Study indicates decline in seabed-dwelling fish in the Mediterranean

Using data gathered by satellites, scientists have monitored changes in fishing activity around Italy in the Mediterranean Sea for the period 2007-2010. From this, they developed new ecological indicators that gave a more detailed pattern of fishing activity in the Italian seas. In addition, the new indicators suggest that fish stocks on the seabed around Italy are continuing to decline.

Predicting fish species’ decline before it’s too late

An early warning system to predict the overfishing of individual species, far in advance of severe population decline, has been developed by researchers. The ‘eventual threat index’ was applied by the researchers to historical data on tuna and billfish populations, and accurately predicted their current declines as early as the 1950s.

Modern agriculture and land use behind the decline in bees

Estonian research has identified land use practices and agrochemical use as the main pressures that are causing a decline in pollinating insects in Europe, such as bees and butterflies. It calls for increased funds for agri-environment measures from the Common Agricultural Policy (CAP) to help tackle pollinator loss.

Soil quality and crop yield decline under plastic tunnels

Recent research in Italy has suggested that soil quality deteriorates over time when intensively farmed under plastic tunnels. The tunnels are an obstacle to natural rainfall and artificial irrigation increases soil salinity and, as a consequence, agricultural yields can be significantly reduced.

Global pollinator decline may lead to human malnutrition

The worldwide decline of pollinators could increase cases of vitamin and micronutrient deficiencies in humans, new research suggests. For instance, pollination is needed for the crops that produce half of all plant-derived vitamin A across much of south-east Asia. Furthermore, areas which depend most on pollination for micronutrient supply tend to be poorer and already at higher risk of deficiencies.

Seagrass decline releasing large quantities of carbon

Grasses growing at the bottom of our oceans lock away large quantities of ‘blue carbon’, according to a new study. The results suggest that the soil that seagrass grows on is capable of storing more carbon than soils on land and as a result of the current global decline in seagrass, vast stores of carbon may be being released into the ocean and atmosphere.

New insights into multi-century phytoplankton decline in North Atlantic predict further decline under climate change

Phytoplankton are essential to marine food webs and fisheries. However, a new study indicates that their levels have declined in the North Atlantic since the beginning of the 19th century. This coincides with weakening ocean-circulation patterns, partly caused by melting ice caps. If the melting continues, the study warns of a dramatic fall in North Atlantic plankton levels that could have cascading effects across marine food webs, reducing the ocean’s ability to absorb carbon and threatening the supply of seafood for humans.

Global biodiversity continues to decline

Indications suggest global biodiversity mostly continues to decline, confirming that the goal of halting the rate of loss of biodiversity by 2010 has not been met, according to a recent study. Pressures on biodiversity are increasing despite increasing policy and management responses. However, with greater resources and political will, the researchers argue that the loss of biodiversity could be halted or even reversed.

Biodiversity in decline, but conservation efforts making a difference

One-fifth of the world's mammals, birds, amphibians, reptiles and fish are threatened with extinction, according to a recent report.

Alder tree decline in Europe: how does climate affect the spread of damaging pathogen?

Milder winters under climate change could increase the extent of alder tree (Alnus glutinosa) decline in Europe due to the increased spread of the pathogen Phytophthora alni, a recent study has found. However, this may be offset by hotter summers, which reduce the severity of the disease.

Common European birds have declined more rapidly than rarer species

The number of birds in Europe has fallen by more than 420 million between 1980 and 2009, new research has found. The study, which examined 144 bird species across 25 countries, found that 90% of the lost numbers were accounted for by common species, such as house sparrows (Passer domesticus). The decline was steepest in the first half of the study (1980–1994), followed by a period of greater stability in the second (1995-2009). More needs to be done to conserve common, as well as rare species, the researchers say.

New tool developed to highlight and help prevent declines in freshwater biodiversity

Biodiversity is declining in freshwater ecosystems across the globe, a new study has shown. The researchers created a mathematical model, called GLOBIO- aquatic, which builds a picture of the threats to the biodiversity of rivers, lakes and wetlands that are posed by a variety of human activities. The most crucial of these are land-use changes, nutrient and chemical pollution, and disturbances to the water cycle — which could be from infrastructure such as dams, or from climate change. The authors hope that the model will help policymakers identify regions which are most at risk from these pressures.

Silage harvesting partly responsible for decline in skylarks

Farmland birds like skylarks are attracted to nest in agricultural grassland, but repeated harvesting for silage causes most nests to fail. This study showed that skylark breeding success in silage was too low to sustain local populations. The researchers say that grass silage is a hostile environment for breeding skylarks and conservation efforts should focus on making other parts of the landscape more attractive and productive for nesting birds.

Decline in bees and wasps linked to land-use changes

The declining number of bee and wasp species in England has been linked to historic changes in land-use in a recent study. Researchers say that policies which promote diverse landscapes offer more opportunities for bees and wasps to nest and forage and are best for conserving these insect pollinators.

Speed of life linked to population decline in tuna

The numbers of fish in the world’s oceans are plummeting. Past studies have shown that populations of larger fish tend to decline more steeply. This study assessed the effects of both body size and speed of life (measured by growth rate) on population declines in the tuna family. Analysis of population trends and life history data showed that speed of life better explained population decline than body size.

What do pollinator declines mean for human health?

Human activity is transforming natural systems and endangering the ecosystem services they provide, which has consequences for human health. This study quantified the human health impact of losses to pollination, providing the first global analysis of its kind. The researchers say pollinator declines could increase the global disease burden and recommend increased monitoring of pollinators in at-risk regions, including Eastern and Central Europe.

Warming in the Channel leads to a decline in cold-water fish

Results from a long-term study of fish communities in the Bay of Somme in the English Channel show that numbers of cold-water fish, such as dab and plaice, have been dropping since 1998, as sea temperatures have risen. The researchers say this is evidence of ‘tropicalisation’ in an English-Channel ecosystem. The findings may have implications for conservation policies in the Bay, which is a Marine Protected Area1 designated under the Natura 2000 programme, as well as other marine sites affected by warming.

Flying insects in west German nature reserves suffer decline of more than 76% (1973–2000)

Insect numbers in west German nature reserves have fallen by more than 76% in just 27 years, according to a new study. The fall was even higher in the summer months, with 82% on average fewer insects being recorded. The reasons for this dramatic fall are unclear. The researchers ruled out changes in weather, plant cover and local landscape playing a significant role in the observed decline, but suggest that intensive agriculture and pesticides in fields near to the reserves could be responsible. Whatever the cause, the catastrophic fall in insect numbers will inevitably lead to knock-on effects on ecosystems in the long term, particularly due to their essential role as pollinators and their position in the food web. The researchers say that preserving and protecting insects should now be a priority for conservation policies.

Vertebrate population losses and declines: Earth’s ongoing mass extinction may be more severe than previously estimated

A new study suggests that Earth’s ongoing mass extinction episode is more severe than generally perceived. Rather than focusing on the complete extinction of entire species, researchers analysed the losses and declines of populations in a sample of 27 600 vertebrate species. Population declines and losses are often a prelude to species extinctions. Researchers also conducted a more in-depth analysis of population losses between 1900–2015 in 177 mammal species. The results reveal that rates of population loss and decline in vertebrates are extremely high, even in common “species of low concern”. The data indicates that, in addition to significant species extinction rates, the Earth is experiencing a huge episode of population decline and loss, which will have a significant effect on ecosystem functioning and services. The researchers warn that the window for effective action is closing rapidly and emphasise the need for an urgent response.

Wild pollinators in decline, finds 33-year Great Britain study of bees and hoverflies

To estimate the losses of wild pollinators across Great Britain, a study mapped records of 353 wild bee and hoverfly species, collected across the country from 1980 to 2013. It found that a third of species decreased, while a tenth increased. On average, the geographic range of bee and hoverfly species declined by a quarter, which equates to a net loss of 11 species from each 1km grid square (with uncommon species more harshly affected), highlighting a significant risk to biodiversity, pollinators, and their ecosystems.

Soil quality to decline as climate change hinders litter decomposition by soil fauna

The warmer, drier conditions expected under on-going climate change will reduce the rates at which soil fauna and microbes decompose plant litter, suggests new research from Germany.

New insights into multi-century phytoplankton decline in North Atlantic predict further decline under climate change

Rare earth elements (REE) are used to make many low-carbon technologies, including electric vehicles and wind turbines. Mining and processing of REE, which mostly takes place in China, has a reputation for causing environmental damage. A new study presents a method for evaluating the environmental impacts of REE production based on life-cycle assessment (LCA: a way of determining a product's overall impact during some or all of its journey from extraction to end-of-life). The researchers applied the method to a prospective REE mine in Malawi, south-east Africa, to reveal the most environmentally impactful stages of production, and the greenest source of energy.

Yellow-Cedar Decline In The North Coast Forest District of British Columbia

The distribution of a forest decline of yellow-cedar (Callitropsis nootkatensis (D. Don) Orsted) has been documented in southeast Alaska, but its occurrence in British Columbia was previously unknown. We conducted an aerial survey in the Prince Rupert area in September 2004 to determine if yellow-cedar forests in the North Coast Forest District of British Columbia were experiencing a similar fate as in nearby Alaska. Numerous large areas of concentrated yellow-cedar mortality were found, extending the known distribution of the decline problem 150 km south of the Alaska-British Columbia border. The forests with the most concentrated tree death occurred at 300 to 400 m elevation, frequently on south aspects. The appearance of these forests including proximity to bogs; mixtures of dying, recently killed, and long-dead trees; and crown and bole symptoms of dying trees were all consistent with the phenomenon in southeast Alaska.
