Researchers argue that the rapid growth in urban honeybee-keeping over the past decade may be negatively impacting nearby wild bee populations. Small bees with limited foraging ranges may be especially at risk, they write.

What's good for the Black-backed Woodpecker is good for restoration of burned California forests. The birds' unique relationship with fire underpins the latest research into improved post-fire management. A study describes a new tool that factors in how fires burn into forest management decisions and turns science into action for wildlife conservation.

Anthropogenic climate change has, together with the intensive use and destruction of natural ecosystems through agriculture, fishing and industry, sparked an unprecedented loss of biodiversity that continues to worsen. In this regard, the climate crisis and biodiversity crisis are often viewed as two separate catastrophes. An international team of researchers calls for adopting a new perspective.

A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.

Researchers have discovered how long ago the Australian Nullarbor plain dried out, with a new approach shedding light on how ancient climate change altered some of the driest regions of our planet.

Over the past 40 years, the financial losses caused by biological invasions have been equivalent to those caused by various types of natural disasters, such as earthquakes, floods or storms; however, according to scientists, they are now increasing at a faster pace.

Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.

The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.

Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.

New research led by a paleobotanist provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer than it is today.

A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces.  When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.

The island of Dominica took a direct hit from Category 5 Hurricane Maria. Nine months afterward, researchers found that while 89% percent of trees located in nine previously documented forest stands were damaged, but only 10 percent had immediately died. The most common damage was stem snapping and major branch damage. The damage with the highest rates of mortality were uprooting and being crushed by a neighboring tree. Large individual trees and species with lower wood density were susceptible to snapping, uprooting and mortality. Those on steeper slopes were more prone to being crushed by neighboring trees.

Important species often get overlooked if they lack flashy colors or charismatic behavior. This is true of euptychiine butterflies, one of the most common insects in the Amazon Rainforest that have been largely ignored by scientists and naturalists throughout the 20th century. A new study pieces together the natural history of the group, in which males can look so unlike females, they've been repeatedly mistaken for separate species, diversity has been drastically underestimated, and more than 100 unnamed species are waiting on scientific description.

An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.

Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.

A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
