Abstract Understanding how phenotypic traits vary among populations inhabiting different environments is critical for predicting a species’ vulnerability to climate change. Yet, little known about the key functional that determine distribution of and main mechanisms—phenotypic plasticity vs. local adaptation—underlying intraspecific trait variation. Using Asian burying beetle Nicrophorus nepalensis , we demonstrate mountain ranges differing in elevation latitude offer unique thermal which two traits—thermal tolerance reproductive photoperiodism—interact shape breeding phenology. We show on maintain similar tolerances, but differ photoperiodism. Through common garden reciprocal transplant experiments, confirm photoperiodism locally adapted not phenotypically plastic. Accordingly, year-round mountains intermediate are likely be most susceptible future warming because maladaptation occurs when beetles try breed at warmer temperatures.

Abstract Single phenological measures, like the average rate of advancement, may be insufficient to explain how climate change is driving trends in animal populations. Here, we develop a multifactorial concept spring phenology—including onset spring, duration, interannual variability, and their temporal changes—as driver for population dynamics migratory terrestrial species seasonal environments. Using this conceptual model, found that effects advancing phenology on populations buffered or amplified depending duration variability green‐up, those are modified by evolutionary plastic adaptations species. Furthermore, compared our modelling results with empirical data normalized difference vegetation index‐based green‐up 106 European landbird finding similar associations. We conclude changes expected affect bird across Europe identify regions particularly prone suffer declines.

Seasonal migration is a complex and variable behaviour with the potential to promote reproductive isolation. In Eurasian blackcaps ( Sylvia atricapilla ), migratory divide in central Europe separating populations southwest (SW) southeast (SE) autumn routes may facilitate isolation, individuals using new wintering areas Britain show divergence from Mediterranean winterers. We tracked 100 wild characterize these strategies. Blackcaps west east of used predominantly SW SE directions, respectively, but close contact zone many took intermediate (S) routes. At 14.0° E, we documented sharp transition directions across only 27 (10–86) km, implying strong selection gradient divide. northwesterly continental European breeding grounds. They originated surprisingly extensive area, spanning 2000 km range. British winterers bred sympatry SW-bound migrants arrived 9.8 days earlier on grounds, suggesting some for assortative mating by timing.

Abstract Cells and tissues are exposed to multiple mechanical stresses during development, tissue homoeostasis diseases. While we start have an extensive understanding of the influence mechanics on cell differentiation proliferation, how excessive can also lead death may be associated with pathologies has been much less explored so far. Recently, development new perturbative approaches allowing modulation pressure deformation demonstrated that compaction (the reduction size or volume) elimination. Here, discuss relevant type stress parameters could causal from single multicellular systems. We then compare pathways mechanisms proposed survival upon compaction. eventually describe relevance compaction‐induced in vivo , its functions morphogenesis, regulation, cancer progression.

Shifts in the timing of phenological events across many taxa and ecosystems are a result climate change. Within trophic network, mismatches between interlinked species can have negative impacts for biodiversity, ecosystems, network. Here we developed interaction indices that quantify level synchrony asynchrony among groups three levels, as well accounting dynamic representation meteorology. Insect first flight, vegetation green-up arrival migrant birds were indicators, obtained from combination spatially temporally explicit observations citizen science programmes remote sensing platforms ( i.e. , Landsat). To determine shifts created applied several synchrony-asynchrony, combining information critical time windows meteorological variables. demonstrate our method incorporating component new index, implemented relative sliding window analysis, stepwise regression model, to identify preceding on yearly basis.

Modified Aedes aegypti mosquitoes are being mass-reared for release in disease control programs around the world. Releases involving female rely on them able to seek and feed human hosts. To facilitate mass-production of releases, females often provided blood through artificial membrane feeders. When reared across generations there is a risk that will adapt feeding membranes lose their ability test adaptation feeding, we selected replicate populations Ae. either arms or feeders at least 8 generations. Membrane-selected suffered fitness costs, likely due inbreeding depression arising from bottlenecks. had higher rates than human-selected ones, suggesting but they maintained attraction host cues humans despite lack selection these traits. Host-seeking small laboratory cages did not differ between two sources, membrane-selected were compromised semi-field enclosure where host-seeking was tested over longer distance.

In this work, we analyze assemblage composed 13 individuals ontogenetic stages, possibly sex, belonging to giant ground sloth Lestodon armatus (Xenarthra, Folivora), recovered from Playa del Barco site (Pampean Region, Argentina). A dating 19,849 years Cal BP allows assigning a period MIS (Marine Isotope Stage) 2 related end Last Glacial Maximum. Based on multiple lines research (e.g. taphonomy, paleopathology, osteohistology, isotopy), interpret origin diverse paleobiological aspects social behavior, changes, sexual dimorphism, diseases, resource habitat use, trophic relationships) L. armatus. Evidence suggests that was formed by local single event catastrophic mortality, which affected members group. This record represents first accurate evidence gregariousness for sloth, providing new data behavior among extinct Folivora.
