D2.1 - Report on the beta version of the dynamic model
This report presents the beta version of the metacommunity model developed in WP2 to investigate biodiversity dynamics in drying river networks.
D2.2 - R package for the simulation model of meta-community dynamics
The model of metacommunity dynamics in drying river networks (see D2.3) was encapsulated in the R package “cantal.” It allows to simulate a wide range of drying scenarios, potential interspecific heterogeneity in dispersal abilities and resistance to drying. It can also simulate varying scenarios of drying events based on empirical data.
D2.3 - Report on the final version of the model and the simulation results
This report presents the final version of the metacommunity model developed in WP2 (“Predicting biodiversity changes in DRNs”) to investigate biodiversity dynamics in drying river networks.

D2.7 - A graphical tool to simulate meta-community dynamics
In this deliverable, we present the graphical tool to simulate meta-community dynamics in the drying river networks studied by the project DRYvER.

This report from the DRYvER project analyzes the dynamics of aquatic macroinvertebrate metacommunities across various ecoregions to elucidate the spatiotemporal responses within two primary biogeographical settings: the Palearctic and the Neotropical regions (i.e., realms). This study focuses on the impact of drying on macroinvertebrate diversity within both perennial and intermittent streams across DRNs in Europe (Palearctic) and CELAC — Latin America and the Caribbean—(Neotropical)
D3.1 - River network meta-ecosystem model

This report contains the details of developing this model.

In this report, we aimed to investigate the stability of river food webs in the face of drying. We sampled aquatic macroinvertebrate and fish communities and assessed hydrological conditions over the course of one year. We studied biodiversity, taxon-specific biomass using image analysis, and estimated secondary productivity of invertebrates and fish.

D4.1 - Conceptual model of the ecosystem services provision of DRNs and its application at the focal DRN level
This report presents a first part which develops a conceptual model of ecosystem service provisioning in Drying River Networks and a second part with a modelling exercise estimating the provision of a selection of key ecosystem services in the 6 DRNs of the project.
D4.2 - EU-scale maps of ecosystem services provision
The objectives of this deliverable were to model the provisioning of four ecosystem services (water provisioning, dilution capacity, flood regulation, and drought regulation) in river networks, including both perennial and intermittent rivers, and to describe the regional patterns of these services across Europe.
D4.4 - Criteria and principles for the valuation of ES of DRN across Europe
As the valuation of ecosystem services (ES) in DRNs across Europe needs to rely on benefit transfer (BT) practices, the goal of this deliverable is to derive a set of guidelines to improve the future implementation of BT practices in this context. We summarise the findings of the literature review that produced economic values for securing or improving riverine ecosystem services under drying conditions.

With this policy report we list the policy measures aimed at securing biodiversity, water quality and ecosystem services and summarize results of stakeholder workshops from Spain, Hungary, France, Finland, Croatia and Czech Republic. We study horizontal policy coherence between EU policies that are relevant for the adaptive management of the DRNs. We provide policy recommendations for improved coherence and to encourage adaptive management within the DRN.
D5.5 - Priority area mapping tool
The DRYvER-OptimApp is a collaborative tool designed to identify and prioritize critical areas for conservation and restoration of Drying River Networks (DRNs). Its main objective is to help find key areas for maintaining significant values of biodiversity, ecological functions, and ecosystem services in the six European DRNs that serve as case studies of the DRYvER project. It also provides insightful information on the importance of drying reaches for maintaining such values. Additionally, the app also offers the possibility to classify these identified priority areas based on their suitability for either conservation or restoration purposes. This tool was built as a Shiny app and is based on Systematic Conservation Planning (SCP) principles.
