Evaluation of the symmetric effect of antagonists in the floral morphs of the distylic shrub Bouvardia ternifolia: a field study

open access: yesBotan‪ical Sciences, 2018
Background: Heterostyly is a genetic polymorphism characterized by a system of sporophyte auto-incompatibility in which the plant populations show two (distyly) or three (tristyly) floral morphs.

Ruminal microbiota–host interaction and its effect on nutrient metabolism

open access: yesAnimal Nutrition, 2021
Rumen microbiota has a close and intensive interaction with the ruminants. Microbiota residing in the rumen digests and ferments plant organic matters into nutrients that are subsequently utilized by the host, making ruminants a unique group of animals ...

Analysis and Assembling of Network Structure in Mutualistic Systems [PDF]

open access: yes, 2007
It has been observed that mutualistic bipartite networks have a nested structure of interactions. In addition, the degree distributions associated with the two guilds involved in such networks (e.g.

Evolution of Plant–Animal Interactions [PDF]

open access: yes, 2010
The evolution of plant–animal interactions goes back to the Early Archean, when the first signals of photosynthesis may have been detected in the Isua Peninsula in Greenland, a phenomenon that is related to the isotopic anomalies of carbon.

Geographic patterns in plant-pollinator mutualistic networks [PDF]

open access: yes, 2002
. Recent reviews of plant–pollinator mutualistic networks showed that gen- eralization is a common pattern in this type of interaction. Here we examine the ecological correlates of generalization patterns in plant–pollinator networks, especially how ...

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

open access: yes, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Role of epigenetics in regulating defense mechanisms [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2019
Objective Epigenetics contains studying inheritable genetic variations that affect on gene expression pattern, but these variations do not create because of changes in DNA sequence. In addition, organisms are resistant to pathogens through some molecular

A global review on the role of small rodents and lagomorphs (clade Glires) in seed dispersal and plant establishment

open access: yesGlobal Ecology and Conservation, 2022
Zoochory is an ecologically and evolutionarily important seed dispersal type. The decline and extinction of seed-dispersing large herbivores severely threatens dispersal-driven ecosystem processes in many regions.

Changes in seed dispersal processes and the potential for between-patch connectivity for an arid land daisy [PDF]

open access: yes, 2012
Dispersal is a major and critical process in population biology that has been particularly challenging to study. Animals can have major roles in seed dispersal even in species that do not appear specifically adapted to animal-aided dispersal.
