Manganese is an essential trace metal, but excessive exposure causes neurotoxicity, including parkinsonian syndromes, cognitive deficits, and may contribute to neurodegenerative diseases.

AbstractUnderstanding general principles about the origin of species remains one of the foundational challenges in evolutionary biology. The genomic divergence between groups of individuals can spawn hybrid inviability and hybrid sterility, which presents a tantalizing developmental problem.

Investigating the molecular basis of adaptation and speciation in divergent populations [PDF]
The creation of biodiversity involves the evolution of new species. Recent trends in the study of speciation have increased the emphasis on the role of ecology in adaptation and the evolution of reproductive isolation.

Electroactive speciation studies for metal ion sensing [PDF]
Chemical speciation is an important factor in understanding the role of metals in the environment. Bioavailability of trace metals is influenced by the degree of the labile fraction of the metal that is readily available for interaction with a cell ...

Solid-phase phosphorus speciation in Saharan Bodélé depression dusts and source sediments [PDF]
Phosphorus (P) is one of the most important limiting nutrients for the growth of oceanic phytoplankton and terrestrial ecosystems, which in turn contributes to CO2 sequestration. The solid-phase speciation of P will influence its solubility and hence its

Speciation and endemism under the model of island biogeography [PDF]
: Speciation has been considered as a primary process contributing to species diversity, but its contribution to the diversity of local communities has not been fully appreciated. Based on the theory of classic island biogeography, we derived a model for

The geography of speciation is one of the most contentious topics at the frontier between ecology and evolution. Here, building on previous hypotheses, I propose that ecological constraints on species co-existence mediate the likelihood of speciation ...

Adaptive speciation: Epilogue [PDF]
Unraveling the origin of biodiversity is fundamental for understanding our biosphere. This book clarifies how adaptive processes, rather than geographic isolation, can cause speciation.

Predictability, an Orrery, and a Speciation Machine: Quest for a Standard Model of Speciation. [PDF]
Accurate predictions are commonly taken as a hallmark of strong scientific understanding. Yet, we do not seem capable today of making many accurate predictions about biological speciation. Why?
