Vicente Luis Jiménez Ontiveros

Research technician

I work as a research technician with the scientific researcher David Alonso. I study the temporal dynamics of ecological communities, asking how stochasticity, dispersal, and species interactions shape biodiversity through time. At CEAB-CSIC, I work at the interface of theoretical and applied ecology, developing analytical and computational frameworks that link ecological theory with long-term empirical time series, especially in metacommunities and microbial systems.

My research spans diverse ecosystems -from inland saline and high-mountain lakes to airborne and vineyard soil microbiomes and marine fish metacommunities- using time-series analyses, network approaches, and null models to disentangle stochastic versus deterministic drivers of community structure and beta-diversity.

I developed the R package island to estimate colonization and extinction rates from community time series, extending island biogeography and metacommunity theory with data-driven stochastic tools. I also developed metrics to compare how fast composition changes across ecosystems, and I explore how environmental stressors reshape diversity and interaction networks. Recently, I have applied generalized Lotka-Volterra models to estimate trait dimensionality in ecological communities.
