Mountain Goat - Oreamnos americanus

Wildlife populations can too often decline before wildlife managers notice. Although counting animals is one of the most fundamental activities biologists do, it is also the most difficult. Newly published research by the Kitasoo Xai’xais Nation (KXN), the Raincoast Conservation Foundation, and the University of Victoria shows the importance of listening to those that have lived near wildlife for millennia. Their findings, published in the open-access peer-reviewed journal, Conservation Science and Practice, show that mountain goats in KXN territory and beyond in British Columbia are of conservation concern. First to detect the changes, the KXN will be the first to address them with conservation management.

The first signs happened decades ago. KXN community members began to report a decline in sightings of goats once frequently seen from river valleys and the ocean. These patterns were alarming, given the immense cultural value of goats to the Kitasoo Xai’xais people.

“Historically, access to goats influenced the location of village sites and camps. Alarmingly, we don't see goats in these locations anymore, a dramatic decline from several decades ago” Douglas Neasloss, Chief Councillor of the KXN.

Motivated by these early alarm bells from the community, the KXN compiled multiple independent, but complementary, data sources. First, they conducted comprehensive interviews with knowledge holders who collectively had centuries of knowledge and experience in goat country in Kitasoo Xai’xais territory. Participants were asked how frequently they saw mountain goats from 1980 to the present day. The result was a striking decline in the number of goats observed over this time. In 2019, when the interviews were conducted, no one had even seen a goat that year.

Secondly, the KXN led helicopter surveys across more than 500 km2 of KXN territory in the summers of 2019 and 2020 to better understand contemporary mountain goat density. Building upon their own wildlife research program, the KXN collaborated with a team of wildlife scientists, led by Tyler Jessen, PhD student at UVic and scholar with the Raincoast Conservation Foundation, to analyze the data. Results show that KX goats occur in low density, especially when compared to interior populations, such as those that inhabit the Rocky Mountains.

Finally, wanting broader context and yet another independent source of information, the research team also examined hunting records that stretched across BC and back to 1980. They found that the success of BC hunters (unaccompanied by professional guides) has declined over the past four decades. All else being equal, if a hunter has to spend more days looking for a goat to kill than they did in the past, then there may be less goats than there were before. This pattern occurs well beyond KXN territory.

Collectively, these information sources all pointed to the same reality: that mountain goats are of conservation concern in KXN territory; either the abundance or distribution of goats has changed – possibly both. There are either less of these creatures, or they spend more time at high altitudes where they cannot be seen or hunted easily. If they are at higher elevations, this means that something is driving them upwards, such as warming alpine temperatures, which can cause heat stress. Additionally, mountain goat food quality and quality are often reduced at higher elevations. Combined, both of these factors can ultimately lead to population decline.

Either way the Kitasoo Xai’xais, having first detected these patterns, are not going to let these goats slip away. Their thick white coats are adapted to the chilly mountaintops, but as alpine temperatures rise, goats might have less habitat left to escape the heat. Against this climate change background and towards a precautionary approach to reflect the uncertainty around population abundance, the KXN will look to adopting management measures to safeguard these precious and culturally important animals from other harms. Specifically, the KXN are exploring tightening up restrictions within their territory including high-elevation logging, air traffic access, and hunting. Indeed, KXN members voluntarily stopped goat hunting decades ago in response to reduced sightings.

Shedding light on an elusive mountain animal would not have been possible without early insight from KXN. As Jessen explains, “A broader takeaway from this study is that Indigenous peoples commonly detect changes that go undetected by western scientists and managers.”

This study highlights a growing resurgence of Indigenous research and management and shows how pairing Local Ecological Knowledge with scientific information can enhance our collective understanding of ecosystems.

Government guidelines insufficient to protect North American freshwater ecosystem from salt pollution

Current water quality guidelines aren't protecting freshwater ecosystems from increasing salt pollution due to road de-icing salts, agriculture fertilizers, and mining operations, according to an international study that included researchers at Rensselaer Polytechnic Institute. Published today in the Proceedings of the National Academy of Sciences (PNAS), the research shows that freshwater salinization triggers a massive loss of zooplankton and an increase in algae -- even when levels are within the lowest thresholds established in Canada, the U.S., and throughout Europe.

U.S. corn-based ethanol worse for the climate than gasoline, study finds

(Reuters) - Corn-based ethanol, which for years has been mixed in huge quantities into gasoline sold at U.S. pumps, is likely a much bigger contributor to global warming than straight gasoline, according to a study published Monday. Story here.

"AT THE TROUGH." A VIDEO THAT NEEDS TO BE SEEN AGAIN.

Many well-informed, dedicated and concerned individuals produced this video in 2008. Sadly, their warnings about the dirty and dangerous consequences of unregulated factory "farming" in Manitoba have not been heeded. The industry has been given free-rein and continues to expand with few, if any checks and balances. The video is less than an hour long. I implore you to take the time to watch! If you did see it before, perhaps it will remind you again of just how grave these issues really are. If you have not, I know it will concern you, too - perhaps even inspire you to take action of your own. Thank you!

The migratory routes used by the peregrine falcon have been shaped by environmental changes since the last Ice Age, reports a study published in Nature. The paper also presents evidence that the distance travelled during migration is influenced by a genetic factor.

Millions of migratory birds have seasonally favourable breeding grounds in the Arctic, but spend their winters in different locations across Eurasia. However, little is known about the formation, maintenance and future of their migration routes or the genetic determinants of migratory distance.

Xiangjiang Zhan and colleagues combined satellite-tracking data from 56 peregrine falcons from Eurasian Arctic populations with genome data from 35 peregrines to study the migrations of this species. The authors found that five migratory routes were used across Eurasia, which have been shaped by environmental changes since the Last Glacial Maximum (around 20,000–30,000 years ago). Peregrines that migrated longer distances were also found to have a dominant genotype of the gene ADCY8 that — the authors suggest — may be associated with the development of long-term memory.

The authors propose that, in a changing global climate, peregrines in western Eurasia may suffer the highest probability of population declines, move to new wintering areas or perhaps stop migrating altogether. They conclude that using ecological interactions and evolutionary processes to study climate-driven changes in migration could help to facilitate the conservation of migratory birds.

Long-distance movement of microplastics

Microplastics, detected in southern France, could have been transported over 4,500 km from their source, including over continents and oceans, suggests a study published in Nature Communications. The findings suggest that microplastic pollution can spread globally from its sources to remote regions.

Plastic pollution has been documented at high elevations and latitudes, and in regions with little local plastic use. The transportation of microplastics through the atmosphere has been suggested as occurring on regional scales. However, it is unclear how widespread this phenomenon is and, if like mercury and other pollutants, there is free transport of microplastics through the atmosphere that enables trans-continental movement.

Steve Allen and colleagues collected atmospheric microplastics at the high-elevation Pic du Midi Observatory in the French Pyrenees, southern France, and used atmospheric transport modelling to understand the potential sources and paths of these particles. Air masses containing microplastic' particles were found to have moved around 4,550 km on average in the week before arriving at the observatory, and were projected to mainly have arrived from the west and south, over the Atlantic Ocean and Mediterranean Sea. The authors suggest that the potential sources of the microplastics may include North America, western Europe and North Africa, indicating trans-continental and trans-oceanic transport through the free troposphere (the layer of atmosphere above the clouds).

The findings suggest that regions with little local plastic usage could be impacted by microplastic source regions located far away

Record profits for foreign-owned pig conglomerate, recently "gifted" with major grant from Canadian taxpayers to help with its Manitoba operations.

 

Below is a financial statement posted on the company website.

It was recently announced that the governments of Canada and Manitoba were "investing" $2.2 million in three agricultural research projects, to be conducted by the Dutch-based conglomerate, Topigs Norsvin Canada (TN), that will "enhance the competitiveness of Manitoba pork producers."

(And TN, too, no doubt!)

The announcement came despite opposition to a recently approved TN project to build major pig barns near the southern Manitoba community of Plumas. It drew the outrage of many of those residents, along with the citizen group, Hogwatch Manitoba. 

Flooding caused by rapidly expanding hydroelectric dams in the tropics is pushing many jaguars and tigers to the brink of extinction

New research just published, finds hydropower development to satisfy the growing human demand for energy has become one of the major drivers of habitat loss, fragmentation, and degradation everywhere. The dams create massive reservoirs, which drown out the homes of many creatures, including these top predators.

The scientists found no less than 164 dams intruding on more than 25 thousand square kilometres of jaguar range in Latin America. Sadly, plans show that number could well triple into the future.

Four hundred and twenty-one dams we’re found to be ruining or damaging almost 14 thousand square kilometres of tiger habitat in Asia.

While only forty-one dams are planned in the territorial range of tigers, they will still infringe on conservation areas considered important for their conservation.

Researchers conclude that, even though the risks such projects pose to both land habitat and freshwater biodiversity are already known, they’re rarely taken into account.

As a result of their findings, just published in the journal “Communications Biology,” they call for “a more cautious pursuit of hydropower in topographically flat regions, to avoid extensive habitat loss and degradation.”
