Abstract:
... Two species of the Mecyclothorax argutor (Sharp, 1903) species-group, M. neonomassp. nov. and M. brunneonubigersp. nov., are newly described from Mauna Loa volcano on the Island of Hawai‵i. Mecyclothorax neonomas is most similar morphologically to M. swezeyi Liebherr, 2008 of Mauna Kea and is therefore proposed as its adelphotaxon. Conversely, the adelphotaxon proposed for M. brunneonubiger is M. ...

Abstract:
... Communication signals are often key for encoding information on species identity, but determining the features important in conveying those cues is challenging. This is especially the case when attempting to compare across closely related sympatric taxa, where the need for accurate species recognition is critical. We developed an analytical framework to comprehensively quantify the complex movemen ...

Two species are proposed as new to science and named as E. sinensis sp. nov. and E. qinghainensis sp. nov. The third species is identified as E. paludosa (W. Smith) Reimer. Entomoneis sinensis has a linear-lanceolate valve outline and ...

Abstract:
... Skeletal injuries, especially broken bones, diminish physical mobility of animals, and they may affect an individual's ability to obtain food and to evade predators. We quantified and compared healed fractures in two sympatric species of tree squirrels (Sciurus nigerLinnaeus, 1758 and S. carolinensisGmelin, 1788) that differ in body size (mass) and locomotor mode. We assessed the number and locati ...

Abstract:
... Niche theory predicts that to reduce competition for the same resource, sympatric ecologically similar species should exploit divergent niches and segregate in one or more dimensions. Seasonal variations in environmental conditions and energy requirements can influence the mechanisms and the degree of niche segregation. However, studies have overlooked the multi-dimensional aspect of niche segrega ...

Camera trap data indicated high overlap of peccary activity periods, but spatio‐temporal avoidance of white‐lipped peccaries by collared peccaries. Heterospecific infanticide is unknown among ungulates, but could be an important factor in reinforcing niche parti ...

Abstract:
... Seabirds breeding at tropical latitudes suffer an increased pressure to forage efficiently, because oligotrophic waters have less abundant and more patchily distributed prey. In related species living in sympatry, trophic or spatial niche partitioning may emerge as a strategy to mitigate increased competition. However, studies using molecular methodologies such as high-throughput sequencing (HTS) ...

Abstract:
... Species and nestmate recognition in social insects occurs mostly through cuticular hydrocarbons acting as chemical cues. These compounds generate a colony‐specific odor profile depending on genetic and environmental factors. Species and nestmate recognition results in specific behavioral responses, regulating the level of aggression toward other individuals during an interaction. Although species ...
