Ultrastructure and cytochemistry of squamulae intravaginales of the marine angiosperm, Halophila ovalis

open access: yesSouth African Journal of Botany, 1990
Small delicate structures found in the leaf bases in vegetative buds of the marine angiosperm Halophila ovalis (R. Br.) Hook. f. showed a fine structure of the component cells typical of secretory cells. They are rich in organelles particularly ER, dictyosomes, ribosomes and mitochondria. Endoplasmic reticulum occurs at two localities in each cell, one

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

open access: yesJournal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.

Evolutionary legacies structure the geography of seagrass traits across the world's oceans

open access: yesNew Phytologist, EarlyView.
Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

Synchronized anthesis and predation on pollen in the marine angiosperm Thalassia testudinum (Hydrocharitaceae) [PDF]

open access: yesMarine Ecology Progress Series, 2008
Synchrony in the anthesis of male and female flowers of the hydrophilous dioecious marine angiosperm Thalassia testudinum was studied by following flower buds of 64 staminate and 34 carpellate flowers in situ during night and day to observe the timing of flower opening.

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

A new conifer record from the late Aptian of La Paja Formation from Veléz, Santander (Colombia)

open access: yesActa Palaeobotanica
A new plant assemblage from the La Paja Formation at the Los Guayabos section of Vélez, Santander (Central Colombia) is described here. Based on ammonite biostratigraphy, the age of the flora is estimated as late Aptian.
