  • Leading-edge vortices over swept-back wings with varying sweep geometries. [Journal Article]
    R Soc Open Sci. 2019 Jul; 6(7):190514.Lambert WB, Stanek MJ, … Hackett EE
  • Micro air vehicles are used in a myriad of applications, such as transportation and surveying. Their performance can be improved through the study of wing designs and lift generation techniques including leading-edge vortices (LEVs). Observation of natural fliers, e.g. birds and bats, has shown that LEVs are a major contributor to lift during flapping flight, and the common swift (Apus apus) has …
  • Artificial Light at Night Promotes Activity Throughout the Night in Nesting Common Swifts (Apus apus). [Journal Article]
    Sci Rep. 2019 07 30; 9(1):11052.Amichai E, Kronfeld-Schor N
  • The use of artificial light at night (ALAN) is a rapidly expanding anthropogenic effect that transforms nightscapes throughout the world, causing light pollution that affects ecosystems in a myriad of ways. One of these is changing or shifting activity rhythms, largely synchronized by light cues. We used acoustic loggers to record and quantify activity patterns during the night of a diurnal bird …
  • Mitochondrial genome diversity and evolution in Branchiopoda (Crustacea). [Journal Article]
    Zoological Lett. 2019; 5:15.Luchetti A, Forni G, … Mantovani B
  • CONCLUSIONS: Branchiopod mitogenomes appear rather well-conserved, although gene rearrangements have occurred. For the first time, it is reported a putative non-homologous recombination event involving a mitogenome, which produced a pseudogenic tRNA sequence. In addition, in line with data in the literature, we explain the higher substitution rate of Anostraca and Onychocaudata with the inferred GC substitution bias that occurred during their evolution.
  • Gliding for a free lunch: biomechanics of foraging flight in common swifts (Apus apus). [Journal Article]
    J Exp Biol. 2018 11 19; 221(Pt 22)Hedrick TL, Pichot C, de Margerie E
  • Although the biomechanics of animal flight have been well studied in laboratory apparatus such as wind tunnels for many years, the applicability of these data to natural flight behaviour has been examined in few instances and mostly in the context of long-distance migration. Here, we used rotational stereo-videography to record the free-flight trajectories of foraging common swifts. We found that…
  • Morphology and morphometry of Haemonchus contortus exposed to Gigantochloa apus crude aqueous extract. [Journal Article]
    Vet World. 2018 Jul; 11(7):921-925.Widiarso BP, Kurniasih K, … Nurcahyo W
  • CONCLUSIONS: G. apus crude aqueous extract activity revealed morphology change such as cervical papillae, vulvar flab, gubernaculum, posterior end, and reduced morphometry measurement of H. contortus adult worms, notably in body length, body width, cervical papillae width, gubernaculum, and spicule length in males and body length, body width, cervical papillae width, and vulva length in females.
  • Hydrolytic pre-treatment methods for enhanced biobutanol production from agro-industrial wastes. [Journal Article]
    Bioresour Technol. 2018 Feb; 249:673-683.Maiti S, Gallastegui G, … Soccol CR
  • Brewery industry liquid waste (BLW), brewery spent grain (BSG), apple pomace solid wastes (APS), apple pomace ultrafiltration sludge (APUS) and starch industry wastewater (SIW) have been considered as substrates to produce biobutanol. Efficiency of hydrolysis techniques tested to produce fermentable sugars depended on nature of agro-industrial wastes and process conditions. Acid-catalysed hydroly…
  • The leading-edge vortex of swift wing-shaped delta wings. [Journal Article]
    R Soc Open Sci. 2017 Aug; 4(8):170077.Muir RE, Arredondo-Galeana A, Viola IM
  • Recent investigations on the aerodynamics of natural fliers have illuminated the significance of the leading-edge vortex (LEV) for lift generation in a variety of flight conditions. A well-documented example of an LEV is that generated by aircraft with highly swept, delta-shaped wings. While the wing aerodynamics of a manoeuvring aircraft, a bird gliding and a bird in flapping flight vary signifi…
  • Extension of the Avian Host Range of Collyriclosis in Europe. [Journal Article]
    J Wildl Dis. 2017 04; 53(2):344-348.Tahas SA, Diakou A, … Literák I
  • We describe cases of collyriclosis in apodiform and passeriform birds in Portugal, Switzerland, and Germany. We extend the host range of Collyriculm faba to include apodiform birds (Apus apus , Apus melba , and Apus pallidus) and the passerine Sitta europaea (Eurasian Nuthatch). Infections varied in severity from an incidental finding to severe debilitation and death. The infection route remains …
  • Annual 10-Month Aerial Life Phase in the Common Swift Apus apus. [Journal Article]
    Curr Biol. 2016 11 21; 26(22):3066-3070.Hedenström A, Norevik G, … Åkesson S
  • The common swift (Apus apus) is adapted to an aerial lifestyle, where food and nest material are captured in the air. Observations have prompted scientists to hypothesize that swifts stay airborne for their entire non-breeding period [1, 2], including migration into sub-Saharan Africa [3-5]. It is mainly juvenile common swifts that occasionally roost in trees or buildings before autumn migration …
  • Vulnerability of Subarctic and Arctic breeding birds. [Journal Article]
    Ecol Appl. 2017 01; 27(1):219-234.Hof AR, Rodríguez-Castañeda G, … Nilsson C
  • Recent research predicts that future climate change will result in substantial biodiversity loss associated with loss of habitat for species. However, the magnitude of the anticipated biodiversity impacts are less well known. Studies of species vulnerability to climate change through species distribution models are often limited to assessing the extent of species' exposure to the consequences of …
  • Water Use Patterns of Four Tropical Bamboo Species Assessed with Sap Flux Measurements. [Journal Article]
    Front Plant Sci. 2015; 6:1202.Mei T, Fang D, … Hölscher D
  • Bamboos are grasses (Poaceae) that are widespread in tropical and subtropical regions. We aimed at exploring water use patterns of four tropical bamboo species (Bambusa vulgaris, Dendrocalamus asper, Gigantochloa atroviolacea, and G. apus) with sap flux measurement techniques. Our approach included three experimental steps: (1) a pot experiment with a comparison of thermal dissipation probes (TDP…
  • Variable responses of human and non-human primate gut microbiomes to a Western diet. [Journal Article]
    Microbiome. 2015 Nov 16; 3:53.Amato KR, Yeoman CJ, … Leigh SR
  • CONCLUSIONS: These results suggest that the human gut microbiota has unique properties that are a result of changes in human diet and physiology across evolution or that may have contributed to the evolution of human physiology. Therefore, the role of animal models for understanding the relationship between the human gut microbiota and host metabolism must be re-focused.
  • BowMapCL: Burrows-Wheeler Mapping on Multiple Heterogeneous Accelerators. [Journal Article]
    IEEE/ACM Trans Comput Biol Bioinform. 2016 Sep-Oct; 13(5):926-938.Nogueira D, Tomas P, Roma N
  • The computational demand of exact-search procedures has pressed the exploitation of parallel processing accelerators to reduce the execution time of many applications. However, this often imposes strict restrictions in terms of the problem size and implementation efforts, mainly due to their possibly distinct architectures. To circumvent this limitation, a new exact-search alignment tool (BowMapC…
  • Mercury concentrations in feathers of Common Swifts (Apus apus). [Journal Article]
    Berl Munch Tierarztl Wochenschr. 2015 Jul-Aug; 128(7-8):340-4.Legler M, Leonhard W, … Kummerfeld N
  • Mercury (Hg) has been well studied as a bioaccumulated contaminant in aquatic ecosystems worldwide. It has been found to have negative effects on carnivorous and piscivorous bird species with the highest Hg concentrations at the top of the food chain. The objective of this study was to increase our knowledge of mercury exposure in insectivorous birds, especially in a species of the family Apodida…
  • The whole mitochondrial genome of the Lesser Kestrel (Falco naumanni). [Journal Article]
    Mitochondrial DNA A DNA Mapp Seq Anal. 2016 07; 27(4):2385-6.Wang HW, Zhang HF, … Wang KH
  • Falconiformes include most of the predatory birds, they play crucial role in maintaining the balance of ecology system. To further illustrate the phylogenetic status for the species of Falconiformes, the entire mitochondrial DNA (mtDNA) genome of Falco naumanni was amplified and sequenced, further phylogenetic analysis was performed by incorporating with other 8 entire mtDNA genomes representing …
