Computational ecoacoustics has seen significant growth in recent decades, facilitated by the reduced costs of digital sound recording devices and data storage. This progress enabled continuous monitoring vocal fauna through Passive Acoustic Monitoring (PAM), a technique used to record analyse environmental sounds study animal behaviours their habitats. While collection ecoacoustic become more accessible, effective analysis this information understand monitor populations remains major challenge. survey paper presents state-of-the-art approaches, with focus on applicability large-scale PAM. We emphasise importance PAM, as it enables extensive geographical coverage monitoring, crucial for comprehensive biodiversity assessment understanding ecological dynamics over wide areas diverse approach is particularly vital face rapid changes, provides insights into effects these changes broad array species ecosystems. As such, we outline most challenging tasks, including pre-processing, visualisation, labelling, detection, classification. Each evaluated according its strengths, weaknesses overall suitability recommendations are made future research directions.

While sustainability is widely recognized as necessary for managing heritage sites, balancing preservation demands with tourism development pressures presents significant challenges. A critical gap in the existing research relates to understanding recurring issues that undermine long-term of prominent archaeological destinations Egypt and visitor well-being. Specifically, more needed identify specific experience problems persist across Egypt’s major sites despite ongoing management efforts. Addressing this knowledge could help inform strategies these balance conservation priorities a sustainable manner enhances visitors’ cultural exploration. This study contributes novel multisite content analysis over 4423 online reviews from TripAdvisor pertaining three premier destinations—Giza Pyramids, Al Mu’izz Street, Saqqara. Using established text mining methodologies algorithms within Voyant Tools, challenges were identified through word frequency, concept network, trend analyses. Recurring documented included uncontrolled commercialization undermining ambiance historic locales, environmental degradation inadequate waste overflows, overcrowding compromising comfort, health safety. Deficiencies signage, transportation, other tourist services also themes. The holistic evaluation cross-cutting concerns faced at diverse yet interrelated advanced theoretical on cooperative governance models competencies integrative management. recommendations center collaborative stakeholder partnerships reform commercial practices licensing enforcement, upgrading aging infrastructure support volumes, implementing zoning carrying capacity policies tailored local community contexts. proposed solutions aim safeguard irreplaceable treasures by addressing recurrent environmental, economic socio-cultural if left unresolved, positioning its wonders appreciation present future generations.

Tourist activities in forest areas can potentially disturb wildlife, including bird species. One of the responses to such disturbances is avoidance. This study aimed investigate and analyze tolerance levels various species recreational Gunung Gede Pangrango National Park, West Java, Indonesia. The method used this research involved “dummy tourist activities” that varied by distance tourists walked birds, number tourists, noise made tourists. results showed birds had a maximum for around 10 m, while attractive 20 m. closest observe all was 5 It concluded avoidance human or disturbances. Raptors colorful low responses; songbirds medium tolerance, high tolerance. Information on response dynamics useful creating tourism site planning landscape design based ecological wildlife carrying capacity. Keywords: response, birdwatching, disturbance ecotourism, Park
