Svetovni dan žab: 7 zanimivosti, ki jih o teh dvoživkah še niste vedeli

Poznamo več kot 7000 vrst žab, v Sloveniji jih živi 13.

Na Svetovni dan žab (20. marec) po vsem svetu potekajo različna izobraževanja o dvoživkah, ki imajo pomembno vlogo pri ravnovesju v naravi, ter ozaveščanje za njihovo ohranitev.

Žabe pri nas zaščitene

V ta namen smo poiskali nekaj zanimivosti o žabah pri nas. Ste vedeli, da so vse žabe v Sloveniji ogrožene in zaščitene?

  1. Vseh 13 živečih vrst žab v Sloveniji je uvrščeno na rdeči seznam in so zaščitene.
  2. Delijo se na kolutojezičnice (urhi), krastače (navadna in zelena), česnovke, rege, rjave žabe (sekulja, plavček, rosnica in laška žaba) ter zelene žabe (debeloglavka, zelena in pisana žaba).
  3. Laška žaba je ena najbolj ogroženih evropskih dvoživk, ki pri nas živi samo na širšem območju Vipavske doline ter v dolini reke Branice. Prav slovenske populacije pa so najpomembnejše v Evropi za dolgoročno preživetje te vrste.
  4. Zelena rega velja za majhno (3-5 cm), a najglasnejšo žabo pri nas, saj v obdobju parjenja, med aprilom in junijem, samci na mrestišča privabljajo samice z glasnim regljanjem ke-ke-ke-ke-ke-ke-ke, ki ga lahko slišimo tudi kilometre daleč.
  5. Urh (hribski in nižinski) se ob nevarnosti bliskovito zarije v mehko blatno na dno luže ali pa se refleksno vrže na hrbet in pokaže trebuh in tako opozori na svojo strupenost. Nižinski urh ima na trebuhu svarilni vzorec v oranžnem odtenku, hribski pa v rumenem.
  6. Sekulje pri nas živijo v alpskem svetu do 2000 m. Njihova skupinska mrestišča, ki tvorijo velike strnjene blazine, so tudi do 2 km oddaljena od kopenskih bivališč.
  7. Zelene krastače so razširjene po vsej Sloveniji, vendar redke. Dočakajo lahko starost več kot 20 let in so ene izmed najbolj prilagodljivih, saj so izredno odporne na vročino, izsušitev in slano vodo.

To function properly, Hotjar stores first-party cookies on your visitor's browser. Cookies are either set by the Hotjar script, or by visiting Hotjar's website. Displaying the correct content to your visitors without personally identifying anyone relies on Hotjar's cookies.

_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
