Divja Slovenija: Plavček, prepoznaven po značilni obarvanosti

Spoznajte dvoživko, ki je dobila ime po barvi telesa v času parjenja. Plavček je živalska vrsta, ki je predstavljena tudi v dokumentarnem filmu Divja Slovenija, kjer si lahko ogledate pestro favno in floro Slovenije.

Plavček (Rana arvalis) je 4 do 8 cm velika barska žaba. Zanj je značilna čokata postava, koničast gobec, belo-rumenkast trebuh in rjavkasto-siv hrbet.

Samci pridobijo v obdobju parjenja značilno modro barvo, po kateri je vrsta dobila ime in je v naravi zelo prepoznavna. Žaba plavček raste počasi in spolno zrelost doseže šele med drugim in četrtim letom.

Živijo med 10 in 15 let, a večina osebkov te starosti ne doživi, saj v naravi nanje preži veliko nevarnosti, kot so ptiči, kače, ribe in male zveri. Največ pa jih pogine v obdobju, ko so še paglavci.

Plavček ogrožen zaradi onesnaženosti in posegov v vodni sistem

Plavčka ogrožajo predvsem posegi človeka v njegov življenjski prostor in vodni režim mokrišč. Za vse žabe velja, da so zelo občutljive na onesnaževanje voda. Na območju močvirja se pogosto odlagajo odpadki, po drugi strani pa se mnogo mokrišč zasipava. Vsak takšen poseg pa pomeni izginjanje habitata za ogrožene vrste žab. V Sloveniji je plavček na rdečem seznamu označen kot ranljiva vrsta.

Močvirje je njegov dom

Plavček se prehranjuje z različnimi nevretenčarji, kot so deževniki, polži, žuželke in njihove ličinke ter pajki, včasih lovi tudi paglavce in druge manjše žabe. Najbolje se počuti v poplavnih logih, na močvirnih travnikih, v času parjenja pa v manjših mlakah in jarkih z vodo. V dokumentarnem filmu Divja Slovenija je predstavljen v času parjenja.

Če filma še niste videli ali pa bi ga želeli ponovno pogledati, to lahko storite v spletnem kinu Art kino mreže Slovenije, na tem naslovu je dostopen v slovenski in angleški različici.

_hjClosedSurveyInvites Hotjar cookie. This cookie is set once a visitor interacts with a Survey invitation modal popup. It is used to ensure that the same invite does not re-appear if it has already been shown. 365 days _hjDonePolls Hotjar cookie. This cookie is set once a visitor completes a poll using the Feedback Poll widget. It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms. N/A _hjptid This cookie is set for logged in users of Hotjar, who have Admin Team Member permissions. It is used during pricing experiments to show the Admin consistent pricing across the site. Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
