A light and electron microscope study of Corylus avellana L.
vegetative buds infested with the eriophyoid mites, Cecidiophyopsis
vermiformis Nal. and Phycoptella avellanae Nal., is reported. Descriptions
are given of changes in infested stipule tissue. The
nipple-like proliferations (enations) which arise on the infested
stipule surface are covered by a...
The widespread fragmentation, channelization, and simplification of river ecosystems has had acute environmental impacts, including degradation of water quality and habitat and biodiversity loss (Vörösmarty et al., 2010). These concerns have incited an increased focus on reestablishing ecological and hydrogeomorphological functions and improving habitat that has been lost in riverine...
Coastal communities throughout the US West Coast and elsewhere are facing the daunting task of preparing for climate change impacts, particularly the hazards from increased flooding and erosion. With sea-level rise, changing storminess patterns, and possible changes to the frequency and severity of major El Niño events, communities are already...
Conventional wastewater treatment facilities using activated sludge, secondary clarifiers, and chlorine disinfection comprise a large portion of urban wastewater treatment practices in the United States. While highly adept at removing chemical, physical, and numerous biological contaminants, these treatment methods are ineffective at removing contaminants of emerging concern, such as antibiotics...
The purpose of this study was to examine the general nature of attributions of Chinese parents in the U.S. regarding their preschool children's social behaviors. Eighty-seven parents with preschool children participated. The attributions were examined along three causal dimensions: locus of causality (internal versus external), stability (stable versus unstable), and...
This study investigated the prevalence of misgendering and its impact on stigma and mental health outcomes in college students. Two hundred and eighty-five students participated in a comprehensive survey, providing insights into the frequency of misgendering they experienced, the level of stigma they felt in response, as well as their...
Adolescent pregnancy is a serious problem which creates social and
emotional consequences for 1 in 10 teenaged girls and their families.
Although the severity of the problem has been well documented in the
literature, few empirical investigations have been conducted to expand
information or to aid in the understanding of...
Dairy leuconostocs are frequently used as aroma-producing bacteria in mesophilic cultures used as starters for milk fermentations. Sixty Leuconostoc strains from different culture collections were studied taxonomically for species identification. Based on morphological, physiological and biochemical tests, twenty of these strains were typed as Leuconostoc mesenteroides ssp. cremoris (Leu. cremoris)....
Francisella tularensis is a gram-negative facultative intracellular
coccobacillus that primarily infects macrophages. The causative agent of tularemia,
this bacterium is considered among the most infectious organisms known, requiring
fewer than ten organisms to cause disease. Although ubiquitous in nature,
transmission to humans is rare but can occur via insect bites,...
