Ecological Genetics Of Adaptive Life-history Phenotypes In The Cricket Allonemobius socius
(Biology, 2009-09-16)As many organisms inhabit unstable environments, the ability to respond to changing environmental conditions is highly adaptive, and results in the evolution of phenotypic plasticity. Thus, identifying the genetic basis ... -
Ecomorphology Of The Mexican Fence Lizards Of The Sceloporus Formosus Group (Squamata: Phrynosomatidae)
(Biology, 2009-09-16)A central belief of ecomorphological studies is the link between morphology and performance, but, surprisingly few analyses demonstrate this relationship. Fence lizards of the genus Sceloporus offer a useful system for ... -
EFFECTS OF A N2-FIXING BIOFERTILIZER ON THE RHIZOSPHERE MICROBIOME AND THE INFLUENCE OF BIOCHAR ON SOIL FERTILITY AND MICROBIAL COMMUNITIES
(2021-12-20)The rhizosphere microbiota and endosymbionts are the major contributors to biogeochemical cycling and significantly impact the associated host plant. Their association with plant roots is inevitable for plant health and ... -
The Effects Of An Artifically Elevated Thermal Environment And Seasonal Acclimatization On The Thermal Tolerance Of The Western Mosquitofish, Gambusia affinis
(Biology, 2008-09-17)Gambusia affinis, the western mosquitofish, is a very hardy, live-bearing fish that has invaded freshwater habitats worldwide. The success of the western mosquitofishs' invasion is due to its reproductive capabilities and ... -
The Effects Of Mine Land Reclamation Of Herpetofaunal Communities
(Biology, 2012-07-25)Succession describes the process of community change over time after a disturbance. Understanding these processes allows ecological restoration projects to take advantage of natural community trajectories. Reclamation ... -
Effects Of Nutrient Limitation, Competitors And Grazers On The Abundance And Toxicity Of Laboratory Cultures Of P. parvum, a Harmful Alga
(Biology, 2008-08-08)P. parvum Carter is a haptophyte that occurs world wide in both fresh and brackish waters. Though P. parvum blooms occur world wide under a variety of environmental conditions, it occurs during the cooler months of the ... -
EFFECTS OF pH SHOCK AND HEAT STRESS ON THE GROWTH OF NITROGEN-FIXING BACTERIA AND THEIR PHOSPHATE SOLUBILIZATION
(2021-05-11)Rhizobia are well known for their ability to fix atmospheric nitrogen (N) into ammonia, so called biological nitrogen fixation (BNF), either as free-living bacteria in soil or as symbiotic partners of legume plants. ... -
Effects Of The Exotic Invader, Tamarix spp., On Aspects Of The Aquatic Ecosystem At McComb Creek, Presidio County, Texas
(Biology, 2010-07-19)The effects of saltcedar, Tamarix spp., invasion in riparian zones of the western United States have been well documented. These include, but are not limited to soil salinization, and shifts in hydrology and water use. ... -
EFFICACY OF A SERIES OF ORGANOMETALLIC POLYMERS AS ANTI-CANCER AND ANTIVIRAL AGENTS
(2017-08-18)Organometallic compounds, particularly organotin compounds, have been known to possess biological activity for over 80 years. A variety of these compounds have demonstrated antimicrobial, anti-cancer, and antiviral activities. ... -
Efficacy Of A Series Of Organotin Polymers As Anticancer And Antiviral Drugs
(Biology, 2008-04-22)Anticancer drugs have been shown to have antiviral abilities as well. The two types of diseases are similar in that they hold the cell in a continued growth phase. Therefore, if a drug has anticancer activity, it could ... -
Efficacy Of Selected Natural And Synthetic Novel Organic Compounds In Prevention Of Zebra Mussel (Dreissena Polymorpha) Macrofouling By Byssal Attachment Inhibition
(Biology, 2007-10-08)The invasive, freshwater, bivalve, Dreissena polymorpha (zebra mussel) was introduced to North America in the Great lakes in 1986 and has since spread throughout the waterway of the eastern and central United States and ... -
The Eggshell Structures Of Ringed Turtle - Doves (Streptopelia risoria)
(Biology, 2007-08-23)The avian egg provides nutrients and protects the growing embryo from physical and microbial harm. Structures fundamental to the protection are the membrane layers, which are tightly meshed networks of collagen fibers, ... -
Element Stoichiometry Of Ochromonas danica As A Function Of Growth Rate And Temperature
(Biology, 2010-03-03)The microbial loop stresses the importance of flagellated protozoa as predators of bacteria and regenerators of nutrients, the outcome of which affects higher trophic levels. The element stoichiometry of flagellates has ... -
ELUCIDATING THE EVOLUTION OF SEX CHROMOSOME DOSAGE COMPENSATION USING BEETLES
(2021-05-04)Sex chromosomes are unique because of their role in sex determination. More importantly, sex chromosomes spend an unequal amount of time between the sexes which has significant consequences since it provides an opportunity ... -
ELUCIDATING THE MOLECULAR GENETIC BASIS OF BEHAVIORS RELATED TO THE LOSER EFFECT
(2022-09-01)Across the animal kingdom, when individuals experience social defeat (losing an aggressive conflict with a conspecific), it elicits stereotypical loser behavior such as isolation or submissiveness. In many species, social ... -
ENDOPHYTIC BACTERIA ISOLATED FROM AESCHYNOMENE INDICA PLANTS AND THEIR ROLE IN NOD-FACTOR INDEPENDENT NODULE FORMATION AND NITROGEN FIXATION
(2023-05-19)The formation of specialized root organs known as nodules is the most defining characteristic of leguminous plants due to the fixation of atmospheric nitrogen to bioavailable forms enabled by rhizobial endosymbionts. This ... -
