Quantifying patch‐specific seed dispersal and local population dynamics to estimate population spread of an endangered plant species

open access: yesEcology and Evolution, 2021
Aim Habitat loss and fragmentation impose high extinction risk upon endangered plant species globally. For many endangered plant species, as the remnant habitats become smaller and more fragmented, it is vital to estimate the population spread rate of ...

Long Distance Seed Dispersal by Forest Elephants

open access: yesFrontiers in Ecology and Evolution, 2021
By dispersing seeds long distances, large, fruit-eating animals influence plant population spread and community dynamics. After fruit consumption, animal gut passage time and movement determine seed dispersal patterns and distances.

Pre-dispersal seed loss in two Prosopis species (Fabacea: Mimosoidea) from the Monte Desert, Argentina

open access: yesEcología Austral, 2018
Pre-dispersal flters imposed on the seed stage can alter the likelihood of seed dispersal. We evaluate pre-dispersal seed loss due to predation by insects and abortion in Prosopis flexuosa and P. chilensis. This study was conducted in two protected areas

Oilbirds disperse large seeds at longer distance than extinct megafauna

open access: yesScientific Reports, 2021
The extinction of megafauna in the Neotropics is thought to have reduced the potential of large seeds to be dispersed over long distances by endozoochory (ingestion by animals), but some seed dispersal systems have not been considered.

DNA fingerprinting validates seed dispersal curves from observational studies in the neotropical legume parkia. [PDF]

open access: yesPLoS ONE, 2012
Determining the distances over which seeds are dispersed is a crucial component for examining spatial patterns of seed dispersal and their consequences for plant reproductive success and population structure.

Seed Dispersal of an Invasive Shrub, Amur Honeysuckle (Lonicera maackii ), by White-tailed Deer in a Fragmented Agricultural-forest Matrix [PDF]

open access: yes, 2015
Ungulates are potentially important seed dispersers for many invasive plant species. While our understanding of which invasive plant species are dispersed by ungulates has improved over the last decade, the factors influencing this process remain poorly ...

EGFR‐STAT3 activation provides a therapeutic rationale for targeting aggressive ETV1‐positive prostate cancer

open access: yesMolecular Oncology, EarlyView.
Cotargeting EGFR and STAT3 with Erlotinib and TTI‐101 impairs both 2D and 3D growth of ETV1‐overexpressing prostate cancer cells by disrupting a self‐sustaining ETV1–EGFR positive feedback loop that promotes EGFR and STAT3 expression and phosphorylation (activation).

Between-site differences in the scale of dispersal and gene flow in red oak. [PDF]

open access: yesPLoS ONE, 2012
Nut-bearing trees, including oaks (Quercus spp.), are considered to be highly dispersal limited, leading to concerns about their ability to colonize new sites or migrate in response to climate change.

Seed dispersal in changing landscapes

open access: yesBiological Conservation, 2012
(Uploaded by Plazi for the Bat Literature Project) A growing understanding of the ecology of seed dispersal has so far had little influence on conservation practice, while the needs of conservation practice have had little influence on seed dispersal research.

Generalist birds promote tropical forest regeneration and increase plant diversity via rare-biased seed dispersal.

open access: yesEcology, 2016
Regenerated forests now compose over half of the world's tropical forest cover and are increasingly important as providers of ecosystem services, freshwater, and biodiversity conservation.
