Quantifying the unrecorded loss of avian phylogenetic diversity
Ecography, EarlyView.Humans have drastically reduced avian diversity, with the majority of extinctions occurring on islands. Previous studies have quantified various aspects of this decline, including both taxonomic and phylogenetic diversity loss due to recorded extinctions.

Global convergence analysis of Caputo fractional Whittaker method with real world applications
Cubo (Temuco)The present article deals with the effect of convexity in the study of the well-known Whittaker iterative method, because an iterative method converges to a unique solution \(t^*\) of the nonlinear equation \(\psi(t)=0\) faster when the function's ...

Alpha, beta and gamma diversity in relatively natural, mixed and transformed landscape scenarios
Ecography, EarlyView.Biodiversity losses and biotic homogenisation associated with human‐induced land‐cover changes are key issues for ecology. However, the effects of human‐caused land‐use changes on biodiversity change at the landscape scale are not well understood. Combining the PREDICTS global biodiversity database with MODIS satellite‐based land cover from 2001 to ...

One-dimensional nil-DAHA and Whittaker functions II
Transformation Groups, 2012 This paper is devoted to the theory of nil-DAHA for the root system A1 and its applications to symmetric and non-symmetric (spinor) global q-Whittaker functions. These functions integrate the q-Toda eigenvalue problem and its Dunkl-type non-symmetric version.

Ecography, EarlyView.Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

Remarks on the Whittaker functions
Applied Mathematics Letters, 1992 Whittaker functions are expressed in terms of derivatives of incomplete Gamma functions. Some equalities are then derived with other well-known special functions. Further, some infinite series of the Whittaker functions are expressed in terms of the elementary functions, incomplete Gamma functions, error functions and other special functions.

JCPP Advances, EarlyView.Abstract Background Parent‐led, preschool language interventions may help to mitigate the risk of poor language and literacy outcomes associated with lower socioeconomic status. This study builds on two previous evaluations of a parent‐led early language teaching programme, which demonstrated mixed findings.

Integral transforms of the S-functions
Le Matematiche, 2015 The object of this paper is to introduce a new special function, which will be called S-function. This function is an extension of the generalized Mittag-Leffler function due to Prabhakar [7], generalized Mittag-Leffler function introduced by Srivastava ...

Integral operators involving Whittaker functions [PDF]
Glasgow Mathematical Journal, 1983 We define the integral operators and asandwhereand Wk, u and Mk, u are the Whittaker's confluent hyper-geometric functions. These operators, in their slightly less general form, have been dealt with in [2] and [4]. There the authors have used the fact that these integral operators can be expressed as compositions of the Kober's fractional integral ...

Journal of Quaternary Science, EarlyView.Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...
