Abstract Both community composition changes due to species redistribution and within-species size shifts may alter body-size structures under climate warming. Here we assess the relative contribution of these processes in community-level body-size changes in tropical moth assemblages that moved uphill during a period of warming. Based on resurvey data for seven assemblages of geometrid moths (>8000 individuals) on Mt. Kinabalu, Borneo, in 1965 and 2007, we show significant wing-length reduction (mean shrinkage of 1.3% per species). Range shifts explain most size restructuring, due to uphill shifts of relatively small species, especially at high elevations. Overall, mean forewing length shrank by ca. 5%, much of which is accounted for by species range boundary shifts (3.9%), followed by within-boundary distribution changes (0.5%), and within-species size shrinkage (0.6%). We conclude that the effects of range shifting predominate, but considering species physiological responses is also important for understanding community size reorganization under climate warming.

Thaumastus caetensis Pena, Salgado and Coelho, 2011 is a recently described species from Serra da Piedade (19°49’19” S, 43°40’46” W), Caeté municipality, Minas Gerais, southeastern Brazil. We present a new record of this species based on a young specimen collected in the highlands of Reserva Particular do Patrimônio Natural Santuário do Caraça, at Serra do Caraça (20°08’04” S, 43°27’09” W). This species is probably restricted to the “campos rupestres”, above 1,400 m above sea level and the new record represents the only known protected occurrence within the species’ range.

We report the first records of Semomesia geminus (Fabricius, 1793) from Rio de Janeiro (RJ) and Pernambuco (PE) states, expanding the known species range (Bahia-BA, Espírito Santo-ES and Minas Gerais-MG states) 700 km further south and 1200 km north of typical localities in ES. The taxon was photographed twice in Reserva Ecológica de Guapiaçu (REGUA) and two additional RJ specimens have since been located in museum collections. A distribution map build upon specimens’ label data is presented and a much wider range extension revealed and discussed. Observations on its perching habits, with potential taxonomic significance, are supplied.

The Impact

Of the 207 breeding species considered in Lithuania, results of the review show that with a north-easterly shift in their range, the 33 (16%) species breeding on the western, south-western and southern peripheries of their total species range may be significantly affected and are likely to become extinct in the region. Species in different habitat types may suffer differently, the most vulnerable bird species being those breeding in wet habitats. By contrast, communities in dry habitats hold the least number of potentially vulnerable breeding species. The remaining 174 species (84%), those with their breeding populations in the northern, north-eastern, eastern and north-western peripheries of their ranges and in the central part of species range, may benefit from climate warming and are unlikely to become extinct. The patchiness of the breeding range, the species breeding in wet habitats and the position of the southern, south-western and western peripheries of the entire species range are shown to be directly interconnected and, with further climate warming throughout the 21st century, these Lithuanian breeding species are likely to face the greatest risk of extinction. Additionally, climate change may not be the only threat to the species due to other factors, such as changes in land use. Bird diversity variation under the impact of climate change is a serious problem facing the world and we must find new effective measures of bird protection. Santrauka Apžvalga parodė, kad iš 207 Lietuvoje perinčių paukščių rūšių, jų arealams traukiantis šiaurės rytų kryptimi, 33 (16%) rūšių populiacijoms, perinčioms rūšies arealo vakarinėje, pietvakarinėje ir pietinėje periferijose, gresia pažeidimai, jos gali išnykti. Su įvairiomis buveinėmis susijusios rūšys gali patirti skirtingą žalą, iš jų labiausiai pažeidžiamos šlapiosiose buveinėse perinčios rūšys. Sausųjų buveinių bendrijų galimai pažeidžiamų rūšių skaičius, priešingai, mažiausias. Kitoms 174 rūšims (84%), kurių perinčios populiacijos yra rūšies arealo šiaurinėje, šiaurės rytinėje, rytinėje ir šiaurės vakarinėje periferijoje ir arealo centrinėje dalyje, klimato šilimas gali turėti teigiamos įtakos, tad jos neturėtų išnykti. Nustatyta, kad perėjimo arealo fragmentiškumas, paukščių perėjimas šlapiuosiuose biotopuose bei rūšies arealo vakarinėje, pietvakarinėje bei pietinėje periferijose yra tarpusavyje artimai susiję, ir, klimatui 21 amžiuje toliau šylant, šios Lietuvoje perinčios rūšys turėtų patirti didžiausią išnykimo pavojų. Be to, klimato kaita nėra vienintelis rūšių išnykimo pavojus, nes čia veikia ir kiti veiksniai, tokie kaip žemėnaudos pokyčiai. Paukščių įvairovės kaita keičiantis klimatui visame pasaulyje aktuali problema. Būtina ieškoti sprendimų, kaip sumažinti paukščiams kylantį pavojų, atsižvelgiant į rūšių biotopų pasirinkimo ekologijos specifiškumą, regioninius klimato kaitos pokyčius ir mastą, siekti pasirinkti efektyvius paukščių apsaugos ir paukščių rūšių reguliavimo būdus.

Mitochondrial Dna Analysis

A fauna survey was conducted within the Throssell and Broadhurst Ranges in the Little Sandy Desert Bioregion of Western Australia during August and September 2012. The endangered northern quoll (Dasyurus hallucatus) was recorded from two distinct locations of similar habitat: deep dissected rocky gorges containing caves and permanent waterholes. One individual was photographed by a motion-sensitive camera and several scats were collected, with mitochondrial DNA analysis confirming the identification. These records represent a significant range extension (~200 km) and due to habitat restrictions are likely to represent the very eastern extreme of the species’ range.

Dispersal Distances

Rapid rates of species range extension during the Holocene represent seed dispersal distances of at least 6 to 8 km per generation for North American species of Fagus, Quercus, and Carya, taxa whose fruits are heavy nuts. Occasional seed dispersal by biotic seed predators is necessary for these dispersal distances. One likely agent for dispersal across long distances and habitat discontinuities was the extinct (since 1914 A.D.) passenger pigeon (Ectopistes migratorius). This bird's abundance, capacity for delayed digestion, and nomadic habits strongly suggest an occasional seed dispersal role, although a coevolutionary seed dispersal relationship cannot be inferred from available evidence. The capacity of some heavy seeds for dispersal distances greater than those of most light, wind-dispersed seeds has biogeographic and genetic implications.

Perithemis Tenera

Climate warming is accepted as an explanation for the recent appearance of Blue Dasher, Pachydiplax longipennis (Burmeister, 1839), and Eastern Amberwing, Perithemis tenera (Say, 1839), in the Ottawa region, as this range expansion meets 6 criteria: (1) the climate in the newly occupied territory has warmed sufficiently to allow colonization; (2) a new range expectation based on the amount of climate warming is met; (3) other factors potentially promoting spread are excluded; (4) the possibility that range extension is a result of difficulty of observation and/or insufficient fieldwork in earlier times is excluded; (5) there is ample evidence for establishment; and (6) spread has been in the direction of the warmer territory or within it. By 2000, the mean daily temperature in the Ottawa region had increased by about 2°C since 1880 and about 1.1°C since 1960. This would allow new zonal boundaries and the prediction of expansion from a well-defined and long-occupied area into the Ottawa Valley. The two species entered this region in 2008–2012 and, subsequently, became well established.

The Family

Morunasaurus is a genus of Neotropical iguanid lizards of the family Hoplocercidae, inhabiting Central and northwestern South America. Their phylogenetic relationships are not completely clear but being presumably paraphyletic. Its type species, M. groi, is very rare, known only from two single localities and a handful of specimens. Here I report a new occurrence of this species for Colombia, which constitutes the southeastern record to the date, extending the species range by about 175 km and 510 m altitudinally. Additionally, I discuss about the intraspecific differences in coloration between Panamanian and Colombian specimens.
