“…The rose-crowned fruit-dove has been reported as a vagrant species in the Fly River delta region at sea-level. The wompoo fruit-dove is widespread in New Guinea and travels between New Guinea and Australia, but it is restricted to lowland forests from sea level to 1400 m in New Guinea [70]. The diet of the wompoo fruit-dove in New Guinea has been studied and no evidence that it eats Acronychia fruits has been reported [71].…”

Phylogeny of Acronychia (Rutaceae) and First Insights into Its Historical Biogeography and the Evolution of Fruit Characters

BackgroundThe genus Acronychia (Citrus family, Rutaceae) contains 49 species of trees and shrubs that are found mainly in rain forest. The genus has a large distributional range from mainland southern Asia to Australia and New Caledonia, but most species are endemic to either New Guinea or Australia. This study aimed to provide the first detailed molecular phylogeny of Acronychia and use it to test the taxonomic value of fruit morphological characters, and infer the historical biogeography of the genus.MethodologyPhylogenetic analyses (Bayesian Inference, Maximum Likelihood) were undertaken on nucleotide sequence data from two plastid (psbA-trnH, trnL-trnF) and three nuclear markers (ETS, ITS, NIAi3) from 29 Acronychia species (59% of the genus) and representatives of related genera.Results and ConclusionsThe results indicate that the South-East Asian genus Maclurodendron is nested phylogenetically within Acronychia and must be synonymized to render Acronychia monophyletic. Fruit morphological characters have been used previously to infer relationships within Acronychia and our analyses show that these characters are informative for some subclades but are homoplasious for the group as a whole. Apocarpous fruits are the ancestral state in Acronychia and subapocarpous and fully syncarpous fruits are derived. The unisexual flowers of Maclurodendron are derived from bisexual flowers, which are found in all species of Acronychia as well as its relatives. Acronychia probably first evolved on Australia with range expansion to New Guinea via stepping-stone dispersal or direct land connections within the Sahul Shelf, followed by two independent dispersals to areas west of New Guinea. Most species of Acronychia occur in either Australia or New Guinea, but no species occurs in both regions. This is surprising given the close proximity of the landmasses, but might be explained by ecological factors.

“…Regional scale field guide data typically includes extreme records and thus tend to overestimate species’ elevational distributions. To address this issue, I used species’ ‘typical’ elevational distributions presented by Pratt & Beehler (), which represent the elevational zones where species are mostly found. Another potential difficulty in assigning elevational distributions is elevational migration.…”

Thermal tolerances to cold do not predict upper elevational limits in New Guinean montane birds

Aim To test predictions of the ‘fundamental physiological niche’ hypothesis that thermal tolerances are tightly correlated with upper elevational limits in New Guinean montane birds. Location New Guinea. Methods I combined previously published data describing New Guinean montane birds’ (1) metabolic responses to temperature, (2) elevational distributions and (3) recent upslope shifts, with an empirically measured lapse rate (temperature–elevation regression) to test two predictions of the fundamental physiological niche hypothesis – that species’ thermal tolerances to cold temperatures, measured as lower critical temperatures (LCTs) and thermal conductances, are correlated with their upper elevational limits (n = 24 species), and that species’ thermal mismatches (the difference between the mean temperatures species experience at their upper elevation limits and their LCTs) predict the magnitude of recent warming‐associated upslope shifts (n = 11 species). Results Species’ LCTs and thermal conductances were not correlated with the ambient temperatures they experience at their upper elevational limits (cold range limit), and species’ thermal mismatches were not related to the magnitude of recent upslope shifts at their upper elevational limits. Main Conclusions My results do not support the fundamental physiological niche hypothesis and suggest New Guinean montane birds’ upper elevational limits are unlikely to be set by the direct influence of temperature on adult birds’ thermal tolerances. I also found no evidence that warming‐associated upslope shifts in this avifauna are related to species’ thermal physiology. While this result is based on a small sample size, it is consistent with the hypothesis that recent upslope shifts result from biotic factors indirectly related to temperature.

“…During the first afternoon we searched the trail following the ridge above our camp. We were accompanied by five villagers, among them a hunter with bow and arrow, who without prompting had pointed out both A. b. terborghi and A. insignis on the plates in our field guide (Pratt & Beehler 2015). At c.1,570 m he spotted an old tree with a nest hole and after pulling at a rattan growing by the tree, a large, greyish owlet-nightjar flew from the hole and landed above us (at 06°34.035'S, 144°49.177'E).…”
