Unravelling the mystery of red flowers in the Mediterranean Basin: How to be conspicuous in a place dominated by hymenopteran pollinators [PDF]

Functional Ecology, Volume 36, Issue 11, Page 2774-2790, November 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Red‐flowered species have traditionally been related to ornithophily, and the ‘bee avoidance’ hypothesis, that is, red flower colouration is a way to reduce visits from hymenopterans, has been proposed to explain this association.

How are pollination and seed dispersal modes in Cerrado related to stratification? Trends in a cerrado sensu stricto woodland in southeastern Brazil, and a comparison with Neotropical forests

Acta Botânica Brasílica, 2018
A comprehensive census of a hectare of cerrado s.s. in southeastern Brazil, a small-tree and scrub woodland physiognomy, allowed the evaluation of whether pollination and dispersal modes are correlated with the stratification of the vegetation and if so,

Bird‐flower colour on islands supports the bee‐avoidance hypothesis

Functional Ecology, Volume 38, Issue 3, Page 600-611, March 2024., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many insular plant species inhabiting different archipelagos worldwide present typical ornithophilous floral traits (e.g. copious nectar, red‐orange colours), but most of them are visited by insectivorous/granivorous birds and lizards, which act as generalist ...

The community of hummingbirds (Aves: Trochilidae) and the assemblage of flowers in a Caatinga vegetation [PDF]

Brazilian Journal of Biology, 2012
We studied hummingbirds and their food plants in an area of caatinga vegetation. We specifically examined their seasonal use of this habitat, migratory and non-migratory status, their foraging strategies and community roles The study was conducted in an ...

Preliminary study of the pollination syndromes in a fragment of the Caatinga, in PE, Brazil

Biotemas, 2016
The aim of this study was to preliminarily identify the pollination syndromes of plant species in a fragment of the Caatinga, in the municipality of Serrita, Pernambuco, Brazil. A floristic survey was conducted during March 2014 in a 900 m² area.

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator-prey conflict within the carnivorous Pinguicula subgenus Temnoceras. [PDF]

Am J Bot
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Testing macroevolutionary predictions of the Grant-Stebbins model in the origin of Aeschynanthus acuminatus. [PDF]

New Phytol
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

Climate Change, Air Quality, and Pollen Allergies-State of the Art and Recommendations for Research and Public Health. [PDF]

Allergy
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,

Floral Integration and Phenotypic Selection on Floral Traits of <i>Ipomoea cavalcantei</i> (Convolvulaceae), a Rare, Endemic, and Endangered Species to the Amazon Ironstone Outcrops. [PDF]

Ecol Evol
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.

Untangling biodiversity interactions: A meta network on pollination in Earth's most diverse tropical savanna. [PDF]

Ecol Evol
We addressed how pollination meta network with vertebrate and invertebrate species is assembled in the world's most diverse savanna and identified potential biogeographical bias within the region. We found a generalization of interactions at the meta network level but a high degree of specialization within the modules, where bees are the module ...
