Effects of climate change on fish reproduction and early life history stages

Marine and Freshwater Research, Journal Year: 2011, Volume and Issue: 62(9), P. 1015 - 1015

Seasonal change in temperature has a profound effect on reproduction fish. Increasing temperatures cue reproductive development spring-spawning species, and falling stimulate autumn-spawners. Elevated truncate spring spawning, delay autumn spawning. Temperature increases will affect reproduction, but the nature of these effects depend period amplitude increase range from phase-shifting spawning to complete inhibition reproduction. This latter be most marked species that are constrained their capacity shift geographic range. Studies taxa, habitats ranges all show inhibitory elevated albeit about different environmental set points. The generated through endocrine system, particularly ovarian oestrogen production. Larval fishes usually more sensitive than adults fluctuations, might especially vulnerable climate change. In addition direct embryonic duration egg survival, also influences size at hatching, developmental rate, pelagic larval survival.

Ocean acidification disrupts the innate ability of fish to detect predator olfactory cues

Ecology Letters, Journal Year: 2009, Volume and Issue: 13(1), P. 68 - 75

Abstract While ocean acidification is predicted to threaten marine biodiversity, the processes that directly impact species persistence are not well understood. For species, early life history stages inherently vulnerable predators and an innate ability detect can be critical for survival. However, whether or inhibits predator detection unknown. Here, we show newly hatched larvae of fish Amphiprion percula innately using olfactory cues this retained through settlement. Aquarium‐reared larvae, previously exposed predators, were able distinguish between predatory non‐predatory species. when eggs seawater simulating (pH 7.8 1000 p.p.m. CO 2 ) settlement‐stage became strongly attracted smell discriminate non‐predators was lost. Newly unaffected by exposure still fish. If impairment preferences in translates higher mortality as a result increased predation risk, there could direct consequences replenishment sustainability populations.

A review of ecogeochemistry approaches to estimating movements of marine animals

Limnology and Oceanography, Journal Year: 2013, Volume and Issue: 58(2), P. 697 - 714

Published: March 1, 2013

Ecogeochemistry—the application of geochemical techniques to fundamental questions in population and community ecology—has been used animal migration studies terrestrial environments for several decades; however, the approach has received far less attention marine systems. This review includes comprehensive meta‐analyses organic zooplankton δ 13 C 15 N values at base food web, dissolved inorganic carbon values, seawater 18 O create, first time, robust isoscapes Atlantic Ocean. These present greater geographic variability multiple tracers than was previously thought, thus forming foundation reconstructions habitat use patterns organisms. We additional tracers, including trace‐element‐to‐calcium ratios heavy element stable isotopes, examine anadromous migrations. highlight value ecogeochemistry by examining case on three components connectivity: dispersal natal homing, functional connectivity, migratory connectivity. also discuss recent advances compound‐specific nitrogen isotope analyses tracking movement. A better understanding isotopic routing fractionation factors, particularly individual compound classes, is necessary realize full potential ecogeochemistry.

Animal behaviour shapes the ecological effects of ocean acidification and warming: moving from individual to community‐level responses

Global Change Biology, Journal Year: 2015, Volume and Issue: 22(3), P. 974 - 989

Abstract Biological communities are shaped by complex interactions between organisms and their environment as well with other species. Humans rapidly changing the marine through increasing greenhouse gas emissions, resulting in ocean warming acidification. The first response animals to environmental change is predominantly modification of behaviour, which turn affects species ecological processes. Yet, many climate studies ignore animal behaviour. Furthermore, our current knowledge how global alters behaviour mostly restricted single species, life phases stressors, leading an incomplete view coinciding stressors can affect that structure biological communities. Here, we review on effects acidification animals. We demonstrate pervasive a wide range critical behaviours determine persistence success then evaluate several approaches studying acidification, identify gaps need be filled, better understand will populations altered behaviours. Our provides synthesis far‐reaching consequences behavioural changes could have for ecosystems environment. Without considering limit ability forecast impacts provide insights aid management strategies.

Abstract Aim The Red Sea is characterised by a unique fauna and historical periods of desiccation, hypersalinity intermittent isolation. origin contemporary composition reef‐associated taxa in this region can illuminate biogeographical principles about vicariance the establishment (or local extirpation) existing species. Here we aim to: (1) outline distribution shallow water between adjacent regions, (2) explore mechanisms for maintaining these distributions (3) propose hypotheses to test mechanisms. Location Sea, Gulf Aden, Arabian Indian Ocean. Methods Updated checklists scleractinian corals, fishes non‐coral invertebrates were used determine species richness rest Peninsula assess levels endemism.
