Hand-Wing Index as a surrogate for dispersal ability: the case of the Emberizoidea (Aves: Passeriformes) radiation

Biological Journal of the Linnean Society, Journal Year: 2022, Volume and Issue: 137(1), P. 137 - 144

Published: July 1, 2022

Abstract Measuring the dispersal ability of birds is particularly challenging and thus researchers have relied on extended use morphological proxies as surrogates for such ability. However, few studies tested relationship between other dispersal-related traits. In this study, we test most commonly used proxy dispersal—the Hand-Wing Index (HWI)—with traits highly associated with abilities, geographic range size, migratory behaviour distances. We Emberizoidea superfamily to evaluate these relationships measured HWI 2520 individuals from 431 species (almost half all in superfamily). first estimated phylogenetic signal searched best evolutionary model explain its variation. then performed PGLS analyses assess abilities. Our results showed that has a strong positively related findings support viable birds.

Movement Ecology of Adult Western Corn Rootworm: Implications for Management

Movement of adult western corn rootworm, Diabrotica virgifera LeConte, is fundamental importance to this species’ population dynamics, ecology, evolution, and interactions with its environment, including cultivated cornfields. Realistic parameterization dispersal components models needed predict rates range expansion, development, spread resistance control measures improve pest management strategies. However, a coherent understanding rootworm movement ecology has remained elusive because conflicting evidence for both short- long-distance lifetime dispersal, type dilemma observed in many species called Reid’s paradox. Attempts resolve paradox using genetic strategies estimate gene flow over space likewise imply greater distances than direct observations short-range suggest, Slatkin’s Based on the wide-array available evidence, we present conceptual model under premise it partially migratory species. We propose that populations consist two behavioral phenotypes, resident migrant. Both engage local, appetitive flights, but only migrant phenotype also makes non-appetitive resulting patterns bimodal resolution paradoxes.

Seasonal migration and the evolution of an inverse latitudinal diversity gradient in shorebirds

Abstract Aim While the evolution of seasonal migration and its association with biogeography have been subject numerous studies, influence on species diversification has rarely examined. The aim this study is to explain atypical latitudinal diversity gradient in shorebirds: did evolve from higher situ or repeated transitions? Location Global. Time Period Palaeogene present. Major Taxa Studied Order Charadriiformes (shorebirds allies). Shorebirds include longest annual migrations birds exhibit an inverse gradient, more breeding toward latitudes. Methods We first assessed temporal geographical framework using a newly reconstructed time‐calibrated phylogeny, fossil record as complementary source information. then used hidden state speciation extinction models test whether thus shaped by migratory behaviour distribution. Results found that ancestor was likely tropical year‐round resident current clade's distribution not dispersal events out tropics but rather temperate biomes compared biomes. Seasonal affect rate our models. However, seems be prerequisite breed biomes, indirectly enabling observed Main Conclusions Our results bring original insights into how acted precursor biogeographical history large bird clade, ultimately shaping gradient.

An integrative modelling framework for passive acoustic telemetry

Abstract Passive acoustic telemetry is widely used to study the movements of aquatic animals. However, a holistic, mechanistic modelling framework that permits reconstruction fine‐scale and emergent patterns space use from detections at receivers remains lacking.

Size-driven parr-smolt transformation in masu salmon (Oncorhynchus masou)

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Oct. 3, 2023

Anadromous salmonids exhibit partial migration, where some individuals within a population migrate down to the ocean through complex interactions between body size and photoperiod. This study aimed integrate ontogenetic seasonal patterns of smoltification, series changes for future marine life, in strain masu salmon (Oncorhynchus masou). Spring as evidenced by activation gill Na+,K+-ATPase (NKA), was induced during winter under an advanced In addition, juveniles showed additional peak NKA activity August regardless When juvenile were subjected feeding manipulations first spring/summer, only fish exceeding fork length 12 cm exhibited increased activity. We tested whether size-driven smoltification required long-day period exposing constant short-day (9-h light 15-h dark) from January November. Juveniles conditions exceeded June but no signs smoltification. Thus, undergo photoperiod-limited, summer size-limited, photoperiod-driven following spring. The findings present provide framework further elucidation physiological mechanisms underlying migration salmonids.

Winter locations of red‐throated divers from geolocation and feather isotope signatures

Abstract Migratory species have geographically separate distributions during their annual cycle, and these areas can vary between populations individuals. This lead to differential stress levels being experienced across a range. Gathering information on the used cycle of red‐throated divers (RTDs; Gavia stellata ) has become an increasingly pressing issue, as they are concern when considering effects disturbance from offshore wind farms associated ship traffic. Here, we use light‐based geolocator tags, deployed summer breeding season, determine non‐breeding winter location RTDs locations in Scotland, Finland, Iceland.

Abstract Animal migration impacts organismal health and parasite transmission: migrants are simultaneously exposed to parasites able reduce infection for both individuals populations. However, these dynamics difficult study; empirical studies reveal disparate results while existing theory makes assumptions that simplify natural complexity. Here, we systematically review of across taxa, highlighting key gaps in our understanding. Next, develop a unified evolutionary framework incorporating different selective pressures parasite–migration interactions accounting ecological complexity goes beyond previous theory. Our generates diverse migration–infection patterns paralleling those seen systems, including partial differential migration.

Long-distance movement dynamics shape host microbiome richness and turnover

FEMS Microbiology Ecology, Journal Year: 2024, Volume and Issue: 100(7)

Published: June 8, 2024

Abstract Host-associated microbial communities are shaped by host migratory movements. These movements can have contrasting impacts on microbiota, and understanding such patterns provide insight into the ecological processes that contribute to community diversity. Furthermore, long-distance new environments anticipated occur with increasing frequency due distribution shifts resulting from climate change. Understanding how hosts transport their microbiota them could be of importance when examining biological invasions. Although well-documented, underlying mechanisms lead restructuring these remain relatively unexplored. Using literature simulations, we develop a framework elucidate major factors We group two types—regular (repeated/cyclical movements, as found in many birds mammals) irregular (stochastic/infrequent do not cyclical basis, insects plants). Ecological simulations prior research suggest movement type frequency, alongside environmental exposure (e.g. internal/external microbiota) key considerations for movement-associated changes. From our framework, derive series testable hypotheses, means test them, facilitate future dynamics.
