An exceptional new specimen (CAPPA/UFSM 0035) of Buriolestes schultzi was discovered during recent fieldwork at the type locality taxon, which is Carnian in age (Late Triassic). This early sauropodomorph peculiar owing to its faunivorous feeding habits, unusual amongst members this large omnivorous/herbivorous clade. The incorporates data on skeletal portions that have so far been unknown for B. schultzi, particularly regarding skull and axial skeleton. As such, now as complete best-known...
Predatory dinosaurs were an important ecological component of terrestrial Mesozoic ecosystems. Though theropod carried this role during the Jurassic and Cretaceous Periods (and probably post-Carnian portion Triassic), it is difficult to depict Carnian scenario, due scarcity fossils. Until now, knowledge on earliest predatory mostly relies herrerasaurids recorded in strata South America. Phylogenetic investigations recovered clade different positions within Dinosauria, whereas fewer studies...
Excavating sponges are one of the main groups bioeroders in coral reefs. Their diversity has been thoroughly studied some regions: Caribbean, Mediterranean, and Indo-Pacific, including Mexican Pacific. However, there is a lack information from Pacific Central America, with only few records Panama Costa Rica. This study provides additional distributional taxonomic descriptions species collected between 2011 2016 at nine localities along coast El Salvador, Nicaragua, Rica Panama. A total...
Aetosaurs are armored pseudosuchian archosaurs widespread in Upper Triassic units. In South America, four taxa were previously recorded: Aetosauroides scagliai, Neoaetosauroides engaeus, Aetobarbakinoides brasiliensis, and Chilenosuchus forttae. Herein we describe a new Late juvenile aetosaur from the Santa Maria Formation of southern Brazil, Polesinesuchus aurelioi gen. et sp. nov., increasing paleobiodiversity this interesting group to five Western Gondwana. The holotype is composed...
A new Permian temnospondyl from South America is described and considered to represent a species – Konzhukovia sangabrielensis sp. nov. of the genus previously recorded exclusively Russia. It consists anterior half partial right side skull roof palate. comprehensive phylogenetic analysis was performed with several archegosauroids other well-supported groups temnospondyls in order access affinities Brazilian test monophyly Archegosauroidea. Archegosauroidea not recovered as monophyletic...
Probainognathian cynodonts are conspicuous elements of the Assemblage Zones Triassic Santa Maria Supersequence in southern Brazil. Within this group, derived clade Prozostrodontia, which crown group Mammalia is included, taxonomic diverse Hyperodapedon and Riograndia AZs. We describe here second known specimen (CAPPA/UFSM 0123) Prozostrodon brasiliensis, until now only represented by its holotype. CAPPA/UFSM 0123 includes a right dentary with dentition. As holotype P. it has four lower...
Abstract Tapejarids are edentate pterosaurs recovered mainly from E arly C retaceous deposits. They diagnosed by five synapomorphies, among which only one is postcranial: a broad and well‐developed tubercle at the ventroposterior margin of coracoid. Regarding clade T halassodrominae, most phylogenetic studies based on cranial elements, as postcranial skeletons these rare. Here, new material R omualdo F ormation ( A ptian– lbian) raripe B asin described. The comprises three posteriormost...
Only recently, new ontogenetic series of early dinosaurs and related groups have been described. Here, we present an isolated immature dinosauriform femur from the Late Triassic southern Brazil investigate its influence on character polarization. Because specimen shares a number synapomorphies with Pampadromaeus barberenai, herein postulate that it corresponds to juvenile individual taxon. Accordingly, morphological variation between mature individuals P. barberenai. Scoring these states...
Central Chile is characterized by a Mediterranean Climate.Some of the tree species that grows in this zone (e.g.Quillaja saponaria (quillay) and Cryptocarya alba (peumo)) have developed physiological mechanisms to tolerate drought periods during summer.The aim study was quantify growth parameters two-year-old quillay peumo saplings, maintained under controlled water restricted conditions one summer season.The plants were assigned two different experimental treatments: well watered...
Abstract The paper describes a modification (RIPT2) of an earlier described, passive Rocky Intertidal Plankton Trap (RIPT1) to be used in exposed rocky shores. trap is light, simple build, easy install, and inexpensive. It aims evaluate integrate over time the mero- holoplankton arriving shore. A set 3 RIPT2 RIPT1 traps were tested, period days, on horizontal platform at El Eden, Antofagasta, Chile. RIPT-flowmeters permitted approximation rate water filtering, which was about times greater...
Abstract. The present study analyzes the distribution, population structure, biomass and morphological characteristics of intertidal tunicate Pyura stolonifera (Heller, 1878) in Bay Antofagasta, Chile, where species shows a reduced geographical range extending around 60 – 70 km. Three sites along its distribution were studied. At central site presents widest belts, reaching nearly 11 m (the mid‐intertidal‐ ‐zone higher percent cover). Population dry here averaged up to 20.45 kg·m –2 ,...
Johngarthia planata (Stimpson, 1860) is an abundant and ecologically important land crab, distributed on East Pacific islands from the Gulf of California to Colombia. However, despite possible dispersal planktotrophic larvae by sea currents, J. not known inshore mainland Central America. In this study, presence Costa Rican reported for first time, strongly supporting significance coastal currents distributional patterns such species. Despite proximity coast larval passing was found in...
Lithraea caustica (litre) es una especie arbórea endémica de Chile que se desarrolla en un clima tipo mediterráneo, caracterizado por presentar estación estival con baja disponibilidad hídrica del suelo, elevada radiación solar y altas temperaturas. Bajo estas condiciones, litre debe desarrollar respuestas ecofisiológicas le permitan sobrellevar períodos restricción hídrica. Con el objetivo conocer dichas respuestas, estableció ensayo controlada bajo condiciones naturales verano. Las plantas...

Abstract Indigenous People and Local Communities (IPLC) can play an important role in reforestation for climate change mitigation while providing environmental livelihood benefits. However, there is a lack of direct comparison between different design's carbon uptake potential their relevance to community reforestation. We evaluate the capture survival four most common designs 14‐year‐long project Emberá eastern Panama. look at native timber mixtures monocultures, agroforestry, natural...
