{"title":"Gimme Shelter: Refuge Availability Interacts With Conspecific Density and Predator Chemical Cues to Affect Tadpoles and Metamorphs","authors":"Francisco Javier Zamora-Camacho","doi":"10.1111/fwb.70039","DOIUrl":"https://doi.org/10.1111/fwb.70039","url":null,"abstract":"<div>\u0000 \u0000 <p>\u0000 \u0000 </p><ol>\u0000 \u0000 \u0000 <li>Predators may inflict non-consumptive effects on their prey if their presence triggers the expression of defensive traits which consume resources to the detriment of other vital functions. Nonetheless, these effects can be milder if extrinsic factors, either biotic or abiotic, provide antipredator protection.</li>\u0000 \u0000 \u0000 <li>I tested this hypothesis by rearing Iberian green frog (<i>Pelophylax perezi</i> López-Seoane 1885) tadpoles either singly or in groups, exposed or not to predator chemical cues, with or without a refuge. I also studied potential carryover effects of such treatments on the resulting metamorphs.</li>\u0000 \u0000 \u0000 <li>Singly-reared larvae exposed to predator chemical cues grew and swam faster, but group-reared larvae did not follow these trends. Instead, they grew less deep tails as a response to predator chemical cues, which is against the general tendency of most anurans. Irrespective of density, the presence of a refuge induced shorter tails, and when combined with predator chemical cues, slower speed. Development was also faster, and time to metamorphosis shorter in singly-reared individuals under predation pressure. Nonetheless, metamorphs did not follow the same patterns as larvae, and body size and locomotion were at their worst in group-reared individuals which had no refuge while being exposed to predator chemical cues.</li>\u0000 \u0000 \u0000 <li>Therefore, singly-reared larvae exposed to predator cues seemingly invest more in predator avoidance than those reared in a group. Refuges relieve the investment in locomotion. The patterns found in metamorphs, however, suggest the stress resulting from the combination of competition by conspecifics, predation risk and the absence of a refuge echoes after metamorphosis.</li>\u0000 \u0000 \u0000 <li>These results help disentangle the intricate connections between predation pressure as a stressor, refuge as a counter-weight to it and the presence of conspecifics as a source of competition and a relief from pressure at different life stages.</li>\u0000 </ol>\u0000 \u0000 </div>","PeriodicalId":12365,"journal":{"name":"Freshwater Biology","volume":"70 5","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wellman Jr.,&nbsp;Dustin M.

Investigations of fish responses to dam removals have been mostly conducted in the short term and have shown mixed assemblage responses (e.g., increased or decreased species richness following removal). Here, we examined the effects of low-head dam removals on taxonomic composition and functional diversity at a relatively long term (6 years post dam removal). We hypothesised that differential responses of fish assemblages to dam removal are driven by suites of guild and morphological traits and that removal impacts functional complexity, with free-flowing sites having greater distributions of functional diversity than impounded sites.&lt;/li&gt;\u0000 \u0000 \u0000 &lt;li&gt;We conducted our study in the West Fork River, West Virginia, where three low-head dams were removed in 2016. Boat electrofishing surveys were conducted 1 year before the removal (2015) focusing on species of recreational fisheries importance. Then, we conducted surveys in the same sites 6 years after the removal (between September and October 2022). These electrofishing surveys were conducted at sites that were previously impounded but are now free-flowing and those that currently remain impounded by low-head dams.&lt;/li&gt;\u0000 \u0000 \u0000 &lt;li&gt;Results from our univariate and multivariate analyses indicated that current impounded sites and free-flowing sites have statistically distinct taxonomic and functional fish assemblages. Free-flowing sites were associated with overall higher taxonomic richness and greater biomass of some recreationally important species, including muskellunge, smallmouth bass and channel catfish. Conversely, currently impounded sites were associated with lower taxonomic richness and greater biomass of some recreationally important fishes, including green sunfish, bluegill and largemouth bass. Furthermore, functional diversity indices showed high functional richness (FRic) at free-flowing sites, while less evident changes were observed for functional evenness (FEve) and functional divergence (FDiv).&lt;/li&gt;\u0000 \u0000 \u0000 &lt;li&gt;Our findings suggest that long-term changes in the fish assemblages following the dam removals led to greater taxonomic and functional diversity while maintaining fisheries of high recreational importance. While some previous short-term assessments suggested decreased functional complexity shortly after removals, our results suggest increases in functional complexity in the long term. Though dam removals may have high upfront socioeconomic costs, the long-term effects in this study appeared to lead to greater ecosystem function and enhanced recreational opportunities that may outweigh initial costs.&lt;/li&gt;\u0000 &lt;/ol&gt;\u0000 \u0000 ","PeriodicalId":12365,"journal":{"name":"Freshwater Biology","volume":"70 4","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
