4Biology is a focused search engine built for biology students, researchers, educators, and lab managers. We combine multiple indexes, curated sources, and AI tools to surface publications, protocols, datasets, suppliers, and learning resources that matter to life scientists. Use the site to save time, find specialized resources, and get context-specific search results not optimized for general web traffic. Part of the 4SEARCH network of topic specific search engines.
A chromosome-by-chromosome survey of seven wild daffodil taxa across northern Algeria has settled long-running disputes over species boundaries, ploidy levels and hybrid identity in the genus Narcissus.
A four-year study of European green lizards in a Czech river valley reveals that scree, rocks, shrubs and nearby shelters are the key microhabitat features sustaining isolated populations at the northern edge of the species' range.
Three plants with very different lives — a wild rice hiding in Sri Lankan swamps, a saxifrage clinging to the highest Dolomite peaks, and a rock rose on Sardinian sea cliffs — have just received formal conservation assessments under the Subject of…
A synthesis of oxygen consumption data from 37 groundwater species reveals universal metabolic scaling with body mass but a thermal break above 18 degrees Celsius that leaves stygobitic fauna metabolically vulnerable to climate warming. Subject of Research: groundwater ecology Article Title: Metabolic…
A new kinetic theory shows that protein denaturation, not lipid membrane breakdown, drives photosynthetic heat failure and caps plant heat tolerance near 60 degrees Celsius. Yet for more than a century, ecologists and plant physiologists have argued about what actually causes…
Whole-genome resequencing of 197 gardenia accessions from nine Chinese populations reveals millions of genomic variants, clear geographic structure, and selection signals in pathways tied to the plant's medicinal and ornamental value.
A new ensemble species distribution model using 121 verified records reveals that the Brazilian free-tailed bat's South American subspecies avoids the Amazon, favors human settlements, and is fragmented by Andean barriers.
Genetic and morphological analyses of freshwater snails from Lake Biwa have led to the redescription of Semisulcospira reticulata and the description of a new species, Semisulcospira nishimurai, from sandy mud habitats.
Molecular and morphological evidence reveals two new flightless lace bug species from Hachijo Island and the Kerama Group, bringing Japan's Agramma fauna to four species.
A newly described coprophilous fungus from Kenyan cow dung, Schizothecium keniense, produces the novel alkaloid pyrrospirone Z and other decahydrofluorene metabolites with notable antibacterial and cytotoxic activity.
