From pets to pests: How domestic rabbits survive the wilderness      (via sciencedaily.com)     Original source 

How do rabbits go from fluffy pets to marauding invaders? Rabbits have colonized countries worldwide, often with dire economic and ecological consequences, but their secret has until now been a mystery. Biologists sequenced the genomes of nearly 300 rabbits from across three continents to unveil the key genetic changes that make these animals master colonizers.

To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say      (via sciencedaily.com)     Original source 

Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.

'Masters of shape-shifting': How darkling beetles conquered the world      (via sciencedaily.com)     Original source 

Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.

Will climate change lead to the extinction of a newly discovered tarantula species?      (via sciencedaily.com)     Original source 

Biologists have discovered a new species of tarantula from the Madrean Sky Island biodiversity hotspot in southeastern Arizona. This remarkable new species is endemic to the Chiricahua Mountains and is predominately distributed in mid- to high-elevation forests, which are increasingly threatened due to climate change.

Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia      (via sciencedaily.com)     Original source 

Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.

Historic map reveals how mussel farm is bringing shellfish reefs back to the seabed      (via sciencedaily.com)     Original source 

New analysis has shown that the UK's first large scale offshore mussel farm might in fact serve as a form of restoration rather than creating habitats never seen in the area before. A map dating from 1871 shows a large area of the seabed -- stretching from Torquay in the west and beyond Lyme Regis to the east -- as being home to 'rich shell beds'. The region has now been transformed from muddy sediment with limited biodiversity into reefs, which research has shown have the potential to benefit a number of commercial fish and crustacean species and the ecosystem more generally.

Study reveals urban trees suffer more from heat waves and drought than their rural counterparts      (via sciencedaily.com)     Original source 

A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.

House call: A new study rethinks early Christian landmark      (via sciencedaily.com)     Original source 

Since its discovery by modern researchers a century ago, an ancient structure known as the 'Christian building' has become widely considered the cornerstone of early Christian architecture. Constructed around 232 C.E. in the ancient city of Dura-Europos, a Roman garrison town in what is now eastern Syria, the building is the only example of a 'house church,' or domus ecclesiae, a domestic space that was renovated for worship by Christians at a time when the open practice of their faith is thought to have made them subject to persecution.
