Off the west coast of Peru, seabirds deposit thick layers of guano that accumulates on the ground because of the lack of rain. Guano has historically played a key role in agriculture worldwide because it is rich in plant nutrients such as nitrogen READ MORE
Biological classification arranges taxa according to their degree of relationship; several species may be grouped in a genus, several genera may be grouped in a family, etc. Higher-level systematics in amphibians is relatively stable and taxonomic novelties above the species level are rare.

For many years, morphology-based classification has served us so well, and still forms a basis of what we are viewing the biological world today. Scientists have described morphological similarities and differences of animals and plants for centuries. Their insights into morphological READ MORE
Mitochondrial DNA studies shows the occurrence of three well-defined groups of pipefish populations – which independently evolved in a Pleistocene scenario – for Syngnathus abaster in the western Mediterranean and Adriatic Seas. We marvel at the diversity of morphological variability READ MORE
Ever since the nineteenth century scientists have recognised that some regions contain more species than others, and that the tropics are richer in biodiversity than temperate regions. But why are there more species in the tropics? A new study published on 28 January in READ MORE
“Ray” or “Skate” is the common name under which a number of different species of rays (cousins to sharks) fished from the Northeast Atlantic are commonly sold in supermarkets in Western Europe. They are also traditionally sold as ‘wings’, where READ MORE
A James Cook University-National Geographic expedition to Cape Melville in north-east Australia has found three vertebrate species new to science and isolated for millions of years—a bizarre looking leaf-tail gecko, a golden-coloured skink and a boulder-dwelling frog that doesn’t need READ MORE
The ancestor of snakes and lizards likely gave birth to live young, rather than laid eggs, and over time species have switched back and forth in their preferred reproductive mode, according to our new research, published in print in Ecology Letters Dec. 17. This is READ MORE
Seadragons are known for their elaborate appendages that help them blend in with their kelp and algae habitats. But an evolutionary tree based on molecular data showed that one of the three species was a faker. The two southern species, the leafy READ MORE
Sea Star Meltdown A shocking trend has emerged in the world’s premiere ecosystem for sea star biodiversity. The coastline of British Columbia has seen extensive “melting” in its sea star populations, particularly among sunflower sea stars (P. helianthoides.) Divers report READ MORE
