A phenomenon of transience in the humpback whale population breeding in New Caledonia has been highlighted in recent analyses. We used these data to illustrate the risk of flawed inference when transience is not properly accounted for in abundance estimation of resident populations. Transients are commonly defined as individuals that pass through t...

A topic of particular current interest is community-level approaches to species distribution modelling (SDM), i.e. approaches that simultaneously analyse distributional data for multiple species. Previous studies have looked at the advan- tages of community-level approaches for parameter estimation, but not for model selection – the process of choo...

1. Mark–recapture studies are often used to estimate population size based on a single source of individual identification data such as natural markings or artificial tags. However, with the development of molecular ecology, multiple sources of identification can be obtained for some species and combining them to obtain population size estimates wo...

This chapter presents the development of a simple and intuitive platform for hosting, processing and presenting information in real time in an IoT environment, regardless of the nature of collected data. To this end, an architecture based on microservices is proposed, which is presented as a modular and scalable solution; this guarantees compatibil...

Research data collected during scientific projects financed by public funds must be reusable not only by the scientific community which produces them, but also by the civil society who finances the projects through taxes. The systematic provision of publicly financed research data is an important condition for the reproducibility of science and the...

It brings together 17 research infrastructures (RIs) and networks to provide a broad range of services to infectious disease researchers. An efficient and structured treatment of data is central to ISIDORe’s aim to furnish seamless access to its mu...

Ports are urban and often quite-confined habitats within the aquatic (marine or freshwater) ecosystems, hosting biodiversity as any natural ecosystem under anthropogenic pressures as in many urban ecosystems. This scoping review seeks to give an overview of the state of knowledge on port biodiversity and port concerns about biodiversity based on sc...

Semantic interoperability (SI) is at the heart of the FAIR principles and of the design of large scale cross disciplinary infrastructures. The European Open Science Cloud (EOSC) is a European-wide effort towards such an infrastructure, aiming to deepen the regional research collaboration and realising a shared data space for science, research and i...

The Mediterranean fin whale (Balaenoptera physalus) subpopulation is under threat from collisions with ships. Given the international dimension of the issue, the French, Italian, Monegasque and Spanish governments have proposed a Particularly Sensitive Sea Area (PSSA), i.e., a management zone of the International Maritime Organization (IMO), in whi...

FAIR and open data is not a simple, static and achievable one-step process. Challenges emerge when structuring, sharing and opening up research data, multidisciplinary in particular. An iterative approach is necessary, above all, to achieve sufficient formalism for the data to be readable also by machines and to comply with the requirements of the...

Maritime transportation forecasts project an increase in shipping. In this context, interactions with cetaceans are of growing concern especially when relevant biological data are not available to monitor the impacts. The Agoa sanctuary in the Wider Caribbean region faces this situation. To overcome this issue, we used AIS data to estimate three pr...

The long-term monitoring of long-lived animals often requires individual identification. For cetaceans, this identification may be based on morphological characters observable from a boat such as shape, spots and cuts of the back, fluke and dorsal fins. However, for some species such as the sperm whales (Physeter macrocephalus), this approach may b...

Adult male sperm whales (Physeter macrocephalus) are long distance runners of the marine realm, feeding in high latitudes and mating in tropical and subtropical waters where stable social groups of females and immatures live. Several areas of uncertainty still limit our understanding of their social and breeding behavior, in particular concerning t...

Les impacts humains et leur atténuation dépendent de notre capacité à mobiliser la recherche au niveau mondial. Le développement durable de la société dépendra en grande partie du développement sur le long terme d’une science globale et d’outi...

Le biomonitoring du milieu marin, mis en place pour caractériser l’état écologique d’un milieu, ou évaluer les effets des protocoles de gestion environnementale, permet le développement d'une compréhension scientifique de l'environnement marin et des impacts des humains sur celui-ci. Les méthodes traditionnelles de biomonitoring sont généralement b...

Background In the French West Indies, more than 20 species of cetaceans have been observed over the last decades. The recognition of this hotspot of biodiversity of marine mammals, observed in the French Exclusive Economic Zone of the West Indies, motivated the French government to create in 2010 a marine protected area (MPA) dedicated to the conse...

Several areas of uncertainty still limit our understanding of their social and breeding behaviour, in particular concerning...

We are now facing profound changes (biodiversity, climate, pandemic, etc.). Human impacts and their mitigation will depend on our ability to mobilize research at the global level. The sustainable development of the society will largely depend on the sustainable development of global science and scientific research tools, outputs, and research ecosy...

Database collected as part of the Lorraine Coché master's 2 internship "Inventory and structuring of marine mammal observation data around Guadeloupe" in 2020 (Master Tropical marine ecosystems at the University of the Antilles). This database centralizes and harmonizes the data collected by the team of the Agoa Sanctuary (Aire Marine Protégée), th...

The long-term monitoring of long-lived animal populations often requires individual identification. For cetacean populations, this identification is mostly based on morphological characters observable from a boat such as shape, spots and cuts of the back, caudal and dorsal fins. This is well suited for species easily displaying their caudal fins, s...

Understanding the organization and dynamics of social groups of marine mammals through the study of kin relationships is particularly challenging. Here, we studied a stable social group of sperm whales off Mauritius, using underwater observations, individual-specific identification, non-invasive sampling and genetic analyses based on mitochondrial...

Lay summary For polygamous long-migrant birds, the choice of migration strategy depends on social pressure and experience and influences the chance of survival. If you are a male, you’d better leave early in the spring to secure the best site to show off. In fall, juveniles have a hard time surviving to migration as they leave before the adults and...

Nowadays shipping has been identified as the major contributor to ocean noise (NRC, 2003; Hildebrand, 2009). The anthropogenic sound sources constitute a pressure on marine mammals (Southall, 2007). Mysticetes, such as the fin whale Balaenoptera physalus, are mammals that emit at low frequencies, are presumably more likely to be disturbed by low fr...

Data produced within marine and terrestrial biodiversity research projects that evaluate and monitor Good Environmental Status, have a high potential for use by stakeholders involved in environmental management. However, environmental data, especially in ecology, are not readily accessible to various users. The specific scientific goals and the log...

The Bornean elephant (Elephas maximus borneensis) is one of the four sub-species of Asian elephants and can be found only in Sabah, Malaysia. Recent estimates assessed the total population of Bornean elephants as being around 2040 individuals (range: 1184 to 3652), making this the most endangered elephant species in Asia (currently listed as Endang...

The recent development of tracking tools has improved our nascent knowledge on animal movement. Because of model complexity, unrealistic a priori hypotheses and heavy computational resources, behavioral changes along an animal path are still often assessed visually. A new avenue has recently been opened with change point algorithms because tracking...

After decades of whaling, Oceania humpback whales Megaptera novaeangliae have such a low rate of recovery that a trend is not currently measurable. They are listed as Endangered by the IUCN, and any possible threat to the whales needs to be carefully monitored and mitigated. Whale-watching activities represent an important economic development thro...

Estimating the abundance of long-lived, migratory animals is challenging but essential for managing populations. We provide the first abundance estimates of endangered humpback whales Megaptera novaeangliae from their breeding grounds in Oceania, South Pacific. Using fluke photo-identification (1999−2004, n = 660 individuals) and microsatellite gen...

The coastal waters of Baja California Sur, Mexico, include some of the most important foraging grounds of the East Pacific green turtle Chelonia mydas. However, they are also important fishing grounds for artisanal fleets, leading potentially to high levels of bycatch mortality. We studied the impact of a small-scale gill-net fishery at San Ignacio...

I propose a modification of the Jolly-Seber model, the two-source Jolly-Seber (TSJS) model, to estimate population size by combining two sources of capture-recapture data of the same population where there might be an unknown overlap between two datasets. This is the case with recent surveys of whales and dolphins where researchers use individual i...

In recent years, whale and dolphin watching activities have developed rapidly in the South Pacific Island region. In particular, the presence of humpback whales during winter months attracts thousands of tourists every year. New Caledonia is one of the leading countries for humpback whale-watching in this region, with the industry focusing on the w...

Aerial surveys for Bryde's whales Balaenoptera cf. brydei were undertaken over the Hauraki Gulf and northeastern coast of New Zealand between 1999 and 2003. Whales were sighted in all months, with usually more whales seen in summer. The density of whales within the Hauraki Gulf was examined in relation to geographical location and sea surface tempe...

The abundance of humpback whales on winter breeding grounds throughout Oceania (South Pacific) was estimated by sighting- resighting analysis of individual identification photographs collected from 1999 to 2004.
