Aleem Mohamed appeared on Thursday before Wales Magistrate Dylon Bess on a charge detailing, that on June 12, 2018, he cuffed and kicked his daughter after she objected to his drunken behaviour.Mohamed admitted to assaulting his pregnant daughter Bibi Mohamed at the family home at La Parfaite Harmonie, West Bank Demerara on the day in question. He told the court that he “didn’t like the way” his daughter was speaking to him, but the woman said that her father would always swear and behave disorderly when drunk; and she noted that his behaviour is very stressful.Mohamed was placed on a bond to keep to peace, and he promised the magistrate not to drink again. He has been advised that if, at any time within the next six months, he is caught consuming alcohol, he would be sent to prison.

Study shows global warming likely to alter bat echolocation abilitiesStudy shows global warming likely to alter bat echolocation abilities
Journal information: Journal of the Royal Society Interface Large moths need to hear better Bats, as most are aware, make their way through the air using echolocation—they emit sounds and listen as the sounds are bounced back to them after hitting something. This ability not only helps them avoid running into things in dark, but it’s the means by which they identify and catch prey. In this new effort, the researchers found that changes in air temperature of just a few degrees could have a profound impact on the echolocation abilities of bats around the world.Attenuation—the tendency of sound to lose volume and clarity as it moves through the air (or other materials) is impacted by a variety of factors, such as humidity, wind and of course heat—low frequency sounds are less impacted than are high frequency sounds. This means that bats that live in temperate climates such as North America or Europe (who use high frequency chirps) are likely to face more challenges than low frequency chirping bats living in the tropics, as global temperature rise.Of course nothing in nature is as simple as that, other factors have an impact on survival of species as well, and global warming is almost certain to cause environmental impacts that no one foresaw. But, what is clear from this new study is that some bats are likely to be winners, and some losers, because of where they live. Those that live in temperate climates but who use low frequencies, for example, might find the hunting getting easier. Others who are slow to adapt, on the other hand, may find the added stress of having to chirp louder, lower or more often, too much to bare leaving them with too little energy to mate.An associated finding with this study is that it highlights the fact that the more the impact of global warming is studied, the more we discover just how far and wide the impact will be felt, both on a global scale, and within simple communities, such as those occupied by bats.

Here, we present a functional link between rising temperature and the prey detection ability of echolocating bats. The maximum distance for echo-based prey detection is physically determined by sound attenuation. Attenuation is more pronounced for high-frequency sound, such as echolocation, and is a nonlinear function of both call frequency and ambient temperature. Hence, the prey detection ability, and thus possibly the foraging efficiency, of echolocating bats and susceptible to rising temperatures through climate change. Using present-day climate data and projected temperature rises, we modelled this effect for the entire range of bat call frequencies and climate zones around the globe. We show that depending on call frequency, the prey detection volume of bats will either decrease or increase: species calling above a crossover frequency will lose and species emitting lower frequencies will gain prey detection volume, with crossover frequency and magnitude depending on the local climatic conditions. Within local species assemblages, this may cause a change in community composition. Global warming can thus directly affect the prey detection ability of individual bats and indirectly their interspecific interactions with competitors and prey. This document is subject to copyright.

In their study published in The Journal of the Royal Society Interface, the group explains how they found that warming temperatures are likely to impact attenuation of bat chirps in various ways.
