High-speed video analysis of wing-snapping in two manakin clades (Pipridae: Aves).
Basic kinematic and detailed physical mechanisms of avian, non-vocal sound production are both unknown. Here, for the first time, field-generated high-speed video recordings and acoustic analyses are used to test numerous competing hypotheses of the kinematics underlying sonations, or non-vocal communicative sounds, produced by two genera of Pipridae, Manacus and Pipra (Aves). Eleven behavioral...
متن کاملMorphological and phylogenic analysis of Fusarium species associated with vertical system of Orobanche spp.
Broomrapes (Orobanche spp.) are parasitic weeds and considered as a major limiting factor for the cultivation of various crops in many parts of the world. Due to the special biology of broomrape, including seed production, dispersal and longevity, the control of these species are often extremely difficult. Broomrape poses a serious threat to Iran’s agriculture; therefore exploring potential bio...
متن کاملIsolation and characterization of microsatellite loci in the blue manakin, Chiroxiphia caudata (Aves, Pipridae)
We designed primers for amplifying 11 polymorphic microsatellite loci in the blue manakin, Chiroxiphia caudata , a neotropical passerine bird which inhabits a critically endangered tropical ecosystem, the Brazilian Atlantic forest. Based on genotypes from 24 individuals from a single population, we detected between four and 22 alleles per locus with observed heterozygosities ranging from 0.54 t...
متن کاملLight drives vertical gradients of leaf morphology in a sugar maple (Acer saccharum) forest.
Leaf mass per area (LMA, g m(-2)) is an essential trait for modeling canopy function due to its strong association with photosynthesis, respiration and leaf nitrogen. Leaf mass per area, which is influenced by both leaf thickness and density (LMA = thickness × density), generally increases from the bottom to the top of tree canopies, yet the mechanisms behind this universal pattern are not yet ...
متن کاملA New Hybrid Manakin {dixiphia Pipra X Pipra Fiucavda) (aves: Pipridae) from the Andean Foothills of Eastern Ecuador
—A new intergeneric hybrid manakin (Dtxiphia pipra x pipra fiiicauda) is described from the Andean foothills of eastern Ecuador. The adult male specimen represents ihe first record of hybridization among species belonging to different clades of the traditional but polyphyletic genus Pipra (Prum 1990, 1992). The collecting locality, Sarayacu (l°44'S. 77°29"W). apparently lies in a narrow zone of...
