In the Great Basin, coniferous trees are expanding their range at a rate higher than any other time during Holocene. Approximately 90% of expansion has occurred in ecosystems previously dominated by sagebrush (Artemisia spp.). Transitions from open, steppe to woodlands considered threat greater sage-grouse (Centrocercus urophasianus), obligate gallinaceous bird that occupies approximately 56% i...

We describe a new species of Eupsophus from the Coastal Range of Southern Chile. The new taxon can be differentiated using an integrative taxonomic approach that includes advertisement call, reproductive mode, tadpoles, and mtDNA D-loop sequences. Based on karyological characters, the new species is assigned to the roseus Group (2N=30), and differs from all described species therein by having e...

Antllocyanin-rich crops have attracted attention in recent years because of their health benefits, and anthocyanin-rich tea is one of these crops. 'F95181' (Camellia sinensis) was developed for breeding anthosyanin-rich tea cultivars and registered as a new parental line 'Cha Chuukanbohon Nou 6' (C. sinensis) in 2004. 'F95181' was selected from an interspecific cross betweell C. taliensis (a wi...

Mayr and Johnson suggest that Spizella taverneri should be a subspecies of the biological species S. breweri, because it is possibly not reproductively isolated. We originally concluded that evidence from mitochondrial DNA sequences, habitat preferences, timing of breeding, vocalizations, and morphology supported the recognition of S. taverneri as a phylogenetic and biological species. Nothing ...

—Studies on breeding biology in Neotropical birds are crucial for understanding different aspects of their life histories and also for their conservation. We describe the nesting biology of the Red-crested Cardinal (Paroaria coronata) in central Argentina, a common suboscine that inhabits south temperate forests. We monitored 367 nests from October to February 2005–2008. Nest initiation followe...
