The timing of spring warming shapes reproductive effort in a warm-water fish: the role of mismatches between hepatic and gonadal processes
Spring-spawning fishes native to northern environments rely on both increasing temperature and lengthening photoperiod to cue reproduction and may thus be particularly sensitive to rapid warming earlier in the year while day lengths remain short. We investigated the reproductive response of pumpkinseed sunfish Lepomis gibbosus to spring warming commencing at a range of day lengths (9 – 15 hours), corresponding to various calendar days (January 10 – May 22). In both the laboratory and field, both male and female fish that experienced early warming while day lengths were <11 hours: 1) failed to initiate reproductive preparation in the liver before gonad development began, and 2) had reduced reproductive allocation. Analysis of published data on temperate fishes suggested that liver development prior to gonad development is widespread across warm-, cool-, and cold-water thermal guilds, though the precise phenology of liver relative to gonad development appears to vary widely among species. Together, our results point toward dampened reproductive preparation as a novel mechanism mediating reduced reproductive output in both warm- and cool-water fish following earlier spring warming.

Let it snow? Spring snowpack and microsite characterize the regeneration niche of high-elevation pines
<p><b>Aim: </b>The persistence potential of forests under rapid climate change will depend on species-specific tolerances to increasing growing season soil moisture stress as snowpack declines. High-elevation tree species may be particularly vulnerable to increasing water stress and associated changes to disturbance regimes because they occur at the environmental margins of tree distributions and are considered snowpack dependent. Here, we evaluate the interacting effects of climate, disturbance, and microsite conditions on tree regeneration in high-elevation, migration-limited pines that have experienced recent disturbance-induced tree mortality.</p> <p><b>Location</b>: Great Basin (California & Nevada), USA</p> <p><b>Taxon: </b>Gymnosperms; Pinaceae</p> <p><b>Methods:</b> We used field observations from 70 sites that varied in climate, disturbance, and local site conditions across semi-arid, high-elevation forests of the Great Basin. We employed structural equation models to evaluate how climate and disturbance interact with microsite conditions to influence regeneration.</p> <p><b>Results: </b>We found a broad range of establishment conditions of high-elevation conifers - whitebark, limber, and bristlecone pines – across climatic and disturbance gradients in the Great Basin, but our research detected clear differences in the regeneration niche for each species that may lead to differential survival as climate and disturbance conditions continue to change. Regeneration of whitebark and bristlecone pines diverged in their responses to spring snowpack conditions, with whitebark pine increasing and bristlecone pine decreasing with greater spring snowpack. Limber pine regenerated across a range of climatic and landscape conditions, and this generalist strategy may be advantageous if future climate and disturbance conditions exceed tolerances of more specialized species.</p> <p><b>Main Conclusions: </b>Our findings highlight the critical role that spring snowpack, and consequently growing season soil moisture, plays in determining the persistence potential of high-elevation conifers. However, this role varies among species and thus may drive compositional changes as earlier snowmelt drives soil moisture declines across mountainous landscapes of the western United States.</p>

Spring-flowering herbs in North American temperate forests advance their phenology more than trees with warming temperatures
<ol> <li>The phenologies of co-occurring trees and spring-blooming understory herbs in northeastern hardwood forests appear to be regulated by different environmental drivers—air temperature and soil temperature/snowpack, respectively. Accordingly, it has been hypothesized that climate change-driven asymmetry in the advancement of canopy leaf-out relative to the timing of understory growth could reduce photosynthetic rates and reproductive success of understory herbs through greater early-season shading.</li> <li>To determine whether trees and spring-flowering spring-flowering forest herbs are advancing their phenologies at different rates with respect to increasing global temperatures, we examined the phenological responses to warming of 10 species of trees and 11 species of spring-flowering forest herbs (8,045 observations from 965 sites) in northeastern North America using 13 years of data collected by citizen scientists under the auspices of the USA-National Phenology Network.</li> <li>Contrary to expectation, the timing of leaf-out of spring-flowering forest herbs was more strongly associated with temperature than was timing of tree leaf-out, with a mean response rate of −4.9 days/˚C (95% BCI [−5.2, −4.6]) for spring-flowering forest herbs <em>vs.</em> −3.3 days/℃ (95% BCI [−3.5, −3.1]) for trees. However, the response to temperature was not consistent across the latitudinal range, with spring-flowering forest herbs responding more strongly to warming than trees at middle (40–44˚N) and higher (45–48˚N) latitudes but not at lower latitudes (35–39˚N). </li> <li>In contrast to what has been suggested previously, our results suggest that the growing season and carbon uptake of spring-flowering forest herbs could increase as spring temperatures rise. Our study is the first to show spring-flowering forest herbs advancing their phenology at a higher rate than trees with respect to warming.</li> </ol>
