It Turned Into A Bioblitz: Urban Data Collection For Building Scientific Literacy And Environmental Connection, Kelly O'Donnell, Lisa Brundage

Publications and Research

In 2013, Macaulay Honors College redesigned its required science curriculum to focus on scientific literacy skills rather than content. Central to this shift was inclusion of a data collection event, a BioBlitz, to provide students with the basis for their own semester-long research projects. Students are teamed with naturalists in an urban green space to find as many species as they can in 24 h and to contribute to a global biodiversity database via the app iNaturalist. We have learned two important lessons: (1) developing an interdisciplinary curriculum with a high degree of experiential learning is more successful when both …

Forest Cover And Geographic Distance Influence Fine-Scale Genetic Structure Of Leaf-Toed Geckos In The Tropical Dry Forests Of Western Mexico, Connor M. French, Casey-Tyler Berezin, Isaac Overcast, Fausto R. Méndez De La Cruz, Saptarsi Basu, Roberto Lhemish Martínez Bernal, Robert W. Murphy, Michael J. Hickerson, Christopher Blair

Publications and Research

The biodiversity within tropical dry forests (TDFs) is astounding and yet poorly catalogued due to inadequate sampling and the presence of cryptic species. In the Mexican TDF, endemic species are common, and the landscape has been continually altered by geological and anthropogenic changes. To understand how landscape and environmental variables have shaped the population structure of endemic species, we studied the recently described species of leaf-toed gecko, Phyllodactylus benedettii, in coastal western Mexico. Using double-digest restriction site-associated DNA sequencing data, we first explore population structure and estimate the number of ancestral populations. The results indicate a high degree of …

Phylogenomics Of Alligator Lizards Elucidate Diversification Patterns Across The Mexican Transition Zone And Support The Recognition Of A New Genus, Christopher Blair, Robert W. Bryson Jr, Uri O. García-Vázquez, Adrián Nieto-Montes De Oca, David Lazcano, John E. Mccormack, John Klicka

Publications and Research

Genomic data continue to advance our understanding of species limits and biogeographic patterns. However, there is still no consensus regarding appropriate methods of phylogenomic analysis that make the best use of these heterogeneous data sets. In this study, we used thousands of ultraconserved element (UCE) loci from alligator lizards in the genus Gerrhonotus to compare and contrast species trees inferred using multiple contemporary methods and provide a time frame for biological diversification across the Mexican Transition Zone (MTZ). Concatenated maximum likelihood (ML) and Bayesian analyses provided highly congruent results, with differences limited to poorly supported nodes. Similar topologies were inferred …

The Paradox Of Retained Genetic Diversity Of Hippocampus Guttulatus In The Face Of Demographic Decline, Rupert Stacy, Jorge Palma, Miguel Correia, Anthony B. Wilson, José Pedro Andrade, Rita Castilho

Publications and Research

Genetic diversity is the raw foundation for evolutionary potential. When genetic diversity is significantly reduced, the risk of extinction is heightened considerably. The long-snouted seahorse (Hippocampus guttulatus) is one of two seahorse species occurring in the North-East Atlantic. The population living in the Ria Formosa (South Portugal) declined dramatically between 2001 and 2008, prompting fears of greatly reduced genetic diversity and reduced effective population size, hallmarks of a genetic bottleneck. This study tests these hypotheses using samples from eight microsatellite loci taken from 2001 and 2013, on either side of the 2008 decline. The data suggest that the population has …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

The Insular Herpetofauna Of Mexico: Composition, Conservation, And Biogeographic Patterns, Juan Valentín Pliego‐Sánchez, Christopher Blair, Aníbal H. Díaz De La Vega‐Pérez, Víctor H. Jiménez‐Arcos

Publications and Research

We compile a Mexican insular herpetofaunal checklist to estimate endemism, conservation status, island threats, net taxonomic turnover among six biogeographic provinces belonging to the Nearctic and Neotropical regions, and the relationships between island area and mainland distance versus species richness. We compile a checklist of insular herpetofaunal through performing a literature and collection review. We define the conservation status according to conservation Mexican law, the Red List of International Union for Conservation of Nature, and Environmental Vulnerability Scores. We determine threat percentages on islands according to the 11 major classes of threats to biodiversity. We estimate the net taxonomic turnover …

Not Withering On The Evolutionary Vine: Systematic Revision Of The Brown Vine Snake (Reptilia: Squamata: Oxybelis) From Its Northern Distribution, Robert C. Jadin, Christopher Blair, Sarah A. Orlofske, Michael J. Jowers, Gilson A. Rivas, Laurie J. Vitt, Julie M. Ray, Eric N. Smith, John C. Murphy

Publications and Research

The genus Oxybelis currently is composed of four taxa despite numerous studies suggesting and describing multiple taxa within the O. aeneus complex. Here, we utilize a multilocus molecular dataset (i.e. cyt b, ND4, 12S, 16S, cmos, PRLR, 3663 bp) to conduct phylogenetic analyses to assess the evolutionary history of Oxybelis. Our molecular analyses find three major lineages of Oxybelis (i.e. O. aeneus complex, O. brevirostris, O. fulgidus complex) with a sister relationship between O. brevirostris and the O. aeneus complex to the exclusion of the O. fulgidus complex. More specifically, O. aeneus appears to harbor at least …

16s Rrna Amplicon Sequencing Of Urban Prokaryotic Communities In The South Bronx River Estuary, Eugenia Naro-Maciel, Melissa R. Ingala, Irena E. Werner, Allison M. Fitzgerald

Publications and Research

Biodiversity monitoring is an essential component of restoration efforts. We sequenced 16S rRNA gene amplicons from sediments and waters of Hunts Point Riverside Park and Soundview Park, located in a historically degraded but recovering urban estuary in New York. In total, 16,165 unique amplicon sequence variants were recovered, and Proteobacteria was the dominant phylum.

Standards For Distribution Models In Biodiversity Assessments, Miguel B. Araújo, Robert P. Anderson, A. Márcia Barbosa, Colin M. Beale, Carsten F. Dormann, Regan Early, Raquel A. Garcia, Antoine Guisan, Luigi Maiorano, Babak Naimi, Robert B. O'Hara, Niklaus E. Zimmermann, Carsten Rahbek

Publications and Research

Demand for models in biodiversity assessments is rising, but which models are adequate for the task? We propose a set of best-practice standards and detailed guidelines enabling scoring of studies based on species distribution models for use in biodiversity assessments. We reviewed and scored 400 modeling studies over the past 20 years using the proposed standards and guidelines. We detected low model adequacy overall, but with a marked tendency of improvement over time in model building and, to a lesser degree, in biological data and model evaluation. We argue that implementation of agreed-upon standards for models in biodiversity assessments would …

Cryptic Diversity In The Mexican Highlands: Thousands Of Uce Loci Help Illuminate Phylogenetic Relationships, Species Limits And Divergence Times Of Montane Rattlesnakes (Viperidae: Crotalus ), Christopher Blair, Robert W. Bryson Jr, Charles W. Linkem, David Lazcano, John Klicka, John E. Mccormack

Publications and Research

With the continued adoption of genome‐scale data in evolutionary biology comes the challenge of adequately harnessing the information to make accurate phylogenetic inferences. Coalescent‐based methods of species tree inference have become common, and concatenation has been shown in simulation to perform well, particularly when levels of incomplete lineage sorting are low. However, simulation conditions are often overly simplistic, leaving empiricists with uncertainty regarding analytical tools. We use a large ultraconserved element data set (>3,000 loci) from rattlesnakes of the Crotalus triseriatus group to delimit lineages and estimate species trees using concatenation and several coalescent‐based methods. Unpartitioned and partitioned maximum …

Facebook As A Social Outreach And Advocacy Tool In Intersex/Dsd Groups, Emelie J. Ali Ms

Publications and Research

My project includes a netnography of a Facebook intersex group called Families and Friends of Intersex People. I observed the group’s forms of communication within the group and which topics they discussed. It appears one of the major concerns the group has is the use of nonconsensual, sex assignment surgery on infants to “correct” their body to match a gender identity. I have also discovered a link between being intersex and affiliated with the LGBT+ community. Since the 20th century, intersex people have been stigmatized due to their assumed ability to engage in sexual, same-sex relations. I have concluded that …

Biodiversity Of Medicinal Plants In The Highlands: Problems And Perspectives, Vyacheslav Dushenkov

Publications and Research

Climate change is affecting medicinal plants around the world and could ultimately lead to losses of some key species, in particular species endemic to a region and causing plants to migrate to new ranges. As the situation unfolds, climate change may become a pressing issue for the herbal community, affecting medicinal plant supply chains with varying requirements for plant cultivation, resource management in the wild, harvesting, processing, and importantly marketing.

Review: Living In Obscurity: Danté Fenolio – Life In The Dark., Aldemaro Romero Jr.

Publications and Research

The reduction and/or disappearance of phenotypic features is a biological phenomenon that has intrigued humans ever since prehistoric times. The earliest known anthropological representation of a creature showing the loss of phenotypic features dates back to ca. 22,000 YBP (Upper Paleolithic). It is a carved drawing of a wingless cave cricket, Troglophilus sp., on a bison (Bison bonasus) bone found in the Grotte des Trois Frères (Three Brothers Cave) in the central Pyrénées, France. Since then, we have witnessed how the study of organisms living in lightless environments went through a number of scientific historical periods. First was the age …

Diversity-Dependent Cladogenesis Throughout Western Mexico: Evolutionary Biogeography Of Rattlesnakes (Viperidae: Crotalinae: Crotalus And Sistrurus), Christopher Blair, Santiago Sánchez-Ramírez

Publications and Research

Rattlesnakes (Crotalus and Sistrurus) represent a radiation of approximately 42 species distributed throughout the New World from southern Canada to Argentina. Interest in this enigmatic group of snakes continues to accrue due, in part, to their ecomorphological diversity, contributions to global envenomations, and potential medicinal importance. Although the group has garnered substantial attention from systematists and evolutionary biologists for decades, little is still known regarding patterns of lineage diversification. In addition, few studies have statistically quantified broad-scale biogeographic patterns in rattlesnakes to ascertain how dispersal occurred throughout the New World, particularly among the different major biomes of the …

Historical And Contemporary Demography Of Leaf-Toed Geckos (Phyllodactylidae: Phyllodactylus) In The Mexican Dry Forest, Christopher Blair, Victor H. Jiménez Arcos, Fausto R. Méndez De La Cruz, Robert W. Murphy

Publications and Research

Disentangling the relative influence of historical versus contemporary processes shaping the spatial distribution of genetic variation is critical if we are to effectively mitigate key biodiversity issues. We utilize a comprehensive approach based on different molecular marker types and analytical methods to understand the demographic consequences of recent habitat fragmentation in a spatially explicit context. We focus our efforts on native leaf-toed geckos (Phyllodactylus tuberculosus saxatilis) throughout fragmented habitat in the tropical dry forest of northern Mexico as recent evidence suggests that geographic ranges for these geckos may be much smaller than currently realized. However, no data are …

Revisiting The Vanishing Refuge Model Of Diversification, Robert Damasceno, Maria L. Strangas, Ana C. Carnaval, Miguel T. Rodrigues, Craig Moritz

Publications and Research

Much of the debate around speciation and historical biogeography has focused on the role of stabilizing selection on the physiological (abiotic) niche, emphasizing how isolation and vicariance, when associated with niche conservatism, may drive tropical speciation. Yet, recent re-emphasis on the ecological dimensions of speciation points to a more prominent role of divergent selection in driving genetic, phenotypic, and niche divergence. The vanishing refuge model (VRM), first described by Vanzolini and Williams (1981), describes a process of diversification through climate-driven habitat fragmentation and exposure to new environments, integrating both vicariance and divergent selection. This model suggests that dynamic climates and …

Project Safe Flight: Making New York Safe For Migratory Birds, Kaitlyn L. Parkins, Susan B. Elbin Ph.D., Adriana Palmer, Darren Klein, Elle Barnes

Publications and Research

More than 100 species of migratory birds pass through New York City during spring and fall migrations. Located at the nexus of several migratory routes, New York City’s tall buildings and reflective glass pose a serious threat to over 100 species of migratory birds. Since 1997, NYC Audubon has led Project Safe Flight (PSF), a volunteer-based citizen-science project, with the goal of monitoring and mitigating bird collisions. We examined 16 years of PSF data, during which volunteers collected over 6,000 birds of 126 different species. The top two species, White-throated Sparrow and Common Yellowthroat, make up 23% of all collisions. …

Landscape Genetics Of Leaf-Toed Geckos In The Tropical Dry Forest Of Northern Mexico, Christopher Blair, Victor H. Jimenez-Arcos, Fausto R. Mendez De La Cruz, Robert W. Murphy

Publications and Research

Habitat fragmentation due to both natural and anthropogenic forces continues to threaten the evolution and maintenance of biological diversity. This is of particular concern in tropical regions that are experiencing elevated rates of habitat loss. Although less well-studied than tropical rain forests, tropical dry forests (TDF) contain an enormous diversity of species and continue to be threatened by anthropogenic activities including grazing and agriculture. However, little is known about the processes that shape genetic connectivity in species inhabiting TDF ecosystems. We adopt a landscape genetic approach to understanding functional connectivity for leaf-toed geckos (Phyllodactylus tuberculosus) at multiple sites …

Ecology Of The Malay Civet (Viverra Tangalunga) In A Logged And An Unlogged Forest In Sabah, East Malaysia, Christina P. Colon

Publications and Research

Malay civets in a dipterocarp rain forest were studied from December, 1995, through June, 1997, in the Ulu Segama Forest Reserve in Sabah, East Malaysia. To investigate the basic ecology of this species and explore the potential impact of selective logging, data on home range, activity and diet were collected on study animals in an unlogged and a selectively logged forest, and comparisons made.

Density in the unlogged forest was 1/0.46 km² , and 1/1.07 km² in the logged forest. Mean home range size based on a 95% minimum convex polygon was 110 ha. and did not differ …

The Use Of Plot Surveys For The Study Of Ethnobotanical Knowledge: A Brunei Dusun Example, Jay H. Bernstein, Roy Ellen, Bantong Bin Antaran

Publications and Research

This paper describes a technique for using plot surveys to measure individual informants' ethnobotanical knowledge of forests, as applied to the Dusun community of Merimbun in Brunei. Two knowledgeable but non-literate Dusun informants enumerated marked plots of both recent and old secondary growth mixed dipterocarp forest near the village. They were able to provide names (other than life-forms or the most general basic and intermediate categories) for 86-97% of species growing in the plots. Between 152 and 170 plant names were elicited by the surveys. In all cases, about 88% of the names were at the basic naming level and …
