Abundance Of Songbirds In Eastern Hemlock Stands Following Chemical Treatment For Hemlock Woolly Adelgid [PDF]

open access: yes, 2020
In the 1960’s the invasive Hemlock Woolly Adelgid (Adelges tsugae [hereafter, HWA]) began to spread west across the hemlock stands of the Eastern U.S. killing a significant number of Eastern Hemlock (Tsuga canadensis).

Using life history traits to assess climate change vulnerability in understudied species 利用生活史特征评估研究不足物种的气候变化脆弱性

open access: yesIntegrative Conservation, Volume 3, Issue 4, Page 368-381, December 2024.
Lack of species information complicates understanding climate change vulnerability, but life history traits can be proxies for missing information. In the north‐central United States, useful traits for discriminating vulnerability of amphibians include range size, clutch size, diel activity patterns, and habitat breadth.

Insights into phylogenetic positions and distribution patterns: Complete mitogenomes of two sympatric Asian horned toads in Boulenophrys (Anura: Megophryidae)

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
The mitogenomes of two endemic and threatened Asian horned toads, Boulenophrys sangzhiensis and Boulenophrys tuberogranulata, were sequenced and reported for the first time. A phylogenetic reconstruction based on all available mitogenomes within Megophryidae revealed a very special phylogenetic and distributional pattern of the two sympatric species ...

Age, forest structure, and disturbance history of five potential old-growth forests in eastern Kentucky\u27s Cumberland Plateau [PDF]

open access: yes, 2011
The Cumberland Plateau (CP) is an ecoregion of global importance, yet its extent of old- growth forest (OG) is not well known. Due to its rarity and importance, understanding what OG remains is needed to deduce the region\u27s health.

Biotic interactions vary across species' ranges and are likely conserved through geological time

open access: yesJournal of Biogeography, Volume 51, Issue 5, Page 894-908, May 2024.
Abstract Aim The evolutionary interactions between western spadefoot toads (genus Spea) represent a textbook example of character displacement, facilitated by dietary specialization of one Spea species on fairy shrimp (Anostraca) when all three co‐occur. The aim of this study is to understand the covariation between predator (Spea) and prey (Anostraca)

Vocal responses of adult Eastern Bluebirds (Sialia sialis) to potential nest predators and the behavioral responses of nestlings [PDF]

open access: yes, 2014
The alarm calls of some birds are functionally referential and may provide nestlings with information about the threat posed by potential predators. However, few investigators have examined the responses of nestlings in cavity nests to the anti-predator ...

Piecing the barcoding puzzle of Palearctic water frogs (Pelophylax) sheds light on amphibian biogeography and global invasions

open access: yesGlobal Change Biology, Volume 30, Issue 3, March 2024.
By revisiting three decades of molecular data, we retraced the evolution and mapped the diversity of Pelophylax water frogs, a famous group of Eurasian amphibians. The results highlight the Paratethys Paleo‐sea as a major driver of diversification, implement a new timetree validation approach, emphasize the rare ability of lineages to hybridize despite

Blood meal metabarcoding of the argasid tick (Ornithodoros turicata Dugès) reveals extensive vector‐host associations

open access: yesEnvironmental DNA, Volume 6, Issue 1, January–February 2024.
This study has examined vertebrate blood meals in Ornithodoros turicata soft ticks (Acari: Argasidae) from two locations in Texas, USA. Vertebrates from 274 individual O. turicata revealed 27 different vertebrate hosts and were compared to camera trap observations in both locations showing over‐ or under‐utilization of different hosts. O.
