Northern Fur Seal New and Recolonized Breeding Sites Have Population Growth Rates Among the Fastest of Any Fur Seal

Northern Fur Seals at South Farallon Islands, California.

Understanding the colonization or recolonization of breeding sites used by colonially breeding animals is fundamental to metapopulation theory and has practical applications in conservation biology. Historically, pinniped species (seals and sea lions) were heavily exploited worldwide, resulting in some breeding colonies becoming extirpated. As populations recover, some abandoned sites may be recolonized or new sites can … Read more

Seeing Spots: New Study Reveals the Giraffe Babies Inherit Spot Patterns from Their Mothers and Certain Spot Traits Improve Newborn Survival

50-year-old Hypothesis Confirmed with Modern Techniques The beautiful coat patterns of giraffes are individually unique and don’t change with age, but their origins and purpose were a mystery. A new study found wild giraffe spot pattern traits were heritable, passed down from mother to offspring, and certain spot traits improved survival of newborns. Quantifying heritability … Read more

·         A new study found community-based wildlife conservation in Tanzania can quickly result in clear ecological success by benefitting giraffes and other wildlife species. Arusha, TANZANIA, 10 August 2018- Community-based natural resource management is a grassroots conservation tool that has become one of the dominant paradigms of natural resource conservation worldwide. In Tanzania, efforts to … Read more

Everything you wanted to know about wildland forest fires but were afraid to ask

Regrowth after a high-severity forest fire. The past three decades of science that has found fires, including large high-severity fires, are an ecologically essential part of forest ecosystems and create highly biodiverse wildlife habitat.

A team of fire ecologists released a report this week titled “Everything You Wanted To Know About Wildland Fires” summarizing the state of knowledge about forest fires on public lands. This report comes just days after the US Congress passed the Wildfire Suppression Funding and Forest Management Activities Act as part of the federal omnibus … Read more

New Study Will Help Giraffe Conservation

A group of Masai Giraffes in the Tarangire Ecosystem.

How do you reverse a population decline and save an endangered species? This is the central question in conservation biology and it is the core of my scientific work. A population of animals like giraffes is almost always made up of smaller groups of animals that we call subpopulations. The animals in the subpopulations are … Read more

How many species of Giraffe are there?

Some people might be confused by the media announcing that there are “now” four species of giraffes, followed shortly thereafter by the IUCN press release that there is one species of giraffe (with nine subspecies) now considered to be Vulnerable to Extinction on the Red List.  The IUCN currently recognizes one species of giraffe with … Read more
