Can Mangroves Mitigate Catastrophic Consequences Of Cyclone-Induced Storm Surges?

Massive flooding from storm surges is a major threat to lives and property in low-lying coastal areas during cyclones. The impacts are particularly disastrous when storm surges strike densely populated coastal areas without storm-resilient infrastructure, as the recent storm Idai (March 2019) brutally demonstrated. This category 3 cyclone caused widespread damages and loss of life

Analyzing Growth Response To Climate Change In Two Threatened South American Biomes

Increase in greenhouse gases has caused generalized global warming, mainly from the mid-1970s in the Southern Hemisphere. It is expected that these temperature trends will be intensified at the end of the 21st century, affecting threatened forest ecosystems such as hotspot biomes [1]. Among the most threatened forest ecosystems in South America are the Brazilian Atlantic Forest (BAF)

Small-Scale Or Industrial Plantations? Consumers Must Choose Wisely: Which Oil Palm Production System Can Better Protect Biodiversity?

Tropical rainforest landscapes are threatened by the industrial agricultural expansion, which leads to forest fragmentation and habitat loss. The remaining wildlife is found in low quality and fragmented habitats, leaving numerous species at risk of extinction. Some species even modify their feeding behaviors to survive by relying on crops as their main sources of food.

Biases In Wildlife And Conservation Research

We all have a fascination for large and charismatic animals and normally grow up having a poster of tigers or bears on our wall. Large cats, in particular, are often the symbol of power and strength, due to which they are popular mascots for businesses, sports clubs, or governments. Even the earliest historical records depict

Wood Spirit, An Alert Signal For Plants Under Attack

There is a plant-protecting spirit blowing through the air. If you breathe in carefully now you will smell… wood spirit! Long believed to be a simple by-product of degradation of a plant cell wall, new results show that methanol is a signal that tells surrounding plants to activate their defenses against pathogens and predators. Methanol

A Brown Alga That Controls Stress To Keep Its Shape

To maintain its shape and grow, a cell needs strength. While animals, whose cells are “bare,” rely mainly on their cytoskeleton, organisms like fungi, plants, and algae are constrained by the presence of an envelope, the cell wall, which can be very rigid. Some of these walled organisms develop filaments made of an aligned cell,

5 Examples Of Decomposers In The Environment

Decomposers are organisms which degrade, decay, or breakdown dead organisms, carrying out the process of decomposition. Decomposers are heterotrophic organisms, meaning that they derive their energy from organic substances, in contrast to autotrophic organisms which can generate energy from inorganic sources like sunlight. The term decomposers and detritivores are frequently used interchangeably, but there is

An Invader In The Galapagos: When History And Genetics Merge

The study of genetics deals with a broad range of topics, from the molecules responsible for heredity to the adaptation and evolution of organisms. Within this spectrum is a niche where genetics can turn into a historical science and can be used to test the historical record of a species, thereby better understanding its story.

Rapid Profiling Of Cyanobacterial Communities

Harmful algal blooms (HABs) are a worldwide phenomenon, which have been a cause of concern in aquatic ecosystems since the early 1600s. HABs have massive economic and health impacts such as mortality of aquaculture organisms due to food poisoning, and human illnesses due to exposure or consumption of toxic seafood. In recent years, HABs in
