• Identifying strategic early investments to assist the integration and synthesis of science priorities and to address known priority gaps; • Conducting competitive processes for issuing awards for addressing the science needs; • Continuing refinement of Science plan in coordination with partners through the life of the Program. NOAA anticipates being able to issue a focused Federal Funding Opp...
The development of species priorities for conservation at local or regional scales (for example, within a state or province) poses an interesting paradox. One the one hand, locally or regionally-derived species priorities may lead to greater interest in and resources directed to biodiversity conservation by local or regional institutions. On the other hand, locally or regionally-derived species...
Recovery planning is a key component of many threatened species conservation initiatives and can be a powerful awareness raising tool. One of the largest impediments to conservation efforts in the Pacific region however, is the lack of ecological data and its subsequent effects on the development of feasible and useful recovery plans for threatened species. Without these plans, the understaffed...
Freshwater ecosystems are among the most endangered habitats on Earth, with thousands of animal species known to be threatened or already extinct. Reliable monitoring of threatened organisms is crucial for data-driven conservation actions but remains a challenge owing to nonstandardized methods that depend on practical and taxonomic expertise, which is rapidly declining. Here, we show that a di...

Threatened species become increasingly difficult to detect as their populations decline. Managers of such cryptic threatened species face several dilemmas: if they are not sure the species is present, should they continue to manage for that species or invest the limited resources in surveying? We find optimal solutions to this problem using a Partially Observable Markov Decision Process and rul...

A set of polymorphic loci was characterised using an enrichment library for the Australian alpine specialist, the chameleon grasshopper (Kosciuscola tristis), an atypical grasshopper known for its remarkable temperature-controlled colour change. The number of alleles per locus ranged from three to 20 and observed heterozygosity from 0.16 to 0.76. These are the first microsatellite markers for a...
T he Endangered Species Act of 1973 addresses the market failure associated with the unpriced social benefits of such species. Robert Barnwell Roosevelt might have been envisioning such an act in his 1865 book Superior Fishing, where he wrote: ‘‘By these means can the seductive little beauties, whether of the feathered, furred, or scaly tribe . . . be preserved through endless time in undiminis...
