“…The ability of bivalve larvae to prolong the planktonic period and delay settlement and metamorphosis is well documented in the marine literature (e.g., Bayne 1965;Pechenik 1985) and has also been suggested for Dreissena polymorpha (Sprung 1989;Haag and Garton 1992). Long planktonic periods or delay of metamorphosis result in greater sizes at settlement, hence a positive correlation between PII size and time spent in the plankton (Bayne 1965;Lutz and Jablonski 1978).…”

“…Previous studies have documented that bivalve larval size at settlement and metamorphosis as well as the duration of the planktonic period can vary greatly (Bayne 1965;Pechenik 1984Pechenik , 1985. This can be observed in the larval shell of bivalves with planktotrophic larval development, which acts as a skeletal record of the growth and developmental history (e.g., size at settlement and metamorphosis) of the animal (Ockelmann 1965;Lutz and Jablonski 1978;Lutz et al 1984;Martel et al 1995).…”

Abstract-Recently settled postlarval quagga mussels (Dreissena bugensis) and zebra mussels (D. polymorpha) were examined using optic microscopy to determine planktonic shell growth and size at settlement and metamorphosis from two habitats in Eastern Lake Erie: nearshore epilimnion and offshore hypolimnion. Postlarvae (shell length ϳ400-2000 m) were collected from various substrates between 1992 and 1995. Planktonic shell growth and size at settlement and metamorphosis were determined by measuring height of the prodissoconch I (PI) and prodissoconch II (PII) on right valves. Mean PI height was 79.07 (SD ϭ 4.64) and 79.62 m (SD ϭ 4.28) for the quagga and zebra mussel, respectively, and did not differ between species or across habitats. There was, however, a distinct between-species difference in size at settlement and metamorphosis (PII size), with larvae of the quagga mussel settling at significantly larger sizes than those of the zebra mussel (nearshore/epilimnion data: quagga PII means, 256-284 m; zebra PII means, 236-249 m). In addition, quagga mussel larvae settled at a greater size in the offshore hypolimnion habitat (PII mean ϭ 313.64 m, SD ϭ 24.69, n ϭ 320) compared to nearshore epilimnion habitat (mean ϭ 261.89 m, SD ϭ 19.41, n ϭ 207). The additional 28% of larval shell (PII) secreted by offshore hypolimnion quagga mussels may be linked to several factors, including a prolonged planktonic period. This study is the first to document the relationship between offshore distance and size at settlement in a bivalve.

“…Marine invertebrate larvae undergo a period of growth and differentiation during a precompetence period (Crisp 1974, Hadfield 1978, Pechenik 1985, and for many species temperature, salinity, and larval nutrition influence the duration of this period (Hadfield 1977, Pechenik 1984, Pechenik & Lima 1984, Zimmerman & Pechenik 1991. At competence the larvae are morphologically and physiologically capable of undergoing metamorphosis, usually in the presence of an environmental cue associated with juvenile or adult habitats (Crisp 1974, Scheltema 1974, Pechenik 1980, Burke 1983, Pawlik 1992.…”

Competent larvae of the prosobranch gastropod Strombus glgas Linne (queen conch) require an environmental cue to induce metamorphosis. In this laboratory investigation the planktotrophic vehgers of S. gigas were exposed to 2 cues to observe changes In metamorphic response as a function of age. The cues were extract of Laurencia poitei, an artificial cue, and detrital blades of Thalassia testudinum, a natural cue. Onset of competence began 18 d post-hatch, and veligers were competent for only 6 d at 28 to 30°C. Both cues induced the highest percentage nletamorphosis on Day 23 (88% for extract and 78% for detritus), and response dropped dramatically by Day 25 ( 3 % for extract and 15% for detritus). Shell length for successful metainorphosis ranged between 952 and 1258 pm Pigmentation change from orange to dark green on the propodium and larval operculuni indicated competence, and competent veligers exhibited a swim-crawl behavior associated with settlement. Thls study revealed that veligers of S. gigas have a unique developmental hstory. The competence period was shorter than the precompetence period. Most other planktotrophic larvae a r e competent for a time equal to or longer than the precompetence period. Short-term competence is ordinarily associated with metamorphosis to a broad spectrum of cues. This may explain why veligers of S. gigas were observed to metamorphose to a variety of benthic cues found in juvenile conch seagrass habitats.

Previous research has shown that elevated temperature and environmental hypoxia are associated with a reduced representation of larger‐bodied species in communities of ectotherms, suggesting their competitive disadvantage resulting from increased oxygen demands and limited oxygen availability. To investigate this, we conducted a comparative analysis of two pairs of competing zooplankton species: Daphnia galeata (smaller‐bodied) and Daphnia pulex (larger‐bodied), as well as D. pulex (smaller‐bodied) and Daphnia magna (larger‐bodied). We monitored their population dynamics under different oxygen concentrations and temperatures, and additionally measured hemoglobin concentration in the latter pair. Contrary to expectations, the results demonstrated that the larger‐bodied species outcompeted the smaller‐bodied ones in all experimental treatments involving the first pair of species. In the second pair, elevated temperature favored the smaller‐bodied species, while environmental hypoxia had the opposite effect. The competitive advantage of D. pulex under elevated temperature likely stemmed from their ability to allocate energy from somatic growth to reproduction, as indicated by the increased number of reproducing females. Conversely, the competitive advantage of D. magna under environmental hypoxia may be attributed to their ability to reallocate energy from reproduction to somatic growth, as indicated by lower reproductive effort and greater plasticity in hemoglobin production. These findings indicate that elevated temperature and hypoxia can independently and jointly influence interspecific competitive abilities by impacting the pace of life. However, the numerical dominance of smaller‐sized species in warm and hypoxic zooplankton communities cannot be explained by their enhanced competitive abilities resulting from a more favorable oxygen supply demand balance.
