The Colorado River Delta and California's Central Valley are critical regions for many migrating North American landbirds
<p>Migration is an important component of some species full annual cycle. California's Central Valley and the Colorado River Delta provide important riparian and wetland habitats for migrating waterbirds in the arid west of North America, but little is known about whether these locations are important at the population level to migrating landbirds. We used eBird Status and Trends abundance data to quantify the importance of the Central Valley and Colorado River Delta to landbirds by estimating the proportion of the breeding population of 112 species that use each site during migration. We found that ~17 million landbirds use the Colorado River Delta in the spring and ~14 million in the fall. Across four study regions in the Central Valley, up to ~65 million landbirds migrate through in the spring and up to ~48 million in the fall. In the spring and fall, respectively, up to 37 and up to 30 species had at least 1% of their continental population migrate through the study regions. We also quantified the spatial concentration of each species across latitudinal transects to determine the extent to which study regions were acting as migratory bottlenecks. Landbird abundances were spatially concentrated in study regions 29.4% of all migration weeks, indicating that each study region acts as a migratory bottleneck. This application of eBird data is a powerful approach to quantifying the importance of sites to migrating birds. Our results provide evidence of population-level importance of the Central Valley and Colorado River Delta for many migratory landbirds.</p>

Data from: Reconstructing the evolutionary history of an endangered subspecies across the changing landscape of the Great Central Valley of California.
Identifying historic patterns of population genetic diversity and connectivity is a primary challenge in efforts to re-establish the processes that have generated and maintained genetic variation across natural landscapes. The challenge of reconstructing pattern and process is even greater in highly altered landscapes where population extinctions and dramatic demographic fluctuations in remnant populations may have substantially altered, if not eliminated, historic patterns. Here, we seek to reconstruct historic patterns of diversity and connectivity in an endangered subspecies of woodrat that now occupies only 1-2 remnant locations within the highly altered landscape of the Great Central Valley of California. We examine patterns of diversity and connectivity using 14 microsatellite loci and sequence data from a mitochondrial locus and a nuclear intron. We reconstruct temporal change in habitat availability to establish several historical scenarios that could have led to contemporary patterns of diversity, and use an approximate Bayesian computation approach to test which of these scenarios is most consistent with our observed data. We find that the Central Valley populations harbour unique genetic variation coupled with a history of admixture between two well-differentiated species of woodrats that are currently restricted to the woodlands flanking the Valley. Our simulations also show that certain commonly used analytical approaches may fail to recover a history of admixture when populations experience severe bottlenecks subsequent to hybridization. Overall our study shows the strength of combining empirical and simulation analyses to recover the history of populations occupying highly altered landscapes.

Subspecies and Distribution. H.a.aquaticusOgilby,1841—WAfricafromGuineaandSierraLeonetoGhana. H.a.bates:Lydekker,1906—Nigeria,Cameroon,andpresumablyneighboringcountries. H. a. cottoni Lydekker, 1906 — Republic of the Congo, DR Congo, and presumably Uganda. The Water Chevrotain reportedly has a disjunct distribution, occurring in coastal forests from West Africa and in the rainforests of Central Africa from Nigeria to DR Congo, marginally entering Uganda. It has been listed for the following countries in Central Africa: Angola (Cabinda), Cameroon, Central African Republic, DR Congo, Equatorial Guinea, Gabon, Nigeria, Republic of the Congo, and Uganda (Semliki Valley). A record from Angola's Lunda Norte Province, near the Cassai River,is the southernmost record of the species. The species' status in some countries remains unclear. It is apparently absent from the Republic of Benin and Togo (but the speciesis listed as probable in the Ot Basin in Togo); its supposed occurrence in Guinea Bissau and Senegal remains unsupported by evidence. The species was listed for Sierra Leone, although its presence had been called into question. Photographic evidence seems to clarify that the species occurs in Sierra Leone. In 1850, a specimen was recorded from Gambia, but the present status of the species is unclear. Local people report the species from the Boké Préfecture in NW Guinea, which might be the northernmost area from which the species has been recently reported. Extensive field and market surveys there and in the southern Guinea savanna belt did notfind evidence for the species' presence. in Tragulidae
