Introduction
I'm currently working on the social structure of long finned pilot whales off Cape Breton. I'm integrating behavioural and molecular data to achieve a clearer picture of this species social structure. I'm passionate about sharing science with a wider audience, either my own research or other areas. Science outreach and environmental education are very important to me, and I would enjoy working in those areas in the future.

Article
Full-text available
Cetacean social structures include fluid and stable elements. Long-finned pilot whales (Globicephala melas) live in units that interact forming labile groups. In this study conducted off Cape Breton Island, between 1998–2011, we confirm unit membership predicts associations between individuals. We determine how units are structured and interact. We...
Thesis
Full-text available
The long-finned pilot whale (Globicephala melas) is an intensely social species. I describe the social structure of the population off Cape Breton, Nova Scotia, using 12 years of individual association and behavioural data, adding molecular analyses and investigating alloparental care. Previous studies on the social structure of the species point t...

Alloparental care happens when a calf is cared for by an adult that is not their parent. Although alloparental care is common in social mammals, its prevalence is difficult to assess in cetaceans, and has not been studied in Globicephala melas. A population off Cape Breton, Nova Scotia, has been studied from whale-watching vessels since 1998, durin...
Conference Paper
The long-finned pilot whales that summer off Cape Breton have been studied from whalewatching vessels since 1998, during July and August each year. Photographic data was collected for each group encounter, allowing us to identify individuals. Units are comprised of key individuals and their close companions (CCs). Key individuals are identified as...

A long-term photo-identification study on long-finned pilot whales (Globicephala melas) off Pleasant Bay, Nova Scotia, Canada, expanded to include remote biopsy sampling via crossbow in 2010 to 2012. The present study aims to investigate any negative effects biopsy sampling may have on the animals. During sampling, each shot was videotaped for late...
Article
Full-text available
The resident population of common bottlenose dolphins (Tursiops truncatus) in the Sado Estuary, Portugal, has been declining at least during the past three decades. A complete photographic census produced a current count of 24 animals—19 adults, three subadults and two calves. It appears to be phylopatric and essentially closed, but given the likel...
Presentation
A comunidade de golfinhos-roazes (Tursiops truncatus) residente no Estuário do Sado tem vindo a decair nas últimas duas décadas, encontrando-se agora com 26 indivíduos. Esta diminuição aliada à sua dieta generalista e à alta produtividade do seu habitat permitiu alterações na estrutura social e dos grupos. Entre 2007 e 2008, o tamanho médio de grup...
Conference Paper
Full-text available
The Sado estuary accommodates the only resident bottlenose dolphin resident population in mainland Portugal (and one of the few in Europe) which is small enough for monitoring using complete censuses. Its numbers have declined in the past decades, reaching a current number of 26 individuals, the minimum on record. The majority of dolphins in the po...
