Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Parallels in the sequential organization of birdsong and human speech. [PDF]
, 2019 Human speech possesses a rich hierarchical structure that allows for meaning to be altered by words spaced far apart in time. Conversely, the sequential structure of nonhuman communication is thought to follow non-hierarchical Markovian dynamics ...

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, EarlyView.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, EarlyView.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

Why Do Birds Flock? A Role for Opioids in the Reinforcement of Gregarious Social Interactions
Frontiers in Physiology, 2019 The formation of social groups provides safety and opportunities for individuals to develop and practice important social skills. However, joining a social group does not result in any form of obvious, immediate reinforcement (e.g., it does not result in

Prevalence of traded bird species in key biodiversity areas
Conservation Biology, EarlyView.Abstract The use and trade of biodiversity involve tens of thousands of species that are exploited at a range of scales, intensities, and degrees of sustainability. As a result, some are highly threatened. Key biodiversity areas (KBAs) are sites of significance for the persistence of biodiversity identified nationally based on standardized criteria ...

Significant Instances in Motor Gestures of Different Songbird Species
Frontiers in Physics, 2019 The nervous system representation of a motor program is an open problem for most behaviors. In birdsong production, it has been proposed that some special temporal instances, linked to significant aspects of the motor gestures used to generate the song ...

Determining Presence/Absence and Abundance of Declining Shrubland-Dependent Songbirds in Human-created Shrublands in Southeastern New Hampshire [PDF]
, 2016 Shrubland habitat and wildlife species have been declining throughout most of New England since the 1950s. Many songbirds have been declining at a rate of 4 to 7 percent per year in New England, and these species require large openings to breed.
