Ecology and Evolution, Volume 15, Issue 9, September 2025.This paper analyzed the evolutionary potential of Ipomoea cavalcantei (an endemic species from the Amazon) by using floral integration and phenotypic selection analysis. The analyzed population presented floral integration in style length, probably due to selective pressures from pollinators on floral traits related to pollen deposition.

Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars
International Journal of Horticultural Science, 2010 Fruit set of five sour cherry cultivars (‘Újfehértói fürtös’, ‘Éva’, ‘Petri’, ‘Pándy 279‘ and ‘Csengôdi’) of eight years-old trees grown in Újfehértó, located in the Eastern north part of Hungary have been studied over two years (2008 & 2009).

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Reproductive biology of the threatened species Furcraea parmentieri (Aspargaceae)
Botanical Sciences, 2017 Background: Reproductive traits are features of a species’ biology that may determine its rarity, as they affect its genetic diversity and structure, as well as its population dynamics.

Size and the Not-So-Single Sex: Disentangling the Effects of Size and Budget on Sex Allocation in Hermaphrodites [PDF]
, 2004 Sex allocation theory explains how size-related variations in male and female fitness may favor the evolution of size-dependent sex allocation in hermaphrodites.

New Phytologist, Volume 247, Issue 6, Page 2733-2745, September 2025.Summary The evolution of dioecy from hermaphroditism is widely thought to be a response to disruptive selection favoring males and females, driven by advantages of inbreeding avoidance, sexual specialization, or both. It has hitherto been difficult to uncouple the importance of these two hypotheses.

Large pollen loads of a South African asclepiad do not interfere with the foraging behaviour or efficiency of pollinating honey bees [PDF]
, 2012 The pollen of asclepiads (Asclepiadoideae, Apocynaceae) and most orchids (Orchidaceae) are packaged as large aggregations known as pollinaria that are removed as entire units by pollinators.

Oikos, Volume 2025, Issue 8, August 2025.Interspecific pollen transfer (IPT), the pollen movement between plant species via shared pollinators, reduces the reproductive success of pollen‐recipient plants due to hybridization with heterospecific pollen grains. As a result, IPT hinders coexistence of sympatric, co‐flowering species by reducing their reproductive success.

Scientia Agricola, 2011 Although canola, (Brassica napus L.), is considered a self-pollinating crop, researchers have indicated that crop productivity increases as a result of honey bee Apis mellifera L. pollination.
