Abstract:
... Shape memory polymers can change their initial shape under the stimulation of the external environment, but most of the stimulations require not only an external force but also a high temperature, which limits their application to a certain extent. Inspired by the unmatched elongation of cells on both sides of the mimosa petiole in nature, which leads to leaf closure, we designed a new type of sha ...

Abstract:
... Our morphological study of the exocrine system in workers of Leptanilla clypeata revealed the presence of at least 23 glands. Among these, the dorsoproximal intramandibular gland represents a novel structure for social insects. Another novel gland may exist in the ventral part of the postpetiolus; both the petiole and postpetiole contain conspicuous clusters of large gland cells. The occurrence of ...

Abstract:
... PREMISE: The phenomenon called “diminishing returns” refers to a scaling relationship between lamina mass (M) vs. lamina area (A) in many species, i.e., M ∝ Aᵅ>¹, where α is the scaling exponent exceeding unity. Prior studies have focused on the scaling relationships between lamina dry mass (DM) and A, or between fresh mass (FM) and A. However, the scaling between petiole mass and M and A has seld ...

An increase in population density may result in the spatial and temporal heterogeneity of resources at scales smaller than an individual, inducing different modular responses at different positions of a plant, or architectural plasticity. To better understand how plants respond to density via architectural plasticity, we conducted a field experiment on an annual species, Abutilon theophrasti. Plan ...
