Pablo Munguia's web page |
Welcome to my home page. I am a graduate student at Florida
State University in the Biological Sciences program (Ecology
and Evolution). I started in 2000, and you would think I have a
dissertation project by now..
I am interested in community ecology, I have worked in projects ranging from fungi to cacti to birds, however my passion lies in benthic systems. I am interested in how interactions among individuals can influence the community-level patterns observed in nature such as migration and extinction, creating a network among communities. My mentors are Tom Miller and Don Levitan. Thanks to them, a lot of stories and adventures arise every day. Email me at: munguia@bio.fsu.edu

During early summer of 2001, craving for a system to study, I stumbled on the
pen shells of St. Joe Bay, Florida. Pen shells (Atrina rigida) are
large bivalves that live embedded in the sand among sea grass. I designed an
experiment to start testing within-community dynamics and their influence on
other communities as well as to figure out the natural history of the system.
Here is the abstract of my talk for the 2002 Benthic Ecology Meeting:
Pen shell community patterns and assemblage: local and regional dynamics.
The interaction between local and regional diversity
patterns has been a major focal point in ecology. Theory predicts one of
two outcomes: (1) diversity at the local scale is a constant proportion of
diversity at a regional scale. (2) Local diversity saturates at higher regional
richness. The second outcome has been difficult to observe in nature due
to three main reasons: problems in delimiting a species pool, pseudoreplication,
and assuming that communities are at some equilibrium. Here I incorporate
the relative abundance of species and assembly time to show how the relationship
between local and regional diversity develops during different colonization
times. At St. Joe Bay, Florida, the pen shell (Atrina sp.) is one of the
few sources of hard substrate, serving as a habitat for sessile and mobile
invertebrates and fish. During the summer of 2001 I placed empty pen
shells spread among different plots within the bay and removed them at different
time intervals. The results showed that with time, species
richness increases significantly while evenness indices saturate.
Initially a local-regional plot of species richness shows that few species are
present at the local scale, regardless of the species pool size. With time
the slope between local and regional richness increases, presenting unsaturated
communities. Rarefying the number of species at the local scale and
comparing them to the regional species pool shows a different pattern.
With rarefied richness there is a positive linear relationship between local and
regional richness initially, but at subsequent times the curve saturates.
These results suggest two things: (1) the degree of species saturation
will depend on the colonization stage of a community. (2) Incorporating species
abundances (i.e. through rarefaction or other techniques) demonstrates the role
of species commonness or rarity in determining patterns of community diversity
at different scales.
