TLDR
Although it appears that bright plumage increases access to higher quality mates, age also plays a central role in determining a male's overall reproductive success because of the high levels of sexual promiscuity exhibited by the red‐backed fairy‐wren.
The pollen dispersal kernel and mating system of an insect-pollinated tropical palm, Oenocarpus bataua
TLDR
Characterise pollen movement for an insect-pollinated Neotropical canopy palm, Oenocarpus bataua, and relate these data to adult mating system and population genetic structure, and preliminary analyses suggest that these findings may be explained by a relatively diffuse spatial and temporal distribution of flowering trees.
GENOMIC AND MORPHOLOGICAL ANALYSIS OF A SEMIPERMEABLE AVIAN HYBRID ZONE SUGGESTS ASYMMETRICAL INTROGRESSION OF A SEXUAL SIGNAL
TLDR
The potential for sexual selection to erode taxonomic boundaries and promote gene flow, particularly at an intermediate stage of divergence, is highlighted in this study.
A Trans-Amazonian Screening of mtDNA Reveals Deep Intraspecific Divergence in Forest Birds and Suggests a Vast Underestimation of Species Diversity
TLDR
The results identify numerous genetically and phenotypically divergent lineages which may result in new species-level designations upon closer taxonomic scrutiny and thorough sampling, although lineages in the tropical region could be older than those in the temperate zone without necessarily representing separate species.
TEMPORAL AND SPATIAL PATTERNS OF MACAW ABUNDANCE IN THE ECUADORIAN AMAZON
Abstract Although macaws are arguably the most widely recognized species of bird from Neotropical rainforests, little is known of their basic biology or demography in the wild. In Ecuador, as in
Plumage color and reproduction in the red-backed fairy-wren: Why be a dull breeder?
TLDR
The results suggest that males may not reap any fitness benefits by breeding in dull coloration, compared with breeding in bright plumage, but rather may be constrained to breed in suboptimal plumage by the timing of plumage acquisition.
Extrapair Paternity and Sexual Selection in Socially Monogamous Birds: Are Tropical Birds Different?
TLDR
Conclusions regarding the role of EPP in sexual selection must be ta�en with a large and important caveat, the so-called “temperate zone bias”.
The effects of delayed plumage maturation on aggression and survival in male red-backed fairy-wrens
TLDR
The hypothesis that DPM is related to increased male survival in the red-backed fairy-wren via either female mimicry or status signaling is tested, indicating that male plumage coloration signals social status but that dull plumage does not afford a net survival advantage, perhaps because plumagecolor is a conditional strategy.
Female ornamentation in Malurus fairy-wrens: a hidden evolutionary gem for understanding female perspectives on social and sexual selection
TLDR
Phylogeographic analyses in combination with life-history data suggest that female plumage colouration and bill colouration are under active selection, independent of that experienced by males, in female fairy-wrens.
Impacts of forest fragmentation on orchid bee (Hymenoptera: Apidae: Euglossini) communities in the Chocó biodiversity hotspot of northwest Ecuador
TLDR
Forest fragments and continuous forest differed in both community composition and evenness, but not in abundance or species richness, so the conservation value of continuous forest for orchid bee diversity is underscored.
