New article on lobomycosis-like disease in bottlenose dolphins in Belize and Mexico
by Eric Ramos 22 Mar '18

22 Mar '18

My co-authors and I are pleased to announce the recent publication of our article: Ramos EA, Castelblanco-Martínez DN, Garcia J, Rojas Arias J and others (2018) Lobomycosis-like disease in common bottlenose dolphinsTursiops truncatus from Belize and Mexico: bridging the gap between the Americas. Diseases of Aquatic Organisms 128:1-12.https://doi.org/10.3354/dao03206 AbstractLobomycosis and lobomycosis-like diseases (LLD) (also: paracoccidioidomycosis) are chronic cutaneous infections that affect Delphinidae in tropical and subtropical regions worldwide.In the Americas, these diseases have been relatively well-described, but gaps still exist in our understanding of their distribution across the continent. Here we report on LLD affecting inshore bottlenose dolphins Tursiops truncatus from the Caribbean waters of Belize and from the eastern tropical Pacific Ocean off the southwestern coast of Mexico. Photo-identification and catalog data gathered between 1992 and 2017 for 371 and 41 individuals, respectively from Belize and Mexico, were examined for the presence of LLD. In Belize, 5 free-ranging and 1 stranded dolphin were found positive in at least 3 communities with the highest prevalence in the south. In Guerrero, Mexico, 4 inshore bottlenose dolphins sighted in 2014−2017 were affected by LLD. These data highlight the need for histological and molecular studies to confirm the etiological agent. Additionally, we document a single case of LLD in an adult Atlantic spotted dolphin Stenella frontalis in southern Belize, the first report in this species. The role of environmental and anthropogenic factors in the occurrence, severity, and epidemiology of LLD in South and Central America requires further investigation.

New paper - Refining estimates of availability bias to improve assessments of the conservation status of an endangered dolphin
by Federico Sucunza 22 Mar '18

22 Mar '18

Dear colleagues, My co-authors and I are pleased to announce our new publication: Sucunza F, Danilewicz D, Cremer M, Andriolo A, Zerbini AN (2018) Refining estimates of availability bias to improve assessments of the conservation status of an endangered dolphin. Abstract: Estimation of visibility bias is critical to accurately compute abundance of wild populations. The franciscana, Pontoporia blainvillei, is considered the most threatened small cetacean in the southwestern Atlantic Ocean. Aerial surveys are considered the most effective method to estimate abundance of this species, but many existing estimates have been considered unreliable because they lack proper estimation of correction factors for visibility bias. In this study, helicopter surveys were conducted to determine surfacing-diving intervals of franciscanas and to estimate availability for aerial platforms. Fifteen hours were flown and 101 groups of 1 to 7 franciscanas were monitored, resulting in a sample of 248 surface-dive cycles. The mean surfacing interval and diving interval times were 16.10 seconds (SE=9.74) and 39.77 seconds (SE=29.06), respectively. Availability was estimated at 0.39 (SE=0.01), a value 16–46% greater than estimates computed from diving parameters obtained from boats or from land. Generalized mixed-effects models were used to investigate the influence of biological and environmental predictors on the proportion of time franciscana groups are visually available to be seen from an aerial platform. These models revealed that group size was the main factor influencing the proportion at surface. The use of negatively biased estimates of availability results in overestimation of abundance, leads to overly optimistic assessments of extinction probabilities and to potentially ineffective management actions. This study demonstrates that estimates of availability must be computed from suitable platforms to ensure proper conservation decisions are implemented to protect threatened species such as the franciscana.

Citzen Science in Brazil
by Liliane Lodi 22 Mar '18

22 Mar '18

Dear Colleagues, On behalf of my co-author, I'm pleased to announce a publication: Lodi, L.; Tardin, R. 2018. Citizen science contributes to the understanding of the occurrence and distribution of cetaceans in southeastern Brazil - A case study. Ocean and Coastal Management. 158 : 45-55. <https://doi.org/10.1016/j.ocecoaman.2018.03.029> https://doi.org/10.1016/j.ocecoaman.2018.03.029 ABSTRACT Citizen Science projects involve ordinary people in scientific research, providing new insights and perspectives. Interested members of the public may contribute valuable information as they learn about wildlife in their local communities. This study investigates the spatiotemporal occurrence and distribution of cetaceans off the coast of Rio de Janeiro, Brazil, based on data obtained by citizen scientists (opportunistic observations - 2013/2016) and by cetacean researchers (dedicated observations - 2011/2016). The citizen scientists recorded 178 sightings of eight cetacean species along the whole Rio de Janeiro coast. Boat surveys (N= 118) were conducted by the authors in two Marine Protected Areas (MPA) and adjacent waters, resulting in a total of 77 records of four cetaceans species. Within the same area surveyed, citizen scientists contributed 98 reports of these four species. There was a high degree of information overlap, although the citizen scientists also expanded the database on the occurrence and distribution of cetaceans. The citizen scientists also confirmed the occurrence in the study area of four additional cetacean species, not recorded during the surveys. Opportunistic observations obtained from citizen scientists are thus a fundamentally important complementary tool for this type of investigation. The distribution records of the two datasets were also broadly compatible, in particular for the inshore sightings and the seasonal distribution of three of the four principal species. Overall, then, the data provided by from citizen scientists off the coast of Rio de Janeiro were validated by the boat surveys, which focused specifically on the area of the MPAs and adjacencies. The information provided by the combined dataset provides important insights for the creation of a buffer zone, which provide an additional layer of protection for the region's marine biota.

New publication on heat flux in Florida manatees
by Nicola Erdsack 22 Mar '18

22 Mar '18

My co-authors and I are pleased to announce our recent publication: Erdsack N, McCully Phillips SR, Rommel SA, Pabst DA, McLellan WA, Reynolds JE, III (2018) Heat flux in manatees: an individual matter and a novel approach to assess and monitor the thermal state of Florida manatees (/Trichechus manatus latirostris/). Journal of Comparative Physiology B (online first). doi:10.1007/s00360-018-1152-7 Abstract: Florida manatees (/Trichechus manatus latirostris/) possess an unusual suite of adaptations to accommodate both a fully aquatic lifestyle and an herbivorous diet, including a low metabolic rate and a very limited thermoneutral zone. Their relatively high lower critical temperature of around 20 °C suggests strong sensitivity to cold, thereby limiting their distribution to tropical and subtropical waters. “Cold stress syndrome” affects and kills Florida manatees every year during intense or prolonged cold weather, posing one of the major threats to manatees. However, knowledge regarding manatee thermoregulation is sparse, but essential for effective conservation and management of this threatened species. We measured heat flux in two captive Florida manatees at multiple times of the year, at 41 sites distributed across the entire body surface of each manatee. Heat flux differed significantly between individuals, and among body sites and times of the year. The pectoral flippers and axillae were identified as areas with highest heat exchange. Despite exposure to constant water temperature throughout the year, the manatees in this study had significantly lower heat flux in winter than in summer. We used the measured heat flux values to calculate total heat dissipation in individual manatees. The values estimated this way correspond well with the low metabolic rates estimated in previous studies, confirming the reliability of our novel approach. Our method provides simple and useful options for enhancing manatee welfare by monitoring the animals’ thermal state during potentially stressful activities such as during medical treatment, capture restraints and transportation.

Dear Marmamers, We are seeking 1 field assistant for the Cedar Key Dolphin Project 2018 field season this upcoming summer, between mid-May and mid/late-August (up to 13 weeks). The field season will be focused on gathering acoustic and behavioral data during specialized foraging tactics as part of a Masters candidate project through the University of Massachusetts. Research will take place in Cedar Key, Florida, 3 hours north of Tampa and 60 miles west of Gainesville. Preference will be given to applicants who can stay for the duration of the season. The assistant will be expected to work on a boat 6 to 7 days per week, for up to 10 hours at a time. Typical weather conditions in summer include 95 degree heat, very high humidity, and no breezes. When the weather does not permit fieldwork, work will consist of photo matching, processing, and data entry. This is a volunteer position. Assistants will be responsible for arranging their own transportation to Florida, but housing and food will be covered while on-site. Prior field experience with photo-ID and boat handling is preferred, but not required. Those with no experience should demonstrate their willingness to learn. Since we will be living and working closely, applicants must work well in teams and have a positive attitude. Please send an email of inquiry to master's candidate Rebecca Hamilton (rhamilton(a)umassd.edu) with the subject line "Field assistant for 2018". A more in-depth description of the position and its requirements will be emailed out--at that time, candidates who are still interested will be asked to provide their CV, cover letter, and contact information for 2 references.
