DNA in seawater captures tropical biodiversity

Jun 4, 2020

Accurate, rapid, and comprehensive biodiversity assessments are very important to understand how ecosystems are changing, and what areas of the ocean should be protected. The problem is that most species are very small, difficult to identify and they are very good at hiding. As a result, it has been impossible to quantify biodiversity beyond the most conspicuous species like fish and corals.

However, most species shed DNA in their surrounding environment in the form of feces, mucus, eggs... We call it environmental DNA (eDNA).

eDNA can be collected and sequenced as a way to understand what species are nearby, but very few studies have tested whether it actually work in very diverse tropical ecosystems. We used a single PCR survey of eDNA in seawater using a broad metazoan primer to characterize differences in community composition between five adjacent habitats at 19 sites across the tropical Caribbean bay of Bocas del Toro in Panama. We paired this effort with visual fish surveys to compare methods for a conspicuous taxonomic group. eDNA revealed a tremendous diversity of animals (8,586 operational taxonomic units), including many small taxa that would be undetected in traditional in situ surveys. Fish comprised only 0.07%

of the taxa detected by the broad COI primer, yet included 43 species not observed in the visual survey. eDNA revealed significant differences in fish and invertebrate community composition across adjacent habitats and areas of the bay driven in part by taxa known to be habitat-specialists or tolerant to wave action. Our results demonstrate the ability of broad eDNA surveys to identify biodiversity patterns in the ocean.

corals and coral reefs

Funding: Mark and Rachel Rohr Foundation
RRR: "R" (Rohr) "R" (Reef), "R" (Resilience)

Objectives

The goal of the Rohr Reef Resilience Program is to assess how corals in the genus Pocillopora withstand and recover from environmental changes, specifically those caused by increased greenhouse gas emissions. More specifically, we use controlled experiments and field surveys to:

Determine how Pocillopora corals maintain essential physiological and biochemical processes in the face of thermal stress.

Assess how the response of corals to thermal anomalies differs among coral genotypes, among corals that associate with different clades of algal symbionts and among corals that have experienced different thermal regimes.

Establish a baseline of the natural variability in coral physiological conditions, coral microbiome structure, coral demography, and community composition across Panama and the Tropical Eastern Pacific that will be used to assess the impact of environmental extremes, such as El Niño events, on physiological functions at the individual level, population dynamics, and overall ecosystem structure.

Assess how variations in fish and macroinvertebrate community structure across different sites and regions of the TEP are associated with differences in coral assemblage structure and responses to environmental disturbances.

Quantify seasonal and interannual fluctuations in herbivory and predation rates on benthic organisms to assess how these processes contribute to regional differences in colonization and growth rates of algae and other invertebrates that can potentially adversely affect coral recovery.

Quantifying landscape-level variation in forest structure and dynamics with mobile laser scanning and drone photogrammetry

Helene Muller-Landau, mullerh@si.edu

Barro Colorado Island and/or Gamboa, Panama

Tropical forests vary widely in their structure and dynamics - and thus in their biomass carbon stocks and fluxes - even after controlling for forest age. Forest structure encompasses the horizontal and vertical distribution of vegetation, which is determined by the abundances and spatial arrangement of trees and lianas (woody vines) of different forms and sizes. Forest dynamics encompasses changes over time in this structure due to the growth (or shrinkage) and death of individual trees and lianas.

Traditionally, foresters and ecologists have investigated forest structure and dynamics using forest census plots, in which individual tree stems are mapped, identified to species, and measured in stem diameter. These data have yielded many insights into general patterns of variation in forest structure and dynamics in terms of the abundances of trees of different stem diameter, their diameter growth rates, and their mortality rates. However, these data enable only indirect and approximate estimation of forest biomass carbon stocks and fluxes, because trees vary widely in height and crown form, and thus there is wide variation in tree biomass among trees of a given diameter.

Laser scanning and photogrammetry now enable much more direct measurement of the spatial distribution of vegetation within forests, and thereby provide much more detailed information about forest structure and its change over time. Since 2014, we have been conducting repeat drone flights and photogrammetry to quantify canopy structure and dynamics on the Barro Colorado Island 50 ha plot and other focal sites in central Panama. In 2021, we acquired a handheld mobile laser scanner (Geoslam ZEB Horizon), and began using it to quantify understory forest structure, including the locations, sizes, and detailed 3D form of individual tree and liana trunks and branches. We focus intensive data collection in mapped plots, in which we can relate these data to tagged trees of known species identity. We are also collaborating to link these drone photogrammetry and laser scanning data to satellite remote sensing.

Our objectives are to:

Quantify spatial variation in forest structure and dynamics in central Panama at high spatial and temporal resolution over large areas.

Investigate how spatial variation in forest structure and dynamics relates to abiotic and biotic drivers including soils, climate, topography, stand age, liana abundance, and tree species composition, and how temporal variation in forest dynamics relates to climate variation.

Link laser scanning and drone photogrammetry data to tree census data within mapped plots, to quantify individual tree morphology, crown growth and damage, and mortality, and investigate how these vary with tree species identity, individual tree biotic neighborhood, and site characteristics.

Evaluate how stand-level forest structure and dynamics from laser scanning and drone photogrammetry relate to forest census data and to remote sensing products.

Ultimately, this research seeks to contribute to a mechanistic understanding of variation in tropical forest structure and dynamics that can inform better vegetation models and enable us to accurately predict forest responses to global change.

Mentor Goals and Intern benefits:

Interns will gain experience in tropical forest field research, collection and processing of mobile laser scanning and/or drone photogrammetry data, data analysis in R or Python, reading and discussing scientific literature, and oral presentation of scientific research to the lab group. Interested interns will have the opportunity to contribute to a scientific publication.
