Morphology, ecology and distribution of threatened species in Cacatuidae family

Neprestani negativni antropogeni utjecaj dovodi do ugroženosti vrsta i povećanog rizika od izumiranja istih. Ovaj rad donosi kratak pregled ugroženih vrsta iz porodice Cacatuidae, uključujući njihovu morfologiju, ekologiju, distribuciju te kategoriju i razloge ugroženosti. Kao glavni razlozi ugroženosti navode se kontinuirana deforestacija, krivolov i ilegalna trgovina te globalno zatopljenje. Navedeni problemi uzrokuju smanjenje populacija, često bez mogućnosti oporavka te zbog toga brojnost vrsta kontinuirano pada. Kako bi se usporio nestanak vrsta, provode se brojne edukacije, istraživanja i projekti, a na nacionalnoj i internacionalnoj razini donose se propisi i mjere za zaštitu vrsta i njihovih staništa.Continuous negative anthropogenic influence leads to endangered species and increased risk of extinction. This paper provides a brief overview of the endangered species of the Cacatuidae family, including their morphology, ecology, distribution, and the category and causes of endangerment. The main threats include continuous deforestation, poaching, illegal trade and global warming. These problems cause decline of populations, often with no recovery potential, and therefore the number of species continues to decline. To slow down the disappearance of species, numerous education and research projects are carried out, while regulations and measures for the protection of species and their habitats are adopted at national and international level
