In Europe, the quality of coastal bathing waters improved considerably in the last decades, mainly due to the more demanding legislation and the adoption of water sanitation plans. In the Nerbioi estuary (North Spain), the Wastewater Treatment Plan implemented between 1990 and 2001 resulted on an abrupt decrease in microbial concentration; thus, complying with bathing waters legislation and allowing recreational activities again in the three beaches of the estuary. However, little is known about how improvements in bathing waters influences the provision of cultural ecosystem services and human well-being. A questionnaire was used to study beach users' behaviour and perceptions and compared with environmental time-series data (microbial concentration and water transparency). Most respondents perceived an improvement in bathing waters quality and linked it to the estuarine sanitation. Nerbioi beaches are important recreational areas, mainly for local visitors, and water quality improvement was found to be a critical factor for deciding to visit these beaches. Furthermore, most visitors answered that they would not return if water conditions deteriorate. Significant differences existed between beaches, with the most inner beach presenting worse environmental conditions than the other two beaches; and matching user's perceptions. Our findings highlight that water sanitation actions are important for the recovery of degraded coastal environments and for the maintenance of ecosystem services. Also, that multidisciplinary research is necessary to better comprehend the links between environmental recovery and the provision of ecosystem services.

Invertebrates form a vital component of agricultural ecosystems, and they are chief actors in sustaining the functions of the ecosystem and soil health. Scholarly publications that concentrated on visualizing the research outputs and trends on invertebrates and agriculture are scarce. In this paper, we adopted a bibliometric model to extract trends/research studies on invertebrates and agriculture between 1991 and 2022, using scholarly studies retrieved from the Web of Science (WoS) databank.

We briefly review the history and development of recognizing nematode assemblages as indicators of environmental conditions. We highlight the effects of spatio-temporal successional changes in nematode assemblages on the auto-regeneration of ecosystem functions after disturbance. We expand on the need for herbivory components in the analysis of soil nematode assemblages in recognition of the important impact of plant parasitism on the resources and productivity of the soil system.

Stingless bees (tribe Meliponini), comprising over 600 known species within the largest group of eusocial bees, play a critical role in ecosystem functioning through their pollination services. They contribute to the reproduction of numerous plant species, including many economically important crops such as cacao, coffee, and various fruits. Beyond their ecological significance, stingless bees hold cultural and economic importance for many native and rural communities, where they are managed for their honey, pollen, and propolis for nutritional and health purposes.

Despite widespread attention to interactions between functional traits and community responses to environmental changes, the importance of sensory traits has received little attention. To address this, we asked whether visual traits of bumblebee communities varied at large geographical scales along a habitat gradient of increased tree cover.

Blue carbon ecotones (BCEs) play a critical role in regulating abiotic and biotic ecological fluxes underpinning services which are also crucial for the protection of the land-ocean function. Here, we proposed a Benefit-Pressure-Transformation Risk model (BPT) to calculate the Ecosystem Health Index (EHI) for mangrove, salt marsh, and seagrass as core BCEs globally (at a resolution of 1° × 1 °lat-long), based on habitat structure, species morphological features and vulnerability, niche overlap, nature and human pressures, and ecosystem services. Our assessments identify that around 20% of BCEs as vulnerable globally.
