Relationships between various organisms stem to achieve an ultimate objective - survival. In mutualistic relationships, all involved in the relationship help each other survive, whereas in parasitic relationships, only one of those have an upper hand. But in spite of this chaos, how does nature maintain a balance? In a new study, scientists have studied examples of such relationships between termites and fungi - both mutualistic and parasitic - and have uncovered some interesting strategies adopted by these fungi to survive and thrive.

Nature has bestowed each organism the ability to adapt and evolve with time and each such adaptations strengthens the ability of the organism to flourish. The story of carpenter bees, a close relative of honey bees and bumblebees, is no different. In a research study, scientist have observed how different adaptations of males of three different species of carpenter bees influence their ability to find a mate.

A team of scientists from Centre for Ecological Sciences (CES) at the Indian Institute of Science (IISc) have discovered a new species of plant – Reissantia (Celastraceae). Members belonging to Reissantia family are usually found in Old World tropics of Africa and the Indo- Malaya regions.  The plants are found as a climbing, scandent or erect shrub and are characterized by small flowers. The discovery is the latest in a string of new species being discovered in the Western Ghats, including the Narrow Mouthed Laterite Frog and the Karaavali Skittering Frog.

The National Rural Employment Guarantee Act 2005, which was later renamed to Mahatma Gandhi National Rural Employment Guarantee Act (MNREGA) is a labour law passed to ensure employment for the rural population. The act provides 100 days of guaranteed wages to an unskilled manual labourer, helping them cope with the unemployment.

Forests play a critical role in sustaining biodiversity on the planet, including humans. They once provided food and shelter when we were hunter-gatherers. Today, our relationship with forests is at a new level. We derive most of our energy resources from forests in the form of wood and coal. What are some of the implications of this relationship and how fragile is it getting in the future? On this International Day of Forests, here is an introspection of the same.

The 3rd of March every year was declared World Wildlife Day by the United Nations General Assembly to mark the signing of the landmark Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1973. Aimed at celebrating and raising awareness of the world’s wild animals and plants, the day is a chance for us to think about the major threats to wildlife including habitat change, over-exploitation and illicit trafficking.

“Where are house sparrows these days? They have just become extinct!”, is a common rhetoric we hear these days in the cities. Yet, it is impossible to scientifically assert that they are dwindling in numbers, since there has not been any systematic observation or data gathered about them.

The case of the ‘vanishing’ sparrows in cities like Bengaluru throws light on an important issue associated with biodiversity – the lack of data. Old-timers across the city are able to recall a time when sparrows were ubiquitous and also observe them diminish by the day. To add to this, there has been significant drop in the tree cover and the number of insects and birds in our neighbourhood. But, to objectively answer any questions like the change in the numbers of any species, the total number of species present and the effects of a vanishing species on an ecosystem, rigorous observations, documentation and research is a necessity. In the lack of these, it is simply impossible to infer or conclude that there has been a change, let alone the decline or disappearance of certain species. This drives us to reconsider the strategies of understanding biodiversity.
