ESTIMATING THE ORGANIC CARBON CONTENT OF PHYTOPLANKTON FROM CELL VOLUME OR PLASMA VOLUME1
Equations for estimating the organic carbon in phytoplankton from cell volume or plasma volume are derived from original data on five species of diatoms and from data in the literature. Differences…

The Evolution of Multicellularity: A Minor Major Transition?
TLDR
Benefits of increased size and functional specialization of cells have repeatedly promoted the evolution of multicellular organisms from unicellular ancestors, but these benefits may be opposed by genetic conflicts that arise when mutant cell lineages promote their own increase at the expense of the integrity of the multice cellular organism.

Feeding and Nonfeeding Larval Development and Life-History Evolution in Marine Invertebrates
TLDR
Many marine invertebrates have elaborate feeding larval forms whereas others, sometimes within the same taxon, have more direct development, and questions about the evolution and consequences of the life histories of these forms are raised.

TLDR
A survey of larvae in spiralian phyla indicates that for several reasons the spiralians have been more flexible in acquiring new planktotrophic larval forms, and some of the reasons for these differences are indicated.

Functional Consequences of Phenotypic Plasticity in Echinoid Larvae.
TLDR
It is shown that larvae of a sand dollar can capture suspended food particles at the tips of longer arms, and that longer ciliated bands result in higher maximum clearance rates.

HETEROCHRONIC DEVELOPMENTAL PLASTICITY IN LARVAL SEA URCHINS AND ITS IMPLICATIONS FOR EVOLUTION OF NONFEEDING LARVAE
TLDR
Sea urchin larvae exposed to different amounts of food in the laboratory and in the field produced differences in timing of development of larval and juvenile structures, which suggests that developmental plasticity that is adaptive for feeding larvae also contributes to correlated and adaptive evolutionary changes in the transition to nonfeeding larval development.

Evolution of local recruitment and its consequences for marine populations
Advantages of dispersal on the scales that are possible in a long pelagic larval period are not apparent, even for benthic species. An alternative hypothesis is that wide dispersal may be an…
Oxygen Supply and Limits on Aggregation of Embryos
TLDR
Embryos of opisthobranchs that are Normally aggregated and embryos of sea urchins that are normally dispersed were similarly tolerant of low oxygen concentrations and low pH, which indicates tolerance of hypoxia and accumulating wastes.

EFFECTS OF MATERNAL AND LARVAL NUTRITION ON GROWTH AND FORM OF PLANKTOTROPHIC LARVAE
TLDR
Effects of maternal habitat, gonad size, and egg size on larval growth rate were significant but small compared to the effect of abundance of larval food, and larval form can be used as an index of planktonic conditions affecting feeding larvae.
