Promising sources for breeding golden currant (<i>Ribes aureum</i> Pursh)

Spatiotemporal variation in range-wide Golden-cheeked Warbler breeding habitat

Habitat availability ultimately limits the distribution and abundance of wildlife species. Consequently, it is paramount to identify where wildlife habitat is and understand how it changes over time in order to implement large-scale wildlife conservation plans. Yet, no work has quantified the degree of change in range-wide breeding habitat for the Golden-cheeked Warbler (Setophaga chrysoparia),...

Cisgenesis Is a Promising Approach for Fast, Acceptable and Safe Breeding of Pip Fruit

Introgression of traits from wild germplasm into pip fruit cultivars by means of classical breeding is painstakingly slow. Introgression of e.g., the apple scab resistance gene Vf from Malus floribunda 821 into marketable high quality apple cultivars took approximately 50 years. In the mean time the Vf resistance is being broken down in Europe. For durable resistance, different resistance genes...

Methods to Combine Estimated Breeding Values Obtained from Separate Sources

Separate estimates of breeding value can be combined using meta-analysis if a combined analysis of all data is not possible or efficient. Computation is fast but not exact if the reliabilities of the separate estimates are approximate, if the extent of overlap of the datasets is unknown, or if selection has occurred across the datasets. Selection index methods were used to combine single-trait ...

Camphor as a promising insecticude for control

Sources, sinks, and drains in double breeding bird species?

The recognition of a second breeding season in some migratory bird species by Rohwer et al. (1) creates an interesting scenario for conserving migratory bird populations. Previously, conservation biologists assessed sources as large undisturbed habitats and sinks as degraded breeding grounds (2), and treated fragmented and deforested habitats in nonbreeding “wintering” areas as drains on the po...
