The distributed database network provides researchers with millions of specimens' information online.
A more realistic extinction scenario shows that rare and uncommon plant species removal doesn't impact aboveground plant growth, but instead affects remaining rare species. Dominant species impart resistance to ecosystem change even in the face of a 3-fold decline in species.
New research on corals from the Madracis genus reveals significant genetic variation among species, challenging traditional classifications. The study found two distinct species, while four others exhibited considerable overlap in genetic material, making identification difficult.
Study reveals floodplains have significantly higher diversity of native and exotic plants due to flooding, which washes away existing plants and transports seeds. This creates opportunities for invasive species to establish themselves, posing a threat to native plant populations.
A study by Cornell University ecologists found that invasive plants have 77% fewer diseases in their native habitats compared to adopted habitats. The researchers suggest looking for weed-control pathogens both in native and adopted habitats to control invasive plant species.
The introduction of non-native species has accelerated invasions, with many becoming economically beneficial but ecologically destructive. Biocontrol methods are often ineffective and can harm native species.
A comparative study of plants and birds on oceanic islands found that invasive species outnumber native species, causing extinctions but increasing overall diversity. The total number of land bird species has remained relatively unchanged despite the loss of native species.
Scientists are using species profiling to help prevent invasive fish introductions into the Great Lakes and other waterways. A new method has been discovered to detect skin diseases in fish using a fluorescent dye.
A study found that herpes simplex virus-2 (HSV-2) infection may increase the risk of invasive cervical cancer, particularly when combined with human papillomavirus (HPV) infection. The study analyzed data from seven countries and detected HSV-2 antibodies in nearly half of women with cervical cancer, but not in most women without the d...
Researchers used DNA sequences to identify hybridization and introgression in Phlox species, tracing the Eurasian source of invasive Tamarix species. The study found that a novel hybrid plant genotype is contributing to the invasion's spread, affecting biodiversity and hydrology in fragile environments.
Researchers compiled a list of 46 phytoplankton species potentially toxic to humans and marine life, highlighting the need for monitoring programs. The study's findings emphasize the economic cost of harmful algae blooms and their potential impact on global climate modification.
Researchers estimated that New Guinea's plant community is dominated by clusters of closely related plant species, which are fed upon by a greater number of insects. This discovery leads to revised estimates of total world species numbers, with the range being between 4.8 million and 6 million.
Researchers have discovered at least 100 genes that show significant differences in activity between non-invasive ductal carcinoma in situ (DCIS) and invasive breast cancer (IBC). The study's findings suggest that defects in these genes may play a role in the progression from non-invasive to invasive cancer.
