^(a)

Climate change effect on different animals’ indicators that influence negatively the species performance (e.g. worst performance) expressed as a relative frequency (%).

^(b)

Climate change effect on different animals’ indicators that influence positively the species performance (e.g. better performance) expressed as a relative frequency (%).

^(c)

No change observed on performance.

^(d)

Not applicable.

⁽¹⁾

RF stands for relative frequency (%).

⁽²⁾

All species refer to bovine, ovine and caprine.
