Heaney conducted a comprehensive survey of Luzon mammals. It is solely found in the Philippines, except in the province of Palawan, the Sulu archipelago, and the Batanes and Babuyan group of islands. They are covered in soft, thick pelage that is darker on the back and somewhat white with a moderate orange yellow wash on the ventral front area.
My research is generally question rather than taxon oriented, so grad students in my lab group are encouraged to develop independent research programs that may involve, for example, phylogenetics, biogeography, morphological evolution, or comparative quantitative genetics.
While my taxonomic expertise is with muroid rodents, particularly the South American sigmodontines, past and present students have worked on carnivores, marsupials, frogs, salamanders, plants, cnidarians, and bivalves. Currently, grant support is available for several years for a grad student working on the diversification of muroid rodents.
My research attempts to bridge the micro- and macroevolutionary scales and apply process based models to understand and explain large-scale patterns.
To address this long term goal, my research program involves studying highly diversified groups of mammals at a range of hierarchical levels. Currently, my focus is on molecular phylogenetics and Philippine mice genetics.
The techniques include phylogenetic analyses of morphological and DNA sequence data, comparative analyses of multivariate patterns of covariation, developing the comparative tools to test these multivariate patterns, analysis of geographic variation, and alpha level systematics of living and fossil material.

Graduate Student Research Kenny Wray: Jim Cooper MS ; now a post-doc at Syracuse: Brian Storz MSnow Asst. MS phylogeography of Phyllotis. The primary focus of current research in my lab is molecular systematics of various diverse rodent groups.
These include the Muroidea mice, rates, hamsters, and relativessubfamily Sigmodontinae Neotropical mice and ratsSciuridae squirrelsand several genera within these groups, such as Apomys, Marmota, and Phyllotis. These phylogenies then form the framework for several comparative studies of quantitative genetics, vertebral evolution, and biogeography.
We are also developing a new project in bivalves.
Partly in collaboration with Ron Adkins at the Univ. Tennessee, Memphis, we are conducting a large sequencing effort to resolve one of the most intractable problems in mammals by dense taxon sampling, a large amount of slowly evolving sequence data, and developing new genes for mammalian phylogenetics.
We are curently expanding our species phylogeny to species. We will be using these phylogenies to understand morphological dental and cranial shape diversification, biogeography, and the tempo of diversification. See publication page for some Results Bivalves in Time and Space: We are developing bivalves as a model system for macroevolutionary studies in conjunction with Dave Jablonski Univ.
Collectively, we are producing a combined molecular and morphological phylogeny of extant and many extinct species to test methods of ancestral state reconstruction, molecular clock dating, and biogeographic reconstruction, and models of spatial diversification.

In collaboration with Angel Spotorno and Laura Walker Universidad de Chile and Oswaldo Ramirez Universidad de Heredia Cayetano, Lima I am conducting phylogenetic analyses of multiple mitochondrial and nuclear genes for the Phyllotis darwini species group.
Detailed population level sampling is testing species limits and biogeographic hypotheses, particular the role of the Andes on speciation patterns. Controlled breeding programs in four species will be used to estimate genetic variance-covariance G matrices to examine how G matrices evolve.
These G matrices in turn will calibrate phenotypic covariance matrices from over 30 populations. Phylogeny and historical biogeography in Apomys. Apomys is an endemic Philippine forest mouse Murinae that has diversified on the many islands of the Philippines. In collaboration with Larry Heaney Field Museum of Natural History we are producing a molecular phylogeny for the genus using cyt b Steppan et al.
We are then using the phylogeny to test models of historical biogeography based on Pleistocene sea level fluctuations. Constraints on the evolution of the vertebral column in rodents. I am studying the role of developmental constraints on the evolution of the vertebral column of rodents, focusing on the tail.
Many comparative studies of developmental constraints, adaptation, key innovations, and the like, are hampered by a lack of statistical power stemming from the relatively small number of data points.
I am focusing on the tail of speciose mammalian groups to maximize the sampling of morphological transitions during evolution. The key questions are whether there is a bias shaping the evolution of the vertebral column and if one component of morphology appears favored due to genetic or developmental biases.
To provide the framework or the comparative analyses, I have composited a phylogeny for over species of myomorph rodents from published phylogenies and mapped vertebral characters onto it.

MANILA, Philippines – The Board of Investments (BOI) is teaming up with the Department of Tourism (DOT) and the Philippine Association of Convention/Exhibition Organizers and Suppliers Inc.
(PACEOS) to craft a roadmap for the Meetings, Incentives, Conventions and Exhibitions (MICE) industry. In mice experimentally infected with a Philippine strain of grupobittia.comcum, the drug administered as a single oral dose at the level of 20mg/kg, produced a complete parasitological cure.
More than a 95% reduction in adult worms was obtained when treated with a single oral dose as low as 5mg/kg. Any serious gamer will have to admit that living on an OEM mouse just ain’t gonna cut it. Serious FPS, RPG, and even MOBA players really pay top dollar for more ergonomic, functional, and attractive-looking mice, which have multi-mapping support, last long, and have almost instantaneous clicking response for all those precise clicking input.
