DOI: 10.1002/ece3.8604
Abstract: Abstract Acoustic communication is important for animals with dependent young, particularly when they are spatially separated. Maternal humpback whales (Megaptera novaeangliae) use acoustic calling to help minimize the risk of separation from their young calves… read more here.

The eavesdropping risk of conspicuous sexual signaling in humpback whales

DOI: 10.1007/s00265-021-03048-7
Abstract: Conspicuous signals, such as acoustic sexual signals, can be “risky” in that they may be overheard by competitors. This means the signaller must balance the benefits of signaling to the intended receiver with the costs… read more here.

Abstract: Although the global use of the 1,1,1-trichloro-2,2-bis (4-chlorophenyl) ethane (p,p'-DDT) has been prohibited, its persistence in the environment has caused long-lasting exposure on marine mammals. Our previous studies revealed exceedingly high residue levels of DDTs… read more here.

DOI: 10.1016/j.envpol.2016.11.032
Abstract: Humpback whales, Megaptera novaeangliae, breeding off la Reunion Island (Indian Ocean) undergo large-scale seasonal migrations between summer feeding grounds near Antarctica and their reproductive winter grounds in the Indian Ocean. The main scope of the… read more here.

DOI: 10.1016/j.ygcen.2020.113540
Abstract: Developing a better understanding of the stress response is critical to ensuring the health and sustainability of marine mammal populations. However, accurately measuring and interpreting a stress response in free-ranging, large cetaceans is a nascent… read more here.

DOI: 10.1016/j.yhbeh.2019.104606
Abstract: For most cetacean species, there is little known about how an individual's physiology influences its behaviour. Humpback whales (Megaptera novaeangliae) are a good candidate to examine such links as they have a well-described distribution and… read more here.

DOI: 10.1021/acs.est.1c08636
Abstract: Increasing human activities are altering marine ecosystems, which may have ramifications for predator feeding ecology and, thus, the degree of contaminant exposure. We conducted the first investigation of spatiotemporal trends for nine alternative halogenated flame… read more here.
