Het JKB Klimaatkandidatendebat
Maarten van Lonen De Noordpool is niet meer wat zij vroeger was. De klimaatcrisis gaat daar momenteel veel sneller dan in de rest van de wereld. Zien we daarom steeds meer broedende ganzen in Nederland? Wordt het noorden minder aantrekkelijk voor hen? Tijdens deze lezing legt Maarten Loonen uit dat het broeden van ganzen in Nederland niets te maken heeft met klimaatverandering. Maar de snelle opwarming vraagt wel om aanpassingen als ze op Spitsbergen willen blijven broeden. Kunnen de ganzen het wel bijhouden?
Niet alleen de ganzen maar ook de mensen in het noordpoolgebied hebben te maken met grote veranderingen. De temperatuur stijgt er sneller, maar daarnaast gebeuren er ook steeds vaker onverwachte ongelukken. Nieuwe rampen zorgen voor een bijstelling van het beeld over de gevolgen van de opwarming van de aarde. Het is niet alleen meer de temperatuur die oploopt. Daarmee is de ervaring van het noordpoolgebied een belangrijke waarschuwing voor de onvoorspelbaarheid die ons nog te wachten staat. Een reden om sneller iets te doen aan onze CO2 uitstoot!
Dr. Maarten Loonen is universitair hoofddocent Arctische Ecologie aan de Rijksuniversiteit Groningen. Sinds 1988 brengt hij elke zomer twee maanden door op Spitsbergen, in de meest noordelijke stad ter wereld. Spitsbergen is uitgegroeid tot de grootste internationale onderzoeksbasis in het noordpoolgebied. Hier bestudeert hij brandganzen in het Arctische ecosysteem. De Noordpool warmt veel sneller op dan de rest van de wereld, Loonen maakte de gevolgen van de klimaatcrisis voor mensen die in de regio wonen van dichtbij mee. Als groot voorstander van het serieus nemen van klimaatopwarming probeert hij het bewustzijn te vergroten voor een vermindering van de koolstofdioxide uitstoot.
https://blog.nefit-bosch.nl/monoblock-of-split/
Lucht/water-warmtepompen zijn er in zowel Monoblock-, als Split-uitvoering. Wat zijn de verschillen?
Grofweg kun je zeggen dat de split-uitvoering een erfenis is van de airconditioning. De monoblocks zijn een doorontwikkeling vanuit warmtepomptechniek. Bij een monoblock zit de condensor in de buitenunit. Dit betekent dat de leidingen die van buiten naar binnen gaan gevuld zijn met water. Bij een split-uitvoering zijn deze gevuld met koudemiddel. Split-units zijn compacter en goedkoper, maar de monoblock heeft weer een beter rendement. Zowel de hybride als all-electric warmtepompen zijn in deze twee uitvoeringen op de markt.
Elke situatie is anders
Er kunnen verschillende redenen zijn om voor split of monoblock te kiezen: de prestaties, de formaten, de prijzen of de voorkeur van de installateur. En dan nog is ook het type woning een factor van betekenis. Is het een bestaande of nieuwe woning, gestapelde of grondgebonden woning en wat is de mate van isolatie? Op dit moment is de markt voor split en monoblock ongeveer evenredig verdeeld.
Prestaties
Bij de monoblock-uitvoering zit de condensor in de buitenunit. Dit buitendeel is qua formaat groter dan de split-uitvoering. Dat is niet voor niets. De monoblock heeft namelijk een groter verdamperoppervlak beschikbaar voor de warmteoverdracht van de energie van de buitenlucht. Daardoor haalt de monoblock een hoger rendement (COP). Doordat hij effectiever energie uit de buitenlucht kan halen, heeft hij een hoger temperatuurbereik. En dat kan weer handig zijn voor in de renovatie, waar soms wat hogere aanvoertemperaturen gevraagd worden dan in de nieuwbouw. Ook voor het bereiden van tapwater kan dit gunstig uitpakken. Er zit ook een grotere ventilator op. Dit betekent dat eenzelfde hoeveel lucht verzet kan worden met een lager toerental. Dit betekent minder bewegingen en dus ook minder geluidsproductie. Het monoblock van Nefit Enviline kan daarnaast ook verder terugmoduleren.
Monoblock buitenunits
Afmetingen en opstelplaats
Een split-uitvoering is kleiner en compacter. Dit betekent dat het buitendeel makkelijker weg te werken is, en aan de gevel kan hangen. Een monoblock buitenunit is forser, en dus moet rekening gehouden worden met de windbelasting. Indien er geen plek is voor het buitendeel op een plat dak, carport of tuin, dan kan het reden zijn om voor de meer compacte split te kiezen.
Prijs
Een belangrijk aspect: de split-uitvoering van de lucht/water-warmtepomp is goedkoper. Dat heeft vooral te maken met de productiemethode. De buitendelen van split-systemen worden geproduceerd door de bedrijven die ook de airco-buitendelen in grote massa produceren. Daar zitten internationaal grote aantallen in, en dat heeft zijn weerslag op de prijs. Monoblock-units worden door het Bosch-concern in Zweden gebouwd, op basis van eigen technisch ontwerp. Het verschil in techniek en schaalgrootte zie je terug in de prijs.

iNaturalist Identification 1.2 available for download from “Transfer Big Files”:
http://tbf.me/a/BxAlcw (The link expires on February 10th).
Fixes included: configurable main window height ; API daily quota enforced (10k requests/day) ; “only_id=true” and “id_below” in observations pages requests ; grouped observations data download (resulting in half less API requests) ; ignore observations with identifications, still returned despite the filter “identified=false” for reviewing only the “Unknown” (cf. “User has opted-out of Community Taxon”).
Tracking: in every API request, the header ‘user-agent’ identifies the tool as “iNaturalist Identification/1.2”.
How to reduce the number of API requests?
Select “Skip observations submitted after: YYYY” at application startup.
Or use the same option in the settings file, for instance: SkipObservationsSubmittedAfter=2017
Less results requires less requests to keep these results uptodate.
Available for download:
iNaturalist Identification 1.2 - Deliverable.zip
It contains a minimal setup of the tool.
iNaturalist Identification 1.2 - Deliverable ; Observations preloaded.zip
It contains a setup of the tool and 7 search queries (Benin, Bolivia, Denmark, France, Netherlands, Philippines, Taiwan) and 8 AI based filters configured, and the data of all “Unknown” observations matching these search queries (51850 observations). About these search queries, see also:
https://forum.inaturalist.org/t/are-there-too-many-new-observations-to-identify/16109/92
iNaturalist Identification 1.2 - Other observations preloaded.zip
22 search queries (Russia, and many places in America: Central America, South America, Mexico, Bahamas, Greater Antilles, Lesser Antilles, Alabama, Arizona, Arkansas, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas) and the data of all “Unknown” observations matching these search queries (201000 observations).
Setup:
Unzip. No installation or uninstallation process.
Get a token from this URL and copy/paste it in the “iNatIdentify - Settings.txt” file:
https://www.inaturalist.org/users/api_token
The token is required and enables the tool to submit IDs and comments on behalf of you.
Simply double-click on “iNatIdentify.exe” to run the tool.
Presentations of the tool while developing it:

https://forum.inaturalist.org/t/search-and-filter-identifications/1304/50
ndpoint – one request for each unknown observation in a given set – which may not be a good thing. it probably also hammers the observation API endpoint to get the observations, though in this case at least it can do this as one request per 200 observations. the response from the observation endpoint is still fairly large. so there’s probably a lot of data being retrieved and transferred in that case.)
I made every effort possible to spare the server resources. This tool makes 2 requests for each observation in a result page (200 observations/page): 1 request to get the observation data and 1 request to get the AI suggestions (including the taxa descriptions). The process is limited to a total of 60 requests/minute. Parallelization helps to reach this limit, although it takes several seconds to get the response to a request.
Note that I distribute many preloaded observations (observations data + AI suggestions + taxonomy) with the tool, so that you can start using the tool and ID many observations without almost downloading anything. (In that case it would spare the server ressources better than using the web application instead).
Should this tool have a large success (?..), and should the server resources become an issue, it would be then possible to create a feature request for providing bulk data to download (that would NOT need to be updated often). I mean providing files to download similar to those presently generated by the tool, for every place defined in the search queries:
About the web application:
There are things in the web application that do not spare the server resources as much as possible:
https://forum.inaturalist.org/t/ideas-for-a-revamped-explore-observations-search-page/8439/104
https://forum.inaturalist.org/t/on-observation-detail-page-show-on-the-map-any-taxon-selected/19561/5
(Ultimately, only a server side measure could tell for what the resources are spent.)
true, but there are some recommended practices (https://www.inaturalist.org/pages/api+recommended+practices), and in the context of what you’ve written about your tool, these points seem particularly relevant:
- Please keep requests to about 1 per second, and around 10k API requests a day
- We may block IPs that consistently exceed these limits
- The API is meant to be used for building applications and for fetching small to medium batches of data. It is not meant to be a way to download data in bulk
it looks to me like a user just running your tool without understanding the nuances of what it is doing might easily inadvertently exceed the 10k req/day limit, leading to a block of their IP. so i guess something like this just makes me nervous for the user who uses it in unexpected ways.
All the photos are not referenced in A, but are referenced in B.
This is a reason to go on performing B, and not only A.
It does take a very long time to download many observations.
Only then, the user defined taxon based filters can be applied to the observations downloaded.
(An observation (data + AI) is downloaded only once and saved on the disk).
I never got my IP blocked because of the amount downloaded, even when downloading observations almost non-stop for several days. So, we need not be nervous about possible consequences for the users of the tool. (And I tested the tool for a long period of time at 90 requests/minute, without issue, so I am even more confident at 60 requests/minute).
I got blocked soon (but only for a very short period of time) whenever the scheduling was buggy, after a burst of requests was submitted in a very short period of time.
I figured out that even 60 requests/minutes was not supported for the downloading of taxonomic data, so that a slower scheduling is automatically applied in that case. Such taxonomic requests would happen if the taxonomic cache is deleted (you might wish to delete it if you want to get the common names in a different language). Such taxonomic requests also happen when the user defines a new filter, for generating an “Overview” taxonomy in relation to the new taxon based filter. I made extensive tests to avoid being blocked ever.
Should the “HTTP Error 429, Too Many Requests” still happen, the tool would immediately suspend all requests for 5 minutes and display a message “Suspended…” in the status bar.
The user may also reduce the nominal frequency, in the settings file, if something bad happens:
(I anticipate a possible future change in the rules or in the server behavior, without blocking the users until a tool update is made available).
This concern depends on your taxon based filter(s). For instance, “Phylum Tracheophyta” is a very high rank filter and you get too many observations to review. On the contrary, I could review all unidentified “Subfamily Caesalpinioideae” (lower rank filter) observations in Benin, Bolivia, Philippines, Taiwan (there were not that many). Note that filtering at a low taxonomic rank has motivated the development of this tool. The need for such a tool is lower if your interest is taxonomically broader.
How to reduce the number of observations downloaded by the tool?
Another aspect (also relevant to the web application) is that you want to see unknown observations that are still unknown. At startup, the tool has to request again pages of observations, in order to remove from the local cache (and from the display) the observations that do not match anymore the search query(ies), I mean to remove the observations that are not anymore unknown.
Note that this could be optimized by a new API feature, for providing in one request/response all the observations IDs matching a search query (without providing any observation data at all).
In short, the ability to define AI-based-and-custom-(low-rank)-taxon-based filters requires (in general) to download many observations (once), as long as the API does not offer “AI-assisted occurrence searches” (this topic). Then, as for the web application, it is required to keep uptodate what is displayed (to remove results not relevant anymore). The tool presently offers options to reduce the number of requests performed.
New API features (an AI based filter (this topic) ; a request to get all observations IDs matching a search query, without getting any other data than the IDs) could further reduce the usage of server resources.
BTW, another API feature that could help (at the margin) would be filtering API results by the observation ID, instead of filtering by the date submitted. I mean: a request to get (pages of) observations with IDs lower than 60000000 for instance (approximately equivalent to a date submitted earlier than “Sep 18, 2020”). Because of time zones, these filters are not equivalent. At some point, if we don’t want to miss observations, it is needed to submit overlapping (+/- 1 day) requests, and this is what the tool does. (The reason is that a request is over after we retrieved 50 pages of 200 observations/page. Another request, with another date filter, is required to get the next observations).
One may answer that, if I need, I may try to take into account the observation time zone (date submitted), to end up with something equivalent to an ID based filter. While trying, I found soon 2 observations at almost the same location in Florida that were registered with different time zones (with a gap of several hours). I didn’t investigate further.
Anyway, this would become pointless if there would exist “a request to get all observations IDs matching a search query, without getting any other data than the IDs” as suggested above.

Community-powered biodiversity conservation: how your observations can guide management on the California coast
Over the last decade, tens of thousands of community scientists and volunteer naturalists together have collected hundreds of thousands of observations of biodiversity up and down the California coast. Boosted by community science campaigns such as Snapshot Cal Coast and crowdsourced via the iNaturalist platform, these community-contributed observations now represent one of the largest and fastest-growing datasets of biodiversity available in real-time and throughout the California coast.
In this Webinar, Dr. Gio Rapacciuolo will show us how this somewhat messy but incredibly rich stream of information can be translated into timely insights useful to manage and conserve biodiversity on our coast. Join us to learn how your volunteered observations are now more crucial than ever to safeguard biodiversity on our beloved coast.

Umweltschutzorganisationen in Deutschland schlagen Alarm. Die Zahl der eingeschleppten und eingewanderten Kleinbären und kleinen Raubtiere steigt und steigt. In Deutschland steht ein „Mehrfrontenkrieg“ bevor. Von Norden her drängen Waschbär, Mink und Marderhund nach Bayern, Österreich und Frankreich. Aus dem Süden kommt der eigentlich in Südosteuropa und in Afrika heimische Goldschakal. Wie viele dieser vor allem nachtaktiven Räuber sich in Deutschland aufhalten, kann nur geschätzt werden. Doch es gibt andere Zahlen, die aufhorchen lassen: So wurden 2016 über 25.000 Marderhunde in Deutschland und Österreich geschossen – fast 20 Prozent mehr als im Vorjahr. Bei Waschbären sind es in fünf Jahren 150 Prozent mehr getötete Tiere gewesen. Das liegt nicht an besonders schießwütigen Jägern, was sogar der BUND Naturschutz zugeben muss, sondern an der rasanten Ausbreitung dieser Arten. Jedes dieser Raubtiere ist anders, hat andere Fähigkeiten und Strategien. Die Eindringlinge bedrohen vor allem die, die schon lange unter der Zerstörung und dem zunehmenden Schwund ihres Lebensraumes leiden und deshalb vielerorts vom Aussterben bedroht sind: Bodenbrüter, Singvögel und Amphibien.
