Polar Bear Breeding Begins in the Highlands

Published

on

The conservation charity, the Royal Zoological Society of Scotland (RZSS), announced today that preparations have begun to allow male polar bear Arktos to meet female polar bear Victoria for the first time. This is the latest and most exciting step in our efforts to support the European breeding programme for this at risk species, which is currently listed as Vulnerable on the IUCN Red List of endangered species.

Helping to protect the future of polar bears is not a straightforward task, as it is the loss of sea-ice due to climate change that is the primary threat to the species. Research shows huge uncertainty for the future of polar bears in the wild, with estimates suggesting that the global population could decline by over 30% in just three generations if sea-ice loss continues as projected*. RZSS believes that it has a duty to assist with the establishment of a healthy population of ex-situ animals, not as a substitute for conserving the species in the wild, but to ensure that there will be as broad a range of options for them in the future.

A large 3 by 1.5 by 1.8 metre transportation crate was manoeuvred into position in the male polar bear enclosure on the morning of Friday 19 February and, over the next month or so, eight year old Arktos will be habituated to it. Slowly and steadily, the process will see his keeper’s use positive reinforcement training and his favourite foods to get him used to the new addition to his enclosure. Eventually Arktos will be comfortable enough to enable his keepers at RZSS Highland Wildlife Park to transport him the one mile distance across the Park to Victoria’s enclosure.


Arktos is expected to travel the short distance to begin his courtship with Victoria around mid-March. A great deal of planning went into the development of Victoria’s enclosure in the Highlands and it was specifically designed with breeding in mind. The enclosure is believed to be unique as it offers maximum animal management flexibility with both a large main enclosure and a smaller holding enclosure, in which Arktos will live separate (but adjacent) to Victoria, until their behaviour indicates that signs are right for the full introduction.

RZSS has become known as one of the leading authorities on polar bears, with its enclosure design and husbandry approach being mirrored by other zoological organisations across the world. In total, RZSS Highland Wildlife Park devotes more space to polar bears than any other zoological institution in the world – over four hectares, or 10 acres, in total – and the enclosures features soft grassy areas, natural slopes, ponds and trees.

Modern polar bear husbandry has moved on dramatically and these enclosures are unrecognisable from those that were commonplace even up to ten years ago, where many of the negative stories about polar bears in captivity originate. Following comprehensive research by experts in North America and Europe, the zoo community now has an incredibly thorough understanding of both the husbandry requirements of the species and how to care for and improve cub survival rates.

Douglas Richardson, Head of Living Collections at RZSS Highland Wildlife Park, said: “When we first take Arktos to Victoria, he will live in a separate enclosure adjacent to hers. The two bears will be able to communicate and interact through a secure large fence to start with. We fully expect to see them showing an interest in each other right away.


“As with any introduction of large predators, the process must be approached slowly and carefully, paying close attention to positive behavioural indicators, like vocalisations and body posture.  Whether we wait until Victoria comes into full breeding condition before mixing them together will depend on how they react to each other in the build-up to that key point.

Richardson added: “Polar bear conservation is definitely not simple or easy, but we have an important responsibility. As a conservation body with extensive bear husbandry experience, we truly believe we cannot afford to shy away from the task in hand. If we want to keep all the conservation options on the table for the future of polar bears, we must allow for the idea that a healthy captive population may provide a solution to the species’ plight.

“The birth and rearing of polar bears cubs will be of real value to the overarching breeding programme. As well as helping to highlight the plight of polar bears in the wild, any cubs born in the foreseeable future will remain within the vital safety net of the captive breeding programme. The shrinking polar ice-cap and shortening polar ice season has pitched the species to the forefront of conservation concerns.

Richardson added: “In an ideal world, conservation would happen first and foremost in the wild, but unfortunately this is not the scenario we are dealing with. The next best thing is a combined approach, with in-situ and ex-situ work taking place simultaneously and in a joined up manner. The zoo community has a duty of care to help this species survive and collectively our work is helping to preserve as varied a mix of genes as possible; it will also maintain the option of being able to return animals to the wild at some point in the future. Whilst Victoria’s cubs will never go back into the wild themselves, further down the line her offspring may well play a key role in restoring or augmenting populations in the Arctic.”

Are the UK Governments Plans for the Energy Sector Smart?

Published

on

The revolution in the energy sector marches on, wind turbines and solar panels are harnessing more renewable energy than ever before – so where is it all leading?

The UK government have recently announced plans to modernise the way we produce, store and use electricity. And, if realised, the plans could be just the thing to bring the energy sector in line with 21st century technology and ideologies.


Central to the plans is an initiative that will see smart meters installed in homes and businesses the length and breadth of the country – and their aim? To create an environment where electricity can be managed more efficiently.

The news has prompted some speculation about how energy suppliers will react and many are predicting a price war. This could benefit consumers of electricity and investors, many of whom may be looking to make a profit by trading energy company shares online using platforms such as Oanda – but the potential for good news doesn’t end there.

Introducing New Technology

The plan, titled Smart Systems and Flexibility is being rolled out in the hope that it will have a positive impact in three core areas.

  • To offer consumers greater control by making smart meters available for all homes and businesses by 2020. Energy users will be able to monitor, control and record the amount of energy they use.
  • Incentivise energy suppliers to change the manner in which they buy electricity, to offer more smart tariffs and more off-peak periods for energy consumption.
  • Introduce new standards for electrical appliances – it is hoped that the new wave of appliances will recognise when electricity is at its cheapest and at its most expensive and respond accordingly.

How the Plans Will Affect Solar Energy

Around 7 million houses in the UK have solar panels and the government say that their plan will benefit them as they will be able to store electricity on batteries. The stored energy can then be used by the household and excess energy can be exported to the national grid – in this instance lower tariffs or even payment for the excess energy will bring down annual costs significantly.


The rate of return on energy exported to the national grid is currently between 6% and 10%, but there are many variables to take into account, such as, the cost of battery storage and light levels. Still, those with state-of-the-art solar electricity systems could end up with an annual profit after selling their excess energy.

The Internet of Things

Much of what the plans set out to achieve are linked to the now ubiquitous “internet of things” – where, for example, appliances and heating systems are connected to the internet in order to make them function more smartly.

Companies like Hive have already made great inroads into this type of technology, but the road that the government plans are heading down, will, potentially, go much further -blockchain technology looms and has already proved to be a game changer in the world of currency.

Blockchain Technology

It has already been suggested that the peer to peer selling of energy and exporting it to the national grid may eventually be done using blockchain technology.

“The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.”

Don and Alex Tapscott, Blockchain Revolution (2016)

The upshot of the government’s plans for the revolution of the energy sector, is that technology will play an indelible role in making it more efficient, more flexible and ultimately more sustainable.

4 Case Studies on the Benefits of Solar Energy

Published

By

Demand for solar energy is growing at a surprising rate. New figures from SolarPower Europe show that solar energy production has risen 50% since the summer of 2016.

However, many people are still skeptical of the benefits of solar energy.Does it actually make a significant reduction in our carbon footprint? Is it actually cost-effective for the company over the long-run?


A number of case studies have been conducted, which indicate solar energy can be enormously beneficial. Here are some of the most compelling studies on the subject.

1.     Boulder Nissan

When you think of companies that leverage solar power, car dealerships probably aren’t the first ones that come to mind. However, Boulder Nissan is highly committed to promoting green energy. They worked with Independent Power Systems to setup a number of solar cells. Here were the results:

  • Boulder Nissan has reduced coal generated electricity by 65%.
  • They are on track to run on 100% renewable energy within the next 13 years.
  • Boulder Nissan reduced CO2 emissions by 416,000 lbs. within the first year after installing their solar panels.

This is one of the most impressive solar energy case studies a small business has published in recent years. It shows that even small companies in rural communities can make a major difference by adapting solar energy.

2.     Valley Electric Association

In 2015, the Valley Electric Association (VEA) created an 80-acre solar garden. Before retiring from the legislature, U.S. Senate Minority Leader Harry Reid praised the new project as a way to make the state more energy dependent and reduce our carbon footprint.


“This facility will provide its customers with the opportunity to purchase 100 percent of their electricity from clean energy produced in Nevada,” Reid told reporters with the Pahrump Valley Times. “That’s a step forward for the Silver State, but it also proves that utilities can work with customers to provide clean renewable energy that they demand.”

The solar energy that VEA produced was drastically higher than anyone would have predicted. SolarWorld estimates that the solar garden created 32,680,000 kwh every year, which was enough to power nearly 4,000 homes.

This was a major undertaking for a purple state, which may inspire their peers throughout the Midwest to develop solar gardens of their own. It will reduce dependency on the electric grid, which is a problem for many remote states in the central part of the country.

3.     Las Vegas Casinos

A number of Las Vegas casinos have started investing in solar panels over the last couple of years. The Guardian reports that many of these casinos have cut costs considerably. Some of them are even selling the energy back to the grid.

“It’s no accident that we put the array on top of a conference center. This is good business for us,” Cindy Ortega, chief sustainability officer at MGM Resorts told Guardian reporters. “We are looking at leaving the power system, and one of the reasons for that is we can procure more renewable energy on the open market.”

There have been many benefits for casinos using solar energy. They are some of the most energy-intensive institutions in the world, so this has helped them become much more cost-effective. It also helps minimize disruptions to their customers learning online keno strategies in the event of any problems with the electric grid.

4.     Boston College

Boston College has been committed to many green initiatives over the years. A group of researchers experimented with solar cells on different parts of the campus to see where they could produce the most electricity. They discovered that the best locationwas at St. Clement’sHall. The solar cells there dramatically. It would also reduce CO2 emissions by 521,702 lbs. a year and be enough to save 10,869 trees.

Boston College is exploring new ways to expand their usage of solar cells. They may be able to invest in more effective solar panels that can generate far more solar energy.
