Abstract:
... Altered precipitation in the arid southwestern USA will influence both plant and soil communities, but relatively few studies explore its impact on soil arthropods who comprise an important component of soil food webs. Further, while vegetation has a well-documented influence on soil communities, it is unclear how the plant community might influence their response to altered precipitation. We alte ...

Abstract:
... Estimates of the percentage of species “committed to extinction” by climate change range from 15% to 37%. The question is whether factors other than climate need to be included in models predicting species’ range change. We created demographic range models that include climate vs. climate‐plus‐competition, evaluating their influence on the geographic distribution of Pinus edulis, a pine endemic to ...

Abstract:
... Streamflow drought is a recurring challenge, and understanding spatiotemporal patterns of past droughts is needed to manage future water resources. We examined regional patterns in streamflow drought metrics and compared these metrics to low flow timing and magnitude using long‐term daily records for 555 minimally disturbed watersheds. For each streamgage, we calculated streamflow drought duration ...

Abstract:
... Synchrony defines an organism's overlap with potential resources and mates, essential for survival and reproduction. Flowering synchrony influences gene flow within species and patterns of interaction among plants and with other trophic levels, including pollinators. Climate‐change driven shifts in plant phenology may disrupt plant–plant and plant–pollinator interactions, resulting in reshuffling ...

Abstract:
... The genus Alena Navás, 1916, is considered the most distinct genus of Raphidiidae, because of the uncommon shape of its male genital sclerites and its geographic distribution restricted to the southwestern U.S.A. and western Mexico. Herein, we present a new species of the subgenus Aztekoraphidia U. Aspöck and H. Aspöck, 1970, – Alena (Aztekoraphidia) alanaesp. nov. Based on this discovery we prese ...

Abstract:
... Dryland rivers often harbor abundant populations of nonnative species that threaten native fauna and negatively alter ecosystem structure and function. Native semiaquatic carnivores, such as river otters (Lontra canadensis), that could predate nonnative fauna have been extirpated from many dryland rivers. During 2008–2010, river otters were reintroduced to the Upper Rio Grande (URG), a principal d ...

Abstract:
... Spatial patterns of precipitation in the southwestern United States result in a complex gradient from winter-to-summer moisture dominance that influences tree growth. In response, tree growth exhibits seasonal-to-annual variability that is evident in the growth of whole tree rings, and in sub-annual sections such as earlywood and latewood. We evaluated the influence of precipitation and temperatur ...

Abstract:
... Endosymbiont‐induced cytoplasmic incompatibility (CI) may play an important role in arthropod speciation. However, whether CI consistently becomes associated or coupled with other host‐related forms of reproductive isolation (RI) to impede the transfer of endosymbionts between hybridizing populations and further the divergence process remains an open question. Here, we show that varying degrees of ...

RHDV2 emerged in Europe in 2010 and spread worldwide. During the last 5 years, there have bee ...
