The understanding of marine ecosystems requires long-term historical data. Unfortunately, population dynamics data of marine species are much like Hobbes' view of the life of primitive humans: nasty, ...
Human health and wellbeing are closely linked to the health and resilience of ecosystems. When natural disasters occur in situations where natural resources have been severely degraded, it is much mor...
Cold-seep communities associated with brine and hydrocarbon seepage on the upper Louisiana slope (ULS) of the Gulf of Mexico (GoM) were among the first discovered (Kennicutt et al., 1985), and they ha...
Far from being selfish organisms whose sole purpose is to maximize their own reproduction, bacteria in large communities work for the greater good by resolving a social conflict among individuals to e...
Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and subsequent sub-cloning and sequencing were used in this study to analyze the molecular phylogenetic diversity and spat...
This study characterized the fecal bacterial community structure and inter-individual variation in 30-week-old Duroc pigs, which are known for their excellent meat quality. Pyrosequencing of the V1–V3...
Water, in all its dimensions and scope, concerns humans as civilization, individuals and communities immersed in an environment that faces serious environmental threats and changes. The efficient wa...
Coastal communities in 15 states that depend on the $1 billion shelled mollusk industry (primarily oysters and clams) are at long-term economic risk from the increasing threat of ocean acidification, ...
Once the lightest fractions of the oil had been consumed, the organisms that had been digesting those compounds declined, replaced by others able to chew up the remaining heavier materials. Ultimately...
We present research aimed at determining how bacteria associated with aquatic plants influence phytoextraction of heavy metals. We focused on the aquatic plant Lemna minor and its response to cadmium ...
We present research aimed at determining the role of soil structure in the organization of microbial communities in soil. We have focused on the microbial communities involved in functional roles with...
Soil and herbivore gut environments present different challenges to plant degrading bacteria in terms of nutrient availability, fluctuations in moisture, pH and temperature, and temporal constraints, ...
Climate change may alter the spatial distribution, composition, structure and functions of plant communities. Transitional zones between biomes, or ecotones, are particularly sensitive to climate chan...
Climatic change threatens biodiversity worldwide. In the forests of the northeastern United States, climate change is expected to increase mean annual temperatures by up to 4.5˚C and change preci...
Urbanization, as it transforms natural biotic systems into human-dominated landscapes, is recognized as one of the greatest threats to biodiversity throughout the world. Furthermore, urban dwellers ar...
