331-Towards a multisensor station for automated biodiversity monitoring

  1. https://www.sciencedirect.com/science/article/pii/S1439179122000032
    Large-scale and long-term automated monitoring of biodiversity (as established for climate research) does not exist, among other reasons, because the required technology is not currently available, yet. It is therefore crucial to adapt existing technologies for the development of automated, reliable, and verifiable biodiversity monitoring. Similar to climate research, we need “weather stations for species monitoring” in addition to remote sensing.

    We do not discuss here optimized monitoring schemes or approaches that include volunteers, ecological experiments, or the search for drivers. Our focus is tools that facilitate autonomous biodiversity monitoring. It is possible to construct automatized multisensor stations for monitoring species diversity (AMMODs) using available technologies. These technologies include bioacoustic sensors, tailored imaging systems, automated image analysis, DNA-barcoding, analyses of volatile organic compounds (VOCs) and discriminators to distinguish specimens by their inherent characteristics (such as movement and velocity) using artificial intelligence approaches or multivariate discriminators. Thus, it is possible to detect simultaneously and with high temporal resolution various classes of organisms present in a locality.

    In addition to species detection, the recording of behavior, metadata such as ambient environmental parameters and abiotic factors are important variables to be correlated with spatio-temporal species occurrence. The on-site temperature regime, precipitation, wind force and direction, hydrographic situation or information on the directional movement add significant eco-taxonomical context to individual recordings and their interpretation.

    The AMMOD stations allow the continuous detection of a large range of terrestrial meso‑ and macrofaunal species and environmental parameters and deliver consistent and standardized data as required in monitoring and environmental research (Lombard et al., 2019). The main challenges are (1) in the field of computer science (pattern recognition, change detection, motion sensors and comparison of environmental signals with reference databases), (2) the completion of reference and training datasets (also for little known taxa), (3) the improvement and integration of existing sensors and hardware solutions, (4) the adaptation of sensors to target species (e.g. large vs. small mammals), and (5) in the assembly, testing, and long-term operation of a network of AMMODs (Fig. 1). For the interpretation of large monitoring data sets we also need databases with species-specific trait data, ideally as international databases with the possibility to select the properties of regional faunas.

    sing a camera trap 24 hours a day at a single location and for a longer period, the system can count and measure the number of insects present more efficiently and less expensively than a human counter can. Thanks to the system, observation can also be carried out at multiple locations simultaneously. Using the software means that scientists no longer have to catch the insects, which saves a lot of time. Naturalis 'trains' the software using a photo database of several million photos collected by the amateurs and specialists at Waarneming.nl. The size and quality of this database is unique in the world and at present, the Netherlands is the only country in the world in which this development is possible.

    With the modern system of image recognition incorporated into these cameras, researchers expect that the counting of insects will be much easier. It will consequently be possible to observe at multiple locations simultaneously. Using these automatic counting cameras could contribute to the setting up of a national counting network for the insect population. This might be a follow-up to recent research.

    The key functions of the package make use of the free command line software ExifTool (Harvey 2015) via system calls to extract metadata from camera trap images in JPEG format. camtrapR provides extensive automation of processes, performs rigorous consistency checks on input data and has no inherent limitation in terms of the image number held in the data management system.

    camtrapR was designed for studies utilizing arrays of camera trap stations, each consisting of one or more (often two) camera trap units (termed cameras for sake of simplicity). Cameras within a station are set in relative proximity to each other compared to between-station distances.
    https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/2041-210X.12600
    Digital images contain metadata in standardized Exif format, for example date and time, geotags, camera settings, ambient data, trigger event number and many more. In addition, users can assign information to images via custom metadata tags in image management software, for example species or individual identification, sex, behaviour, group size counts or group membership of individuals. These metadata tags become part of the images and are portable without depending on a relational database structure. Both types of metadata can be extracted, tabulated and used subsequently, for example for data filtering prior to analyses. The package vignettes contain a performance estimate for metadata extraction using ExifTool.

    We recommend the free and open-source software DigiKam (www.digikam.org) for tagging because it provides a customizable, hierarchical tag structure and has powerful filtering, querying and batch-tagging capabilities. Adobe Lightroom and Adobe Bridge are also suitable.

    The Geocaching app c:geo (only available for Android) gives the user several options for maps - live maps via Google, Google Sat View, OSM and a few others - but also an option to use various offline maps (OSM maps that are available via third-party websites such as Mapsforge). Those maps are typically downloaded at the level of State, Province, or Country (deepening on size). See https://manual.cgeo.org/en/offlinemaps 1. Having a similar option in the app might skirt some of the issues related to who will host the map data or traffic issues. If a user want to use OSM maps, they would need to download the OSM maps to their device. Another advantage is that it is available without data (remote locations).

  9. Temp distribution in my city on a 32°C day.
    Lucky to be living by the water, next to a park, in a street lined with trees => in the blue-green rather than the orange-red. #hitteplan #heatwave Fellow citizens of #Utrecht can explore their street here: https://gemu.maps.arcgis.com/apps/webappviewer/index.html?id=d3b93cf65c8b4f999f7615d1ec7409ee
    We willen dat de temperatuur in de stad niet meer dan 5 graden warmer aanvoelt dan buiten de stad. Op deze kaart ziet u de gevoelstemperatuur op een hete dag met een luchttemperatuur van 32 graden. De temperatuur voelt in de stad meer dan 7 graden warmer dan aan de rand van de stad. Dat komt doordat er niet veel bomen zijn en weinig schaduw is. Ook is er veel verharding, zoals straten en stoepen. Die houden warmte vast.

  15. Op maandagavond 14 maart organiseert de Nicolaas G. Pierson Foundation, het wetenschappelijk bureau van de Partij voor de Dieren, een online symposium over het belang van groene gemeenten. Er zijn nog enkele plaatsen beschikbaar.

    Vergroening van de gebouwde omgeving is gunstig voor mens en dier. Uit onderzoek blijkt dat het onder meer de biodiversiteit en de luchtkwaliteit versterkt en van groot belang is voor de waterberging en verkoeling op warme dagen. De laatste jaren dringt dit ook steeds meer door bij beleidsmakers en het grote publiek: groen is hip. Maar ondanks de toegenomen populariteit blijft natuur in de praktijk toch nog vaak het ondergeschoven kindje, in plaats van een vanzelfsprekend onderdeel van gemeenteplannen. Gemeenten zijn zich wel bewust van de energie- en mobiliteitstransitie, maar zien groen toch nog vooral als een kostenpost. Of ze leggen de nadruk vooral op natuur als een ecologische en recreatieve dienst voor mensen en vergeten daarbij de eigen waarde van dieren en natuur los van het nut voor de mens. Nieuwe woonwijken worden nog steeds gepland ten koste van dieren en natuur, zonder eisen te stellen aan bijvoorbeeld minimale percentages groen, wateropvangvoorzieningen en nestmogelijkheden. Er wordt zelfs natuur vernietigd voor woningbouw, met de belofte het groen elders te ‘compenseren’. En wanneer het wel lukt om groene plannen door te zetten, gaat het in de uitvoering of het onderhoud nog vaak genoeg mis.
    Het is duidelijk: het is de hoogste tijd voor een fundamentele koerswijziging.

    De sprekers van deze avond zijn Robbert Snep en Fabrice Ottburg. Zij zijn academici met een missie, die vanuit inhoud en passie zowel de natuur als de samenleving een stap verder willen helpen. Ze zullen de laatste kennis delen op het gebied van de voordelen en mogelijkheden van groene gemeenten, maar zullen ook de obstakels en valkuilen benoemen. Aan de hand van vragen uit het publiek zal Marianne Thieme, directeur van de Nicolaas G. Pierson Foundation, verder met hen in gesprek gaan.

  16. Van stikstofoverschot tot biodiversiteitsverlies

    – Dinsdag 25 oktober 2022 –

    Provinciaal Natuurcentrum, Genk

    Vlaanderen heeft een stikstofoverschot: meer dan 80 % van onze (vaak Europees beschermde) natuur lijdt eronder. Vooral intensieve veeteelt is de oorzaak, naast de uitstoot van industrie, verkeer en huishoudens. De stikstofuitstoot heeft zware gevolgen voor de biodiversiteit: graslanden verarmen, bramen en netels overwoekeren de typische bosflora, bomen verzwakken en sterven af, de paarse heide kleurt bruin, waterplassen lijden onder zuurstoftekort.

    Deze lezing gaat dieper in op de problematiek van het stikstofoverschot, de gevolgen ervan voor de biodiversiteit en mogelijke oplossingen.

  19. Thought this recent paper might be of interest to this group: Deriving indicators of biodiversity change from unstructured community-contributed data 4. It’s pretty much about how to overcome the biases and “messiness” of iNat data to find patterns and see change through time. I apologize that it’s not open-access - Wiley’s OA fees are prohibitive, and since this was grant-funded work we couldn’t afford it. Our co-author did a nice tweet-summary 4 of it where you can see some of the figures describing the work. I’m also more than happy to send the pdf to anyone who’s interested in reading the whole thing!

  20. Opportunistic and unstructured observations of biodiversity crowdsourced from volunteers, community, and citizen scientists make up an increasingly large proportion of our global biodiversity knowledge. This incredible wealth of information exists in real time at both high resolutions and large extents of space, time, and taxonomy, thus holding huge potential to fill gaps in global biodiversity monitoring coverage in a cost-effective way. Yet, the full potential of these data to provide essential indicators of biodiversity change for both research and management remains mostly unrealized, in large part due to the prevailing perception that the lack of standardization presents an unsurmountable barrier. In this paper, we provide an overview of the main challenges of working with unstructured community-contributed data and synthesize the four fundamental approaches to overcome these challenges and extract useful inferences of biodiversity change, namely: 1) reverse-engineering survey structure; 2) borrowing strength across taxa; 3) modeling the observation process, and; 4) integrating standardized data sources. To illustrate each of these approaches, we provide examples comparing community-contributed observations crowdsourced via iNaturalist with long-term standardized monitoring surveys for a subset of rocky intertidal organisms on the California coast from 2010 to 2019. We conclude by highlighting ways forward for the successful integration of unstructured community-contributed observations within the global ecosystem of biodiversity change monitoring tools. Our ultimate goal is to update the prevailing perception among researchers and practitioners that unstructured community-contributed observations of biodiversity are too noisy to use, and help establish this data stream as a key tool for research and management.

  • What happens if we mow our urban lawns only 1-2x/year? Insects come back (of course), especially those that can fly 🐝🪲
    Interestingly, perceived 'pest' species do not benefit from this untidyness - on the contrary.

    Our new meta-analysis in now online:
    https://sciencedirect.com/science/article/abs/pii/S1618866722002576
    Urbanization is an important driver of global insect decline. Yet, recent studies have demonstrated the potential of greenspaces in cities to promote biodiversity conservation. One of many factors negatively affecting arthropods in urban areas are unsuitable habitats, as non-woody greenspaces predominantly consist of manicured lawns. Maintenance practices such as high mowing frequencies, can have direct and indirect negative impacts on the local flora and fauna. The present study examines the effects of different mowing regimes on arthropod abundance and diversity by conducting meta-analyses of studies assessing the effect of mowing on arthropod abundance (46 datasets) and taxa richness (23 datasets) in urban environments. Due to a geographical bias in the literature, only data from the temperate, northern hemisphere are analyzed. While our meta-analysis on arthropod abundance showed a medium positive effect (effect size: g = 0.54) of reduced mowing, the cumulative positive effect of reduced mowing on arthropod taxa richness was large (g = 1.25). Grouping the studies not only resulted in lower heterogeneity, but also showed that manicured lawns disproportionately favor the abundance of “pest” species as well as ground-dwelling arthropods. There was also a significantly higher abundance of winged insects on sites with reduced mowing as compared to arthropods without wings. Overall, the findings of the present meta-analysis strongly support the notion that a reduction in mowing frequencies in urban greenspaces benefits insect biodiversity.
