Archaeobotanical implications of phytolith assemblages from cultivated rice systems, wild rice stands and macro-regional patterns [PDF]

open access: yes, 2013
Rice can be cultivated in a range of arable systems, including upland rainfed, lowland rainfed or irrigated, flooded or décrue, and deep water cultivation.

Traits, habitats, and clades: Identifying traits of potential importance to environmental filtering [PDF]

open access: yes, 2009
Environmental filtering is a fundamental process in the ecological assembly of communities. Recently developed phylogenetic tools identify patterns associated with environmental filtering across whole communities.

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

A survey of selected coastal vegetation communities of Florida [PDF]

open access: yes, 1977
A survey of coastal vegetation around Florida was conducted during 1973 and 1974. Seventeen sites were selected and sampled using the transect method to determine species occurrence, relative densities, and habitat development and structure.

Niche-breadth of freshwater macrophytes occurring in tropical southern African rivers predicts species global latitudinal range [PDF]

open access: yes, 2016
The study tested the hypothesis that measurement, using multivariate Principal Components Analy-sis (PCA), of the niche-breadth of river macrophyte species in southern tropical Africa, may predicttheir larger-scale biogeographical range.

Undervalued Ecosystems: Ponds Boost Regional Macrophyte Diversity

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Ponds—depressional wetlands with ≤ 2 ha—are largely undervalued worldwide, despite serving as crucial diversity reservoirs. However, the extent to which ponds support diversity at the landscape scale is still underappreciated. Here, we investigate the contributions of ponds to macrophyte beta and gamma diversity in a subtropical wetland ...

Wiki-keys for the ferns of the Flora of Equatorial Guinea [PDF]

open access: yes, 2010
Flora of Equatorial Guinea is a research project coordinated by the Real Jardín Botánico of Madrid with the aim to produce a modern Flora for this almost unknown territory. One of our goals is to develop the website www. floradeguinea.com. A system of

New records, nomenclatural changes, and taxonomic notes for select North American leaf beetles (Coleoptera: Chrysomelidae) [PDF]

open access: yes, 2001
New records, nomenclatural changes and taxonomic notes are presented for select North American leaf beetles (Coleoptera: Chrysomelidae). The following genera are newly recorded from the United States: Nesaecrepida Blake, 1964; Acallepitrix Bechyne, 1959;

Drivers of Hirola Antelope Diet Selection in Natural and Managed Habitat in Eastern Kenya

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Hirola (Beatragus hunteri) populations in eastern Kenya consumed 17 forage species, favoring the grass Chloris virgata and the forbs Commelina benghalensis and C. diffusa. Nutrient analyses showed that natural habitats offered higher phosphorus, magnesium, and digestibility, whereas managed sites provided more sodium, potassium, and crude protein, with

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.
