... 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 ...

Abstract:
... AbstractThree sympatric Entomoneis species, found at the same specific locality in Lake Qinghai, China, are studied by using light and scanning electron microscope. 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 ...

Abstract:
... Klasea cerinthifolia (Sm.) Greuter & Wagenitz (Compositae: Cardueae: Centaureinae) is described and illustrated, a full synonymy provided, and its taxonomic position discussed. Cultivation requirements are also outlined and, although apparently unavailable commercially, it may be found in a few botanical gardens. The species exhibits an interesting trimorphic leaf morphology, with the upper caulin ...

Abstract:
... We observed white‐lipped peccaries (Tayassu pecari) killing infant collared peccaries (Pecari tajacu) on the Osa Peninsula of Costa Rica. 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:
... Soundscape comprises of a mix of species-specific calls, where individuals compete for acoustic space, yet a different vegetation structure allows for differential call filtration. We focus on an assemblage of bush cricket species in a human-transformed landscape, with a special focus on the seemingly endangered Thoracistus thyraeus. Landscape transformation produces both novel ecological and acou ...

Abstract:
... I present evidence of sympatric occurrence of two subspecies of Blue-crowned Manakin Lepidothrix coronata in south-west Amazonia. Specimens collected in eastern Acre in Brazil and northern Bolivia, as well as records from south-east Peru, indicate that L. c. exquisita and L c. caelestipileata both occur in the south-east of the Inambari centre of endemism, when compared to their respective holotyp ...

... This study deals with the impact of zinc on the locomotor activity rhythm of two terrestrial isopods Armadillo officinalis and Chetophiloscia elongata. Specimens are collected from the banks of Ghar El Melh lagoon. The locomotor rhythm of untreated and treated individuals with zinc is studied in the laboratory under constant darkness for 10 days. Results showed that untreated individuals of A. off ...

Here we documented up-to-date information on breeding ecology of Buffy Laughingthrush (Garrulax berthemyi), an endemic species of China, and a sympatric coordinal Red-tailed Laughingthrush (Trochalopteron milnei), in southwestern China. Furthermore, we compared breeding ecology of these two sympatric species. No significant differences were found in clutch size, egg size, nest size, nest height, n ...

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 ...

... It is highly challenging to evaluate the species’ content and behavior changes in wild fireflies, especially for a sympatric population. Here, the flash interval (FI) and flash duration (FD) of flying males from three sympatric species (Abscondita cerata, Luciola kagiana, and Luciola curtithorax) were investigated for their potentials in assessing species composition and nocturnal behaviors during ...

Abstract:
... Stenocereus pruinosus and S. stellatus are columnar cacti from central Mexico, distributed in the Valle de Tehuacán and the Mixteca Baja regions. Both species have populations subject to three different forms of human management: wild, in situ and cultivated, growing in sympatry. The objectives of the present study were to compare variation in damage levels, defense mechanisms and fitness componen ...

Abstract:
... If territorial males are able to assess the extent of threat posed by con- and heterospecific intruders in an area of sympatry, they could optimise the expression of territorial behaviour. I broadcast recorded vocalisation types of meadow and rock pipit males in the centre of territories to address the following questions: (1) do meadow pipit males respond to conspecific Soft calls, the (’contact’ ...

Abstract:
... It is widely accepted that anthropogenic climate change is driving species redistribution globally, which would potentially lead to a reshuffling of ecological communities worldwide. Here, we used tuned MaxEnt models to forecast range shifts, changes in species richness and species turnover of the giant panda with its 22 sympatric mammalian species under different future climate change scenarios. ...

Although they differ morphologically, behaviorally, and genetically, the species status of A. laboriosa remains unresolved. We sampled bees in three widely separated regions of Arunachal Pradesh, North East I ...
