The phenomenon made headlines for several weeks as there was considerable speculation as to the possible causes and concern about the implications of this situation for the beluga&#8217;s recovery.<\/p>\n<p>In 2013, scientific teams working on different aspects of this population all stepped up their efforts to update their data and conduct further analysis. Some data series cover over 30 years.<\/p>\n<p>These teams had agreed to meet in the fall of 2013 to assess the situation. The conclusion reached by the end of this meeting is alarming: the analysis did not allow researchers to pinpoint the cause of the 2012 mortalities, but it did reveal a more fundamental problem: the population, which had previously been considered to be stable, had been declining since the beginning of the 2000s. This conclusion was the object of a <a href=\"http:\/\/pp.baleinesendirect.org\/les-belugas-du-saint-laurent-sont-en-declin\/#avis\">Science Advisory Report<\/a>.

Rising water temperatures, reduced ice cover in the winter and changes in the abundance and distribution of prey all represent unfavourable conditions for this already fragile population. The rapid rise of a new class of contaminants through the early 2000s and the increase in maritime traffic and disturbance in the Upper Estuary further contribute to the degradation of beluga habitat.<\/p>\n<p><a name=\"avenir\"><\/a><\/p>\n<h3>An Uncertain Future<\/h3>\n<p>The picture is thus bleak for the St. Lawrence beluga. The increase in newborn mortalities remains unexplained, but researchers are especially concerned about the impact that these deaths will have on the population&#8217;s trajectory. These &#8220;absent&#8221; newborns will surely translate into &#8220;absent&#8221; juveniles and adults in coming years, which may accelerate the decline observed over the last decade. Further, it is expected that climate change will accelerate, progressively eroding the conditions for the St. Lawrence belugas.<\/p>\n<p>The enigmatic beluga was the catalyst behind a very broad mobilization to clean up and protect the St. Lawrence in the early 1980s. Decontamination, stricter regulations on industrial waste, creation of the Saguenay-St. Lawrence Marine Park, banning of hydrocarbon exploration and drilling activities in the Estuary&#8230; many initiatives have their origins in the alarm sounded by the beluga on the state of the rich yet fragile St. Lawrence. Today, the St. Lawrence and belugas face new pressures. What does the future look like for the St. Lawrence beluga? Can we save these canaries of the sea? Three St. Lawrence beluga specialists share their views.<\/p>\n<p><a name=\"chercheurs\"><\/a><\/p>\n<h3>Scientists Take the Floor<\/h3>\n<p><a href=\"http:\/\/baleinesendirect.org\/en\/scientific-exploration\/research-in-quebec\/stephane-lair\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>St\u00e9phane Lair<\/strong><\/a><strong>, veterinarian for the beluga necropsy program:<\/strong><br \/>\n<a href=\"http:\/\/baleinesendirect.org\/wp-content\/uploads\/2015\/05\/LairStephane.jpg\"><img decoding=\"async\" class=\"alignleft size-full wp-image-9812\" src=\"http:\/\/baleinesendirect.org\/wp-content\/uploads\/2015\/05\/LairStephane.jpg\" alt=\"LairStephane\" \/><\/a>&#8220;In the 1970s, scientists revealed serious problems related to chemical contaminants such as PAHs and PCBs, which led to regulatory changes. We&#8217;re beginning to see the benefits of these measures: some of these contaminants, which were present in record concentrations in belugas in the 1980s, have since declined. Cancers, which were the main cause of mortality in adults in the 1980s and 90s, have also become less frequent. No beluga born after 1971 has died from cancer. But at the same time, the population is suffering from other problems, most likely related to climate change.

The number of carcasses found annually has remained stable at about 15 a year. The number of newborns found dead varied between 0 and 3 until 2007, and was exceptionally high in 2008 (8), 2010 (8) and 2012 (16). The average age of females found dead has been falling since the 2000s and, since 2010, more females have been reported as dying from complications arising during calving.<\/li>\n<li>Between 1988 and 2009, eight <strong>aerial photographic surveys<\/strong> were conducted in an effort to estimate the number of belugas. The 2009 estimate is the lowest of the series, though no trend can be confirmed as the number of censuses is too low and the variations are too great. A second series of aerial surveys \u2013 visual surveys this time \u2013 was performed between 2001 and 2009. The 2009 count is also the lowest of the lot, but once again no trend can be confirmed with this tool as the period covered is too short and its accuracy is too poor.<\/li>\n<li>These aerial surveys do however detect a decline in the proportion of young in the population (first-year animals): this ratio went from 15.1-17.8% in the 1990s to 3.2-8.4% in the 2000s.<\/li>\n<li>A <strong>mathematical model<\/strong> was developed on the basis of data collected from the aerial surveys and the carcass recovery program. The model suggests that the population was likely stable or slightly increasing up until the early 2000s, and that it has been declining ever since. The model estimates the size of the population in 2012 at 889 belugas.<\/li>\n<li>The model also suggests that the beluga population has been experiencing a period of instability since the early 2000s, notably with a decline in the proportion of juveniles and newborns in the population and highly fluctuating newborn mortalities.<\/li>\n<li>The conclusions of this modelling exercise concord with the observations of the <strong>annual beluga census program using photo-identification<\/strong> (1989-2012). This independent data set reveals the same trends as the model in terms of the evolution of the proportion of young and the production of newborns.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul><p><strong>Searching for explanations<\/strong><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Analysis of stable isotope ratios measured in carcasses between 1988 and 2012 shows that there has been a change in the source of carbon (and thus probably in their diets) in belugas since 2003.<\/li>\n<li>An analysis comprising 28 environmental indices monitored between 1990 and 2012 shows that the system has undergone significant changes in the past few years, with a decline in the biomass of certain fish species, below-normal ice conditions in winter and above-normal water temperatures.<\/li>\n<li>These belugas are amongst the most heavily contaminated marine mammals in the world. Certain contaminants have been diminishing in the past decade or so (e.g. PCBs, DDT), while polybrominated compounds (PBDE) increased exponentially in the 1990s. PBDEs might have an impact on the survival of young or the ability of females to care for them.<\/li>\n<li>Maritime traffic associated with tourism and recreational boating peaks in July-August, at the same time as the beluga&#8217;s calving season. This traffic increased between 2003 and 2012 in certain sectors, including those used by females and young.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul><p><strong>Another look at newborn mortalities<\/strong><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>In 2008, the newborn mortalities (8) were associated with a bloom of the toxic alga <em>Alexandrium tamarense<\/em> in the Estuary. Numerous other marine mammals had experienced unusual mortalities that summer and chemical and pathological examinations concluded that saxitoxin had played a role, whether alone or in conjunction with other unfavourable factors.<\/li>\n<li>In 2010 and 2012, unknown factors reduced young belugas&#8217; chances of survival. This period coincides with a period of even more pronounced changes in terms of reduced ice cover in winter and higher water temperatures.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul><p><strong>Conclusions<\/strong><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>The model suggests that the population of St. Lawrence belugas has been declining since the early 2000s. This decline corresponds to a period of unfavourable environmental conditions, high levels of polybrominated contaminants (PBDE), increased exposure to noise and maritime traffic and a toxic algal bloom.<\/li>\n<li>The St. Lawrence population&#8217;s ecosystem is undergoing tremendous changes that could have an impact on the beluga as they intensify. Even if little can be done in the short term to counteract these changes in the ecosystem, we can focus our efforts on reducing the impacts of our activities, such as disturbance to sensitive areas, chemical contamination, habitat loss or competition with fisheries.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><a name=\"dossier\"><\/a><\/p>\n<h3>Related Dossier<\/h3>\n<p>An oil port project in Cacouna threatens a beluga nursery<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><a href=\"http:\/\/pp.baleinesendirect.org\/projet-de-port-petrolier-a-cacouna-un-danger-pour-les-belugas\/\" target=\"_blank\" rel=\"noopener noreferrer\">Projet de port p\u00e9trolier \u00e0 Cacouna: un danger pour les b\u00e9lugas (presently in French only)<\/a><\/li>\n<\/ul>\n<\/li>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><a href=\"http:\/\/baleinesendirect.org\/lhabitat-essentiel-du-beluga-du-saint-laurent-est-a-proteger-durgence\/\" target=\"_blank\" rel=\"noopener noreferrer\">L\u2019habitat essentiel du b\u00e9luga du Saint-Laurent est \u00e0 prot\u00e9ger d\u2019urgence (presently in French only)<\/a><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><a name=\"medias\"><\/a><\/p>\n<h3>In the Media<\/h3>\n<p><a name=\"recent\"><\/a><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><a href=\"http:\/\/ici.radio-canada.ca\/nouvelles\/national\/2016\/02\/08\/001-belugas-quebec-morts-deces-fleuve-meres-bebes-autopsie.shtml\" target=\"_blank\" rel=\"noopener noreferrer\">Les d\u00e9c\u00e8s de m\u00e8res et de b\u00e9b\u00e9s b\u00e9lugas sont anormalement \u00e9lev\u00e9s<\/a> (Radio-Canada, Thomas Gerbet, 8 f\u00e9vrier 2016)<\/li>\n<li><a href=\"http:\/\/www.cbc.ca\/news\/canada\/montreal\/quebec-beluga-population-1.3438691\" target=\"_blank\" rel=\"noopener noreferrer\">St. Lawrence belugas: Researchers point to &#8216;worrisome&#8217;
