Harnessing Citizen Science And Collections Data For Invasive Plant Surveillance, Adin L. Ring Jan 2023

Harnessing Citizen Science And Collections Data For Invasive Plant Surveillance, Adin L. Ring

Library Map Prize

Our main source of information about the distribution of invasive plants in the United States comes from occurrence records in three categories: biological collections (physical plant specimens in museums), citizen science (opportunistic observations by untrained civilians), and invasion monitoring (structured observation by government or non-profit agencies). This study compiles a set of 3.1 million occurrence records of 3,578 introduced plant species in the continental United States, and infers spatial, temporal, and taxonomic biases by comparing the three categories of data. We find that citizen science contributes the largest bulk of records, and does better capturing visually conspicuous plants and very …


Sense-Able Hauntings: Ethics And Narratives In Ornithological Specimen Preservation At Yale's Peabody Museum, Elaina Foley Jan 2023

Sense-Able Hauntings: Ethics And Narratives In Ornithological Specimen Preservation At Yale's Peabody Museum, Elaina Foley

Kaplan Senior Essay Prize for Use of Library Special Collections

Until I was standing in between the rows of towering metal specimen cabinets, I didn’t understand how many birds the Yale Peabody Museum holds. Like most people, I had only experienced the display side of museums: its dioramas and glass cases. These displays, while made to embody a certain set of interests, priorities, and values, still serve an obscuring function—they vastly underrepresent the museum’s total collections. In their ornithology collection alone, the Peabody currently holds more than 152,000 bird skins, bones, eggs, nests, and other avian fragments. The Peabody staff members who maintain the ornithology specimen collections are distinct from …


An Assessment Of Geographic And Taxonomic Biases In Research On Climate Change-Related Range Shifts, Evan J. Parker Jan 2022

An Assessment Of Geographic And Taxonomic Biases In Research On Climate Change-Related Range Shifts, Evan J. Parker

Library Map Prize

Geographic and taxonomic biases in ecological literature inhibit the ability of research to be generalized or translated to other systems. This is particularly true with research on climate change-related range shifts, where a diverse and representative set of observations is needed to understand the significant heterogeneity of range shifts and improve models. A literature review was conducted and biases were assessed by examining the geographic location of study areas, the taxonomic makeup of study species, and the location of study areas within species ranges. A substantial geographic skew towards terrestrial, mid-latitude North America and Europe was observed. However, taxonomic coverage …


Climate Niche Evolution In C4+Cam Portulaca And Closely Related C3+Cam Lineages, Nora M. Heaphy Jan 2021

Climate Niche Evolution In C4+Cam Portulaca And Closely Related C3+Cam Lineages, Nora M. Heaphy

Library Map Prize

With at least a hundred independent origins among land plants, the CAM and C4 photosynthetic pathways represent one of the most notable examples of global convergent evolution of a complex trait. While biochemically similar, CAM and C4 are generally understood to be two distinct ecological adaptations evolving along separate trajectories. However, the purslanes (Portulaca), a globally widespread clade of around 100 species of annual and perennial succulents, are able to operate both CAM and C4 cycles in the same leaf. Portulaca likely originated from a facultative CAM ancestor and then evolved a C4 system at least three times …


Ranging And Behavior Of Black And Gold Howler Monkeys In Formosa, Argentina, Claire Rossi De Leon Jan 2019

Ranging And Behavior Of Black And Gold Howler Monkeys In Formosa, Argentina, Claire Rossi De Leon

Library Map Prize

Howler monkeys (Alouatta spp.) are known for their adaptability, allowing them to inhabit a large range of forest types and driving high levels of variation in ranging and behavioral patterns. I address a series of hypotheses relating these relationships: 1) If an energy minimizing lifestyle is an adaptation to eating high quantities of leaves, then howler groups that have a high proportion of leaves in their diet will occupy smaller home ranges, have shorter daily path lengths, and spend more time resting, 2) if temperature is the primary driver of high levels of resting, then howlers will conserve energy and …


Species Distribution Modeling Of North American Odonates, Rebecca Beilinson Jan 2016

Species Distribution Modeling Of North American Odonates, Rebecca Beilinson

Library Map Prize

Species distribution modeling, which uses species-environment relationships to predict species’ geographic ranges, is a powerful technique for biogeographical and ecological analysis as well as for conservation planning. However, it has typically been underutilized for invertebrates and for freshwater species, as modeling these groups can pose unique challenges. Here I present methods for modeling odonate distributions and demonstrate these methods for four North American species. I show that incorporating expert-derived range maps as spatial priors can significantly improve model performance as compared to MaxEnt models. I also introduce a new distance to freshwater layer as an environmental variable, and show that …

Resource Use In The Trinational Sangha River Region Of Equatorial Africa: Histories, Knowledge Forms, And Institutions, Heather E. Eves, Rebecca Hardin, Stephanie Rupp Jan 1998

Resource Use In The Trinational Sangha River Region Of Equatorial Africa: Histories, Knowledge Forms, And Institutions, Heather E. Eves, Rebecca Hardin, Stephanie Rupp

Yale School of the Environment Bulletin Series

This volume is based on an international conference, “Natural Resource Use Relations in the Trinational Sangha River Region of the Northwest Congo Basin,” held at Yale University in September 1997. In recognition of the bilingual context in which conservation occurs in the three countries of the Sangha region — Cameroon, Central African Republic, and Congo — all sessions of the conference were conducted simultaneously in French and English. This publication, which is a complete rendering of the conference papers and discussion sessions, is available in its entirety in both French and English.
