High proportion of smaller ranged hummingbird species coincides with ecological specialization across the Americas.
(2016-02-10)
Ecological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with ...

Loss of SOX10 function contributes to the phenotype of human Merlin-null schwannoma cells.
(2013-02)
Loss of the Merlin tumour suppressor causes abnormal de-differentiation and proliferation of Schwann cells and formation of schwannoma tumours in patients with neurofibromatosis type 2. Within the mature peripheral nerve ...
Distinct phenotypes of three-repeat and four-repeat human tau in a transgenic model of tauopathy.
(2017-09)
Tau exists as six closely related protein isoforms in the adult human brain. These are generated from alternative splicing of a single mRNA transcript and they differ in the absence or presence of two N-terminal and three ...
Neutralizing antibodies and pathogenesis of hepatitis C virus infection.
(2012-10-09)
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease worldwide. The interplay between the virus and host innate and adaptive immune responses determines the outcome of infection. There is increasing ...
Disruption of microtubule integrity initiates mitosis during CNS repair.
(2012-08-14)
Mechanisms of CNS repair have vital medical implications. We show that traumatic injury to the ventral midline of the embryonic Drosophila CNS activates cell divisions to replace lost cells. A pilot screen analyzing ...
Drosophila embryos as model to assess cellular and developmental toxicity of multi-walled carbon nanotubes (MWCNT) in living organisms.
(2014)
Different toxicity tests for carbon nanotubes (CNT) have been developed to assess their impact on human health and on aquatic and terrestrial animal and plant life. We present a new model, the fruit fly Drosophila embryo ...
Effects of naturally acidified seawater on seagrass calcareous epibionts.
(2008-12-23)
Surface ocean pH is likely to decrease by up to 0.4 units by 2100 due to the uptake of anthropogenic CO2 from the atmosphere. Short-term experiments have revealed that this degree of seawater acidification can alter ...
Predicting ecosystem shifts requires new approaches that integrate the effects of climate change across entire systems.
(2012-04-23)
Most studies that forecast the ecological consequences of climate change target a single species and a single life stage. Depending on climatic impacts on other life stages and on interacting species, however, the results ...
