Taking a molecular approach to conserving freshwater biodiversity

09.11.2015

Molecular ecologists have a key role to play in setting priorities for the conservation of aquatic biodiversity, according to a recent review paper published in the Pertanika Journal of Tropical Agricultural Sciences.

By applying DNA sequencing and related tools, molecular ecologists can collaborate with other ecologists, especially in the fields of species distribution modelling and conservation planning, argues the paper’s author, Jane Hughes, of the Australian Rivers Institute.

“This approach will help to prioritise conservation actions for the best possible outcomes.”

As the world’s population grows, human water needs are growing accordingly, reducing the amount of water available for sustaining freshwater biodiversity. This situation will likely worsen in areas where rainfall decreases as a result of global climate change.

Growing human demand for water will affect biodiversity primarily by increasing the number of dams, which already number over one million globally, as well as the extraction of water for agriculture and aquaculture. “Already, declines in freshwater biodiversity are far greater than in terrestrial systems [i.e. ecosystems present on land],” notes Dr Hughes.

For competing needs to be managed, we need accurate and efficient ways to assess our biodiversity, she stresses. “Currently, species are going extinct more quickly than we can recognise them.”

We also need accurate and efficient ways to assess the current and historical connectivity among populations, as well as the need for freshwater species to maintain connectivity with other habitats such as the floodplain or the estuary, adds Dr Hughes. “Finally, we need to develop methods for prioritising which rivers, streams or reaches should best be preserved or protected in order to maximise protection of biodiversity.”

Molecular ecologists can contribute to these challenges in many ways, says Dr Hughes. In her paper, she discusses recent advances in the assessment of biodiversity, methods for assessing connectivity among aquatic populations, how to combine molecular approaches with other methods to understand migration patterns, and future options that could improve our ability to conserve freshwater biodiversity.

“A multidisciplinary approach that incorporates new technological approaches in acquisition of molecular data is the best way forward for our aquatic biodiversity,” she concludes.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
