Modelling stomatal mechanics: a critical review

open access: yesNew Phytologist, EarlyView.
Summary The biomechanics of stomatal movements have fascinated scientists for almost 150 yr, yet we still lack a conclusive and coherent mechanistic understanding of the process. In this review, we present a framework that allows critical insight into the state of knowledge of stomatal biomechanics, with a focus on modelling approaches.

A new Unidentified Far Infrared Band in NGC7027 [PDF]

open access: yes, 2004
We report on the detection of a molecular band centered at ~98 um (~102 cm^-1), observed with the Infrared Space Observatory in the young Planetary Nebula NGC7027.

Testing macroevolutionary predictions of the Grant‐Stebbins model in the origin of Aeschynanthus acuminatus

open access: yesNew Phytologist, EarlyView.
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

Disentangling phase transitions and critical points in the proton–neutron interacting boson model by catastrophe theory

open access: yesPhysics Letters B, 2014
We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions.

Variation in herbivore defense strategies among plant species differing in elevational distribution and the role of temperature in defense

open access: yesNew Phytologist, EarlyView.
Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

Sub-arcsecond CO(1-0) and CO(2-1) observations of the ultraluminous infrared galaxy IRAS 10190+1322

open access: yes, 2007
We present the results of high resolution mapping of the CO(1-0) and CO(2-1) emission of the ultraluminous infrared galaxy (ULIRG) IRAS 10190+1322, with the IRAM interferometer, down to an angular resolution of ~0.3 arcsec. This object is composed of two

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

High-resolution study of a star-forming cluster in the Cep-A HW2 region

open access: yes, 2007
Due to its relatively small distance (725 pc), the Cepheus A East star-forming region is an ideal laboratory to study massive star formation processes.

A new infrared band in the Interstellar and Circumstellar Clouds: C_4 or C_4H? [PDF]

open access: yes, 2002
We report on the detection with the Infrared Space Observatory (ISO) of a molecular band at 57.5 microns (174 cm^{-1}) in carbon-rich evolved stars and in Sgr B2.
