Background: Theobroma cacao L., the source of cocoa, is a crop of significant economic value around the world. To facilitate the study of gene function in cacao we have developed a rapid Agrobacterium-mediated transient genetic transformation protocol. Here we present a detailed methodology for our transformation assay, as well as...

Abstract
Background
We used multi-season occupancy analyses to model 2 fates of northern spotted owl territories in
relation to habitat amount, habitat fragmentation, and the presence of barred owls in Washington State,
USA, 1989–2005. Local colonization is the probability a territory unoccupied by a spotted owl in year i would
be occupied...

Conservation investment in management of at-risk species can be less costly than a delay-and-repair
approach implemented after species receive legal protection. The United States Endangered Species
Act candidate species designation represents an opportunity to implement proactive management to
avoid future listing. Such efforts require substantial investments, and the challenge becomes...

Research on regulatory mechanisms in biological populations often focuses on environmental covariates. An integrated
approach that combines environmental indices with organismal-level information can provide additional insight on
regulatory mechanisms. Survival of spring/summer Snake River Chinook salmon (Oncorhynchus tshawytscha) is consistently
low whereas some adjacent populations with similar life histories experience...

Marine teleost fishes often experience over 99% mortality in the early life stages (eggs and larvae), yet larval survival is essential to population sustainability. Marine fish larvae from a wide range of families display elaborate, delicate features that bear little resemblance to adult forms and hinder their swimming escape ability...

Penicillium chrysogenum is the main industrial producer of the β-lactam antibiotic penicillin, the most commonly used drug in the treatment of bacterial infections. Recently, a functional MAT1-1 locus encoding the α-box transcription factor MAT1-1-1 was discovered to control sexual development in P. chrysogenum. As only little was known from any organism...
Early-successional stages have been truncated and altered in many western U.S. forest landscapes by
planting conifers, controlling competing vegetation, suppressing fire, and focusing on maintaining late-seral
species and undisturbed riparian zones. Declining area of early-successional stages may be reducing
resilience and sustainability on landscapes that experience elevated disturbance related to...
Dibenzo(def,p)chrysene (DBC), (also known as dibenzo[a,l]pyrene), is a high molecular weight
polycyclic aromatic hydrocarbon (PAH) found in the environment, including food, produced by
the incomplete combustion of hydrocarbons. DBC, classified by IARC as a 2A probable human
carcinogen, has a relative potency factor (RPF) in animal cancer models 30-fold higher...
