I rinoceronti segnalano il loro sesso, età e l'eventuale disponibilità all'accoppiamento attraverso le loro feci. A suggerirlo è uno studio pubblicato mercoledì nella rivista Proceedings B, della Royal Society britannica, nel quale viene spiegato che questi mammiferi si servirebbero di "latrine comuni", come gli esseri umani usano i social media.
Un trio di ricercatori sudafricani e tedeschi ha analizzato l’odore degli escrementi di rinoceronti bianchi che vivono in libertà nella riserva di HluHluwe-Umfolozi del KwaZulu-Natal in Sudafrica, ricreandoli poi in laboratorio prima di diffonderli nel parco e osservare la reazione dei maschi.
Risultato: quando gli animali maschi percepiscono l'odore di altri "pretendenti", cercano di seguire le tracce; se percepiscono invece fragranze femminili restano nella zona, sperando in una possibilità di accoppiamento.
