PHYSIOLOGICAL CHARACTERIZATION ON SEED AGING OF SIX NATIVE SHRUB SPECIES
… a consistent and adequate supply of seeds of native shrubs. However, annual seed production is erratic and seeds are usually short lived and insufficient for the reclamation projects. Seeds of six native shrub species including: Prunus virginiana, Prunus pensylvanica, Arctostaphylos uva-ursi, …

IMPACTS OF RDX SOIL CONTAMINATION ACROSS AN AGE GRADIENT FOR THE NATIVE SHRUB MORELLA CERIFERA.
… behavior in the environment. I quantified shrub growth responses to 1,3,5-trinitroperhydro-1,35-triazine (RDX) soil contamination across three life stages and I hypothesized that RDX would have the greatest impact on seed germination. Morella cerifera seeds were germinated on soils amended …

THE FEASIBILITY OF CHAPARRAL RESTORATION ON TYPE-CONVERTED SLOPES
… disturbances have caused type-conversion of native chaparral to non-native annual grasslands. Competition with non-native annual grasses hinders shrub establishment, presenting challenges in restoration. This study examined the feasibility of chaparral restoration in a Mediterranean-type …

MONITORAMENTO DO SOLO EM ÁREAS DEGRADADAS EM PROCESSO DE RECUPERAÇÃO NO MUNICÍPIO DE SÃO JOÃO DO CARIRI. SEMIÁRIDO PARAIBANO
… cultures (impacted area), witness area(native shrub or herbaceous vegetation) and external area. Therefore, two soil samples were collected at a profundity of 0,20 composing a composite sample. As for physical characteristics, a sandy texture was highlighted, both in internal and …

A Mechanistic and Landscape Scale Approach Quantifying Habitat Suitability of Cheatgrass (Bromus tectorum) Engineered Habitats for Great Basin Reptiles
… understanding of the impacts of invasion on native wildlife is lacking. Furthermore, the driving mechanisms behind those adverse impacts of invasion that have been quantified are rarely investigated. An understanding of such mechanisms is needed to predict wildlife responses to plant invasion …

Effects of non-native woody plant species on shrubland birds of conservation concern
Shrubland birds are among the fastest declining groups of birds over the past 50 years. Habitat loss and degradation are proposed as being major drivers, but the underlying causes of these declines are unknown. I investigated some of the potential factors driving population declines in three …

Influence of habitat complexity on diversity and community structure of arboreal spiders in grassland-shrub systems
… much of the arboreal habitat is in the form of shrubs, but the role and importance of shrubs in distribution and diversity of arthropods in grasslands is unknown. Spiders are a useful indicator for examining the role of shrubs in arthropod ecology because they are genetically and behaviorally …
