The study recommends protection of the swamp forests adjacent to the southwest border of Lac Télé Community Reserve after recent surveys confirmed that high densities of the great apes still exist in the remote location.
The findings and recommendations appear in the November issue of the journal Oryx. The study’s authors include: Hugo Rainey, Emma Stokes, Fiona Maisels, Samantha Strindberg, Fortuné Iyenguet, Guy-Aimé Malanda, and Bola Madzoké from the Wildlife Conservation Society: and Domingos Dos Santos from the Republic of Congo Minstère de l’Economie Forestière.
The swamp also supports large numbers of chimpanzees, red colobus monkeys, elephants, and other rain forest species. According to the study, imminent threats to the swamp include new logging operations, oil exploration, an influx of refugees from neighboring Democratic Republic of Congo, and, resulting from these developments, an increase in the human population, construction of roads and other infrastructure, and the escalation of the illegal bushmeat trade.
“We implore both the Government of the Republic of Congo and the international community to begin the groundwork for the creation of a new protected area to safeguard these gorillas and their unique environment for the benefit of future generations,” said Dr. James Deutsch, WCS Director for Africa Programs. “Losing gorillas in this region after all the attention from their discovery would be a sad coda on an otherwise great story.”
“The world was electrified at the discovery of more than 125,000 western lowland gorillas still in existence in the heart of Africa’s rain forests, which include the recently surveyed gorillas just outside of Lac Télé,” said WCS researcher Dr. Hugo Rainey, the paper’s lead author. “Now that the thrill is gone, we can’t forget about the most important part of wildlife surveys: protecting what we find.”
Using methodologies based on counting the nests constructed by gorillas and the decay rates of these temporary structures, the researchers calculated that the study area (measuring 1,029 square kilometers, or 379 square miles, in size) contained an estimated population of 5,042 gorillas, more in fact than previous estimates for the site. The result is one of the highest density estimates ever calculated for gorillas—more than five gorillas per square kilometer (more than 13 gorillas per square mile).
The study site was the easternmost part of the gorilla census announced last year that produced a jaw-dropping estimate of more than 125,000 western lowland gorillas for the region.
Funders for the surveys and project include the U.S. Fish & Wildlife Service and the USAID-Central Africa Regional Program for the Environment (CARPE).

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
