Response of blacktip reef sharks Carcharhinus melanopterus to shark bite mitigation products [PDF]

Scientific Reports, 2020
Globally, the frequency of shark bites is rising, resulting in an increasing demand for shark deterrents and measures to lessen the impact of shark bites on humans. Most existing shark protection measures are designed to reduce the probability of a bite,

Thermal tolerance and hypoxia tolerance are associated in blacktip reef shark (Carcharhinus melanopterus) neonates [PDF]

Journal of Experimental Biology, 2020
Thermal dependence of growth and metabolism can influence thermal preference and tolerance in marine ectotherms, including threatened and data-deficient species.

Microsatellite analyses of blacktip reef sharks (Carcharhinus melanopterus) in a fragmented environment show structured clusters. [PDF]

PLoS ONE, 2013
The population dynamics of shark species are generally poorly described because highly mobile marine life is challenging to investigate. Here we investigate the genetic population structure of the blacktip reef shark (Carcharhinus melanopterus) in French

Ethogram for blacktip reef sharks (Carcharhinus melanopterus)

Behaviour, 2023
The chondrichthyan lineage diverged from the osteichthyan line around 440 million years ago, resulting in a vast evolutionary gulf between modern elasmobranchs and other vertebrates.

Inferring leader-follower dynamics in three shark species using acoustic telemetry data [PDF]

Movement Ecology
Background Understanding collective behaviours and interactions in sharks is still in its infancy. Although recent studies have revealed some social structures in several shark species, little is known about complex interactions and social processes such

Spatial and temporal analysis of juvenile blacktip reef sharks (Carcharhinus melanopterus) demographics identifies critical habitats.

Journal of Fish Biology, 2023
Reef shark species have undergone sharp declines in recent decades, as they inhabit coastal areas, making them an easy target in fisheries (i.e., sharks are exploited globally for their fins, meat, and liver oil) and exposes them to other threats (e.g ...

Behaviour of mesopredatory coral reef fishes in response to threats from sharks and humans [PDF]

Scientific Reports, 2023
Both sharks and humans present a potentially lethal threat to mesopredatory fishes in coral reef systems, with implications for both population dynamics and the role of mesopredatory fishes in reef ecosystems.

The COVID-19 pandemic and the impact on the absence of diver-shark interaction on blacktip reef shark’s agonistic behavior: Morotai case

IOP Conference Series: Earth and Environmental Science, 2021
Prior to COVID-19 pandemic, Morotai waters was well known as one of the favorite destination for shark watching tourism in Indonesia. Similar to other animal sighting tourism in Indonesia, shark diving has been hit hard by the pandemic of COVID-19 and ...

Safety in the shallows: nearshore coastal habitats can provide physical and thermal features that optimize escape performance in newborn blacktip reef sharks (<i>Carcharhinus melanopterus</i>). [PDF]

Conserv Physiol
The prevailing shark nursery paradigm suggests that high survival in these habitats is primarily driven by reduced predator encounters: so-called pre-encounter risk. In this study, we propose an alternative or complementary mechanism: that some nurseries

Home range of newborn blacktip reef sharks (Carcharhinus melanopterus), as estimated using mark-recapture and acoustic telemetry [PDF]

Coral Reefs, 2020
Sharks play important functional roles in coral reef ecosystems. Studying reef shark populations’ spatial ecology also contributes important data for effective conservation planning. The purpose of this study was to define the home range of neonatal blacktip reef sharks (Carcharhinus melanopterus) around Moorea, French Polynesia, and compare estimates ...
