Fungal graviresponses: Physiological and molecular insights from tissue reorientation in the gravity vector

Mycology
Graviresponses, the growth responses of organisms to gravitational alterations, are pivotal yet understudied phenomena in fungi compared to plants and animals.

Spore dispersal of Eutypella species under desert grape-growing conditions of southern California

Phytopathologia Mediterranea, 2020
The seasonal abundance of Diatrypaceae spores was studied in southern California’s desert table grape-growing region of Coachella Valley. Glass microscope slides covered with petroleum jelly were placed in a mature cv.

Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms

Ecology and Evolution, 2021
Bird‐mediated dispersal is presumed to be important in the dissemination of many different types of organisms, but concrete evidence remains scarce. This is especially true for biota producing microscopic propagules.

Shaping research in marine functional connectivity for integrated and effective marine science and management

Biological Reviews, EarlyView.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...

Spore dispersal in a barley crop: A mathematical model

Agricultural Meteorology, 1979
Abstract The paper describes a two-dimensional model of the movement and deposition of fungal spores within and above a barley crop. The model is tested against experimental measurements of spores of barley mildew, Erisyphe graminis, downwind of a narrow strip of infection, and of Lycopodium spores downwind of a line of point sources at crop height ...

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Extreme functional specialization of fertile leaves in a widespread fern species and its implications on the evolution of reproductive dimorphism

Ecology and Evolution
Resource allocation theory posits that organisms distribute limited resources across functions to maximize their overall fitness. In plants, the allocation of resources among maintenance, reproduction, and growth influences short‐term economics and long ...

Cover crops can mitigate effects on grape pathogen dispersal [PDF]

, 2020
Different kind of ground covers has been indicated as an efficient way to limit rain-splashed dispersal of disease-causing spores in several crops, but not in vineyards.

Fragments of the earliest land plants [PDF]

, 2003
The earliest fossil evidence for land plants comes from microscopic dispersed spores. These microfossils are abundant and widely distributed in sediments, and the earliest generally accepted reports are from rocks of mid-Ordovician age (Llanvirn, 475 ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
