Assessing the role of cladogenesis in macroevolution by integrating fossil and molecular evidence

Mar. 14, 2013 by

New species evolve via two mechanisms, cladogenesis and anagenesis. Cladogenesis represents the subdivision of a species into two, reproductively isolated, independently evolving forms; whereas anagenesis represent within species evolution. In a study published in PNAS we identify the extent to

Means conceal the focus of climate change biology

Feb. 13, 2013 by

Biologists have all read papers or sat through seminars about the biological consequences of climate change and seen a figure like the one here (without the dots). A traditional variance-style test and standard error bars show that a climate change

Making people care about climate change. Bill Moyers interview with Yale Professor, Anthony Leiserowitz (January 4 2013):

Calcification, Storm Damage and Population Resilience under Climate Change

Oct. 30, 2012 by

In a study published in PLOS ONE, we explore two facets of climate change expected to detrimentally affect reef-building organisms by increasing their mortality rates and decreasing their calcification rates: increased tropical storm intensity and ocean acidification. We find that

Biomechanics of coral reef substrate and implications for coral colony integrity

Sep. 23, 2012 by

The physical structure of coral reefs plays a critical role as a barrier to storm waves and tsunamis and as a habitat for living reef-building and reef-associated organisms. However, the mechanical properties of reef substrate (i.e. the non-living benthos) are

Coral reefs migrate south for the future

Jul. 5, 2012 by

Coral reef scientists have discovered four new tropical coral species not previously reported growing in southern locations. Published in the journal Coral Reefs, researchers say the discovery is part of a larger trend in reef-building corals moving southward along the
