Caro Lab

Overview I conduct basic and applied biological research principally in Africa. I split my time between UC Davis, Dar es Salaam, Pemba Island and Katavi National Park in Tanzania.

Conservation biology Broad scale analyses: I am interested in anthropogenic pressures on protected areas (Caro et al. 2014a), in documenting the whereabouts of remaining wildlife corridors on mainland Tanzania (Caro et al 2009); and implementation of conservation strategies in that country (Caro & Davenport 2015). Fieldwork: On Pemba, I am collaborating with Monique Borgerhoff Mulder on the efficacy of different ways to conserve remaining forest patches.  I work with Amy Collins on Pemba forest health, and with Jay Riggio on corridors in Tanzania. I have explored how umbrella, indicator and flagship concepts may be useful in conservation (Caro 2010). http://islandpress.org/ip/books/book/islandpress/C/bo8009659.html).

Evolution of coloration in mammals Broad scale analyses: My basic research investigates the function and evolution of coloration in mammals (Caro 2005a; 2009) using comparative phylogenetic analyses (e.g., Caro et al. 2011). Fieldwork: I use detailed field observations and simple experiments to understand why zebras have black and white stripes (Caro et al. 2014b; Caro & Stankowich 2015), and I am working on coconut crab coloration on Pemba.

Adaptive significance of antipredator defenses I collaborate with Ted Stankowich on phylogenetic comparative analyses of defenses (e.g., Stankowich & Caro 2009; Stankowich et al. 2011) and currently on intraspecific variation in aposematism. I have written a monograph “Antipredator Defenses in Birds and Mammals” (Caro 2005b).

Interspecific competition in carnivores I examine the role that carnivores play in affecting the ecology and evolution of other carnivores employing comparative continental-wide analyses (Hunter & Caro 2008; Stankowich et al. 2014).

Animal behavior and conservation biology I try to uncover linkages between animal behavior and conservation but have found them to be weak (Caro & Riggio 2014). Nonetheless, many students are keen to apply insights from animal behavior saving species but do not know how to proceed. We have outlined ways to link these disciplines effectively (Caro & Sherman 2011).

Development work in Tanzania Working with Tanzanians and Monique Borgerhoff Mulder, we have raised money for a Youth Center in the western part of the country and are trying to get Tanzanian students into national parks (http://mpimbweproject.com/). Periodically I give advice to the Tanzanian Government about wildlife policy.

I am interested in taking on very committed graduate students, especially minorities and foreigners, and in working with postdocs remotely and at UC Davis.
