occumb: An R package for site occupancy modeling of eDNA metabarcoding data

Population Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

Irreducible restrictions of closed mappings

Topology and its Applications, 1998
By a result of \textit{N. Lashnev} [Sov. Math., Dokl. 6, 1504-1506 (1966); translation from Dokl. Akad. Nauk SSSR 165, 756-758 (1965; Zbl 0145.19603)], every continuous, closed surjection \(f:X\to Y\), with \(X\) paracompact and \(Y\) Fréchet, is inductively irreducible (i.e., there exists a closed \(X'\subset X\) such that \(f(X')=Y\) and \(f| X'\) is

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

BiLipschitz Decomposition of Lipschitz Maps between Carnot Groups

Analysis and Geometry in Metric Spaces, 2015
Let f : G → H be a Lipschitz map between two Carnot groups. We show that if B is a ball of G, then there exists a subset Z ⊂ B, whose image in H under f has small Hausdorff content, such that B\Z can be decomposed into a controlled number of pieces, the ...

A 2nd generation linkage map of Heterobasidion annosum s.l. based on in silico anchoring of AFLP markers. [PDF]

PLoS ONE, 2012
In this study, we present a 2(nd) generation genetic linkage map of a cross between the North American species Heterobasidion irregulare and H. occidentale, based on the alignment of the previously published 1(st) generation map to the parental genomes ...

Construction of a 750-kb bacterial clone contig and restriction map in the region of human chromosome 21 containing the progressive myoclonus epilepsy gene.

Genome Research, 1996
The gene responsible for progressive myoclonus epilepsy of the Unverricht-Lundborg type (EPM1) is located on human chromosome 21q22.3 in a region defined by recombination breakpoints and linkage disequilibrium. As part of an effort to clone the EPM1 gene

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

Population Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

AGORA: Assembly Guided by Optical Restriction Alignment

BMC Bioinformatics, 2012
Background Genome assembly is difficult due to repeated sequences within the genome, which create ambiguities and cause the final assembly to be broken up into many separate sequences (contigs).

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...
