Abstract:
... Habitat selection is a fundamental animal behavior that shapes a wide range of ecological processes, including animal movement, nutrient transfer, trophic dynamics and population distribution. Although habitat selection has been a focus of ecological studies for decades, technological, conceptual and methodological advances over the last 20 yr have led to a surge in studies addressing this process ...

Abstract:
... We surveyed the reproductive ecology of Cobitis minamorii minamorii in paddy fields and ditches. The spatial distribution of females in the spawning season differed from that in the non-spawning season, even in short ditches. Eggs were collected in both ditches and paddy fields, unlike an earlier study demonstrating that no eggs were collected in ditches. The frequency distributions of standard bo ...

Abstract:
... Scale and hierarchy have received less attention in aquatic compared to terrestrial systems. Walleye (Sander vitreus) spawning habitat offers an opportunity to investigate scale’s importance. We estimated lake-, transect-, and quadrat-scale influences on nearshore walleye egg deposition in 28 Minnesota lakes from 2016–2018. Random forest models (RFM) estimated importance of predictive variables to ...

Abstract:
... CONTEXT: Area sensitivity, a behaviour whereby smaller patches of habitat are avoided, is of significant conservation concern for North American grassland birds. However, it is unclear whether area sensitivity is caused by patch size per se, or whether it results from factors such as landscape openness, which often covaries with patch size. OBJECTIVES: We aimed to determine which characteristics o ...

Abstract:
... Site fidelity, or the behavior of returning to previously visited locations, has been observed across taxa and ecosystems. By developing familiarity with a particular location, site fidelity provides a range of benefits and is advantageous in stable or predictable environments. However, the Anthropocene is characterized by rates of environmental change that outpace the evolutionary history of exta ...

Abstract:
... Predicting future space use by animals requires models that consider both habitat availability and individual differences in habitat selection. The functional response in habitat selection posits animals adjust their habitat selection to availability, but population-level responses to availability may differ from individual responses. Generalized functional response (GFR) models account for functi ...

Abstract:
... Understanding what fishers know about the ecology of the fish they catch, and how they perceive the state and management of their fisheries can guide efforts towards more sustainable fishing practices. We tested relationships between fishers’ local ecological knowledge (LEK) and their perceptions of their fisheries and of marine protected areas in the Dominican Republic. A qualitative-quantitative ...

Abstract:
... Habitat specialists are particularly vulnerable to extinction when habitat conditions are altered. Information on the habitat use of such species is thus important because it provides insight into factors that influence distribution and abundance, which is crucial for conservation. Here, we aimed to identify factors that influence the patterns of presence and abundance of the Endangered volcano ra ...

Abstract:
... Homosporous club mosses have an archaic life cycle, alternating two locationally, nutritionally, and physiologically independent generations. The sexual generation of club mosses—the gametophytes (or prothallia)—are among the least researched botanical subjects. The gametophytes are responsible for not only sexual reproduction, but also the determination of recruitment of the new sporophyte genera ...

Abstract:
... The roosterfish (Nematistius pectoralis) is a piscivorous predator targeted extensively in recreational fisheries throughout the eastern tropical Pacific; however, its biology is poorly understood. To address these shortcomings, we investigated vertical habitat use and behaviour of roosterfish in coastal Panama using pop-up satellite archival tags. Nearly 5000h of vertical movement data across 274 ...

Abstract:
... The Azores (mid-north Atlantic) has a long history of artisanal multispecific fishery exploiting marine resources around the islands slopes and seamounts. Due to the archipelago´s oceanic character, demersal-deep-sea and pelagic-offshore species are central to local economy. However, a coastal subsistence fishery is also economically and culturally important, as well as understudied, underregulate ...

Abstract:
... Animals may exploit habitat complexity in a myriad of ways, and a widespread pattern of habitat use is vertical stratification. In tropical forests, it often increases niche diversity for frugivorous birds, and it strongly influences seed dispersal and community persistence. Yet, most studies disregard intraspecific variations in the use of forest layers and their ecological and evolutionary conse ...

Abstract:
... Hiking is a natural exercise that has become one the most popular outdoor activities, promoting physical fitness and de-stress without large investments or special equipment. However, hiking has downsides, particularly in the areas in which it takes place. From soil compaction and erosion to disturbance and ecological impacts, mounting evidence shows that it is far from innocuous to ecosystems. De ...

Abstract:
... Bats are among the few mammals that have acquired a sophisticated echolocation ability, attracting considerable attention for their uniqueness. Over the past 50 years, numerous research projects have been designed to study bat echolocation. The overall trend is complex and the dynamics of those publications are difficult to capture. In this study, we conducted quantitative bibliometric analyses of ...

Abstract:
... Reintroducing native carnivores risks creating conflict with people and consequently reducing support for coexistence and conservation efforts. Determining the interface between areas of ecological suitability and conflict risk can help enhance success of carnivore restoration, but this is often difficult because accurate data on risks and tolerance are lacking. Gray wolves (Canis lupus), a focus ...

Abstract:
... Mainstem rivers are important for provisioning cold‐water fisheries and often support fluvial life histories that grow much larger than resident counterparts in tributaries. However, mainstem rivers are also warmer than tributaries during summer and more tightly coupled to regional climate. A key challenge is to understand how fluvial life histories cope with summer temperatures in mainstem rivers ...

Abstract:
... Wind farms may have two broad potential adverse effects on birds via antagonistic processes: displacement from the vicinity of turbines (avoidance), or death through collision with rotating turbine blades. Large raptors are often shown or presumed to be vulnerable to collision and are demographically sensitive to additional mortality, as exemplified by several studies of the Golden Eagle Aquila ch ...

Abstract:
... Fungal endophytes are known to play a vital role in perpetuation and survival of orchids. While orchid–mycorrhizal relationship has been studied in detail, dynamics of orchid–non-mycorrhizal associations are insufficiently explored. There is paucity of empirical evidence for host specificity, phylogenetic preference, co-evolution, and habitat selection amongst orchids and their non-mycorrhizal end ...

Abstract:
... Dam-created reservoirs are common landscape features that can provide habitat for amphibians, but their water level fluctuations and nonnative predators can differ markedly from more natural habitats. We compared fall movement and habitat use by the Oregon Spotted Frog (Rana pretiosa) in the reservoir pool with nearby river and pond habitats at Crane Prairie Reservoir in central Oregon, USA. Movem ...

Abstract:
... The relationship between hydrological variation and the habitat use of waterbirds in wetland complexes is a significant field of ecological research. Quantification of the relationships between wetland hydrological attributes and waterbirds distribution is critical for the success of waterbird conservation. In this study, flood duration (FD) derived from synthetic aperture radar (SAR) imagery was ...
