Understanding the evolutionary history of species in a particular region provides insights into how that fauna was formed. Of interest to biogeographers is examining impact geographical barrier had generating temporal genetic diversity among codistributed species. We examined major New World barrier, Isthmus Tehuantepec (IT) southern Mexico, on regional bird fauna. Specifically, data from 10 montane-forest taxa were analysed using approximate Bayesian computation (ABC) test hypothesis...

It is generally assumed that the Quaternary was a period of heightened diversification in temperate vertebrate organisms. Previous molecular systematics studies have challenged this assertion. We re–examined issue north birds using log–lineage plots and distributions sister–taxon distances. Log–lineage support earlier conclusions avian slowed during Quaternary. To test empirical distances we simulated three sets phylogenies: constant speciation extinction, pulse recent speciation,...

An alternating treatments design was used to investigate the effects of three types opportunities respond (i.e., individual, choral, and mixed responding) on sight words syllable practice in six elementary students with behavioral problems. During responding condition, five out demonstrated a lower rate disruptive behavior, four had fewer intervals off-task behavior. Results participants’ active student were less clear. A discussion limitations, implications, future research directions is included.

This article showcases STEM as an interdisciplinary field in which the disciplines strengthen and support each other (not separate science, technology, engineering, mathematics disciplines). The authors focus on open-ended, complex problem—water quality—as primary teaching learning task. participants, middle school female students (aged 9–15 years), interacted informal educational setting (i.e., Girl Scouts) a research project investigating river quality following river’s restoration....

Youth who are incarcerated in secure detention and commitment settings display a complex array of educational, behavioral, mental health issues that affect the services they require, as well their responsiveness to interventions. Yet, seldom these needs understood or taken into account when providing care settings. In this article, research documenting what is known regarding characteristics youth summarized. Current on use evidence-based interventions for reviewed next. Finally, limitations...

The purpose of this study was to identify statewide trends in school approaches student discipline and examine the associations between punitive practices student, school, local education agency (LEA) characteristics. In addition, we compared disciplinary for schools LEAs that do not allow corporal punishment. Publicly available data from 2010–2011 Florida Department Education Common Core Data were used assess (a) (i.e., suspensions, expulsions, restraints, punishment, changes placement)...

In this article, we follow up on recommendations from the Division for Emotional and Behavioral Health (DEBH) providing school mental health (SMH) services by offering additional implementation suggestions teachers staff. We highlight need urgency of SMH services, particularly during after pandemic, also consider broad issues that interfere with success SMH. then provide a number specific integrating delivery within tiered system supports are intended to empower staff move toward...

Background Multiple loci and population genetic methods were employed to study the phylogeographic history of Patagonian freshwater crab Aegla neuquensis (Aeglidae: Decopoda). This taxon occurs in two large river systems Steppe, from foothills Andes Mountains east Atlantic Ocean. Methodology/Principal Findings A nuclear phylogeny multilocus nested clade analysis detected a fragmentation event between Negro Chico-Chubut systems. occurred approximately 137 thousand years ago. An...

We tested the monophyly and determined phylogenetic relationships of seven genera (Laniisoma, Laniocera, Iodopleura, Pachyramphus, Schiffornis, Tityra, Xenopsaris) 27 31 recognized species subfamily Tityrinae using complete gene sequence data from mitochondrial NADH dehydrogenase subunit 2. Monophyly all was recovered both weighted parsimony Bayesian methods. Intergeneric were nearly identical between two methods are largely in concordance with previous studies. Both analyses basal clades...

To address instructional challenges and poor academic outcomes of youth in juvenile correctional facilities (JCFs), we must understand how why some teachers are effective students responsive to instruction these settings. We observed coded teacher–student interactions from 733 fifteen-minute classroom reading sessions for seven 40 a secure JCF school. then applied series time-window sequential analytic procedures assess connections between approaches teacher behaviors, contingent student...

Abstract We tested the monophyly and determined phylogenetic relationships of seven genera (Laniisoma, Laniocera, Iodopleura, Pachyramphus, Schiffornis, Tityra, Xenopsaris) 27 31 recognized species subfamily Tityrinae using complete gene sequence data from mitochondrial NADH dehydrogenase subunit 2.

Since early in its taxonomic history, placement of the Socorro Wren (Thryomanes sissonii) has been an object contention. Of particular interest is current genus Thryomanes, which makes that ditypic and leads to odd biogeographic scenario for Wren's colonization Island. We assessed phylogenetic position by analyzing 516 base pairs mitochondrial DNA sequences from ND2 gene this species 14 additional wren taxa. Contrary present placement, nested phylogenetically within House complex, being...

Recently acquired tissue makes possible a first molecular assessment of the taxonomic position Soccoro Island endemic mimid Mimodes graysoni . Mitochondrial DNA sequence data from ND‐2 gene was analyzed using parsimony, maximum likelihood and bayesian methods inference. These all placed within strongly supported clade containing four representatives genus Mimus Retention monotypic would make paraphyletic, therefore is more properly in

Understanding how freshwater assemblages have been formed and maintained is a fundamental goal in evolutionary ecological disciplines. Here we use historical approach to test the hypothesis of codivergence three clades Chilean species assemblage. Molecular studies crabs (Aegla: Aeglidae: Anomura) catfish (Trichomycterus arealatus: Trichomycteridae: Teleostei) exhibited similar levels genetic divergences mitochondrial lineages between phylogroups catfish, suggesting shared history among this...
