Abstract:

Abstract Population dynamics are governed by four demographic rates: births, deaths, immigration, and emigration. Variation in these rates and processes underlying such variation can be used to prioritize habitat conservation and restoration as well as to parameterize models that predict habitat-specific effects on population dynamics. The current understanding of patterns of habitat-specific demographic variability in exploited marine species, as well as processes underlying these patterns, was reviewed. We describe patterns of (i) habitat-specific density, followed by ontogenetic changes in

Abstract:

Post-settlement processes can regulate the size and structure of marine invertebrate and fish populations. Faster growth and better physiological condition generally increase the survival potential of early juveniles, being usually associated with structurally complex habitats. Successive cohorts of early juvenile Carcinus maenas were followed in sandy and seagrass (Zostera noltii) habitats in the Mira Estuary, Portugal, to estimate growth and physiological condition (evaluated by RNA/DNA ratio) of juvenile populations. Mean cohort growth was similar in both habitats. However, in the sandy hab

Abstract:

The identification of important spawning and nursery habitats for fish stocks can aid fisheries management, but is complicated by various factors, including annual variation in recruitment success. The alewife ( Alosa pseudoharengus ) is an ecologically important species in Lake Michigan that utilizes a variety of habitats for spawning and early life growth. While productive, warm tributary mouths (connected to Lake Michigan) may contribute disproportionately more recruits (relative to their habitat volume) to the adult alewife population than cooler, less productive nearshore habitats, the ex

Abstract:

Habitats used by the Python (Python bivittatus) were studied in lowland areas of Bardiya National Park, Nepal. The main objective of the study was to assess the specific habitats used by Python in the Park. In association with key informants’ survey to identify the potential habitats areas, field investigation was conducted and found out the specific sites. Among twenty habitat sites of Python, three were currently used and remaining other were found as potential habitats. In total, six specific habitats such as burrow or holes were mostly preferred by Python.ECOPRINT 22: 85-90, 2015

We examined seasonal variation in the spatial distribution and habitat preference of juvenile Atlantic salmon (Salmo salar) in a subarctic river characterized by near-zero water temperatures for 78 months a year. Size-specific differences in habitat use were pronounced in summer but disappeared at the onset of winter, when the habitats preferred by small (≤6 cm) and larger (717 cm) salmon overlapped heavily. Small salmon favoured low-velocity habitats during all seasons, and in summer and autumn they mainly occupied shallow microhabitats along stream margins. In winter and spring, small salm

Abstract:

The blue crab (Callinectes sapidus) is ecologically and economically important in Chesapeake Bay. Nursery habitats, such as seagrass beds, disproportionately contribute individuals to the adult segment of populations. Salt marshes dominated by smooth cordgrass Spartina alterniflora are intertidal nursery habitats which may serve as a refuge from predation for juvenile blue crabs. However, the effects of various characteristics of salt marshes on nursery metrics, such as survival, have not been quantified. Comparisons of juvenile survival between salt marshes and other habitats often employ tet

<strong>Abstract</strong> Background The intensification of agricultural practices over the twentieth century led to a cascade of detrimental effects on ecosystems. In Europe, agri-environment schemes (AES) have since been adopted to counter the decrease in farmland biodiversity, with the promotion of extensive habitats such as wildflower strips and extensive meadows. Despite having beneficial effects documented for multiple taxa, their profitability for top farmland predators, like raptors, is still debated. Such species with high movement capabilities have large home ranges with fluctuation

The species richness of fishes and the distributions of six fish species were compared among four habitat types, snaggy banks, clear banks, mud banks and mid channels, in an estuary in tropical Australia.

On each sampling trip the highest number of species was trapped from snaggy habitats, intermediate numbers from clear banks or mud banks, and the fewest species from mid channels. Although more species occurred in night than in day samples, the pattern of difference among habitats was consistent. T

Abstract:

We studied a fossorial endemic lizard (the sand skink, Plestiodon reynoldsi) to determine habitat structural and vegetation associations in altered habitats at micro-, local, and macroscales. Lizards were present in each of the structural categories and vegetation types we studied, although active orange groves negatively influenced distribution and relative density (determined as the proportion of coverboards within a sampling plot containing signs of sand skink presence). Conversely, relative densities were highest in forested habitats, which contain structural features similar to natural ha

Abstract:

Invasive allochtone species cause the degradation of the natural habitats they invade through the negative impact they have on native plant communities, which they tend to alter, even replace, through their increased competitiveness and their high potential for reproduction and spread. The main objective of the study was to identify and evaluate the spread potential of allochtone invasive species observed in some habitats of European interest in the Pesceana river basin (Vâlcea county), starting from the quantitative evaluation of their populations within the plant associations specific to dif

Abstract:

When monitoring the breeding ecology of birds, the causes and times of nest failure can be difficult to determine. Cameras placed near nests allow for accurate monitoring of nest fate, but their presence may increase the risk of predation by attracting predators, leading to biased results. The relative influence of cameras on nest predation risk may also depend on habitat because predator numbers or behaviour can change in response to the availability or accessibility of nests. We evaluated the impact of camera presence on the predation rate of artificial nests placed within mesic tundra habit

The initial habitat-scale densities of trout were positively related to both depth and cover, although by the end of the experiment, the influence of cover on density was less apparent.

Overall, mysids were concentrated in shallow unvegetated and deep unvegetated estuarine habitats. H. dakini were most abundant in shallow and deep bare habitats at night, whereas R. egregius were most abundant in deep bare habitats during the night. D. aust

Understanding species–habitat relationships is essential for ecosystem-based conservation. This study explores the significance of habitat characteristics and complexity for demersal and benthopelagic communities within a patchwork of coastal habitats, including rocky seabed, macroalgae formations, sandy bottoms, and a combination of rock and sand areas. Species and habitats were surveyed along the north-west (NW) Iberian continental shelf area of Viana do Castelo using baited remote underwater video stations (BRUVS).

Abstract:

Spatial distributions of many tropical trees are skewed to specific habitats, i.e. habitat specialization. However, habitats of specialist species must be divergent, i.e. habitat divergence, to coexist in a local community. When a pair of species specialize in the same habitat, i.e. habitat convergence, they could not coexist by way of habitat specialization. Thus, analyses of habitat divergence, in addition to habitat specialization, are necessary to discuss coexistence mechanisms of sympatric species. In this study, the habitat specialization and habitat divergence along topographic gradient

We monitored demography, movement, and reproductive behavior of gray-tailed voles, Microtus canicaudus, in experimental habitat patches with and without corridors to test the hypotheses that more individuals would move among patches in corridor than in control unconnected habitats, and that individuals would distribute themselves more evenly among patches if corridors were present than if they were not. We predicted that more males than females would move among patches in both treatments and that juveniles in control habitats would exhibit delayed sexual maturation if their dispersal was delay
