Fish reproductive success is linked to the ability of couples to mate and produce clutches that successfully hatch. Environmental stressors like high temperature and low pH can jeopardize this energetically costly process. In this study, exposure to high temperature and low pH was tested on a marine temperate species, Gobiusculus flavescens, to evaluate effects on reproductive performance. Breeding pairs were assigned to different temperatures (+ 0 °C, + 3 °C relative to in situ temperature) and pH levels (8.0, 7.6), in a cross-factorial design for a 3-month period. Reproduction activity, success, and paternal investment were measured throughout the exposure period. Results show reproduction is impaired by elevated temperature, while low pH had little impact. Breeding pairs under high temperature had 3% to 10% hatching success, up to 30% less eggs and eggs up to 20% smaller. Although paternal investment was not affected by tested parameters, males of breeding pairs exposed to elevated temperature had smaller gonadosomatic indexes, which might indicate a lack of investment in the reproductive process. Overall, results show that elevated temperature, expected more frequently in the near future, as a consequence of global warming, may impair key processes like reproduction in temperate fish, with potential consequences for fitness and population replenishment.

“…For example, Leo et al (2018) suggest that the differing responses to high pCO 2 observed in Atlantic herring, a congener species to Pacific herring, may be explained by environmental acclimation. High pCO 2 is regularly observed in the Kiel Fjord, and little to no effect of highly elevated pCO 2 was observed in Atlantic herring larvae from this location (Franke and Clemmesen, 2011), compared to significant effects in larvae from populations spawning in relatively low pCO 2 in the Oslo Fjord (Frommel et al, 2011;Leo et al, 2018). Diel and tidal cycles in coastal environments may also contribute to a lack of embryo sensitivity to elevated pCO 2 (Cross et al, 2019).…”

Ocean Acidification and Ocean Warming Effects on Pacific Herring (Clupea pallasi) Early Life Stages

Increasing green house gas emissions are expected to raise surface seawater temperatures and lead to locally intensified ocean acidity in the U.S. Pacific Northwest. Pacific herring (Clupea pallasi) are ecologically and economically important forage fish species native to this region. While the impacts of ocean acidification and ocean warming on organism physiology have been extensively studied, less is known on how concurrent climate change stressors will affect marine fish. Therefore, our study focused on the combined effects of ocean acidification and warming on Pacific herring early life history stages. Pacific herring embryos were incubated under a factorial design of two temperature (10°C or 16°C) and two pCO2 (600 μatm or 1200 μatm) treatments from fertilization until hatch (6 to 15 days depending on temperature). Elevated pCO2 was associated with a small increase in embryo mortality. Elevated temperature, as a single stressor, generated greater embryo mortality and embryo heart rates, larger yolk areas upon hatch, lower hatching success, and shorter larval lengths; compared with the same parameters measured under ambient temperature. The interaction of elevated temperature and pCO2 was associated with greater embryo heart rates and yolk areas compared to ambient conditions. This study suggests that while temperature is the primary global change stressor affecting Pacific herring embryology, interaction effects with pCO2 could introduce additional physiological challenges.

“…Therefore, despite the fact that studies on the energetic results of human disturbance in bioindicator species are limited to a few examples (Adams & Ham, 2011;Toro, Navarro, & Palma-Fleming, 2003), there are several examples to show that alterations in the physiological/energetic conditions of nonbioindicator organisms are due to direct (Williams, Lusseau, & Hammond, 2006;Symons, Pirotta, & Lusseau, 2014;Villegas-Amtmann, Schwarz, Sumich, & Costa, 2015) and indirect human impacts (Griffen, 2018;Leo, Dahlke, Storch, Pörtner, & Mark, 2018;Thomas et al, 2016).…”

“…Species may also alter their feeding habits (Griffiths et al, ; Jokimäki, Suhonen, Jokimäki‐Kaisanlahti, & Carbó‐Ramírez, ) and trophic interactions (Costa, Tavares, Suciu, Rangel, & Zalmon, ; Gray, Baldauf, Mayhew, & Hill, ) in areas with human disturbance, and thus these changes in behavior and daily activities can result in changes to the energy balance and physiological state (Chandurvelan, Marsden, Glover, & Gaw, ; Spellerberg, ). Therefore, despite the fact that studies on the energetic results of human disturbance in bioindicator species are limited to a few examples (Adams & Ham, ; Toro, Navarro, & Palma‐Fleming, ), there are several examples to show that alterations in the physiological/energetic conditions of nonbioindicator organisms are due to direct (Williams, Lusseau, & Hammond, ; Symons, Pirotta, & Lusseau, ; Villegas‐Amtmann, Schwarz, Sumich, & Costa, ) and indirect human impacts (Griffen, ; Leo, Dahlke, Storch, Pörtner, & Mark, ; Thomas et al, ).…”

Burrowing behavior and burrowing energetics of a bioindicator under human disturbance

Bioindicator species are extensively used for rapid assessment of ecological changes. Their use commonly focuses on changes in population abundance and individual sizes in response to environmental change. These numerical and demographic shifts likely have behavioral and physiological mechanistic drivers that, if understood, could provide additional insights into the use of these species as bioindicators of habitat health. The Atlantic ghost crab, Ocypode quadrata, is a global bioindicator species of human disturbance on sandy shores. Individual size and population abundance of O. quadrata decline dramatically at sites with human disturbance, and the causes of this phenomenon remain unclear. Here, we test the hypothesis that individual and population‐level changes at disturbed sites reflect changes in burrowing behavior and energetics. Specifically, we examine whether or not the burrowing behavior (e.g., burrow fidelity and longevity) of O. quadrata changes because of human disturbance. We also examine energy required for burrowing by O. quadrata across different levels of human disturbance. We show that O. quadrata have the highest burrow fidelity and longevity at sites with low level of human impact, and weakest burrow fidelity and longevity at pristine sites. O. quadrata reduce the burrowing energy allocation by manipulating the burrow dimension and increasing the burrow longevity even under low levels of human disturbance. Overall, this study shows that human disturbances not only change the behavior of organisms, but also shift energetic balance. Our results support the use of a bioenergetic approach to better understand how human disturbances influence natural populations, and the specific use of this approach with this bioindicator species.
