Passive Acoustic Identification of Social Groups in the Hainan Gibbon

Remote Sensing in Ecology and Conservation, EarlyView.
Passive acoustic monitoring offers a non‐invasive means of assessing visually hard‐to‐survey wildlife species with distinctive vocalizations. We evaluated whether deep learning can identify Hainan gibbon (Nomascus hainanus) social groups from their calls.

Whale-watching and Herring Fishing: Joint or Independent Production? [PDF]

The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for ...

The Application of Autonomous Fixed‐Wing Drones in the Sub‐Antarctic Operating Beyond Visual Line of Sight to Enable Large Area, Multi‐Species Population Monitoring in a Changing Environment

Remote Sensing in Ecology and Conservation, EarlyView.
Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

The Negative Impacts of Whale-Watching [PDF]

Journal of Marine Biology, 2012
Whale watching is an international industry worth more than US$2 billion globally and is currently the greatest economic activity reliant upon cetaceans. However, there is concern that whale watching is detrimental to the target species. Numerous studies have shown that cetaceans exhibit behavioral changes in response to whale-watching boat traffic ...

Evaluation of crowding and tourist satisfaction in the practice of humpback whale - watching, the case of Puerto López - Ecuador

Management Letters/Cuadernos de Gestión, 2019
The effect of crowding on tourist satisfaction is a widely studied aspect. Its knowledge is valuable not only to guide ordering of tourism activity but also to ensure a satisfactory experience that contributes to its economic sustainability.

Few Annotations, High Accuracy: Transfer Learning and Data Augmentation Improve Passive Acoustic Monitoring of the Vulnerable African Manatee

Remote Sensing in Ecology and Conservation, EarlyView.
Can deep learning reliably detect a threatened species in passive acoustic monitoring with few annotations? Across 52 sites and 600 recording days, we compared two deep learning recognizers with the traditional machine learning Kaleidoscope for detecting African manatee vocalizations.

A Systematic Review of Degrowth Food‐Systems, Framework Conceptualisation and Thematic Tensions

Sustainable Development, EarlyView.
ABSTRACT Degrowth food‐systems offer ways to address inequity, poor health, greenhouse gas emissions and biodiversity loss arising from globally dominant industrial food‐systems. In this study, a systematic review of degrowth food‐system research literature was conducted in the Web of Science on 7 February 2025 to identify descriptions of degrowth food‐

From Tourism Intermediary Leverage to Sustainable Development Outcomes: A Systematic Review of Tour Operators, Travel Agencies and Platforms

Sustainable Development, EarlyView.
ABSTRACT Tourism intermediaries are expected to contribute to sustainable development, yet research often stops at policies, intentions or reported practices. This review examines how far studies trace intermediary influence from organisational leverage and action to adoption by another actor and to sustainable outcomes.
