Article Abstract
Two-phase plant communities with an engineer conforming conspicuous patches and affecting the performance and patterns of coexisting species are the norm under stressful conditions. To unveil the mechanisms governing coexistence in these communities at multiple spatial scales, we have developed a new point-raster approach of spatial pattern analysis, which was applied to a Mediterranean high mountain grassland to show how Festuca curvifolia patches affect the local distribution of coexisting species. We recorded 22 111 individuals of 17 plant perennial species. Most coexisting species were negatively associated with F. curvifolia clumps. Nevertheless, bivariate nearest-neighbor analyses revealed that the majority of coexisting species were confined at relatively short distances from F. curvifolia borders (between 0-2 cm and up to 8 cm in some cases). Our study suggests the existence of a fine-scale effect of F. curvifolia for most species promoting coexistence through a mechanism we call 'facilitation in the halo'. Most coexisting species are displaced to an interphase area between patches, where two opposite forces reach equilibrium: attenuated severe conditions by proximity to the F. curvifolia canopy (nutrient-rich islands) and competitive exclusion mitigated by avoiding direct contact with F. curvifolia.

Endogenous viral elements in termite genomes reveal extensive diversity of deltaviruses and provide insights into their origins.

Deltaviruses are subviral agents of animals, which, in humans, require a hepadnavirus helper for transmission. The absence of deltavirus-like endogenous viral elements (δEVEs) has prevented an understanding of their evolution in deep time. By screening the representative genomes of all metazoans for endogenous delta antigen-like sequences, we report the discovery of 13 δEVEs in the genomes of five species of termites.

Color polymorphism can influence the evolutionary fate of cryptic species because it increases populations' chances of survival in heterogenous or variable environments. Yet, little is known about the molecular and evolutionary mechanisms underlying the persistence of cryptic color polymorphisms, or the impact these polymorphisms have on the macroevolutionary dynamics of lineages. Here, we examine the evolutionary history of the most widespread cryptic color polymorphism in anurans, involving green and brown morphs.

As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute. Another consideration is whether the relative importance of different tenures varies depending on the specific goals of the PA network. We used the mammal fauna of the Australian monsoon tropics (AMT), one of the world's largest intact tropical savannas, as a case study to address these questions.

Tree cavities are critical habitats for numerous vertebrate species, serving as keystone resources for nesting, roosting, and shelter. We document the first evidence of an individual güiña () breeding within a tree cavity of a standing dead tree. We explore its implications on breeding productivity and complementing this record with evidence from camera trap surveys conducted in temperate forests of south-central Chile.

Body temperature is important for the behavioural and ecological performance of winged insects whose body temperature must exceed ambient temperature to fly. Although thermoregulation may affect geographical distribution and habitat selection of closely related species. The few studies that have been done on this subject have shown mixed results.
