Wild megalopolis: Study shows unexpected pockets of biodiversity pepper Los Angeles      (via sciencedaily.com)     Original source 

Researchers, in partnership with the city of Los Angeles, have developed the urban association index to help identify how well or poorly individual wildlife species are doing in the city. The researchers found unexpected pockets of biodiversity deep in the city, but they say it will still be a challenge to elevate Los Angeles' overall level of biodiversity.

Tiger beetles fight off bat attacks with ultrasonic mimicry      (via sciencedaily.com)     Original source 

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths.

Saturated soils could impact survival of young trees planted to address climate change      (via sciencedaily.com)     Original source 

New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.

Protecting endangered monkeys from poachers, habitat loss      (via sciencedaily.com)     Original source 

The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.

Hornets found to be primary pollinators of two Angelica species      (via sciencedaily.com)     Original source 

Researcher discovered that two species in the genus Angelica are pollinated primarily by hornets. This overturns the conventional belief that Angelica species are 'generalists,' meaning that there is not one primary pollinator but a variety of species. As hornets are rarely primary pollinators, the discovery also impacts future ecological research and conservation efforts.

Unveiling the lionfish invasion in the Mediterranean Sea      (via sciencedaily.com)     Original source 

Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
