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 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]
Conserv BiolAbstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

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

EFECTO DEL ESTRÉS HÍDRICO Y SALINO SOBRE LA GERMINACIÓN DE Atriplex nummularia (CHENOPODIACEAE) [PDF]
Acta Biológica Colombiana, 2013 Los suelos salinos, característicos de zonas áridas, pueden afectar la germinación de las especies por presentar bajos potenciales hídricos o por toxicidad iónica. En este trabajo se determinó el efecto del estrés hídrico y salino sobre la germinación de

EXPLORANDO EL PAPEL DE LA HORMIGA GENERALISTA SOLENOPSIS GEMINATA (FORMICIDAE: MYRMICINAE) EN LA GERMINACIÓN DE SEMILLAS DE SENNA SPECTABILIS (FABACEAE: CAESALPINIOIDEAE) [PDF]
Caldasia, 2012 La colonización de los potreros por especies vegetales diferentes a los pastos está limitada por la escasez de dispersores primarios y la poca disponibilidad de sitios adecuados para la germinación de las plantas.

Un modelo estocástico de germinación [PDF]
, 2020 Assuming that the germination process of a seed passes through several stages (or states), including a state of non-germination, we model this phenomenon by means of a continuous-time Markov chain. The distribution of the germination time and the average

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.

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.
