Today, changes to breeding habitats, coastal development, oil spills, introduced feral animals and bycatch in fisheries are among the threats that impact on seabird populations. In Aust ...

The effect of habitat transformation on dung beetle assemblages in the north-western Free State was investigated by comparing the fauna of a nature reserve (Sandveld Nature Reserve (SNR) (27°37'S;25°46'E» with that on neighbouring farms. Dung beetle sampling was done in four different localities wit ...

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
