11 - Routes, Tracks en Trips methode om afwezigheid aan te geven naast presentie in iNaturalist

(1-3, Suikerunie,belarus, observa)
Normaal kun je in iNaturalist alleen maar ruwe aanwezigheidsdata aangeven. Absentie kan nu met de "Trip" methode. Het handigst is dit om bij een nachtvlinderval te doen maar je kunt ook aangeven naar welke soorten je gezocht hebt (target list) , in welk gebied je gezocht hebt (Het Roege Bos) en hoe lang je naar de soort op zoek bent geweest (Search interval). Als een soort niet aangegeven is dan was deze specifieke soort afwezig.
Een Trip is een aangepaste journaal post zoals dit stukje tekst ook is, dus met een titel, een beschrijving maar ook een "Zoekgebied" en "Zoek duur" wat berekend wordt uit Start Tijdstip en Stop Tijdstip.
Met een "Trip" kun je extra achtergrond informatie geven over aan maar vooral afwezigheid van soorten. En ook kun je je waarneemfrequentie opgeven wat extra informatie geeft bij het bekijken van de verspreidingsdata. De normale iNaturalist gegevens zijn altijd "aanwezigheids" gegevens.

Wat is een goede naam voor een trip?

Trip, Route (monitoringsroute)

Transect (uit waarneming.nl, maar kan deze term niet bewaard worden als er een gpsroute meegeleverd gaat worden?)
Traject
Reis?

Een "Trip" geef extra informatie aan je opgeslagen gegevens:

Waar je naar gezocht hebt (De Doelsoortenlijst)
Waar je gekeken hebt (Het zoek gebied)
Op welk tijdstip je gekeken hebt (Het zoek interval)
De soorten op je doelsoortenlijst die je waargenomen hebt worden beschouwd als "aanwezig". En soorten die je niet gezien hebt worden als "afwezig" beschouwd.
Door op het veld 'Tabulate Presence Absence Data From Trips' te klikken wordt een tabel aangemaakt van aan en afwezige soorten van een trip en verwante waarnemingen.

Trips enable the collection of presence-absence data by adding context to your observations
Why Presence-absence data include information about sampling effort which is useful for scientific analyses like distribution modeling (raw iNaturalist observations are 'presence-only' data).

How A trip adds context to your observations by recording:

What you searched for (target list)
Where you searched (search area)
When you searched (search interval)
Species on your target list that you were able to observe within the search area and interval are interpreted as presences. While species on your target list that you were unable to observe are interpreted as absences. Click 'Tabulate Presence Absence Data From Trips' to generate a table of presence-absence records for a species from trips and associated observations.

Trips on iNaturalist are extensions of journal posts. Like journal posts they have titles and descriptions where you can describe the trip. They also have data that capture the search interval (e.g. April 18, 2019 4:00 PM - April 18, 2019 4:40 PM) and search area (Latitude, Longitude, Radius). Distance and Number of Observers are entered by the user to capture more detail about earch effort. Duration is calculated automatically from the search interval.
Trips also record information on what you searched for in the form of a target list. A target list is a non-overlapping set of taxa or species that were searched for. Any species covered by the target list (ie a species on the list or a descendant of a taxon on the list) that is not observed within the radius and duration of this trip is interpreted as an absence. Blue circles indicate the existence of observations of taxa covered by the target list made within within the search area and interval. Note: the target list displayed here has cleans up overlapping taxa. For example, if you entered a genus and a species within it on your target list, only the genus is displayed. Also, we recommend that you don't use trips with obscured obs (ie observations you obscure or observations of taxa automatically obscured) as efforts to mask true locations may lead to misleading results.

How to tabulate data from a trip

To generate presence absence data from a trip, first enter a single species like Western Fence Lizard (Sceloporus occidentalis) to filter trips relevant to that species. You can also optionally filter trips by place, month, or year
The resulting table of trips will include an occupancy column for the species populated with 1s (presences) or 0s (absences) accordingly
You can also access this table in a machine readable JSON format

oes your camera record accuracy? If it does, you may need to send an example image or two to the staff at help@inaturalist.org. (the forum will modify the original image) You’re right that it would be a bug - this feature was added in 2018. https://github.com/inaturalist/inaturalist/commit/6633cf76cd0baca1b809b6cdb8d12aa23df067f9 1

How to find a trip

You can search for trips relevant to a taxon (ie trips with target lists covering the taxon), place (ie trips with latitudes and longitudes within the place), and month or year (ie trips with start dates on that month or year)

To view a single trip you can click on the trip id

You can generate a table of presence-absence records for a species from trips and associated observations

And you can make trips of your own

How to view a trip

Trips on iNaturalist are extensions of journal posts. Like journal posts they have titles and descriptions where you can describe the trip. They also have data that capture the search interval (e.g. April 18, 2019 4:00 PM - April 18, 2019 4:40 PM) and search area (Latitude, Longitude, Radius). Distance and Number of Observers are entered by the user to capture more detail about earch effort. Duration is calculated automatically from the search interval.

Trips also record information on what you searched for in the form of a target list. A target list is a non-overlapping set of taxa or species that were searched for. Any species covered by the target list (ie a species on the list or a descendant of a taxon on the list) that is not observed within the radius and duration of this trip is interpreted as an absence. Blue circles indicate the existence of observations of taxa covered by the target list made within within the search area and interval. Note: the target list displayed here has cleans up overlapping taxa. For example, if you entered a genus and a species within it on your target list, only the genus is displayed. Also, we recommend that you don't use trips with obscured obs (ie observations you obscure or observations of taxa automatically obscured) as efforts to mask true locations may lead to misleading results.

How to create a trip

Like journal posts, your trip must have a Title and can have a Description to give some context.

You can optionally record the distance you traveled and the number of observes to better describe your search effort

The time interval during which you were searching is defined by start and end times.

The area within which you were searching is defined by a circle with a center (latitude and longitude) and a radius in meters. You can create this circle by centering it on an iNaturalist place (e.g. Ring Mountain Open Space Preserve), an address, by positioning it manually on the map, or by entering the latitude, longitude and radius directly.

What you were searching for is defined by your target list. These can be species or coarser groups of species. They will be interpreted as a non-overlapping set made up of the coarsest taxa on your list. Its important not to put anything on your list that you did not attempt to detect. If you have a coarse grouping on your list like Lady Beetles, this means that you attempted to detect and observe each species in this group at least once.

You can populate your target list by selecting one of the high level groupings on the left

Or by manually searching for a species or grouping

When you're done, save your trip to finish later, or publish it to share it publically.
