Cuticle relative atomic weight composition of juvenile California spiny lobsters (Panulirus interruptus) in response to ocean acidification ...

We examined the response of multiple structures used for predator defense in the California spiny lobster, Panulirus interruptus, to a series of ocean acidification-like conditions. Lobsters were collected by modified commercial traps offshore La Jolla, CA (in the area around 32.8534193, -117.268751...

Description
Summary:We examined the response of multiple structures used for predator defense in the California spiny lobster, Panulirus interruptus, to a series of ocean acidification-like conditions. Lobsters were collected by modified commercial traps offshore La Jolla, CA (in the area around 32.8534193, -117.2687516) in October 2016 and held at ambient conditions (pH 7.97, 16.5°C) before exposure to stable or diurnally fluctuating reduced pH conditions established by bubbling CO2 and as measured using best practices (ambient pH/stable, 7.97, 16.5°C; reduced pH/stable 7.67, 16.6°C; reduced pH with low fluctuations, 7.67 ± 0.05, 16.4°C; reduced pH with high fluctuations, 7.67 ± 0.10, 16.4°C). After three months, we examined the relative atomic weight composition (weight %/atomic weight of element) of the carapace using a scanning electron microscope (SEM) equipped with electron-dispersive x-ray spectroscopy (EDX). Each cuticle sample was rinsed with deionized water and allowed to air dry. Samples were then freeze-fractured ...
