Structure and Functionality of the Mesozooplankton Community in a Coastal Marine Environment: Portofino Marine Protected Area (Liguria)

This research is part of the LTER (Long-Term Ecological Research) project, a network of terrestrial, freshwater, transitional water and marine sites, on which ecological research is conducted on a multi-decade scale. LTER studies ecosystems, their dynamics and evolution, the relationships between biodiversity and ecological functionality, water quality, productivity, the role of resource availability, the effects of pollution and climate change. The research focuses on the study of the variability of zooplankton groups in the Portofino marine protected area, in Punta Faro. The samplings were carried out in the years 2018–2019, and the results were compared with the values of the years 2003–2005, interesting from a meteorological climatic and biological point of view. The plankton community of the Punta Faro system was analyzed by means of a modeling approach to obtain information on the functionality and health status of the system and to verify whether this has undergone any alterations in the last decade. The analyses carried out show a clear difference between the three-year period 2003–2005 and the two-year period 2018–2019, highlighting how environmental changes, such as the increase in temperature, have led to higher costs of system functioning in the last two years. The mesozooplankton community has changed both in terms of abundance of organisms and in terms of organization and functionality.

People Prefer Greener Corridors: Evidence from Linking the Patterns of Tree and Shrub Diversity and Users’ Preferences in Lisbon’s Green Corridors

Despite its importance as a component of urban green spaces, as far as we are aware no study has focused on plant diversity in urban green corridors (GCs). Therefore, this study aimed at: (i) characterizing tree and shrub communities in Lisbon’s GCs and (ii) assessing whether GCs’ users value trees and shrubs. We counted Lisbon’s GCs users in the same places where we assessed the tree and shrub community. Along the nine GCs, we observed trees and shrubs belonging to 70 species, distributed across 35 families with most (≥50%) species and plants being trees, exotic, pollinated by insects, with fruit dispersion by animals, evergreen leaves, and producing dry fruits. Most GCs had a similar number of users (20–30 users h−1 survey−1) except for those of Central and Ribeirinho, which were more frequented (60 and 100 users h−1 survey−1, respectively). Most users (≥50%) were adults, walking accompanied, and performing leisure activities. Finally, the number of users was shown to be influenced by: (i) tree and shrub relative abundance, confirming that users preferred greener corridors; and (ii) function(s), showing that users preferred the most multifunctional GCs (i.e., GCs fulfilling ecological, cultural, and recreational functions). Our data suggest that Lisbon’s GCs favor more the inclusion of citizens than ecological functionality and resilience.

Assessment of Dam-Induced Changes in Ecogeomorphological Behaviour and Fluvial Functionality in the Damodar River, West Bengal, India

Anthropogenic interventions in the form of dams and barrages often alter the fluvial functionality and ecogeomorphological (geomorphology, hydrology, and ecology) behaviour of the river systems. The present work examines the environmental flow, channel metamorphosis, and fluvial functionality of Damodar River in the context of Damodar Valley Corporation (DVC) dams and development. The structural (dams, barrages, weirs, etc.) and non-structural (urban-industrial and agricultural disposal with effluents, sand mining, etc.) interventions hinder the ecological functionality of the river. This study portrays that the eco-geomorphological behaviour and fluvial functionality of the river have changed due to flow alteration and diversion by dams and barrages and due to the urban-industrial and agricultural growth in the basin area. These changes have affected riverine ecological integrity. The ecological functionality level of this study area ranges from 85 to 181 i.e. poor to good-fair. The ecological functionality level in sample channel sections (i.e., immediate upstream and downstream of Durgapur Barrage) is poor, and the value ranges from 61 to 100 due to the hydrological impact of the barrage and the Durgapur urban-industrial belt. This assessment work would help to restore the fluvial environment for humans as well as riverine biota.

A novel biome concept and classification system based on bioclimate and vegetation – a Neotropical assay

The knowledge of biomes as large-scale ecosystem units has benefited from advances in the ecological and evolutionary sciences. Despite this, a universal biome classification system that also allows a standardized nomenclature has not yet been achieved. We propose a comprehensive and hierarchical classification method and nomenclature to define biomes based on a set of bioclimatic variables and their corresponding vegetation structure and ecological functionality. This method uses three hierarchical biome levels: Zonal biome (Macrobiome), Biome and Regional biome. Biome nomenclature incorporates both bioclimatic and vegetation characterization (i.e. formation). Bioclimate characterization basically includes precipitation rate and thermicity. The description of plant formations encompasses vegetation structure, physiognomy and foliage phenology. Since the available systems tend to underestimate the complexity and diversity of tropical ecosystems, we have tested our approach in the biogeographical area of the Neotropics. Our proposal includes a bioclimatic characterization of the main 16 Neotropical plant formations identified. This method provides a framework that (1) enables biome distribution and changes to be projected from bioclimatic data; (2) allows all biomes to be named according to a globally standardized scheme; and (3) integrates various ecological biome approaches with the contributions of the European and North American vegetation classification systems.

METHODOLOGICAL PROPOSALS FOR ADDRESSING AGROECOLOGICAL DESIGN IN PERIURBAN AREAS: A CASE STUDY IN THE EDGES OF MILAN (ITALY)

This study aims to develop an ecological-based design model, applying the theoretical basis of landscape ecology and phytosociology on a pilot area located in the Milan South-Eastern rural edges. The goal was to integrate an all-inclusive approach for agroecological regeneration. Three main guidelines were identified: 1. the rehabilitation of landscape texture; 2. internal diversification; 3. environmental consistency. The study led to a global evaluation of the ecological functionality of the different environmental compartments, analysing their weaknesses and resiliences. Consequently, design criterions were defined, regarding the landscape level (ecotopes diversification) and the single ecotope level (vegetational standards), reconfiguring the current uses and functions and enhancing the biological and structural diversity within the agroecosystem. Finally, an evaluation of the benefits on ecological functionality was carried out, as well as a qualitative assessment of the ecosystem services that can be delivered. This approach enabled to make direct comparisons between actual and project scenarios, supporting the readability of the rebalancing effects attainable on the environmental, social and economic scale.

Resilience in Diet-quality Strategies of Mixed Native and Non-native Herbivore Communities in Semi-arid and Sub-humid Savanna Ecosystem

The global climate change processes are expected to impact African savanna ecosystems in their ecological functionality and availability of food resources for herbivores. To understand the feeding responses of large savanna herbivores placed to space-constrained and two environmentally distinct (semi-arid versus sub-humid savanna) conditions, we investigated the diet quality of five species living in a mixed community of species native and non-native for the West African savanna and compared them between the two sites as a proxy for a potential ecosystem shift due to climate change. Grazers and mixed feeders maintained diet quality in most nutrients at similar levels, while browser’s diet had lower nitrogen and fibres, specifically lignin, and more calcium in semi-arid savanna. Our findings suggest that adaptation to different ecosystems with no possibility to leave the area required changes in feeding behaviour across feeding types to maintain diet quality, especially mixed feeders escaped the competition with zebras for grasses in sub-humid savanna by switching to browse. Pure browser experienced reduced diet quality in drier environment and may potentially become susceptible to ecosystem changes. Conservation strategies should facilitate both, animals’ adequate behavioural responses together with nutritional resilience in changing savanna landscapes.

THE ROLE AND SOCIO-ECOLOGICAL FUNCTIONALITY OF TAX TOOLS IN THE CONTEXT OF THE INDUSTRY 4.0 PARADIGM

The tax system of any state is designed to ensure and regulate economic processes in order to support development and solve socio-ecological and economic problems. The tools of the tax legislation of the Russian Federation, being primarily a mechanism for generating state revenues, have an impact on the development of organizations, industries, industries by creating demand for goods, works, and services, regulating prices and inflationary processes, as well as maintaining social justice in society. However, the revision of the current tax tools with the analysis of current trends is quite rare, while the change of economic development paradigms requires constant attention and timely adjustment. The article considers the specified problems and selects ways to express the socio-ecological functional of taxes in the context of industrial transformation. Based on the analysis of the current legislation, the authors highlight tax instruments that have an impact on economic entities in the context of the development of automation and data exchange, evaluate their effectiveness. The results of the study can be used to adapt the tax policy of the state in the context of the “Industry 4.0” paradigm.

Forest and Landscape Restoration: A Review Emphasizing Principles, Concepts, and Practices

Forest and Landscape Restoration (FLR) is considered worldwide as a powerful approach to recover ecological functionality and to improve human well-being in degraded and deforested landscapes. The literature produced by FLR programs could be a valuable tool to understand how they align with the existing principles of FLR. We conducted a systematic qualitative review to identify the main FLR concepts and definitions adopted in the literature from 1980 to 2017 and the underlying actions commonly suggested to enable FLR implementation. We identified three domains and 12 main associated principles—(i) Project management and governance domain contains five principles: (a) Landscape scale, (b) Prioritization, (c) Legal and normative compliance, (d) Participation, (e) Adaptive management; (ii) Human aspect domain with four principles: (a) Enhance livelihoods, (b) Inclusiveness and equity, (c) Economic diversification, (d) Capacity building; (iii) Ecological Aspects domain with three principles: (a) Biodiversity conservation, (b) Landscape heterogeneity and connectivity, (c) Provision of ecosystem goods and services. Our results showcase variations in FLR principles and how they are linked with practice, especially regarding the lack of social aspects in FLR projects. Finally, we provide a starting point for future tools aiming to improve guidance frameworks for FLR.

Species-level classification of urban trees from worldview-2 imagery in Debrecen, Hungary: an effective tool for planning a comprehensive green network to reduce dust pollution

Urban green spaces of cities are crucial elements of city structure that ensure habitat for species and ecological functionality of habitat patches, maintain biodiversity, and provide environmental services. However, detailed maps intended for planning and improving the existing network require a quick and effective technique for assessing the possibilities. Multispectral imagery is an accessible source for species-level classification of urban trees. Using a multispectral image from the WorldView–2 satellite sensor, we classified six of the most common urban tree species in Debrecen, Hungary. Maximum Likelihood (ML) and Support Vector Machine (SVM) classifiers were applied to different numbers of the MNF-transformed bands. The best overall accuracy was achieved with the ML algorithm applied to the first four transformed bands (75.1%), and with the SVM algorithm applied to eight bands (71.0%). In general, ML performed better than SVM. Despite the relatively low number of spectral bands, we achieved moderately good accuracy for basic vegetation mapping, which can be used in spatial planning and decision making. In a future interdisciplinary research study, we could merge the classification results with the dust adsorption capacity of individual species to assess the reduction of dust pollution by urban trees.
