Special Issue Information

Dear Colleagues,

Monitoring fast changes and long-term trends in biodiversity driven by widespread environmental alterations in the Anthropocene is a critical international endeavor increasingly supported by remotely-sensed Earth observations (RS/EO)—even more so if we consider the need to track the progress of global conservation initiatives and policy such as the CBD’s Aichi Targets, the UN’s Sustainable Development Goals or the EU’s Habitat Directive. In a wider sense, RS/EO is critical to monitor biodiversity changing face, which includes species range shifts, community reassembly, and biological invasions up to changes in ecosystem and landscape functioning. Ultimately, this will allow assessing how these changes affect the vulnerability of life on Earth and the benefits people extract from nature.

Despite the inherent complexity and multidimensional nature of the Biodiversity concept, entailing several hierarchical levels (from genes to biomes), distinct facets (structure, composition and function), and several spatial scales (from local to global), the current “Golden Age” of RS/EO, with increasingly diverse platforms and enhanced spectral, spatial, and temporal coverage, enables assessing these dimensions and their scalar inter-connections. From airborne to satellite platforms, RS/EO together with field-surveys and innovative techniques related to bioacoustics, sensor networks, camera trapping, radiotracking or environmental metagenomics enable monitoring several dimensions of biodiversity in unprecedented and novel ways. This has been made possible also due to advances in modeling approaches (correlative, mechanistic, process-based), ecoinformatics, cloud-based computing, time series analysis, and spatial statistics allowing the modeling, mapping, and detection of biological and ecological change.

In this Special Issue dedicated to “Biodiversity Monitoring”, we are calling for innovative, integrative and multidisciplinary contributions covering biodiversity’s multiple dimensions in the terrestrial, freshwater, and marine domains which combine RS/EO with multiple biodiversity observation data-streams (e.g., from field surveillance time series to citizen-science programs or metabarcoding), to better understand the drivers and improve the monitoring of biodiversity spatiotemporal change.

Migratory birds are particularly exposed to habitat changes in their breeding and non-breeding grounds. Remote sensing technologies offer an excellent opportunity to monitor species’ habitats from space at unprecedented spatiotemporal scales. We analyzed if remotely sensed ecosystem functioning attributes (EFAs) adequately predict the spatiotemporal variation of the Woodcock’s (Scolopax rusticola) relative abundance in southwest Europe, during autumn migration and wintering periods. We used data gathered from Woodcock monitoring through citizen science (N = 355,654 hunting trips) between 2009 and 2018. We computed a comprehensive set of EFAs on a weekly basis from three MODIS satellite products: enhanced vegetation index (EVI), tasseled cap transformation (TCT), and land surface temperature (LST). We developed generalized linear mixed models to explore the predictive power of EFAs on Woodcock’s abundance during the non-breeding season. Results showed that Woodcock abundance is correlated with spatiotemporal dynamics in primary productivity (measured through the EVI), water cycle dynamics (wetness component of TCT), and surface energy balance (LST) in both periods. Our findings underline the potential of combining citizen science and remote sensing data to monitor migratory birds throughout their life cycles—an issue of critical importance to ensure adequate habitat management in the non-breeding areas.

Seagrass meadows are undergoing significant decline locally and globally from human and climatic impacts. Seagrass decline also impacts seagrass-dependent macrofauna benthic activity, interrupts their vital linkage with adjacent habitats, and creates broader degradation through the ecosystem. Seagrass variability (gain and loss) is a driver of marine species diversity. Still, our understanding of macrofauna benthic activity distribution and their response to seagrass variability from remotely sensed drone imagery is limited. Hence, it is critical to develop fine-scale seasonal change detection techniques appropriate to the scale of variability that will apply to dynamic marine environments. Therefore, this research tested the performance of the VIS and VIS+NIR sensors from proximal low altitude remotely piloted aircraft system (RPAS) to detect fine-scale seasonal seagrass variability using spectral indices and a supervised machine learning classification technique. Furthermore, this research also attempted to identify and quantify macrofauna benthic activity from their feeding burrows and their response to seagrass variability. The results from VIS (visible spectrum) and VIS+NIR (visible and near-infrared spectrum) sensors produced a 90–98% classification accuracy. This accuracy established that the spectral indices were fundamental in this study to identify and classify seagrass density. The other important finding revealed that seagrass-associated macrofauna benthic activity showed increased or decreased abundance and distribution with seasonal seagrass variability from drone high spatial resolution orthomosaics. These results are important for seagrass conservation because managers can quickly detect fine-scale seasonal changes and take mitigation actions before the decline of this keystone species affects the entire ecosystem. Moreover, proximal low-altitude, remotely sensed time-series seasonal data provided valuable contributions for documenting spatial ecological seasonal change in this dynamic marine environment.

Urgent action needs to be taken to halt global biodiversity crisis. To be effective in the implementation of such action, managers and policy-makers need updated information on the status and trends of biodiversity. Here, we test the ability of remotely sensed ecosystem functioning attributes (EFAs) to predict the distribution of 73 bird species with different life-history traits. We run ensemble species distribution models (SDMs) trained with bird atlas data and 12 EFAs describing different dimensions of carbon cycle and surface energy balance. Our ensemble SDMs—exclusively based on EFAs—hold a high predictive capacity across 71 target species (up to 0.94 and 0.79 of Area Under the ROC curve and true skill statistic (TSS)). Our results showed the life-history traits did not significantly affect SDM performance. Overall, minimum Enhanced Vegetation Index (EVI) and maximum Albedo values (descriptors of primary productivity and energy balance) were the most important predictors across our bird community. Our approach leverages the existing atlas data and provides an alternative method to monitor inter-annual bird habitat dynamics from space in the absence of long-term biodiversity monitoring schemes. This study illustrates the great potential that satellite remote sensing can contribute to the Aichi Biodiversity Targets and to the Essential Biodiversity Variables framework (EBV class “Species distribution”).
