Abstract Ocean acidification is considered detrimental to marine calcifiers based on laboratory studies showing that increased seawater acidity weakens their ability build calcareous shells needed for growth and protection. In the natural environment, however, effects of ocean are subject ecological evolutionary processes may allow buffer or reverse these short‐term negative through adaptive mechanisms.

Climate change is leading to shifts in species geographical distributions, but populations are also probably adapting environmental at different rates across their range. Owing a lack of natural and empirical data on the influence phenotypic adaptation range marine species, we provide general conceptual model for understanding population responses climate that incorporates plasticity ecosystems.

Abstract Ocean acidification is considered detrimental to marine calcifiers, but mounting contradictory evidence suggests a need revisit this concept. This systematic review and meta‐analysis aim critically re‐evaluate the prevailing paradigm of negative effects ocean on calcifiers. Based 5153 observations from 985 studies, many calcifiers (e.g., echinoderms, crustaceans, cephalopods) are found be tolerant near‐future (pH ≈ 7.8 by year 2100), coccolithophores, calcifying algae, corals appear sensitive. Calcifiers generally more sensitive at larval stage than adult stage. Over 70% in growth calcification non‐negative, implying acclimation capacity acidification. can mediated phenotypic plasticity physiological, mineralogical, structural, molecular adjustments), transgenerational plasticity, increased food availability, or species interactions.

Ecosystems are shaped by complex interactions between species and their environment. However, humans rapidly changing the environment through increased carbon dioxide (CO2) emissions, creating global warming elevated CO2 levels that affect ecological communities multiple processes. Understanding community responses to climate change requires examining consequences of behavioral species, such as those affecting predator prey. underlying sensory process govern these interactions, how they may be affected provides a predictive framework, but many studies examine outcomes only. This review summarizes current knowledge impacts on predator-prey with respect relevant aspects ecology, we discuss potential effects.

Inflexible webs It is clear that human activities are negatively affecting current ecosystems. Predicting how our will affect future systems more challenging because it involves estimating the unknown. Nagelkerken et al. overcame some of these unknowns by constructing small versions, or mesocosms, a marine ecosystem included species representing all trophic levels (see Perspective Chown). They then exposed to predicted carbon dioxide and acidification. The structure was relatively resistant acidification but not warming. Warmed experienced reorganization rescued functional redundancy other stabilizing responses. Such inflexibility may be precursor collapse. Science , this issue p. 829 ; see also 770

ABSTRACT Nitrous oxide (N 2 O) reductase, the sole natural microbial sink for N O, exists in two clades: nosZ I and II. Although previous studies have explored inter‐clade ecological differentiation, intra‐clade variations their implications O dynamics remain understudied. This study investigated both inter‐ differentiation among reducers, drivers influencing these patterns, effects on emissions across continental‐scale river systems. The results showed that II community turnovers were associated with similar key environmental factors, particularly total phosphorus (TP), but variables explained a larger proportion of variation community. influence mean annual temperature (MAT) composition increased more widespread O‐reducing taxa. We identified distinct clusters within each clade reducers observed identical clustering patterns clades. These primarily characterized by MAT regimes, coarse sediment texture as well low TP levels, high abundance producers, MAT‐related constituting predominant proportions. Intra‐clade was crucial predictor flux reduction efficiency. different varying or even contrasting associations dynamics, shared clades exhibited trends. Low‐MAT communities negatively correlated denitrification‐normalized O:(N + ) ratio, whereas high‐MAT positive correlations. pattern likely stems from low‐MAT being better adapted to eutrophic conditions frequent co‐occurrence O‐producing genes. findings advance our understanding distribution functions ecosystems, suggesting warming rivers may decreased efficiency thereby amplify temperature‐driven emissions.

Abstract Ecologically dominant species often define ecosystem states, but as human disturbances intensify, their subordinate counterparts increasingly displace them. We consider the duality of disturbance by examining how environmental drivers can simultaneously act a stressor to and resource subordinates. Using model ecosystem, we demonstrate that CO 2 ‐driven interactions between account for such reversals in dominance; i.e., displacement dominants (kelp forests) subordinates (turf algae). established enrichment had direct positive effect on productivity turfs, negligible kelp. further suppressed abundance feeding rate primary grazer turfs (sea urchins), an opposite minor (gastropods). Thus, boosted production producers, exacerbated net reduction its consumption grazers, accounts community change (i.e., turf displacing kelp). Ecosystem collapse, therefore, is more likely when alters competitive dominance consumers fail compensate. By recognizing responses interacting disturbance, which may stabilize or exacerbate change, begin understand intensifying determine whether not ecosystems undergo phase shifts.
