The relationships among species' physiological capacities and the geographical variation of ambient climate are key importance to understanding distribution life on Earth. Furthermore, predictions how species will respond change profit from explicit consideration their tolerances. climatic variability hypothesis, which predicts that tolerances broader in more variable climates, provides an analytical framework for studying these between physiology biogeography. However, direct empirical...
The extent to which different kinds of organisms have adapted environmental temperature regimes is central understanding how they respond climate change. Scholander-Irving (S-I) model heat transfer lays the foundation for explaining endothermic birds and mammals maintain their high, relatively constant body temperatures in face wide variation temperature. S-I shows regulated by balancing rates production loss. Both scale with size, suggesting that larger animals should be better cold...
Abstract Aim Physiological traits that approximate the fundamental climatic niche – conditions where a species can survive are outcome of adaptation to environment under historical and current environmental constraints. If large amount variation in physiological among be explained by their phylogeny rather than contemporary conditions, this would indicate phylogenetic conservatism traits, i.e. tendency retain ancestral physiology over time. Here, we evaluate relative contributions explain...
Abstract Rising temperatures are leading to increased prevalence of warm-affinity species in ecosystems, known as thermophilisation. However, factors influencing variation thermophilisation rates among taxa and particularly freshwater communities with high diversity population decline, remain unclear. We analysed compositional change over time 7123 6201 terrestrial, mostly temperate from multiple taxonomic groups. Overall, temperature was positively linked both realms. Extirpated had lower...
Increasing temperatures caused by anthropogenic climate change are leading to changes in the composition of local communities across biomes. This has implications for ecological assessment methods that rely on macroinvertebrates as bioindicators water quality. To investigate influence changing temperature these methods, we analysed macroinvertebrate data from Swiss national monitoring programs. We used a species distribution model simulate effects and estimated resulting three biological...
ABSTRACT Aim Global change can impact the stability of biological communities by affecting species richness and synchrony. While most studies focus on terrestrial ecosystems, our research includes both aquatic realms. Previous works measure overall community synchrony as co‐variation among co‐occurring species, ignoring tail dependence—when fluctuate together at extreme abundance levels. We used time‐series data to test two hypotheses across realms: a positive relationship between diversity...
Abstract Aim To understand how climatic conditions influence the geographical distributions of species and their potential responses to climate change, we investigated relationships between thermal tolerances size limits distributions. We tested two hypotheses for endotherms: variability hypothesis, which predicts increases in range with increasing breadth tolerance, extreme that are related tolerance limits. Furthermore, whether these differ temperate tropical areas. Location Global. Time...
Mechanistic approaches for predicting the ranges of endotherms are needed to forecast their responses environmental change. We test whether physiological constraints on maximum metabolic rate and factor by which can elevate metabolism (metabolic expansibility) influence cold range limits mammal bird species. examine expansibility at boundary (MECRB) species' traits predict variability in MECRB then use as an initial approach project shifts 210 61 find evidence constraints: distributions peak...
Understanding the role of thermal tolerances in determining species distributions is important for assessing responses to climate change. Two hypotheses linking physiology with have been put forward-the climatic variability hypothesis and extreme hypothesis. The predicts selection individuals broad tolerance more variable conditions values under conditions. However, no study has tested predictions these simultaneously several taxonomic groups along elevational gradients. Here, we related...
Active species reintroduction is an important conservation tool when aiming for the restoration of biological communities and ecosystems. The effective monitoring success a crucial factor in this process. Here, we used combination environmental DNA (eDNA) techniques distribution models (SDMs) to evaluate recent reintroductions freshwater fish Alburnoides bipunctatus central Germany. We built SDMs without with eDNA presence data locate further suitable sites potentially overlooked populations...
Abstract Invasive predatory species may alter population dynamic processes of their prey and impact biological communities ecosystem processes. Revealing biotic interactions, however, including the relationship between predator prey, is a difficult task, in particular for that are hard to monitor. Here, we present case study documents utility environmental DNA analysis (eDNA) assess predator–prey interactions two invasive fishes ( Lepomis gibbosus , Pseudorasbora parva ) potential amphibian...
Although Pakistan has rich biodiversity, many groups are poorly known, particularly insects. To address this gap, we employed DNA barcoding to survey its insect diversity. Specimens obtained through diverse collecting methods at 1,858 sites across from 2010-2019 were examined for sequence variation in the 658 bp barcode region of cytochrome c oxidase 1 (COI) gene. Sequences nearly 49,000 specimens assigned 6,590 Barcode Index Numbers (BINs), a proxy species, and most (88%) also possessed...
To study the potential effects of climate change on species, one most popular approaches are species distribution models (SDMs). However, they usually fail to consider important species‐specific biological traits, such as species’ physiological capacities or dispersal ability. Furthermore, there is consensus that does not influence distributions in isolation, but together with other anthropogenic impacts land‐use change, even though studies investigating relative different threats and their...
Metabolic critical temperatures define the range of ambient where endotherms are able to minimize energy allocation thermogenesis. Examining relationship between metabolic and basal rates (BMR) provides a unique opportunity gain better understanding how animals respond varying climatic conditions, especially in times ongoing projected future climate change. We make use this by testing heat dissipation limit (HDL) theory, which hypothesizes that maximum amount species can dissipate constrains...
The ever-increasing human-mediated wildlife reshuffling is raising concern for the conservation of biodiversity. loss biological distinctiveness among regions lessens genetic diversity and consequently evolutionary potential local biotas to tackle present-day global change human disturbance. This process may be sometimes cryptic unless investigated by means a molecular approach. In this respect, game birds are paradigmatic case. black francolin (Francolinus francolinus, Phasianidae)...
Global change alters the stability of biological communities by affecting species richness and how covary through time (i.e., synchrony). There are few large-scale empirical tests stability-diversity-synchrony relationships those mostly focus on terrestrial realm. Moreover, effect synchrony is largely unknown when only at either high or low extremes abundance tail-dependent synchrony), a common phenomenon in ecological communities. Here, we synthesized long-term community time-series data...
The objective of the study is to ascertain genetic variation within Rufous-vented Prinia, Prinia burnesii an endemic species, by DNA fingerprinting applying random amplified polymorphic (RAPD) technique. Genetic material was obtained from three distant sites along western bank River Indus. These include Chashma barrage (32°50’N, 71°20’E), in north; Taunsa (30°45’N, 70°45’E) and southern population Guddu (28°26’N, 69°44’E). In total, 14 RAPD primers were selected determine variability...
Abstract Due to concerns about data quality, McKechnie, Coe, Gerson, and Wolf ( ) questioned the conclusions of our study (Khaliq et al., published in this journal. Here, we argue that most points are fact useful for macrophysiological analyses, mostly because vast majority explicitly reported peer‐reviewed physiological literature. Furthermore, show remain largely robust irrespective inclusion criterion. While think constructive debates adequate use primary meta‐studies as well more...
