Elephants: reproduction, respiration and reintroduction

The image shows a depiction of elephant copulation, acquired in Thailand where this practice remains common. Some time ago, Welsh Celtic elephants (Elephas (Palaeoloxodon) Cambriae) decided to abandon this activity, and this is presumed to be one cause of their extinction. The reasons for their decision remain unclear.

The second image shows a troop of Malawian aquatic elephants (Loxodonta africana aquaticus) crossing the River Shire (pron. Sheeray) earlier this month. Note the highly developed trunk which has a third eye at its tip, making it useful for vision and respiration simultaneously. Few other mammals have this facility. Rumours persist that a small community of Celtic aquatic elephants survive in Bala Lake, but this seems improbable.

The Bala rumour may become irrelevant next year after the reintroduction of Celtic elephants in Ceredigion: these will be released partly in an attempt to control the virulent invasive plant Miscanthus (elephant grass) that has self-sown in the neighbourhood of the IBERS experimental facility at Gogerddan.

For linguistic convenience, the reintroductions will be brought from Brittany, but they may well be crossed with the famously hardy and fecund Patagonian variety, giving a direct link back to the native species. During the Welsh migrations to South America 150 years ago, Welsh elephant numbers were already in steep decline, but a small number were taken with the emigrants to assist in cheesemaking. They took readily to the Argentinian climate and rapidly interbred with local elephants (Loxodonta americana patagoniae).
