Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Preliminary study of the pollination syndromes in a fragment of the Caatinga, in PE, Brazil

open access: yesBiotemas, 2016
The aim of this study was to preliminarily identify the pollination syndromes of plant species in a fragment of the Caatinga, in the municipality of Serrita, Pernambuco, Brazil. A floristic survey was conducted during March 2014 in a 900 m² area.

Evidence for moth pollination in a rhinomyiophilous Erica species from the Cape Floristic Region of South Africa [PDF]

open access: yesPhytoKeys
Contrasting pollination syndromes in closely related species suggest that floral trait divergence is associated with differences in pollination system, but empirical observations are required to confirm syndrome-based predictions.

Reproductive biology and nectar secretion dynamics of Penstemon gentianoides (Plantaginaceae): a perennial herb with a mixed pollination system? [PDF]

open access: yesPeerJ, 2017
Background In many plant species, pollination syndromes predict the most effective pollinator. However, other floral visitors may also offer effective pollination services and promote mixed pollination systems.

Vascular flora in dry-shrub and wet grassland Cerrado seven years after a fire, Federal District, Brasil [PDF]

open access: yes, 2013
Studies of temporal dynamics for grassland sites report that fire suppression plays a crucial role in floristic changes. The objective of this study was to verify whrther after seven years without fire, communities showed variations in terms of ...

Nectary size is a pollination syndrome trait in Penstemon [PDF]

open access: yesNew Phytologist, 2019
Summary Evolution of complex phenotypes depends on the adaptive importance of individual traits, and the developmental changes required to modify traits. Floral syndromes are complex adaptations to pollinators that include color, nectar, and shape variation.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Effect of climate, anther morphology and pollination syndrome on pollen availability in Penstemon

open access: yesJournal of Pollination Ecology, 2023
Traditionally, pollen presentation is thought to be a function of pollinator type and visitation frequency. However, despite the repeated observation that pollen presentation is influenced by flower morphology and abiotic factors, these aspects have been

β-Ocimene, a key floral and foliar volatile involved in multiple interactions between plants and other organisms [PDF]

open access: yes, 2017
β-Ocimene is a very common plant volatile released in important amounts from the leaves and flowers of many plant species. This acyclic monoterpene can play several biological functions in plants, by potentially affecting floral visitors and also by ...
