The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

The critical density for the frog model is the degree of the tree
, 2016 The frog model on the rooted d-ary tree changes from transient to recurrent as the number of frogs per site is increased. We prove that the location of this transition is on the same order as the degree of the tree.Comment: 12 pages; final published ...

Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Threatened amphibians of the site of ecological use "Dąbski Pond" [PDF]
, 2012 W latach 2009-2010 przeprowadzono inwentaryzację płazów krakowskiego użytku ekologicznego „Staw Dąbski”. Jej celem było określenie składu i liczebności żyjących tam gatunków, porównanie aktualnych danych z wcześniejszymi oraz ustalenie zagrożeń.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, EarlyView.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Routing Games over Time with FIFO policy
, 2017 We study atomic routing games where every agent travels both along its decided edges and through time. The agents arriving on an edge are first lined up in a \emph{first-in-first-out} queue and may wait: an edge is associated with a capacity, which ...

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Acoustic Phenotypes of an Alpine European Common Frog Population
International Journal of Zoology and Animal Biology, 2019 In this work we studied the acoustic variability in the induced release call on wild populations of the European common frog Rana temporaria. We used a computational model to analyze the induced release calls in both sexes. Our analysis detected three different acoustic phenotypes: (a) Non-canonical males comprised a large part of the population and ...
