Incentive-based strategies such as conservation easements and short-term management agreements are popular tools for conserving biodiversity on private lands. Billions of dollars are spent by government and private conservation organizations to support land conservation. Although much of conservation biology focuses on reserve design, these methods are often ineffective at optimizing the protec...

Landsat 7's recent malfunctioning will result in significant gaps in long-term satellite monitoring of Earth, affecting not only the research of the Earth science community but also conservation users of these data. To determine whether or how important Landsat monitoring is for conservation and natural resource management, we reviewed the Landsat program's history with special emphasis on the ...

Restoration ecology is undergoing rapid growth as an academic discipline, similar to that experienced by conservation biology over the last 15 years. Restoration ecology and conservation biology share many underlying biodiversity goals, but di€er in striking ways. Using data from published literature in these two ®elds, I document that conservation biology has been more zoological, more descrip...

Systematic conservation planning (SCP) is a field of conservation biology concerned with delivering on-the-ground actions that achieve conservation goals. It describes a set of operational models that cover both design and implementation of conservation, with a strong focus on mobilising the collective action typically required to implement conservation. SCP, as it was originally described, was...

The high demand for conservation work is creating a need for conservation-focused training of scientists. Although many people with postsecondary degrees in biology are finding careers outside academia, many programs and mentors continue to prepare students to follow-in-the-footsteps of their professors. Unfortunately, information regarding how to prepare for today's conservation-based job mark...

Founder populations in reintroduction programmes can experience a genetic bottleneck simply because of their small size. The influence of reproductive skew brought on by polygynous or polyandrous mating systems in these populations can exacerbate already difficult conservation genetic problems, such as inbreeding depression and loss of adaptive potential. Without an understanding of reproductiv...

Conservation and history of architecture are separate disciplines, each having their own concepts. Conservation regards the protection of a historical property and the continued life of a monument, while the history of architecture tries to identify and understand the architecture of the past. Conservation deals with historical monuments that constitute remaining evidence of architectural histo...

Perhans, K. 2008. Cost-efficient conservation strategies for boreal forest biodiversity. Doctor’s dissertation. ISSN 1652-6880, ISBN 978-91-85913-72-5 Long and intensive forest management has made conservation measures in the forest landscape necessary to maintain forest biodiversity. The most common measure is to set aside land for conservation purposes. This, however, requires large financial...
