Agrilus mali Matsumura (Coleoptera: Buprestidae) density and damage in wild apple Malus sieversii (Rosales: Rosaceae) forests in Central Eurasia under four different management strategies

In 1993 the apple buprestid, Agrilus mali Matsumura (Coleoptera: Buprestidae) native to northeast Asia, invaded the Yili River valley, Xinjiang Uyghur Autonomous Region, China. It is now widespread across 95% of wild apple forests (Malus sieversii (Ledeb.) Roem) in the region. This invasive species poses a major threat to wild apple populations serving as the key germplasm refuge for the ancestor ...

Identification of novel circovirus and anelloviruses from wolverines using a non-invasive faecal sampling approach

Viruses in the families Circoviridae and Anelloviridae have circular single-stranded DNA genomes and have been identified in various animal species. Some members of the Circoviridae family such as beak and feather disease and porcine circovirus have been found to cause disease in their host animals. Anelloviruses on the other hand have not been identified to cause disease in their hosts but are hi...

Collembola communities and soil conditions in forest plantations established in an intensively managed agricultural area

Abstract The challenges of a changing climate have directed greater attention to afforestation, but the effects of afforestation on soil fertility and soil biota have not been fully clarified. To explore changes in the soil conditions in two 20-year-old forest plantations established in formerly intensively fertilized plots of agricultural land, we focused on the current develo...

Freezing temperatures restrict woody plant recruitment and restoration efforts in abandoned montane pastures

Tropical montane forests are being lost at an alarming rate but harbor some of the globe’s most unique biodiversity. The Hawaiian archipelago is a prime example of the importance of high elevation forests to species conservation and persistence as they serve as the last refugia for Hawaiian birds. Yet these forests have been converted to invasive dominated pastures, and efforts to restore them h...

Influence of landscape condition on relative abundance and body condition of two generalist freshwater turtle species

Anthropogenic land use changes have broad impacts on biological diversity, often resulting in shifts in community composition. While many studies have documented negative impacts on occurrence and abundance of species, less attention has been given to native species that potentially benefit from anthropogenic land use changes. For many species reaching high densities in human-dominated landscapes,...

Strategic considerations for invasive species managers in the utilization of environmental DNA (eDNA): Steps for incorporating this powerful surveillance tool

Invasive species surveillance programs can utilize environmental DNA sampling and analysis to provide information on the presence of invasive species. Wider utilization of eDNA techniques for invasive species surveillance may be warranted. This paper covers topics directed towards invasive species managers and eDNA practitioners working at the intersection of eDNA techniques and invasive species s...

Missouri forests 2018: summary report

This summary report provides an overview of findings from the fourth annualized inventory of Missouri forests based on data collected from 2012 to 2018. Forest land area remained stable at 15.4 million acres, and 80 percent of forest land is in the oak/hickory forest-type group. Forests in the State continue to mature with 64 percent in large diameter stands and 61 percent in stands older than 60 ...

Plant Species Composition and Interactions within Communities Invaded by Persicaria perfoliata (Polygonaceae)

Persicaria perfoliata (Mile-a-Minute Weed), an invasive vine, forms monocultural patches of various sizes within infested landscapes among patches also containing other plants. We compared the species composition of P. perfoliata-dominated patches and adjacent nondominated patches in 2 topographically homogeneous sites using 20 paired plots, nonmetric multidimensional scaling, multi-response permu...

Invasive potential of tropical fruit flies in temperate regions under climate change

Tropical fruit flies are considered among the most economically important invasive species detected in temperate areas of the United States and the European Union. Detections often trigger quarantine and eradication programs that are conducted without a holistic understanding of the threat posed....

Origin of the green iguana (Iguana iguana) invasion in the greater Caribbean Region and Fiji

Invasive populations of green iguanas (Iguanidae: Iguana iguana) are widely established beyond their native Central, South American, and Lesser Antillean range in various islands of the Pacific, Florida USA, and in the Greater Caribbean Region. Although widespread, information about these invasions is scarce. Here we determine the origin of invasive populations of green iguanas in Puerto Rico, Fij...

Molecular genetic analysis of air, water, and soil to detect big brown bats in North America

Cave-hibernating bats are widespread in North America but are facing precipitous population declines due to the impacts of white-nose syndrome (WNS). It is in winter hibernacula that bats are most vulnerable to the fungus that causes WNS, but the locations of over-wintering sites in western North America are largely unknown. This poses a significant challenge for bat monitoring, disease surveillan...

Analyzing genetic variation: What can population genomics tell us about the biology and management of our favorite forest pathogens?

The central dogma of molecular biology states that deoxyribonucleic acid (DNA) is transcribed to a form of ribonucleic acid known as messenger RNA (mRNA). These mRNA molecules are then translated to a string of amino acids known as a protein. These processes form the foundation of our understanding of the relationships between genotype (the sequence of nucleotides at a given locus) and phenotype (...
