Previous reproductive success and environmental variation influence nest‐site fidelity of a subarctic‐nesting goose

Ecology and Evolution
Nest‐site fidelity is a common strategy in birds and is believed to be adaptive due to familiarity with local conditions. Returning to previously successful nest sites (i.e., the win‐stay lose‐switch strategy) may be beneficial when habitat quality is ...

Long distance biotic dispersal of tropical seagrass seeds by marine mega-herbivores

Scientific Reports, 2017
Terrestrial plants use an array of animals as vectors for dispersal, however little is known of biotic dispersal of marine angiosperms such as seagrasses.

Female dispersal and isolation-by-distance of Nasonia vitripennis populations in a local mate competition context [PDF]

, 2009
Dispersal behavior directly influences the level of inbreeding, but the effect of inbreeding avoidance on dispersal is less well studied. The parasitoid wasp Nasonia vitripennis (Walker) (Hymenoptera: Chalcidoidea: Pteromalidae) is known to mate ...

Assessing Altered Coating Adhesion on Plasma‐Deoxidized Surfaces Under Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
This study demonstrates the effectiveness of atmospheric pressure plasma pretreatment in modifying silicon and stainless steel surfaces to improve adhesion. Argon‐hydrogen plasma increases surface roughness and improves adhesion strength, whereas pure argon results in smoother surfaces and structural changes.

Phylogeography of the Rhabditis (Pellioditis) marina species complex: evidence for cosmopolitanism, restricted gene flow, recent range expansions and accelerated evolution [PDF]

, 2007
The nematode Rhabditis (Pellioditis) marina has a worldwide distribution despite presumably low dispersal abilities. Recent studies on a local scale have illustrated that R.

Productivity‐Driven Optimization of Laser Powder Bed Fusion Parameters for IN718 Superalloy: Process Control, Microstructure, and Mechanical Properties

Advanced Engineering Materials, EarlyView.
This study demonstrates how optimizing laser power, scanning speed, and hatching distance in laser powder bed fusion can boost the productivity of Inconel 718 manufacturing by up to 29% while maintaining mechanical integrity. The work delivers a validated process window and cost–time analysis, offering industry‐ready guidelines for efficient additive ...

Modelling forest recolonization by an epiphytic lichen using a landscape genetic approach [PDF]

, 2018
The process of recolonization after disturbance is crucial for the persistence and dynamics of patch-tracking metapopulations. We developed a model to compare the spatial distribution and spatial genetic structure of the epiphytic lichen Lobaria ...

Long‐Distance, Transfrontier Carnivore Dispersals in Southern Africa

Ecology and Evolution
ABSTRACTInformation on long‐range dispersal in tropical carnivores is limited compared to their temperate counterparts. Here we present data on long‐range, transboundary dispersals for three species of tropical carnivores: African wild dog (Lycaon pictus), African lion (Panthera leo), and spotted hyena (Crocuta crocuta).

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Evolution of dispersal and life history strategies – Tetrahymena ciliates

BMC Evolutionary Biology, 2007
Background Considerable attention has focused on how selection on dispersal and other core life-history strategies (reproductive effort, survival ability, colonization capacity) may lead to so-called dispersal syndromes.
