Conserving lampreys is particularly challenging given their unique life history and propensity for avoiding conventional sampling methods. However, species distribution modeling is an innovative tool that can use historical presence data and spatial data to refine biodiversity monitoring. Here, we created four species distribution models using landscape-scale variables and species occurrence records to predict suitable and unsuitable habitats for extant, native Illinois lampreys. We developed three single-species models and one combined species model that utilized occurrence records from all five extant lamprey species in Illinois. Patterns of suitable and unsuitable habitats for native lampreys indicated similar preferences in habitat. Specifically, maximum temperature values were less than 25 °C and mean soil erodibility was between 0 and 0.5. Urban land cover was in all four models, but the patterns in habitat suitability were not the same across the lamprey species. These models can help natural resource managers prioritize survey sites and determine the contemporary distribution of this imperiled group of fishes.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"3 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, our objectives are to (1) examine the relative abundance of Shortnose Gar <i>Lepisosteus platostomus</i> in the lower Illinois River 1993–2022, (2) estimate the current population structure and vital rates, and (3) estimate the population size through mark-recapture. Estimates of relative abundance were mostly stable or slightly increasing. The total length of Shortnose Gar ranged 30–771 mm and pectoral fin ray ages ranged 1–18 years, with most individuals captured in backwater habitats. Few individuals were recaptured suggesting the possibility of a large population size or a highly mobile population. The mean total length varied among gear types, but gear choice may not have a practical impact on size structure given the high overlap in total length ranges. Pectoral fin ray-derived vital rates suggest that Shortnose Gar in the Illinois River grow slower and have the potential to reach larger body sizes than previously described. Preliminary estimates of mortality rates suggest that fishing mortality remained low for this population as of 2018. The age structure and vital rate findings should be interpreted with caution as pectoral fin rays likely underestimate the age of Shortnose Gar but provide valuable baseline data for future comparisons. Future research should utilize otolith age estimates, determine exploitation levels, and assess movement ecology to better inform management strategies that provide for sustainable harvest of Shortnose Gar.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"15 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we assess potential drivers of the successful invasion of Eastern Banded Killifish, as well as their potential to disrupt native communities and food webs. Specifically, we compare the trophic niche breadth and diet composition between Eastern Banded Killifish and a native subspecies, Western Banded Killifish (<i>Fundulus diaphanus menona</i> Jordan and Copeland 1877), using stable isotope and gut content metabarcoding analyses. Stable isotope analysis showed that Eastern Banded Killifish had a higher variance in littoral dependence and trophic position than Western Banded Killifish, but both stable isotope and gut content metabarcoding analyses revealed an overlap in the diet composition and trophic position between the subspecies. Eastern Banded Killifish may successfully establish outside its native range due to higher feeding variability than Western Banded Killifish, including in habitats historically unused by the native subspecies, but the trophic niche between these two subspecies was similar overall.

They then land on top of the sea surface, displacing water upon contact. At other times, they do not completely clear the water, but partly so, performing a lunge rather than a clear jump or breach. These behaviors have been reported in the scientific literature for the fast-swimming predatory sharks, but also for a slow-swimming planktivorous shark as well as many of the rays. We identify breaching behavior in species in the selachan families, Alopiidae, Carcharhinidae, Cetorhinidae and Lamnidae, and batoidan families, Mobulidae, Aetobatidae, Myliobatidae, Rhinopteridae, and Dasyatidae. We present and discuss evidence in support of the following functions: (1) parasite removal, (2) clearing of gill rakers, (3) expulsion of feces or internal parasites, (4) courtship, (5) attraction of conspecifics, (6) repelled by conspecifics and interpecifics, (7) evasion by conspecifics, (8) feeding, (9) concentrating or stunning of prey, and (10) birthing. Our recording of this behavior has evolved beyond simple observations and now incorporates information gathered through advanced technologies, such as animal-borne data loggers, digital photography, and observations from aerial or underwater drones.

The embryonic development phase is crucial for the preservation and propagation of the Chinese sturgeon, yet the specific influence of water temperature on this process remains inadequately documented. This study conducted experiments using three temperature groups (16, 19, and 22 ℃) to investigate the impact of temperature on the embryonic development of Chinese sturgeon. Subsequently, five statistical models were utilized to fit the developmental data through regression analysis, in order to determine the correlation between incubation time and temperature of the embryos. Data from cultured Chinese sturgeon embryos were finally utilized to validate water temperature development indices. Over the temperature range of 16–22 ℃, water temperature was positively related to the rate of embryonic development in Chinese sturgeon. The time to hatching in the group experiencing the highest temperature (22 ℃) was nearly cut in half in comparison to the group exposed to the lowest temperature (16 ℃).

However, in recent years, noticeable declines in goldeye abundance have led to investigating the current population status along with what factors could be influencing goldeye densities. We sought to examine relative abundance trends from 2014 to 2023 and describe current population dynamics (i.e., size structure, relative weight (<i>W</i>_<i>r</i>), age, growth, and mortality) of these two Missouri River mainstem reservoirs.

Few detailed field investigations on habitat use and thermal occupancy of white sucker exist, limiting our ability to predict the risk of habitat loss from development and climate warming for this cool-water species. Here we investigated seasonal depth, temperature and spatial occupancy patterns of white suckers in a lake located in northern Ontario, Canada. Using a combination of positioning acoustic telemetry and environmental data, we determined depth and space use patterns, seasonal temperature preference indices, and the affinity of white sucker to the lake bottom (i.e., benthic habitat) over a year long period. We found that the white suckers were consistently observed in shallow waters (&lt; 10 m depth) and near the lake bottom across all seasons but were positioned slightly deeper in the winter. The tagged white suckers showed a strong temperature selection preference for thermal habitat between 10 and 16 °C during the open-water seasons and tended to avoid cold (&lt; 6 °C) thermal habitat. Space use patterns, calculated using kernel utilization distributions, and daily movement rates were surprisingly consistent across all seasons, with regular occupancy of only some nearshore areas.
