Relationships between larval nutritional experience, larval growth rates, juvenile growth rates, and juvenile feeding rates in the prosobranch gastropod Crepidula fornicata

Effects of short-term food variability on the plasticity of age and size at metamorphosis of porcelain crab larvae

“…Before being able to metamorphose in response to an external cue, such larvae must first develop a competency to perceive and respond to the cue. For these larvae, the timing of competence represents an end to the portion of the larval period in which the development rate can be influenced by food variability (Pawlik and Mense 1994;Pechenik et al 1996b;Davis 1998). When studying the larvae of cue-dependent invertebrates, the end of the precompetent period represents an ecologically relevant analogy to the ''timing of metamorphosis'' discussed in Hentschel (1999).…”

“…The majority of studies examining short-term food variability that occurs during larval development have focused on periodic starvation in filtered seawater (see McEdward and Qian 2001;Pechenik et al 2002;Moran and Manahan 2004). Although periodic starvation can provide many insights into larval physiology, larvae in nature will never encounter conditions as extreme as filtered seawater.…”

“…Although periodic starvation can provide many insights into larval physiology, larvae in nature will never encounter conditions as extreme as filtered seawater. Drawing ecological conclusions about the effects of short-term food variability on larval development requires experiments involving less extreme variability on a range of scales (see Pechenik et al 1996a;Davis 1998;Hentschel and Emlet 2000).…”

Acoplamento Plâncton-Bentos: O Papel Do Suprimento Larval Na Estrutura Das Comunidades Bentônicas De Costões Rochosos

“…Larvas liberadas ao longo da estação reprodutiva não gerariam juvenis de mesma qualidade, ou seja, com igual capacidade de crescimento e sobrevivência (Jarret & Pechenik 1997). A qualidade fi siológica pode estar determinada por fatores que atuam desde a produção (e qualidade) de ovos pelos adultos (Toonen & Pawlik 1994), a disponibilidade de alimento durante a fase larval no caso de larvas planctotrófi cas (Pechenik et al 2002), até a quantidade de tempo que a fase planctônica é estendida devido à falta de condições adequadas para a fi xação e metamorfose (Marshall & Keough 2003, Pechenik 2006. O estudo com larvas de Cirripedia realizado por Miron et al (1999) em campo revelou que a condição fi siológica das larvas cipris diminui ao longo do tempo, possivelmente pelo fato destas não se alimentarem neste estágio fi nal de desenvolvimento, o que as leva a consumir gradualmente suas reservas energéticas.…”

Chlorophyll-a and the Supply Side Ecology: Lessons from the Rocky Shores

“…Larval itness is inluenced by environmental conditions experienced by adults and larvae [10,11]. The efects of phytoplankton on larval dynamics depend on the phase of larval development [12][13][14][15] and may be stronger when variations in phytoplankton occur on temporal scales that larvae or breeding adults are able to respond [16]. The direct interaction between phytoplankton and the larval stages have short-term consequences for larval dynamics (e.g., Ref.…”
