Environmental DNA (eDNA) holds great promise for conservation applications like the monitoring of invasive or imperiled species, yet this emerging technique requires ongoing testing in order to determine contexts over which it is effective. For example, little research date has evaluated how seasonality organism behavior activity may influence detection probability eDNA. We applied eDNA survey two highly species endemic upper Black Warrior River basin Alabama, US: Waterdog (Necturus...
The Orinoco Andes and northwestern Guiana Shield (Essequibo, Orinoco, Branco, upper Negro) were found to contain 11 species of Ancistrus, six which are new. We additionally examine A. brevifilis from the Río Tuy Venezuela trinitatis island Trinidad. in region can be broken up into dorsoventrally flattened (A. leoni new species, lithurgicus, macropthalmus), white yellow-dotted kellerae nudiceps, patronus species), wide-jawed amaris yutajae white-spotted brevifilis, leucostictus, trinitatis,...
Modern zoos and aquariums aspire to contribute significantly biodiversity conservation research. For example, research is a key accreditation criterion of the Association Zoos Aquariums (AZA). However, no studies date have quantified this contribution. We assessed productivity 228 AZA members using scientific publications indexed in ISI Web Science (WoS) database between 1993 2013 (inclusive). published 5175 peer-reviewed manuscripts over period, with publication output increasing time. Most...
Since 2000, collaborative and multidisciplinary field inventories have helped quadruple park coverage in Peru’s richest region.
The Guiana Shield in northeastern South America contains some of the largest tracts intact forests on globe. Guyana alone has more than 80% forest cover. In south-central a unique biogeographic feature allows for hydrological connection between with Amazon basin via Rupununi savannas and wetlands (Rupununi Portal). This corridor connectivity two most biodiverse, carbon rich world. significance this (and other) corridors terrestrial aquatic species are underappreciated scientific literature....
Hypostomus macushi is described as a new species of the H. cochliodon group based on presence light background with widely separated black spots. The only members similar coloration are cochliodon, H.ericae, ericius and paucipunctatus. can be from by lacking longitudinal ridge pterotic-supracleithrum lack dark stripes; keels formed sharp odontodes lateral plates; ericae paucipunctatus buccal papilla; having spots in distal dorsal caudal fins not combining (vs. to form wavy lines); medium...
ABSTRACT A new species of Panaqolus is described from material the Takutu River and mainstem rio Branco. The diagnosed congeners by its color pattern consisting dark light bars on body, bands fins, with dots vermiculations absent (vs. no in P. albomaculatus , nix nocturnus koko vs. fins unbanded dentex present albivermis maccus ). barred specific bar number orientation head, oriented a anteroventral-posterodorsal direction anterodorsal-posteroventral gnomus ), having consistently 5 (n = 4)...
Guyana, located in northern South America north of Brazil between Venezuela and Suriname, includes portions the Orinoco, Amazon, Courantyne river basins, a majority Essequibo River Basin, all Berbice Demerara basins. Partly as consequence historical contemporary drainage complexity, Guyana has remarkably diverse freshwater fish fauna. Here, we compile first comprehensive list Guyana's fishes, totaling some 657 species-level taxa (97 records, 117 endemics at least three introduced species),...
The application of environmental DNA (eDNA) methods to simultaneously study vertebrate diversity holds promise accelerate conservation efforts, especially in freshwater systems which are among the most imperiled world. Here, using eDNA sampling, we identify patterns biodiversity across different habitats Kankakee River watershed, one diverse lotic Illinois, USA. Our metabarcoding analyses identified 147 taxa, including 77 fishes, 38 birds, 24 mammals, five amphibians and three reptiles at 11...
O presente trabalho tem como objetivo explorar a utilização da Tabuada Pitagórica material didático, com vistas para as aulas de Matemática na formação pedagogos. Com isso, iremos relatar uma experiência ao implementar inicial Esse se trata pesquisa maior, um conclusão curso graduanda do Licenciatura em Matemática. Para tanto, tivemos participantes 28 estudantes Pedagogia universidade pública estado Paraná. Como resultado percebemos que inicialmente muitos dos não tinham conhecimento sobre...
A anemia falciforme é causada pela modificação fisicoquímica da hemoglobina Hemoglobina S que em condição de hipóxia adquire forma foice, fazendo com sua circulação não seja adequada, gerando a obstrução do fluxo sanguíneo na macro e microcirculação. sanguínea falcização das hemácias afetam os tecidos cavidade oral causando isquemia necrose nos ossos face, desenvolvendo osteomielite, pulpites, calcificações pulpares, morte pulpar, mucosas pálidas, periodontite grau incomum, dentes esmalte...
A new species of Cetopsorhamdia is described from material collected on rapid inventories and ichthyological expeditions in the Amazon region Peru, Ecuador Colombia. The can be differentiated all other by colouration pattern fins, number vertebrae, ribs, level insertion dorsal fin, rays pectoral osteological characters several morphometric characters. distributed along tributaries upper River basin Colombia Ecuador.
Hemiancistrus cerrado is described from the tributaries of rio Araguaia, Tocantins basin. has external similarities with H. megalopteryx and punctulatus coastal streams southern Brazil, can be distinguished by having a larger internarial width, 15.9-21.1% head length (vs. 11.2-14.0% in 11.2-13.9% punctulatus) and, little overlap, adipose-fin spine length, 9.4-13.6% standard 7.1-8.7% 7.4-10.0% punctulatus). further differs pectoral-fin reaching maximally to middle pelvic-fin when adpressed...
