Evaluating the success of functional restoration after reintroduction of a lost avian pollinator. [PDF]

Conserv Biol, 2022
Abstract Conservation translocation is a common method for species recovery, for which one increasingly frequent objective is restoring lost ecological functions to promote ecosystem recovery. However, few conservation translocation programs explicitly state or monitor function as an objective, limiting the ability to test assumptions, learn from past ...

Decay stages of Jurassic wood debris from Scotland: evidence for the coevolution of fungal rot, arthropods and the nurse log strategy. [PDF]

New Phytol
Summary A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed ‘nurse logs’.

Embryo excision in Compositae, with implications for combating biodiversity loss. [PDF]

Appl Plant Sci
Abstract Premise Embryo excision is an effective, under‐described means of promoting germination in the sunflower family and may help to ensure the survival of endangered taxa or lineages with limited seed availability. Methods and Results We describe and illustrate a detailed method of embryo excision used successfully to stimulate germination in a ...

Can heterosis and inbreeding depression explain the maintenance of outcrossing in a cleistogamous perennial?

American Journal of Botany, Volume 110, Issue 10, October 2023., 2023
Abstract Premise What maintains mixed mating is an evolutionary enigma. Cleistogamy—the production of both potentially outcrossing chasmogamous and obligately selfing cleistogamous flowers on the same individual plant—is an excellent system to study the costs of selfing.

Precipitation timing and soil substrate drive phenology and fitness of Arabidopsis thaliana in a Mediterranean environment

Functional Ecology, Volume 37, Issue 9, Page 2471-2487, September 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract In Mediterranean climates, the timing of seasonal rains determines germination, flowering phenology and fitness. As climate change alters seasonal precipitation patterns, it is important to ask how these changes will affect the phenology and fitness of plant populations.

Linking animal behaviour and tree recruitment: Caching decisions by a scatter‐hoarder corvid determine seed fate in a Mediterranean agroforestry system

Journal of Ecology, Volume 111, Issue 2, Page 400-411, February 2023., 2023
The consequences of seed caching for seedling early establishment are driven by a fine decision‐making process of the disperser. Magpies seemed to ponder the characteristics of the habitat and the seed itself to determine where and how to cache each nut. By doing so, magpies reinforced the quality of seed dispersal effectiveness, as they cached walnuts

Top‐down cascading effects of seed‐feeding beetles and their parasitoids on plants and leaf herbivores

Functional Ecology, Volume 36, Issue 6, Page 1500-1512, June 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract When feeding on a plant, herbivorous insects alter the quality of the plant as a food source. This affects other organisms interacting with the same plant. These so‐called ‘plant‐mediated interactions’ can be altered by parasitoids that attack the herbivores.

Seed fate in ant‐mediated dispersal: Seed dispersal effectiveness in the Ectatomma ruidum (Formicidae)—Zanthoxylum ekmanii (Rutaceae) system

Biotropica, Volume 54, Issue 3, Page 764-775, May 2022., 2022
Using the seed dispersal effectiveness framework, we tracked seed fate in a dispersal limited system finding that ant workers (Formicidae, Ectatomma ruidum) act as secondary dispersers for the pioneer tree Zanthoxylum ekmanii (Rutaceae) whose seeds have no visible adaptation for ant dispersal.

Recruitment limitation in three large‐seeded plant species in a tropical moist forest

Biotropica, Volume 54, Issue 2, Page 418-430, March 2022., 2022
Recruitment limitation results from three mechanisms: (i) lack of seed sources (i.e., source limitation), (ii) failure of available seeds to reach recruitment sites (i.e., dispersal limitation), and (iii) failure of arrived seeds to establish at a location (i.e., establishment limitation).
