A shark sanctuary for Tobago

According to the recent study of the Global Status of Reef Sharks, Tobago supports a higher than average number of shark species. Dr Anjani Ganase asks us to take note and institute measures to protect and conserve this diversity. A recent study on the global status of reef sharks has finally been published and confirms that reef sharks have a long history of heavy over exploitation. The study surveyed coral reefs from 58 countries around the world, including 18 in the Caribbean region. These surveys show that about 20 % of the reefs surveyed were devoid of reef shark species; these included the Dominican Republic and Colombia. Areas with lower shark numbers were more commonly associated with greater fishing pressures because of high local human population densities, as well as poor governance and management of shark fishing.  The study also revealed which factors contributed to areas with an above average number of reef sharks. These factors include regulation on the restricted use o

The Plight of the Picoplat

No longer is the song of the Picoplat heard in the wild anywhere in Tobago or Trinidad. Fetching high prices for their singing, they have been trapped to ‘local extinction in the wild.’ Birder photographer Faraaz Abdool asks us to appreciate and protect all the birds of Tobago. This week he looks at the wide-ranging family of tanagers; and asks us to take personal responsibility for their well-being.    The family of tanagers consists of some species that are extremely familiar to most of us. It is quite a large family, comprising approximately 240 species of mostly brightly coloured birds that are emblematic of the jungles of the New World. Some of the most widespread species of birds belong to this family – although many species do not carry the common name of “tanager.” Confusingly, there are other “tanagers” that do not belong to this family. That however, is the subject of another conversation altogether. Red-legged Honeycreepers on a blooming immortelle. Photo courtesy

Deep Sea Mining

As companies move to find valuable resources in more hazardous territory – oil, gas, minerals – Dr Anjani Ganase asks us to pause and reflect on what mining the deep ocean means. As humans seek to exploit our most remote and unknown environments, we need to be mindful of the present threats brought about by decades of ecological damage from continuous production and consumption. Why? As long as we continue to build and advance our technology industry, there will always be a need to mine the elements used in our electronics. The iPhone, and most smart phones, on average are made up of over 75 elements and many have to been mined, including gold for electrical circuits, lithium for batteries, rare earth metals used to make up part of the screen and features in the phone.   However, it is not just phones, most modern electronics, battery systems and alternative energy systems, are built using these earth elements. Over the last fifty years as our technolo

Managing Buccoo Marine Park

T he Buccoo Reef Marine Park was reopened on Monday July 7, 2020   with new regulations. Dr Anjani Ganase talks with marine scientist Shivonne Peters,  Policy Advisor to the Chief Secretary  of the Tobago House of Assembly. about the rules and their enforcement in a renewed attempt to manage human activities and their effects on the life and sustainability of the Buccoo ecosystem and its creatures.   Aerial view of No Man’s Land in the Buccoo Reef Marine Park.

We also learned that if we leave nature alone, it has the potential to heal itself. As humans were kept away from all public and natural spaces, as industries were working on minimal capacity, as our consumption of plastic and food wastage lowered, and the use of cars was reduced, our environments (land and sea)

How animals learn and socialise

Far from being “dumb”, animals do communicate and learn from each other. Dr Anjani Ganase discusses how animals socialize, innovate and learn new behaviors across groups of the species. Intelligence is not a peculiarly human trait and we can learn from other species. In the animal kingdom where parents care for their offspring, they teach them the fundamental lessons for life and the skills to survive. Bird parents teach their young how to fly, orcas, tigers and other predators teach their young to hunt and even monkeys teach their kids how to floss their teeth (with human hair). However, there comes a point where our learning capacity grows beyond genetics and parental care, and this occurs through social learning from peers within a cultural setting. Similar to that of humans, the cultures within the animal kingdom depend on socially learned behavior to benefit groups of individuals with shared advantages within a species population. By observing, cons
