Prairie strips have been shown to significantly reduce soil erosion, improve water quality, and increase beneficial insect populations. By converting a small portion of a crop field to prairie, farmers can lower their financial costs while creating numerous ecological benefits.
A new study found that ancient animal herders in Africa added to the ecological richness and diversity of the savanna thousands of years ago. Their practice of penning cattle, goats, and sheep at night created nutrient-rich grassy glades, or hotspots, that still attract wildlife and have increased habitat diversity in the region.
Researchers analyzed ecological features and DNA sequencing data to reconstruct the tree of life of aquatic macroinvertebrates in Europe. They found that oldest lineages have higher functional diversity than younger ones, which is influenced by their ability to colonize new habitats.
Human habitat alteration leads to global phylogenetic homogenization, replacing diverse species with similar clades. Average loss of 13.5% in phylogenetic diversity reported across five continents.
A Rutgers University-Camden study found that urban insects are more resilient in extreme weather due to adaptations to high-stress urban environments. Arthropod diversity declined after Hurricane Sandy in New York City parks, becoming indistinguishable from street medians.
Researchers investigated habitat diversity's impact on coastal sediment ecosystems and found that more habitats scored better in functionality than single-habitat ecosystems. Human activities like habitat homogenization threaten both species and habitat diversity.
Researchers at Oregon State University found that northern sockeye salmon can thermostate to find water temperatures that meet their physiological needs, reducing energy expenditure during heat waves. By moving to tributary plumes or deeper water, the fish conserve energy and avoid extreme temperatures.
A study reveals Ottawa as a biodiversity hotspot for Microgastrinae wasps, with 158 species recorded. This surpasses the total number of species found in Canada and Ontario, showcasing the region's unique habitats and diversity.
A new species of fungus-parasitizing orchid, Lecanorchis tabugawaensis, has been discovered in Japan. The orchid obtains its nutrients through a special symbiotic relationship with fungi, a phenomenon known as mycoheterotrophy.
A recent study estimated lake-wide fungal diversity for the first time and found that each habitat type has a distinct community, with biofilms being hotspots for aquatic fungi. The research highlights the importance of considering habitat heterogeneity when assessing fungal diversity in water bodies.
Researchers found that habitat warming decreases Anomura species diversity in marine environments, while increasing it in freshwater habitats. This suggests a habitat-dependent response to climate change, challenging the universal trend of increased diversity with warming temperatures.
A new species of nocturnal gecko, Paroedura hordiesi, has been discovered in northern Madagascar with a unique camouflage pattern to blend into its environment. The species is classified as Critically Endangered due to habitat loss and degradation.
A new study finds that diversified farming systems retain more evolutionary history than intensive agriculture, suggesting a strategy for conserving biodiversity. This is encouraging news as human activities drive half of known life to extinction.
A recent study published in Urban Ecosystems found that a lack of plant diversity is a significant contributor to the widespread defoliation caused by cankerworms in cities. Increasing plant diversity can help limit future damage. Native plants were particularly hard hit, while nonnative species were largely ignored.
A new orchid species, Lophiaris silverarum, has been named after UC Riverside researcher Katia Silvera. The species was discovered in central Panama and is currently growing only in that region. Its slow growth rate makes it rare and difficult to cultivate.
Researchers found that suitable habitats were settled first by early migrants, leading to a diverse patchwork of language groups. This process may account for global ethnolinguistic patterns.
A diverse landscape of patches, including meadows, young and old forests, and shrub lands, can provide more benefits than a single high-biodiversity patch
The study reveals a spectacular degree of evolutionary divergence in the satyrine butterfly genus Calisto, with 34 species and 17 subspecies identified. This radiation is believed to have occurred over a period of 4-8 million years, driven by ancient dispersal events rather than plate tectonics.
A team of scientists mapped global diversity patterns for over 11,000 marine species, finding temperature strongly linked to biodiversity and high overlap between areas of human impact and diversity hotspots. The study suggests ocean warming may greatly affect the distribution of life in the sea.
A new study by UK Centre for Ecology & Hydrology and colleagues found that diverse landscapes with varying habitats help maintain stable butterfly populations. This can aid conservation efforts, as stable populations are better equipped to withstand extreme weather conditions.
Researchers successfully built a scale model of a living meandering river, demonstrating the critical role of vegetation in slowing erosion and reinforcing banks. Sand, typically avoided in stream restoration, was found to be essential for building point bars and blocking cut-off channels, leading to a more balanced ecosystem.
Scientists assess native plant diversity to evaluate invasion vulnerability and protect native plants, innovative field methods presented in a new book by USGS ecologist Tom Stohlgren. The book provides revised sampling approaches for measuring plant diversity at multiple scales, helping natural resource managers make informed decisions
Researchers found that an ancient marine invasion led to a significant increase in regional diversity, with gamma diversity rising by 26% due to changes in beta diversity. The study suggests that habitat distribution or increased habitat diversity may have contributed to this increase.
A team of scientists used artificial life to study evolution and diversity in nature, finding that there are limiting effects of productivity in finite environments. This research provides insights into the ecological relationship between environmental productivity and species diversity.
This study demonstrates that Symphonia globulifera, a widespread tropical rainforest tree, has a complex evolutionary history shaped by oceanic currents and land bridges. The research revealed distinct phylogeographic structure in Panama's Isthmus, linked to its historical connection with Central America and South America.
Caterpillars' shelter-building habits impact insect communities by reducing diversity, whereas artificial habitats have similar effects as natural ones. The study suggests regional patterns of insect herbivore diversity may be influenced by these ecosystem engineers.
