Elephants Adapt to Poaching

Elephants in eastern Africa have learned to travel at night and hide during the day to avoid poachers who are hunting tuskers into extinction, researchers reported Wednesday.

Normally elephants forage for food and migrate in daylight, resting under cover of darkness. But a sharp increase in illegal hunting driven by the global trade in ivory has forced the massive mammals to upend their usual habits.

In an upcoming study, Ihwagi details his findings, based on data gathered from 60 elephants in northern Kenya tracked with GPS devices for up to three years during the period 2002 to 2012.

The nighttime movements of the elephants increased significantly in sync with poaching levels, especially for females. In high-danger zones, females reduced daytime activity by about 50 percent on average compared to low-danger zones.

According to the International Union for Conservation of Nature (IUCN), the number of African elephants has fallen by around 111,000 to 415,000 over the past decade.

The killing shows no sign of abating, with around 30,000 elephants slaughtered for their ivory every year, mainly to satisfy demand in Asia for products coveted as a traditional medicine or as status symbols.


Human infection with avian influenza A(H7N9) virus – China

On 18, 25 August and 4 September 2017, the National Health and Family Planning Commission of China (NHFPC) notified WHO of four additional laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus in China.


Roundup of Global Volcanic Activity – New Activity for the week of 6 September-12 September 2017

Aoba | Vanuatu : On 30 August the Vanuatu Geohazards Observatory (VGO) stated that conditions at Aoba had been changing, increasing the potential for eruptive activity. On 6 September a VGO report noted that activity continued to increase; the Alert Level was raised to 3 (on a scale of 0-4) signifying that the volcano is in a minor eruption phase. VGO reminded residents and tourists not to approach the volcano within a 3-km radius, and to stay out of areas subject to trade-wind exposure.

Fernandina | Ecuador : IG reported that activity at Fernandina began on 4 September with the detection of hybrid earthquakes followed by long-period events, and finally the onset of tremor at 1225 which heralded the beginning of the eruption. Lava emerged from a circumferential fissure near the SSW rim of the caldera and flowed down the S and SW flanks (with no evidence of the flows reaching the sea). A gas plume with low ash content rose 4 km above the crater rim and drifted W. Flows continued to be active on 5 September but by the evening the intensity had weakened. An eruptive plume rose about 2.5 km. Activity decreased significantly by 6 September.

Nevados de Chillan | Chile : According to Oficina Nacional de Emergencia-Ministerio del Interior (ONEMI), Servicio Nacional de Geología and Minería (SERNAGEOMIN) Observatorio Volcanológico de Los Andes del Sur (OVDAS) reported that during 16-31 August phreato-magmatic explosions at Nevados de Chillán’s Volcán Arrau dome complex had decreased. The Alert Level remained at Yellow, the middle level on a three-colour scale, and the public was reminded not to approach the craters within a 3-km radius.

Villarrica | Chile : In a summary of August activity at Villarrica, Proyecto Observación Villarrica Internet (POVI) reported that the crater was only partially visible on nine days. On 2 September a small incandescent vent at the bottom of the crater was visible. An explosion at 0924 on 30 August ejected gas and ash that drifted E due to strong winds; observers noted ash and lapilli deposits on the snow during a field visit later that day.
