Ecological and evolutionary consequences of metabolic rate plasticity in response to environmental change

Basal or standard metabolic rate reflects the minimum amount of energy required to maintain body processes, while maximum sets ceiling for aerobic work. There is typically up three-fold intraspecific variation in both minimal and maximal rates metabolism, even after controlling size, sex age; these differences are consistent over time within a given context, but plastic can vary response changing environments. Here we explore causes phenotypic at organ, tissue mitochondrial levels. We highlight growing evidence that individuals differ predictably flexibility their extent which they suppress metabolism when food limiting increase capacity high work beneficial.

The Role of Behavioral Ecotoxicology in Environmental Protection

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(9), P. 5620 - 5628

For decades, we have known that chemicals affect human and wildlife behavior. Moreover, due to recent technological computational advances, scientists are now increasingly aware a wide variety of contaminants other environmental stressors adversely organismal behavior subsequent ecological outcomes in terrestrial aquatic ecosystems. There is also groundswell concern regulatory ecotoxicology does not adequately consider behavior, primarily lack standardized toxicity methods. This has, turn, led the exclusion many behavioral studies from chemical risk assessments. To improve understanding challenges opportunities for within toxicology/risk assessment, unique workshop with international representatives fields ecology, ecotoxicology, (eco)toxicology, neurotoxicology, test standardization, assessment resulted formation consensus perspectives recommendations, which promise serve as roadmap advance interfaces among basic translational sciences, practices.

Survival of Eurasian lynx in the human‐dominated landscape of Europe

Conservation Biology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 14, 2025

Abstract Survival and cause‐specific mortality rates are vital for evidence‐based population forecasting conservation, particularly large carnivores, whose populations often vulnerable to human‐caused mortalities. It is therefore important know the relationship between anthropogenic natural causes evaluate whether they additive or compensatory. Further, relation survival environmental covariates could reveal specific landscape characteristics influence demographic performance. We used telemetry data on 681 Eurasian lynx ( Lynx ), a model apex predator with spatial requirements, that were tracked across their European distribution. Through time‐to‐event analyses, we sought determine variables associated differences in survival. Illegal killing was main cause of (33.8%), similar protected hunted (8.6% 7.0% per year, respectively). varied greatly (70–95% year). Across all study sites, higher hunting partially compensated by lower other but not alone. Variation depended sex (female 1.5 times greater than male survival) seasonality (highest risk during season winter), correlated human modification landscapes at both coarse (home range composition) fine (habitat use within home range) scales. Some variation driven unobserved factors, which, given high mortalities, including illegal killing, foremost concern. Due low populations, conclude likely close additive, such maintaining increasing refuge habitat little disturbance critical conservation.

What behavior is important behavior? A systematic review of how wild and zoo-housed animals differ in their time-activity budgets

Natural behavior performance in captive animals is traditionally utilized as a metric to establish welfare states, with an increase natural associated positive welfare. Captive environments, including zoos strive replicate ecologically relevant environments that promote species-specific, adaptive performance. However, spatial restrictions and complex habitats required by some species create various challenges for zoo staff implement management husbandry practices achieve this. Some struggle adapt cope increased abnormal which may reduce Other captivity novel ways, demonstrating flexibility their patterns without compromising research indicating behavioral sparse. The main aim of this review was categorize being fully behaviorally flexible, partially or inflexible. Effect sizes (Hedges’ g) were calculated compare categories the wild zoo, grouped taxonomic Order (Testudines, Primates, Artiodactyla, Psittaciformes Carnivora) ecological traits determine level flexibility. also analyzed behaviors suggestive good absent species. Despite variation across all groups, consistently highest animals, reproductive foraging most often compromised. Overall, complete suggested Testudines (potentially result from temperature maintain homeostasis), completely migratory who are exposed heterogenous landscapes when traveling long distances, specific primate, ring-tailed lemur ( Lemur catta ) potentially improve resource access due terrestrial nature.

Network indicators of cultural resilience to anthropogenic removals in animal societies

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 380(1925)

Published: May 1, 2025

Social learning, information transmission and culture play vital roles in the lives of social animals, influencing their survival, reproduction ability to adapt changing environments. However, effect anthropogenic disturbances on these processes is poorly understood free-living animals. To investigate impact disturbance learning transmission, we simulated individual removal from contact networks derived long-term behavioural datasets. We simulate effects network efficiency for three group-living species-yellow baboons (Papio cynocephalus), African savanna elephants (Loxodonta africana) Indo-Pacific bottlenose dolphins (Tursiops aduncus). reveal how removals key positions reduce efficiency. groups with high levels innovation may cope structures.

Ecological generalism and behavioural innovation in birds: technical intelligence or the simple incorporation of new foods?

Journal of Animal Ecology, Journal Year: 2014, Volume and Issue: 84(1), P. 79 - 89

Published: June 6, 2014

Generalist species are more successful than specialists in anthropogenically modified environments or which they have been introduced, but the nature of link between generalism and establishment success is unclear. A higher feeding innovation rate has previously reported habitat generalist birds from North America. By allowing them to exploit new resources, this might explain generalists' advantage. This result be due generalists being likely find resources because exposed diverse environmental conditions. Alternatively, differ other traits, particular cognitive skills that allow innovate complex food searching handling techniques. To test these hypotheses, we separated avian innovations into a 'technical' (novel behaviour) 'food type' (incorporation species' diet) category. Technical innovations, not type shown correlate with brain size, suggesting reflect ability. We used world-wide data base 2339 recorded literature, covering total 765 assessed correlations size rates on one side diet other. Habitat was positively related rate, technical size. suggests incorporate types their chances environment, opportunism, enhanced skills. In contrast, had rates, as well larger brains, help expand breadth an increase favour evolution abilities.
