“…Most studies focused on real-time effects of UV-B of marine organisms (Lamare, Burritt & Lister, 2011). UV-B radiation probably brings about long-term and transgenerational carryover effects on the fitness of marine invertebrates (Zhao et al, 2018a), because UV-B causes cellular damage by oxidizing proteins, DNA and membrane lipids cannot immediately recover or even irreversible (Adams & Shick, 2001).…”

“…This probably results in fertilization interference, delayed development (Lamare, Burritt & Lister, 2011), impaired skeletal formation (Bonaventura et al, 2005; Nahon et al, 2009) and apoptosis (Lesser, Kruse & Barry, 2003). The sea urchin Strongylocentrotus intermedius , a representative keystone ecosystem engineer in intertidal and shallow seas around Japan, Korea, northeastern China and Far East Russia (Agatsuma, 2013), are sensitive and susceptible to UV-B radiation (Zhao et al, 2018a) through their entire biological development, including gametes, fertilization and embryonic and larval development (Lamare, Burritt & Lister, 2011). It is especially essential to consider of the annual dose of UV-B radiation around the areas, where Strongylocentrotus intermedius exist.…”

“…Although the data of UV-B radiation was observed by land-based spectroradiometers. Recently, short-term (1 h) UV-B radiation (20 μW ∙ cm −2 ) showed significantly adverse effects on survival, food consumption, test diameter, test height, test height:test diameter, gonad weight and crude protein of gonads of Strongylocentrotus intermedius , despite the absence of UV-B radiation for 8 weeks (Zhao et al, 2018a). Therefore, we hypothesized that transgenerational effects of short-term (1 h) UV-B radiation (20 μW ∙ cm −2 ) exist in Strongylocentrotus intermedius (for example, egg size, fertilization, hatchability and larval size).…”

Transgenerational effects are important for phenotypic plasticity and adaptation of marine invertebrates in the changing ocean. Ultraviolet-B (UV-B) radiation is an increasing threat to marine invertebrates. For the first time, we reported positive and negative transgenerational effects of UV-B radiation on egg size, fertilization, hatchability and larval size of a marine invertebrate. Strongylocentrotus intermedius exposed to UV-B radiation showed positive transgenerational effects and adaptation on egg size, hatching rate and post-oral arm length of larvae. Negative transgenerational effects were found in body length, stomach length and stomach width of larvae whose parents were exposed to UV-B radiation. Sires probably play important roles in transgenerational effects of UV-B. The present study provides valuable information into transgenerational effects of UV-B radiation on fitness related traits of sea urchins (at least Strongylocentrotus intermedius).

Understanding the ecological role of shelters is greatly hampered by the scarcity of long-term laboratory experiments on the trade-off between fitness benefits and costs. This lack probably leads to an underestimation of the negative and/or positive effects on behaviors and growth of marine invertebrates in benthic ecosystems. Although our previous study revealed a significant effect on fitness-related traits of Glyptocidaris crenularis after 31 months, the present study extended it and investigated fitness benefits and/or costs of long-term sheltering on sea urchins to over 7 years. The present long-term study suggests that the previously reported reduction in feeding rate probably resulted from a reduction in reflexive feeding motions (Aristotle’s lantern reflex) rather than changes in foraging behavior. Actively seeking sheltering behavior was negatively impacted in individuals with continuous access to shelters. However, covering and righting behaviors did not differ in sheltered sea urchins, indicating that these behaviors are maintained to escape from adverse environments regardless of shelter. Body size of sea urchins in the group with shelters was significantly lower than those without shelters after 7 years. Weights of gonads and gut were not significantly different after 7 years despite previous observations of differences after ~2.5 years. The present study provides valuable information on the trade-off between fitness benefits and costs to sea urchins residing in shelters. However, the present study is only a laboratory investigation for one urchin species (G. crenularis) which does not consider the complexity of natural environments. Field studies should be carried out with G. crenularis and other sea urchin species, before a more universal conclusion can be drawn.

Older Amphibian Larvae Are More Sensitive to Ultraviolet Radiation and Experience More Sublethal Carryover Effects Post‐Metamorphosis

Elevated ultraviolet radiation (UVR) is postulated as one of multiple, interrelated environmental stressors driving amphibian population declines globally. However, key knowledge gaps remain in elucidating the link between elevated UVR and amphibian declines in a changing climate, including whether timing and irradiance of UVR exposure in early life dictates the onset of detrimental carryover effects post‐metamorphosis. In this study, striped marsh frog larvae (Limnodynastes peronii) were exposed to UVR at one of two different irradiances for up to 7 days, either as hatchlings (Gosner stage 23) or as older larvae (Gosner stage 25−28). These animals were then reared to metamorphosis in the absence of UVR to examine independent and interactive carryover effects throughout development. Older larvae were more sensitive to UVR than hatchlings, with 53.1% and 15.6% mortality in larvae exposed to high and low irradiance respectively, compared with no mortality of hatchlings in either irradiance treatment. Irradiance and timing of UVR exposure had interactive effects on larval body length, causing stunted growth patterns and a lack of compensatory growth following UVR exposure, particularly in animals exposed to high irradiance UVR later in development. Timing of UVR exposure also determined the severity of carryover effects into metamorphosis, including delayed metamorphosis and the first published account (to our knowledge) of latent UVR‐induced depigmentation in an amphibian. These findings highlight how acute changes to the larval UVR exposure regime can impact on amphibian health later in life, with implications for our understanding of the effects of climate change on UVR‐related amphibian declines.
