News Articles Featuring Derek Lee

Another rare spotless giraffe found-the first ever seen in the wild

There has been another sighting of spotless giraffes in Namibia

Masai giraffes more endangered than previously thought

Giraffes in eastern Africa may be even more endangered than previously thought. A new study led by researchers at Penn State revealed that populations of Masai giraffes separated geographically by the Great Rift Valley have not interbred — or exchanged genetic material — in more than a thousand years, and in some cases hundreds of thousands of years.

Male giraffes have social connections beyond their own community

Nature is not the mechanical clinking of cogs, preordained by certain ecological laws. It is dynamic – animals and plants form complex and flexible relationships in their individual, contingent contexts. A new study revealing the differing sexual politics in giraffe society illustrates just that. The study shows that male giraffes are more socially connected than females.

Male giraffes are more socially connected than females

Although female giraffes have closer “friends” than male giraffes, male giraffes have more “acquaintances” than females, according to a new study by an international team that includes a Penn State biologist. The study demonstrates that giraffes form a complex multilevel society that is driven by differences in the social connections among individuals, which could have conservation implications for the endangered giraffes.

Whole-Genome Data Point to Four Species of Giraffe

The genome sequences of 51 giraffes from all over Africa contribute to the latest attempt in an ongoing pursuit to pin down a species number.

Friends matter: More sociable giraffes live longer

Adult female giraffes that group together with more of their peers live longer than less sociable individuals, according to a five-year study of giraffes in Tanzania.

Could spotted owls benefit from forest fires?

It may seem counterintuitive, but forest fires are actually beneficial to spotted owls, according to Penn State biologist Derek Lee.

Human presence weakens social relationships of wild giraffes

Living in close proximity to human settlements disturbs giraffe social networks, with animals having weaker bonds and fewer interactions with other giraffes, according to a new study by a team including a Penn State biologist.

Wildfires Can Reduce Biodiversity. Can Biodiversity Be Used to Reduce Wildfires?

Over the past several months, wildfires have burned a huge portion of Australia’s natural landscape. We’re talking almost 18 million acres of bushland, forest and national parks. This was not your typical annual wildfire.

Improving success of giraffe translocations

Researchers advise that Giraffes being translocated for conservation purposes should be moved in groups that contain at least 30 females and three males to ensure long-term population success.
