A new species of tiny creature has been discovered living on the floor of the Amazon rainforest. The creature, which has been named Dendroctonus micans, is only a few millimetres long and is covered in a fine fuzz of hair. It is thought to be a relative of the more familiar dust mite, and is the first member of its family to be found in the Amazon.

The creature was discovered by a team of Brazilian and American scientists, who were studying the rainforest floor for new species of life. The team's leader, Dr Paulo de Souza, said that the creature was "very unusual" and "quite different" from any other known mite.

The creature is so small that it can only be seen clearly through a microscope. It is not yet known what it eats, but it is thought to feed on the same kind of fungus that dust mites do.

The discovery of the Dendroctonus micans is important because it shows that the Amazon rainforest is home to a huge variety of life, even in the most unexpected places. The rainforest is under threat from deforestation and other human activities, and so it is vital that we conserve it.

Tiny pests eating New Jersey's pines march north as climate changes, report says

Love the warmer winters we’ve been enjoying? So does the southern pine beetle, a rice-grain-sized pest that has munched through New Jersey’s pine forests and could be a harbinger of climate change, according to a new study.

Using the Garden State as a barometer, researchers from Columbia University, the University of Vermont and the U.S. Forestry Service measured temperatures and their relationship to where the beetles were spreading.

They found that the temperature of tree bark on the coldest night of the year is critical. The destructive pests feed on the living tissue under the bark, introducing blue stain fungi. If the bark remains cold enough, the pests can’t do their damage.

But the temperature on the coldest night of the year in New Jersey has been rising due to climate change, the researchers say, creating a path for the insect to start an invasion that eventually will spread into into the northern United States and southern Canada. The lows are rising much faster than average temperatures, they said.

Southern New Jersey is critical because of its 440,000 acres of pine forests. The researchers picked the southern pine beetle as a climate change focus because it seems so sensitive to temperature. And, it is responsible for destroying $1.7 billion worth of timber between 1990 and 2014 in southeastern states.

“I think the presence and destructiveness of the southern pine beetle in New Jersey is well established. It’s been a problem for 15 years,” said co-author Corey Lesk, a PhD candidate at Columbia University’s Center for Climate Systems Research. The study was published Monday in the research journal Nature Climate Change.

“But it’s spreading north rather quickly,” Lesk said. “Our study uses the data from southern New Jersey in relation to how it’s moving north. The coldest night of the winter seems to dictate whether the southern pine beetle can live.”

The group established that bark temperature of about -10 Celsius, or about 14 degrees Fahrenheit, is the limit at which the beetle can survive. Since 1980, they found, the coldest night of the year above 14-degrees has migrated north in New Jersey by about 40 miles per decade. And the beetles have been moving north too, by about 53 miles per decade since 2002. The cold weather connection has long been known. But the new study predicts how far and fast the beetles will spread, given warming temperatures. Using historic climate data, the team projects that the annual minimum air temperature will continue to rise a few degrees per year in the northeast.

“Given this warming trend and our criteria for southern pine beetle-suitable climates, vast areas across the northeastern United States and southern Ontario and Quebec are projected to become climatically hospitable” to the beetle before 2080, the researchers wrote. However, the study notes that the beetle will become established along the Atlantic coastline into Maine by 2020 because of the more moderate temperatures there. It will take more time to roam further inland.

But the shortfall in supply is also part of an older saga, involving Dendroctonus ponderosae: the mountain pine beetle, a quarter-inch insect with a shiny black exoskeleton. The beetle has been in Canadian forests for decades, but they’re usually kept in check by cold winters, said Kevin Mason, managing director of ERA Forest Products Research, a Montreal-based research company.

But in the late 1990s, the beetles started to live longer and reproduce quicker—an outcome, scientists believe, of a warming climate. They swarmed through the pines of British Columbia, attacking more than 44 million acres of forest, an area four times the size of Switzerland. “You could go up in an airplane above British Columbia and see the damage,” Mason said. “I’m a little color-blind, but others could see it better than me. The dead pines had a red tinge to them, so you could fly an hour and just see this red kill.”

Before the infestation, British Columbia used to provide 15-17% of the lumber going into US markets, making up half of Canada’s lumber exports across the border. After the infestation, those numbers dropped, Mason said: “There were points where, for British Columbia, the figure was below 10%, and Canada now is at around 25%.“

Many pines killed by the beetle could still be harvested for a period of 5-10 years, and the government of British Columbia offered incentives to the industry to process these dead trees. Mason thinks roughly 800 million cubic meters of dead pine was harvested over a period of 15-odd years, until 2015 or thereabouts. But once that was done, forests had to regrow.”We’re talking about a diminished harvest in British Columbia for decades,” Mason says.

range shift of phytophagous insects

The current distribution pattern in most insect species is effect of climate. The phenomenon can be observed particularly on range borders where temperature is a main limiting factor. For instance, –16°C is the critical value for North American species of bark beetle Dendroctonus frontalisZimm., which is one of the most dangerous pests for coniferous trees in the region. Nearly absolute mortality of the population occurs below this value. Such temperature is observed on the northern range border of the aforementioned species (Ayres, Lombardero, 2000). It implies that average temperature increase can enable more termophilous species to expand in the northern direction and on higher altitudes.

Simultaneously, southern and lower range borders can be shifted (Parmesan 1996; Walther et al., 2002; Parmesan, Yohe 2003; Menéndez 2007; Battisti 2008). With regard to many phytophagous insects, a range increase is probable also because species’ ranges are smaller than areas where their host plants grow. Many examples of insects’ range shift were observed in recent years. In the 1990s, few leaf mining moths of the family Gracillariidae have occurred in the Central Europe, including Poland (Šefrová 2003). The horse-chestnut leaf miner Cameraria ohridella Deschka & Dimić that attacks horse chestnuts Aesculus hippocastanum was the most spectacular example among them. Apart from this accidental introduction of the pest, shifting of the northern and eastern range borders, as a result of temperature increase, was the most probable cause of the species expansion to new areas. Range shift of forest folivores in Europe has been well researched for two species of geometrid moths, Winter moth, O. brumata, and Autumnal moth, Epirrita autumnata (Borkh.), in forest stands of northern Scandinavia (Jepsen et al., 2008). Cyclic outbreaks have been observed for both species in the aforementioned area, sometimes leading to substantial loss of foliage. For the last 15–20 years, areas of both defoliators’ mass outbreaks have been increased significantly. Operophtera brumata, a species less resistant to low temperature, has expanded to the north-east to areas where E. autumnata was the dominant species so far. The latter has increased range to areas located inland and characterised by cooler climate. The Pine processionary moth Thaumetopoea pityocampa Den. & Schiff are another well-documented examples of the species range shift with regard to the influence on forest management. The species is recognised to be one of the main foliophagous pests in the Mediterranean region. Temperature in winter, when caterpillars feed on needles of various pine species (rarely on other coniferous species), is the main factor that influences range limits of T. pityocampa. From the mid-1970s to 2004, the species enlarged its range in France to the north direction by almost 90 km. In the same period, its upper range border in Italian Alps moved up by over 200 m in some regions (Battisti 2008; Battisti et al., 2005). Same observations have been made for changes in an upper range border of the species in Spanish Sierra Nevada (Hódar, Zamora 2004). Average temperature increase enabled expansions to areas that have not been colonised before. Higher survivability of caterpillars in winter, during feeding time, was observed (Battisti et al., 2005, Buffo et al., 2007), whereas warmer nights in summer (with temperature over 14°C) influenced distance and altitude increase of female expansion (Battisti et al., 2006). It has been often pointed out at the necessity of constant monitoring of insects range shifts and of selecting either species or groups of insect species that would indicate changes in forest environment (for instance, Ayres, Lombardero 2000; Bale et al., 2002; Logan et al. 2003; Menéndez et al., 2007). Attempts at predicting species range shift have also been made (for instance, Williams, Liebhold 1995 a,b; Jönsson et al. 2007; Régnière 2009). Apart from these ecological requirements of indicator organisms, varied factors are included in the aforementioned research, such as typology (for instance, the type of habitats and plant formations) and climate parameters (average, minimum and maximum temperature/precipitation per month). The variability of the latter implies noticeable bias in any attempts to predict changes in insects range. Hence, such predictions can only be seen as possible scenarios. Results can be influenced by relatively small changes in parameters that with regard to climate unpredictability (even in few-year scale) can hinder from making any exact prognosis. Williams and Liebhold (1995a, b) have conducted prognostic research on insect range shift. They have used data on defoliated forest stands in the states of Oregon and Pennsylvania that

were previously exposed to attacks of tortricid moth Choristoneura occidentalis Free and of L. dispar. Alternative scenarios have been discussed include: (a) average temperature increase by 2°C and unchanged precipitation level, (b) average temperature increase by 2°C and precipitation level decrease by 0.5 mm/day and (c) average increase in values of both parameters. Average temperature increase and unchanged precipitation level have been factors that caused L. dispar expansion increases, while predicted range of Ch. occidentalis has decreased. The increasing assumed temperature and decreasing precipitation level have caused range decrease of both defoliators, whereas increase of both parameters was positively correlated with the growth of the outbreaks areas.

Dendroctonus valens added to the EPPO Alert List

The red turpentine beetle, Dendroctonus valens (Coleoptera: Scolytidae), originating from North America was introduced into China (counties of Yangcheng and Xinshui - Shanxi province) in the early 1980s. In 1999, it was found in Hebei province and by 2003 this bark beetle had spread to 85 counties in 3 provinces of Northern China covering an area of more than 700 000 ha causing damage to pine trees. In China, it is estimated that D. valens has killed more than 10 million pine trees since its introduction, mainly Pinus tabulaeformis (Chinese red pine), a species which has been widely planted in monoculture during reforestation programmes. Genetic studies conducted in China in 2005 indicated that D. valens was introduced from the Pacific Northwest of the USA, probably via multiple introductions. However, other studies comparing the symbiont fungi associated with D. valens in North America and China, suggest an introduction from Eastern North America. It is suspected that the introduction of D. valens into China has been associated with imports of unprocessed logs of Pinus ponderosa for use in mine construction. Considering this ‘continental jump’ and the severity of damage reported from China, the EPPO Panel on Quarantine Pests for Forestry recommended that D. valens should be added to the EPPO Alert List
