An index for measuring functional extension and evenness in trait space
Ecology and Evolution, 2021 Most existing functional diversity indices focus on a single facet of functional diversity. Although these indices are useful for quantifying specific aspects of functional diversity, they often present some conceptual or practical limitations in ...

Diversity and Selection of Surface Marine Microbiomes in the Atlantic-Influenced Arctic
Frontiers in Microbiology, 2022 Arctic marine environments are experiencing rapid changes due to the polar amplification of global warming. These changes impact the habitat of the cold-adapted microbial communities, which underpin biogeochemical cycles and marine food webs.

Gauging of Lorentz Group WZW Model by its Null Subgroup [PDF]
, 1996 We consider the standard vector gauging of Lorentz group $ SO(3,1) $ WZW model by its non-semisimple null Euclidean subgroup in two dimensions $ E(2) $.

Bird species diversity in the Atlantic Forest of Brazil is not explained by the Mid-domain Effect
Zoologia (Curitiba), 2012 The Atlantic Forest is an excellent case study for the elevational diversity of birds, and some inventories along elevational gradients have been carried out in Brazil.

Ecology and Evolution, 2020 Identifying seasonal shifts in community assembly for multiple biological groups is important to help enhance our understanding of their ecological dynamics. However, such knowledge on lotic assemblages is still limited. In this study, we used biological

Detecting Unspecified Structure in Low-Count Images
, 2015 Unexpected structure in images of astronomical sources often presents itself upon visual inspection of the image, but such apparent structure may either correspond to true features in the source or be due to noise in the data.

Universally measurable sets in generic extensions [PDF]
, 2009 A subset of a topological space is said to be \emph{universally measurable} if it is measured by the completion of each countably additive $\sigma$-finite Borel measure on the space, and \emph{universally null} if it has measure zero for each such ...

Null tests of the standard model using the linear model formalism
, 2018 We test both the FLRW geometry and $\Lambda$CDM cosmology in a model independent way by reconstructing the Hubble function $H(z)$, the comoving distance $D(z)$ and the growth of structure $f\sigma_8(z)$ using the most recent data available.

Hamiltonian flows on null curves
, 2010 The local motion of a null curve in Minkowski 3-space induces an evolution equation for its Lorentz invariant curvature. Special motions are constructed whose induced evolution equations are the members of the KdV hierarchy.

The architecture of antagonistic networks: Node degree distribution, compartmentalization and nestedness [PDF]
Computational Ecology and Software, 2015 Describing complex ecosystems as networks of interacting components has proved fruitful - revealing many distinctive patterns and dynamics of ecological systems.
