Phylogenetic relationships in Betula (Betulaceae) based on AFLP markers [PDF]

, 2008
The genus Betula comprises various species in boreal and temperate climate zones of the Northern Hemisphere. The taxonomy of Betula is controversial and complicated by parallel evolution of morphological traits, polyploidization events, and extensive ...

Sociodemographic, microbial and phylogentic studies of Mycobacterium tuberculosis cases diagnosed in El-Minia governorate, Egypt

African Journal of Microbiology Research, 2016
Egypt is considered one of the high-burden countries in WHO’s Eastern Mediterranean region. This study determined the sociodemographic, microbial and phylogentic characteristics for Mycobacterium tuberculosis cases diagnosed in El-Minia governorate in upper Egypt. Fifty clinical samples were collected (male-to-female sex ratio 1.5 and 50% within the 21-

Reassessment of the enigmatic “Prestosuchus” loricatus (Archosauria: Pseudosuchia) from the Middle‐Late Triassic of southern Brazil

The Anatomical Record, Volume 307, Issue 4, Page 974-1000, April 2024.
Abstract Our knowledge of the diversity and evolution of South American Triassic pseudosuchians has greatly improved in the past 15 years, due to new discoveries, but also to the revision of several historically important specimens. One of the earliest descriptions of pseudosuchians from the Triassic of Brazil stems from the classic work of Huene from ...

Mitochondrial genome evaluation and implications for phylogenetic relationships of Haemadipsa hainana song, Zhang and Tan 1977 (Arhynchobdellida: Haemadipsidae)

Mitochondrial DNA. Part B. Resources
Haemadipsa hainana Song, Zhang and Tan 1977, a blood-feeding terrestrial leech, serves as an ecological indicator of habitat quality and potential mammal abundance. Currently, the molecular phylogenetic status of this species remains unclear.

Meningococcal Carriage among College Freshmen in Kashmir, North India- A Single Centre Study [PDF]

Journal of Clinical and Diagnostic Research, 2017
Introduction: Data on the community carriage of meningococci in developing countries are sparse. Knowledge about the same would help identify demographic and socio-behavioural risk factors, the need for infection control strategies and the composition of

Metacommunity phylogenteic structure along environmental gradients

, 2017
Phylogenetic information has increasingly been included in studies of local communities and also at broad spatial scales. Despite recent criticisms in the last four years, phylogenetic relationships may still provide insights into theorganization and assembly of ecological communities.

Layer‐specific imprints of traits within a plant–herbivore–predator network – complementary insights from complementary methods

Ecography, Volume 2024, Issue 4, April 2024.
Who interacts with whom is a key question in community and network ecology. The concept that these interactions may be driven by a match between the traits of consumer and resource species is known as trait‐matching. If trait‐matching would allow for general predictions of interaction structure based on sufficiently few and easily‐measurable traits ...

A Note on Encodings of Phylogenetic Networks of Bounded Level [PDF]

, 2009
Driven by the need for better models that allow one to shed light into the question how life's diversity has evolved, phylogenetic networks have now joined phylogenetic trees in the center of phylogenetics research. Like phylogenetic trees, such networks

Topology reconstruction using time series data in telecommunication networks

Networks, Volume 83, Issue 2, Page 408-427, March 2024.
Abstract We consider Hybrid fiber‐coaxial (HFC) networks in which data is transmitted from a root node to a set of customers using a series of splitters and coaxial cable lines that make up a tree. The physical locations of the components in a HFC network are always known but frequently the cabling is not.

Molecular identification of heat shock protein 70 (Hsp70) gene in the Indian edible oyster Crassostrea madrasensis (Preston) and Indian brown mussel Perna indica Kuriakose & Nair, 1976 [PDF]

, 2012
Bivalves are constantly exposed to different kinds of stressors as they live in a habitat with frequent changes in environmental parameters. The xenobiotic pollutants also contribute to the stressful routine of bivalves.
