Refining manual annotation effort of acoustic data to estimate bird species richness and composition: The role of duration, intensity, and time [PDF]

open access: yesEcology and Evolution, 2022
Manually annotating audio files for bird species richness estimation or machine learning validation is a time‐intensive task. A premium is placed on the subselection of files that will maximize the efficiency of unique additional species identified, to ...

Species co-occurrence and management intensity modulate habitat preferences of forest birds [PDF]

open access: yesBMC Biology, 2021
Background Species co-occurrences can have profound effects on the habitat use of species, and therefore habitat structure alone cannot fully explain observed abundances.

Solving Abel’s Type Integral Equation with Mikusinski’s Operator of Fractional Order [PDF]

open access: yesAdvances in Mathematical Physics, 2013
This paper gives a novel explanation of the integral equation of Abel’s type from the point of view of Mikusinski’s operational calculus. The concept of the inverse of Mikusinski’s operator of fractional order is introduced for constructing a ...

Reduced Genetic Diversity and Increased Structure in American Mink on the Swedish Coast following Invasive Species Control. [PDF]

open access: yesPLoS ONE, 2016
Eradication and population reductions are often used to mitigate the negative impacts of non-native invasive species on native biodiversity. However, monitoring the effectiveness of non-native species control programmes is necessary to evaluate the ...

Neocontinuous Mikusiński operators [PDF]

open access: yesTransactions of the American Mathematical Society, 1973
A class of Mikusiiski-type operators in several variables, called ncocontin- uous operators, is studied. These particular operators are closely affiliated with Schwartz distributions on Rk and share certain continuity properties with them. This affiliation is first of all revealed through a common algebraic view of operators and distributions as ...

Construction of Mikusinski operational calculus based on the convolution algebra of distributions. The theorems and the beginning of use

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
We consider the Mikusinski operational calculus based on the convolution algebra of distributions D′+ and D′−. We state and prove the basic theorems, and give examples of Mikusinski operational calculus using, which demonstrate its additional ...

Operational Calculus for the General Fractional Derivatives of Arbitrary Order

open access: yesMathematics, 2022
In this paper, we deal with the general fractional integrals and the general fractional derivatives of arbitrary order with the kernels from a class of functions that have an integrable singularity of power function type at the origin.

Abundance, species richness and diversity of forest bird assemblages – The relative importance of habitat structures and landscape context

open access: yesEcological Indicators, 2021
The variability in the amount and configuration of broad habitat types in the landscape, together with their structural complexity, influence observed biodiversity patterns.

Wavelet transforms in generalized Fock spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
A generalized Fock space is introduced as it was developed by Schmeelk [1-5], also Schmeelk and Takači [6-8]. The wavelet transform is then extended to this generalized Fock space.
