“دببة هجينة” تظهر في جزر الكوريل الروسية وخبراء يحذرون من خطرها على البشر

ما يعرفه ريفو عن الخبر

تشكل هجائن الدببة القطبية والبنية في جزر الكوريل خطراً كبيراً على البشر بسبب غرائزها الغذائية الموروثة.
تجمع هذه الهجائن بين الطبيعة اللاحمة للدب القطبي وعدوانية الدب البني مما يجعلها مفترسات خطيرة.
أدى تغير المناخ وذوبان الجليد إلى تداخل نطاقات انتشار الدببة القطبية والبنية مما أدى لظهور هذه الهجائن.
سُجلت حالات مماثلة في كندا عام 2006 وتعرف هذه الدببة هناك باسم بيزليز.

أدى التغير المناخي العالمي، إلى بحث الكائنات في البيئات المختلفة، عن بيئات جديدة خارج موائلها الطبيعية، وبالتالي، الاتصال مع أنواع أخرى أنتجت هجائن جديدة تحمل صفات الصنفين.
