Field ecology studies on migratory locust

submitted by: UP Los Baños
A report done on the project conducted to (1) study the biometrics and morphology of solitary and gregarious locust individuals of both sexes, (2) observe and measure rates of development of different life stages of locust in the field, (3) investigate the possible environmental and other factors that influence population development and shift from solitary to migratory phases, (4) study the ecology of breeding sites of locust, and (5) observe and understand the aggregation process, swarm...

Evolution of Reproductive Morphology in Leaf Endophytes

submitted by: JeffreyTownsend
The endophytic lifestyle has played an important role in the evolution of the morphology of reproductive structures (body) in one of the most problematic groups in fungal classification, the Leotiomycetes (Ascomycota). Mapping fungal morphologies to two groups in the Leiotiomycetes, the Rhytismatales and Hemiphacidiaceae reveals significant divergence in body size, shape and complexity. Mapping ecological roles to these taxa reveals that the groups include endophytic fungi living on leaves...

Ichnology for the 21st Century: Understanding the differences between continental and marine trace fossils, with implications to the diversity, distribution, and evolution of soil biota ; Department of Geological Sciences, San Diego State University, Seminar Series ; The study of ichnology has come a long way since its inception and it continues to evolve. In particular, progress is being made in understanding the implications of trace fossils in the continental realm and how they can be...
