Jim Dines | Whale Mating: In the Hips
A new study turns a long-accepted evolutionary assumption on its head, finding that whale pelvic bones play a key role in mating.

Tropical forests in the Anthropocene - Special Seminar
Please consider attending the following special seminar. It should be an overview from a leading forest ecologist that would appeal to anyone with a general interest in historical and contemporary environmental change (from megafaunal extinctions to climate change).
Tropical forests in the Anthropocene

Abstract: The Anthropocene is characterized as an epoch when human influence has begun to fundamentally alter many aspects of the Earth system, and many of the planet¹s biomes. Here I review and synthesize our understanding of Anthropocene change in tropical forests, in the context of the long-term environmental history of humanity in the tropics from the Pleistocene to the present. I explore possible reactions and responses to change in the tropics. Key facets of Anthropocene change in tropical include deforestation, timber and wood extraction, the loss of fauna that maintain critical ecological connections, the spread of fire, landscape fragmentation and the spread of second-growth forests, invasion and pathogen spread, and increasing CO2 and climate change. The patterns of change are spatially heterogeneous, often have strong interactions among them, can have both large-scale and remote effects and play out through ecological cascades over long time scales. As a consequence, most tropical forests are on a trajectory to becoming altered ecosystems, and many are becoming novel ecosystems. I explore strategies for shaping the transition of tropical forests through the early Anthropocene, as well as highlight opportunities and challenges for the tropical forest science and conservation community.

SPECIAL SEMINAR
Microbialite genetic diversity and N cycling
Luisa I Falcón
Bacterial Ecology Lab., Institute of Ecology, UNAM
Microbialites have
played an important role in the early history of life on Earth with fossilized
forms representing the oldest evidence of life on our planet dating back to
3500 Ma. Extant microbialites have been suggested to be highly productive and
diverse communities with an evident role in the cycling of major elements, and
in contributing to carbonate precipitation. We have analyzed microbial genetic
diversity of microbialites living in different types of environments throughout
Mexico, including desert ponds, coastal lagoons and crater-lakes. Microbialite
communities are very diverse (H′ = 6–7) and show geographic variation in composition, as well as
an environmental effect related to pH and conductivity, which together explain
33% of the genetic variation. N cycle pathways including N2
fixation, nitrification, denitrification and anammox are evident in the
potential community, but only N2 fixation by heterocyst-forming
Cyanobacteria within Nostocales are
actively transcribed. Our studies suggest that N limitation in the environment
strongly favors autotrophy and diazotrophy and restricts remineralization
pathways via denitrification and anammox. Cyanobacteria that form heterocysts
and are actively transcribing for N2 fixation, are fundamental
players in microbialites since they are responsible for providing reduced N
–amides, C in lipids and carbohydrates, and host in their external cell
membranes the main sites of carbonate mineral precipitation.
