Macrobehaviour: behavioural variation across space, time, and taxa

We explore how integrating behavioural ecology and macroecology can provide fundamental new insight into both fields, with particular relevance for understanding ecological responses to rapid environmental change. outline the field of macrobehaviour, which aims unite these disciplines explicitly, highlight examples research in this space. Macrobehaviour be envisaged as a spectrum, where ecologists macroecologists use data borrow tools approaches from one another.

Completing the Speciation Cycle: Ecological Niches and Traits Predict Local Species Coexistence in Birds Across the Globe

Global Ecology and Biogeography, Journal Year: 2025, Volume and Issue: 34(2)

Published: Jan. 30, 2025

ABSTRACT Aim The build‐up of local species diversity requires completing the transition from allopatry to sympatry coexistence (syntopy). However, understanding processes than enable arising in become syntopic remains an unsolved challenge. Potential explanations include niche conservatism, divergence, and energy availability. To gauge their importance, we modelled effects split age, divergence beta alpha niches, specialisation, resource availability reveal factors driving evolution upon speciation. Location Global. Time Period Miocene present. Major Taxa Studied Passerine birds. Methods We collated a dataset 206 passerine sister pairs, each with age divergence; range sympatry; degree syntopy (derived 7,257,312 complete eBird checklists falling within area overlap); (habitats environmental characteristics); (morphology, diet, foraging stratum); ecological specialisation (diet availability; body mass. used phylogeny‐informed models infer which these best explained Results There was major effect conservatism as more similar niches (canopy height, vegetation greenness, moisture availability, habitat affinities) exhibited higher syntopy. Small similarly sized beaks high on diet were also likely coexist locally. In contrast, or overlap stratum) did not predict Confirming previous studies, strongly increased increasing sympatry, while only weakly older pairs. Main Conclusions secondary is driven by mass‐related requirements. Consequently, accumulation richness facilitated both differentiation along various dimensions.

Niche differentiation, reproductive interference, and range expansion

Ecology Letters, Journal Year: 2023, Volume and Issue: 27(1)

Published: Dec. 8, 2023

Abstract Understanding species distributions and predicting future range shifts requires considering all relevant abiotic factors biotic interactions. Resource competition has received the most attention, but reproductive interference is another widespread interaction that could influence ranges. Rubyspot damselflies ( Hetaerina spp.) exhibit a biogeographic pattern consistent with hypothesis limited expansion. Here, we use ecological niche models to evaluate whether this have instead been caused by differentiation. We found evidence for climatic differentiation, encounters least one of narrowest peripheral niches. These findings strengthen case expansion also provide counterexample idea release from negative interactions triggers propose enables expand in while specializing on habitats suitable breeding.

Spatiotemporal dynamics of non-ecological speciation in rubyspot damselflies (Hetaerinaspp.)

Abstract Non-ecological speciation is a common mode of which occurs when allopatric lineages diverge in the absence pronounced ecological differences. Yet, relative to other mechanisms, non-ecological remains understudied. Numerous damselfly clades are characterized as non-adaptive radiations (the result several rounds speciation), but there few for we have detailed understanding spatiotemporal dynamics divergence. Recent phylogeographic analyses demonstrate that American rubyspot damselflies ( Hetaerina americana sensu lato) actually comprise at least two cryptic coexist sympatrically across most Mexico.
