Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Changing Trends in Cetacean Strandings in the East China Sea: Identifying Relevant Variables and Implications for Conservation and Management

Diversity, 2023
The frequency of cetacean strandings is increasing, with multiple causes identified. We examined temporal and spatial trends in stranding numbers along the coastal areas of the East China Sea from 1990 to 2021.

Brucella ceti and Brucellosis in Cetaceans [PDF]

Frontiers in Cellular and Infection Microbiology, 2012
Since the first case of brucellosis detected in a dolphin aborted fetus, an increasing number of Brucella ceti isolates has been reported in members of the two suborders of cetaceans: Mysticeti and Odontoceti. Serological surveys have shown that cetacean brucellosis may be distributed worldwide in the oceans. Although all B.

Using spatial capture–recapture methods to estimate long‐term spatiotemporal variation of a wide‐ranging marine species

Ecography, EarlyView.
Determining population status to inform mitigation of anthropogenic threats requires statistical approaches that investigate spatial and temporal variation. In the face of climate change it is increasingly important to differentiate between changes in population size and redistributions of populations.

The secret acoustic world of leopards: A paired camera trap and bioacoustics survey facilitates the individual identification of leopards via their roars

Remote Sensing in Ecology and Conservation, EarlyView.
Here, we conducted the first large‐scale joint camera trap and bioacoustics survey for large African carnivores in Nyerere National Park, Tanzania. By combining the different data types that each technology produced, this led to the discovery that every leopard has a unique, identifiable roar which enables leopards to be the focus of other, more ...

The loss of taste genes in cetaceans [PDF]

BMC Evolutionary Biology, 2014
Five basic taste modalities, sour, sweet, bitter, salt and umami, can be distinguished by humans and are fundamental for physical and ecological adaptations in mammals. Molecular genetic studies of the receptor genes for these tastes have been conducted in terrestrial mammals; however, little is known about the evolution and adaptation of these genes ...

Automated extraction of right whale morphometric data from drone aerial photographs

Remote Sensing in Ecology and Conservation, EarlyView.
Aerial photogrammetry is a popular non‐invasive method for measuring marine mammal body size, body morphometrics, and body condition, but processing large datasets efficiently remains challenging. We developed a machine learning algorithm using Mask R‐CNN models to automatically measure body morphometrics of southern right whales from aerial ...

Microsatellites in Cetaceans: An Overview [PDF]

The Open Marine Biology Journal, 2008
This paper presents a comprehensive overview of the published literature on microsatellites studied in cetace- ans from 1989 to 2007. We inventoried 246 loci isolated from 18 and amplified in 51 cetacean species representing 11 families. The majority of loci (68%) were dinucleotide (CA) repeats, which were also shown to be on average more vari- able ...

Stable social structure of spotted hyenas Crocuta crocuta during the dry and wet season in Central Tuli, Botswana

Wildlife Biology, EarlyView.
Group‐living animals often exhibit dynamic social structures, with fission–fusion behavior enabling adaptive responses to environmental changes. Spotted hyenas Crocuta crocuta are large carnivores with complex social dynamics influenced by intrinsic factors, such as rank and kinship, and extrinsic factors, such as prey availability.
