University of Guam Everyone needs to eat. But it's a dog-eat-dog world, and with the exception of the top predators, everyone also gets eaten. To cope with this vicious reality, a tiny insect that eats plants has learned to employ the plant's hairs for physical protection from its beetle predator. The pest is called the cycad aulacaspis scale, and its invasion into numerous countries in recent years has caused immeasurable loss of biodiversity. Cycads belong to an ancient lineage of...

Primary succession on the slopes University of Guam ecologist Thomas Marler recently mobilized efforts to characterize the vegetation that has recovered following the eruption of Mount Pinatubo, Philippines. "My interest was sparked by the paradox that this volcano's cataclysmic 1991 eruption was so powerful it changed global climate, yet after a full 15 years the biology of the recovering ecosystem had not been studied," said Marler. The void of research motivated the Guam ecologist to spend...

Researchers look for small control organism "The small size of an alien insect that feeds on a native tree from the western Pacific island of Guam allows it to hide in cracks and other locations that are out of reach for its only local natural enemy," said UOG entomologist Aubrey Moore. Moore has teamed up with UOG ecologist Thomas Marler to study the relationship between the native cycad tree, known as "fadang" in the Chamorro language, and a minute alien insect pest called cycad aulacaspis...

Moth also triggers the plants into increased frequency of reproduction When a plant endemic to several islands in the Western Pacific Ocean taps the services of a helpful insect, a double-dose of benefits comes its way. The plant is a member of a unique group of plants known as cycads, which produce their seeds in cones rather than within fruits. The insect is a tiny moth currently known to exist only on the islands of Guam and Rota. The insect's primary role is to ensure seed production...

Respecting the Complexity of Cultural Differences in Horticulture Instruction University classrooms around the world are becoming more like the highly diverse classrooms that prevail at the University of Guam. This trend has led UOG professors Thomas Marler and Seyda Turk-Smith to coauthor a journal article covering some of the unique features of teaching to a group of learners with a range of cultural value systems. "Dr. Marler is a horticulture educator, and learning more about how my...

Thomas Marler recently published the results of his research that reveal some of the attributes of the long-lived leaves of Guam's Cycas micronesica plants. "These leaves are relatively large and are constructed of tough tissues," said Marler. "Both of these factors indicate the construction costs of this leaf form are substantial."Green leaves must pay back their own construction costs, but each leaf is also required to supply the energy needed to maintain its live tissues throughout its...
