Changes in cetacean occurrence in Faxaflói Bay, Iceland, as observed from whale watching vessels

NAMMCO Scientific Publications
The distribution of animal species is shaped by environmental conditions and their ecological niches. The understanding of these niches is essential for conservation, especially for cetaceans, as cetacean species may adjust their geographical range in ...

Which Patients With Dysfunctional Voiding Respond Well to Sacral Neuromodulation? ICI‐RS 2025

Neurourology and Urodynamics, EarlyView.
ABSTRACT Aims Dysfunctional voiding (DV) is characterised by fluctuating or intermittent urinary flow during voiding in neurologically normal individuals. Given the different definitions used and heterogeneous pathophysiologies, outcomes following sacral neuromodulation/sacral nerve stimulation (SNM/SNS) are variably reported.

TESTING SIGNIFICANCE OF MULTI-DESTINATION AND MULTI-PURPOSE TRIP EFFECTS IN A TRAVEL COST METHOD DEMAND MODEL FOR WHALE WATCHING TRIPS [PDF]

Inclusion of multi-destination and multi-purpose visitors has an appreciable influence on a standard count data travel cost model derived estimate of willingness to pay but the differences are not statistically significant. We adapt a more general travel

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Developing ocean literacy through a relational model: Exploring outcomes of a place‐based ocean education programme in primary schools

People and Nature, EarlyView.
Abstract Schools are a common place where the younger generation can develop their understanding of the ocean and acquire the skills needed to become responsible and knowledgeable ocean advocates. Grounded in a relational ocean literacy model, this study examined outcomes of a place‐based programme integrating picture books, beach excursions and ...

A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

Journal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.
