Forest seed dispersal by carnivores in temperate forests and dry tropical forests [PDF]

, 2020
The mechanisms of forest seed dispersal and regeneration of various altered forest ecosystems are complemented by the action of carnivores. The objective of this study was to evaluate the role of endozoochoric and diploendozoochoric mammals in the dispersal, scarification, and germination of seeds in two different forest ecosystems: temperate forest ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Germination responses of a dry sclerophyll forest soil-stored seedbank to fire related cues [PDF]

, 2013
Fire is an integral component of many ecosystems worldwide. Many plant species require fire-related cues, primarily heat and smoke, to trigger germination. Despite the importance of this process, the responses of many Australian species to these cues are

Seed banking in ancient forest species: why total sampled area really matters

, 2012
This study investigates how methodological aspects of seed-bank sampling affect seed-bank records in temperate deciduous forests. We focused explicitly on seed-bank records of ancient forest species, which are assumed to lack a persistent seed bank; a ...

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

Advanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.
