Across the coastal marsh-forest ecotone, there are stark shifts in two vital conditions for plants: salinity and light availability. We measured these abiotic conditions and plant productivity at sites spanning the ecotone and within a forest clear-cut, where canopy shading had been experimentally removed. In a greenhouse manipulation of plant species neighbor, salinity, and light availability, we hypothesized that plant interactions would become more facilitative in stressful conditions and that more salt tolerant species would also be more light-demanding. Species salt tolerance followed an expected ranking based on species zonation in the field, but all species responded similarly to reductions in light. Plant interactions in all treatments were negative or neutral, never facilitative. Despite low resource availability of light and elevated levels of salinity within the marsh-forest ecotone, plant interactions there reflect a benign stress environment, in which competition is predominant and where resource limitation, stress, and competition have additive, negative effects on plant performance.</div></div>","PeriodicalId":100260,"journal":{"name":"Climate Change Ecology","volume":"9 ","pages":"Article 100095"},"PeriodicalIF":0.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the ability to simulate real world conditions in the laboratory can be a barrier to prediction accuracy. We performed a systematic review of experimental coral bleaching literature and assembled a database to identify the methods used to measure bleaching in heating experiments and assess how closely heating experiments resembled marine heatwaves (MHWs) on coral reefs. Observations of the maximum photochemical yield of Photosystem II (<em>F</em><sub>V</sub>/<em>F</em><sub>M</sub>), though not a direct measure of dysbiosis, vastly outnumbered Symbiodiniaceae density and chlorophyll observations in the reviewed literature, indicating its widespread misuse as a proxy for coral dysbiosis. Laboratory studies in our database used higher maximum temperatures (∼ 0.9 ×), degree heating times (∼ 1.7 ×) and heating rates (∼ 7.3 ×), and shorter durations (∼ 1.5 ×), than MHWs on coral reefs. We then asked whether exposure differences between laboratory experiments and reef conditions altered the relationship between coral dysbiosis and heating metrics using the example of hormesis. We fit curves on the data both with and without ecologically relevant heating metrics and found hormetic curves in some response variables that were altered with the exclusion of exposures that fell outside of the bounds of MHWs on coral reefs, indicating a high likelihood of prediction error. We recommend that laboratory-based studies of coral dysbiosis use ecologically relevant exposures to improve predictions of the physiological response of corals to our rapidly warming oceans.</div></div>","PeriodicalId":100260,"journal":{"name":"Climate Change Ecology","volume":"10 ","pages":"Article 100094"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144107235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that climate change-induced shifts in growing season temperature, early growing season precipitation, and snow residence time (SRT) would impact growth rate and asymptotic size in the threatened Eastern Massasauga (<em>Sistrurus catenatus</em>) rattlesnake. We used capture-mark-recapture data from eleven sites across the species’ range to fit a set of non-linear models evaluating the effects of these three climate variables on asymptotic size and growth coefficient in a modified von Bertalanffy growth curve. We found that longer SRT resulted in larger asymptotic size. We also found support for both a negative relationship between SRT and growth rate and a positive relationship between precipitation and growth rate. We averaged all supported models and predicted growth and size in the 2080s under a stabilization (RCP 4.5) and a high (RCP 8.5) emission scenario. Under RCP 8.5, predicted increases in female growth rate ranged from 10 % to 33 %, whereas decreases in female size across sites ranged from 9 % to 17 %. Under this scenario female lifetime reproductive success will decrease, as faster growth is associated with increased mortality, early senescence, and poor offspring quality, and smaller body sizes will result in smaller and fewer young.</div></div>","PeriodicalId":100260,"journal":{"name":"Climate Change Ecology","volume":"9 ","pages":"Article 100091"},"PeriodicalIF":0.0,"publicationDate":"2024-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143175445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calcifying organisms like CCA are particularly susceptible to ocean acidification (OA), and settlement behavior of larvae may be compromised as seawater temperatures increase (ocean warming; OW) and pH levels decrease as a result of climate change.

However, net calcification rate was reduced in <em>H. boergesenii</em> but not <em>Pa. solubile</em> after exposure to future seawater conditions.

A failure to synchronize parturition with the advancing spring flush of resources can lower reproductive fitness; on the other hand, a longer growing season could be beneficial to some species.

Using 29 years of wildlife motor-vehicle accident data (1988–2016) as an index of deer rut behaviour in southern Ontario, Canada, we assessed four deer management areas (DMAs) to determine: 1) whether timing of the white-tailed deer rut has changed; 2) whether the growing season has changed; and 3) whether changes in growing season and rut are correlated. We found that in the southwestern-most DMA the peak of the rut is 9 days earlier than in the northeastern-most DMA. The peak of the rut did not change over three decades. We detected an increase in the number of growing degree days, signifying both an earlier start to spring green-up and a later end to fall.
