Ant Diversity of the Xisha Islands: Community Structure, Exotic Species Colonization, and Ecological Functions in a Tropical Coral Archipelago

open access: yesBiological Diversity, EarlyView.
The first inventory of ants from the Xisha Islands of the South China Sea was compiled, revealing 21 species: 70% native and 30% exotic. Anthropogenic disturbance primarily drove exotic colonization, whereas island area showed weak positive effects on species richness. Most ants were omnivorous, with key mutualistic and seed‐dispersal roles.

Photosystem II efficiency in response to diurnal and seasonal variations in photon flux density and air temperature for green, yellow-green, and purple-leaved cultivars of sweet potato [Ipomoea batatas (L.) Lam]

open access: yesPhotosynthetica
This study aimed to investigate the impact of diurnal and seasonal variations in photon flux density (PPFD) and air temperature on PSII efficiency in three sweet potato leaf-color cultivars: green (G), yellow-green (Y), and purple (P). The cultivars were

Endemic Species Of Flora Kuhitang Ridge

open access: yesThe American Journal of Agriculture and Biomedical Engineering, 2020
The article says that of the 25 endemic species of the Kugitang flora, 18 species are found in the eastern part of the ridge, i.e. within Uzbekistan. All endemic to the Uzbek part are protected by the Surkhan reserve. This indicator indicates the great importance of the Surkhan reserve in the gene pool of the Kugitang plant diversity.

Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Antimicrobial Activity of Three Endemic Verbascum Species

open access: yesPharmaceutical Biology, 2002
The extracts obtained from three Verbascum L. species (Verbascum olympicum Boiss., Verbascum prusianum Boiss., and Verbascum bombyciferum Boiss.) have been investigated for their antimicrobial activity. Growth inhibition, using the agar disc diffusion assay, was determined against Escherichia coli ATCC 11230, Micrococcus luteus La 2971, Staphylococcus ...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Convergent evolution of kidney sizes and supraorbital salt glands for birds living in saline habitats

open access: yesiScience
Summary: Only a small number of avian species inhabit salty environments. To understand how they adapted, we examined the evolution of kidney sizes, supraorbital salt glands (SSGs), and the utilization of salty habitats across 230 species spanning 25 ...

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

Species richness and endemism in the native flora of California

open access: yesAmerican Journal of Botany, 2017
PREMISE OF THE STUDY:California's vascular flora is the most diverse and threatened in temperate North America. Previous studies of spatial patterns of Californian plant diversity have been limited by traditional metrics, non‐uniform geographic units, and distributional data derived from floristic descriptions for only a subset of species.METHODS:We ...
