Data from: A geographic test of species selection using planktonic foraminifera during the Cretaceous/Paleogene mass extinction
Species selection has received a great deal of theoretical attention but it has rarely been empirically tested. It is important to determine the level of selection that operated during a particular extinction event because it can help distinguish between traits that were actually responsible for extinction and those that were merely correlated with it. Here, we present a test that can help distinguish between organismal and species-level selection, which we demonstrate using the high-resolution fossil record of planktonic foraminifera species recorded in deep-sea sediment cores. Our test examines the fate of survivors and victims during the Cretaceous/Paleogene (K/Pg) mass extinction within single geographic regions, where all individuals experience the same selection pressures. Selection at the organismal level implies that individual members of surviving species are more fit than those of victimized species, and therefore should be more likely to survive in affected areas; conversely, selection at the species level implies individuals will suffer equally within an affected area. We find that survivors of the mass extinction suffered very high extirpation rates in cores where the overall extinction rate was high, indicating that individual members of the surviving species were generally no more fit than individual members of extinct species. Rather, these species were able to survive because they possessed advantageous species-level traits, such as larger geographic ranges and greater abundances than victimized species. This geographic pattern of extirpation suggests that selection operated at the species, rather than organismal, level during the K/Pg mass extinction of planktonic foraminifera.
Data from: A morphospace of planktonic marine diatoms, parts I and II
NOTE: PLEASE ALSO SEE Kotrc B, Knoll AH (2015) A morphospace of planktonic marine diatoms. II. Sampling standardization and spatial disparity partitioning. Paleobiology 41(1): 68-88. http://dx.doi.org/10.1017/pab.2014.5. Both molecular clocks and the first appearances of major groups in the fossil record suggest that most of the range of diatom morphologies observed today had evolved by the end of the Cretaceous Period. Despite this, a canonical reading of the Cenozoic fossil record suggests a dramatic rise in taxonomic diversity that can be interpreted as an explosion of morphological variety. We investigated this apparent discrepancy by using a discrete-character-based, empirical diatom morphospace, resolved by molecular phylogeny and by fossil occurrences through time. The morphospace shows little correspondence to phylogeny and little Cenozoic change in disparity as measured by mean pairwise distance. There is, however, an increase in the total volume of morphospace occupied. Although the increase in occupied volume through time ostensibly supports a conclusion of increasing morphological variety, sampling biases and other data suggest an underlying stationary pattern more consistent with molecular clock data.
Diversity-stability cascade in pond plankton experiments
<p>This collection of files consists of freshwater plankton biomass data from a laboratory microcosm experiment and an accompanying field mesocosm experiment in which we manipulated the presence of two heteropteran predators. In the laboratory experiment, we incubated 20 large microcosms with phytoplankton and zooplankton, fully crossing a 1x vs. 2x zooplankton density treatment with presence or absence of a single <em>Notonecta undulata </em>adult. Two of these microcosms were lost, resulting in data for 18 of these large microcosms. Concurrently, we incubated 20 small microcosms with a smaller amount of the same plankton mix, which similarly were fully crossed with the 1x vs. 2x zooplankton density treatment and presence or absence of a single <em>Neoplea striola </em>adult. After five days we collected the zooplankton remaining in each microcosm for identification and biomass estimation. For the field experiment, we established 20 mesocosms (cattle tanks) with phytoplankton and zooplankton collected from the same sources, and added six <em>Notonecta </em>adults to five mesocosms, 90 <em>Neoplea </em>adults<em> </em>to another five, and three <em>Notonecta </em>and 45 <em>Neoplea </em>to another five, with the remaining five mesocosms acting as no-predator controls. We sampled both the phytoplankton and zooplankton once per week for six weeks for identification and biomass estimation.</p>
