Corals are in decline worldwide due to local anthropogenic stressors, such as nutrient loading, and global ocean warming. Anthropogenic which is often rich nitrate, inhibits coral growth worsens corals’ response warming while natural sources of nitrogen, ammonium from fish excretion, promotes growth.

Abstract Coral disease is becoming increasingly problematic on reefs worldwide. However, most coral research has focused the abiotic drivers of disease, potentially overlooking role species interactions in dynamics. predators particular can influence by breaking through protective tissues and exposing corals to infections, vectoring diseases among corals, or serving as reservoirs for pathogens. Numerous studies have demonstrated relationship between corallivores certain contexts, but date there been no comprehensive synthesis relationships which hinders our understanding To address this void, we identified 65 from 26 different ecoregions that examine predator–prey-disease relationship. Observational found over 20 positive correlations prevalence corallivore abundance, with just four instances documenting a negative correlation disease. Studies putative pathogens guts experiments ability vector Corallivores were also frequently infesting margins targeting diseased tissues, ecological ramifications behavior remains unknown. We impact was taxon-dependent, invertebrates increasing incidence, prevalence, progression; fish showing highly context-dependent effects; xanthid crabs decreasing progression. Simulated wounding caused many cases, experimental wound debridement slowed progression others, could explain contrasting findings taxa. The effects are likely worsen storms intensify, macroalgal cover increases, more nutrients added marine systems, water temperatures increase. As continue globally, complete dynamics disease—including those involving predators—is paramount importance reef conservation management.

Mechanical injury is a prevalent challenge in the lives of animals with myriad potential consequences for organisms, including reduced fitness and death. Research on animal has focused many aspects, frequency severity wounding wild populations, short- long-term at different biological scales, variation response to within or among individuals, species, ontogenies, environmental contexts. However, relevant research scattered across diverse subdisciplines, study effects lacked synthesis coherence. Furthermore, depth knowledge biology highly uneven terms scope taxonomic coverage: much biomedical focus, using mammalian model systems investigating cellular molecular processes, while organismal higher that explicitly comparative, invertebrate non-mammalian vertebrate species less common often well integrated into core body about injury. The current state presents an opportunity unify conceptually work focusing range questions, synthesize progress date, identify fruitful avenues future research. central aim this review concerning broad mechanical animals. We organize reviewed by four loosely defined levels organization: effects, physiological behavioural ecological evolutionary Throughout, we highlight diversity groups emphasizing gaps coverage, causal understanding, endpoints considered. additionally discuss importance integrating levels, how initial, localized responses can lead scale individual beyond. also suggest important research, distinguishing better between related yet distinct phenomena, expanding subjects include greater variety testing intrinsic extrinsic conditions affect sensitivity responses.

Monitoring of reef restoration efforts and artificial reefs (ARs) has typically been limited to coral fragment survival, hampering evaluation broader objectives such as ecosystem recovery. This study aimed determine what extent AR design influences the ecological recovery restored by monitoring outplanted fragments, benthic cover, recruitment fish invertebrate communities for two years. Four designs (16 m 2 ), unrestored controls natural patches reference (n = 10) were established in Mkwiro, Kenya. ARs consisted either concrete disks with bottles, layered disks, metal cages or a combination thereof. A mixture 18 branching species (mainly Acropora spp.) was on at density 7 corals -2 . After years, 60% all fragments had survived, already resulting cover most comparable (though -dominated) patches.

Abstract There is mounting evidence that the deoxygenation of coastal marine ecosystems has been underestimated, particularly in tropics. These physical conditions appear to have far‐reaching consequences for communities and associated with mass mortalities. Yet little known about hypoxia tropical habitats or effects it on reef‐associated benthic organisms. We explored patterns dissolved oxygen (DO) throughout Almirante Bay, Panama found a hypoxic gradient, areas closest mainland having largest diel variation DO, as well more frequent persistent hypoxia. then designed laboratory experiment replicating most extreme situ DO regime shallow patch reefs (3 m) assess response corallivorous fireworm, Hermodice carnaculata Worms were exposed (8 hr ~ 1 mg/L 3.2 kPa) 16 times over an 8‐week period, at 4 8 weeks, their consumption (respiration rates) was measured upon reoxygenation, along regrowth severed gills. Exposure low resulted worms regenerating significantly larger gills compared under normoxia. This coupled ability maintain elevated consumption/respiration rates after exposure. In contrast, from normoxic treatment had depressed respiration being (week 8). indicates oxygen‐mediated plasticity both gill morphology physiology may confer tolerance increasingly severe one important coral predator reef decline.
