#IllegalKilling was the main cause of #mortality (33.8%), and mortality rates were similar in protected and hunted populations (8.6% and 7.0% per year, respectively). Due to the low natural mortality rates in protected and hunted populations, #anthropogenic causes of mortality are likely close to additive, such that maintaining or increasing refuge #habitat with little human #disturbance is critical to lynx #conservation.

Inverted resistivity model from AMT data showing the subsurface rock resistivity structure in South Mount Meager (figure modified from Hormozzade Ghalati et al., 2022). a) resistivity slice at 500 m elevation (asl) showing two distinct high conductive anomalies and locations of the cross sections. Cross sections b) and c) in W-E direction, and d) and e) in N-S direction. Anomaly C1 is spatially in accordance with the occurrence of hot-warm spring swarms along the margin of the volcanic complex. Anomaly C2 appears in a circular shape, coincident spatially with the core area of the known deep geothermal prospect.

Extinction in tropical forests. This study uses a standardized pan-tropical dataset of 239 mammal species from 37 forests in 3 continents to reveal selective #extinction occurring within #TropicalForests triggered by #anthropogenic pressure in the broader landscape #plosbiology https://plos.io/4jVaeyZ

Map of the 37 tropical forest areas considered in the study. Top: Map of the forest areas; inset maps represent 2 protected areas embedded in contrasting landscapes: landscapes with low human density (left) and landscapes with high human density (right). Green areas in the inset maps represent PA boundaries. Bottom: chart shows estimated species richness (black dots) and the observed number of detected species with camera-traps (blue triangles) in each forest, which are ordered by increasing human density.

Levels of microplastics in human brains may be rapidly rising, study suggests

"The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study."

"The human body is widely contaminated by microplastics. They have also been found in blood, semen, breast milk, placentas and bone marrow. The impact on human health is largely unknown, but they have been linked to strokes and heart attacks".

“We found that the smaller organisms that we sampled seem to be ingesting more #anthropogenic, non-nutritious particles,” Granek said. “Shrimp and small fish, like herring, are eating smaller food items like #zooplankton…and these anthropogenic particles may resemble zooplankton and thus be taken up for animals that feed on zooplankton.”

#microplastics

The team quantified anthropogenic particles that they found in the edible tissue of six species that are economically or culturally important in Oregon (clockwise from top left): Chinook salmon, lingcod, black rockfish, pink shrimp, Pacific herring, and Pacific lamprey (NOAA Fisheries, Oregon Department of Fish & Wildlife, North Carolina Wildlife Resource Commission).

But over the past decade, researchers have ventured into this environment and have come up with surprising findings.

Human use of fire has produced an era of uncontrolled burning: Welcome to the #Pyrocene

by Stephen Pyne, The Conversation, January 22, 2025

"#LosAngeles is burning, but it isn't alone. In recent years, fires have blasted through cities in #Colorado, the southern #Appalachians and the island of #Maui, along with #Canada, #Australia, #Portugal and #Greece. What wasn't burned was smoked in.

"Is this another case of a future not only dire but strange, without a narrative to join past to present or an analog for what is to come?

"I'm a historian of fire, and my reply is that we have both a narrative and an analog. The narrative is the unbroken saga of humanity and fire, a companionship that extends through all our existence as a species. The analog is that humanity's fire practices have become so vast, especially in recent centuries, that we are creating the fire equivalent of an ice age."

[...]

Welcome to the Pyrocene

"Widen the aperture a bit, and we can envision Earth entering a fire age comparable to the ice ages of the Pleistocene, complete with the pyric equivalent of ice sheets, pluvial lakes, periglacial outwash plains, mass extinctions and sea-level changes. It's an epoch in which fire is both prime mover and principal expression.

"Humanity's firepower underpins the #Anthropocene, which is the outcome not just of #anthropogenic meddling but of a particular kind of meddling, made possible by humans' species monopoly over fire. Even climate history has become a subset of fire history.

"Fires in living landscapes, fires burning lithic landscapes—the interaction of these two realms of fire has not been much studied. It's been enough of a stretch to fully include human fire practices within traditional ecology. Yet humans—the keystone species for fire on Earth—are merging the two arenas of earthly burning with a give and take that is reshaping the planet in what resembles a slow-motion #Ragnarok.

"Add up all the effects, direct and indirect: the ice driven off by fire, the areas burning, the biogeographical #migrations as biotas move to accommodate changed conditions, the collateral impacts with damaged #watersheds and #airsheds, the unraveling of #ecosystems, the pervasive power of #ClimateChange, #RisingSeaLevels, a #MassExtinction, the disruption of human life and habitats. The result is a #pyrogeography that looks eerily like an ice age for fire. You have a maturing Pyrocene.
