Fossil pollen as a guide to conservation in the Galapagos. by van Leeuwen, J, Froyd, C, van der Knaap, W, Coffey, E, Tye, A, Willis, K

“…Fossil pollen and macrofossils from four sites in the highlands of Santa Cruz Island reveal that all were present thousands of years before the advent of human impact, refuting their classification as introduced species. These findings have substantial implications not only for conservation in Galápagos but for the management of introduced species and pantropical weeds in general.…”

Novel plant–frugivore network on Mauritius is unlikely to compensate for the extinction of seed dispersers by Heinen, JH, Florens, FBV, Baider, C, Hume, JP, Kissling, WD, Whittaker, RJ, Rahbek, C, Borregaard, MK

“…Changes in composition of island frugivore communities may affect seed dispersal within the native plant community, risking ecological shifts and ultimately co-extinction cascades. Introduced species could potentially mitigate these risks by replacing ecological functions of extinct species, but conclusive evidence is lacking. …”

Using multiple palaeoecological indicators to guide biodiversity conservation in tropical dry islands: the case of São Nicolau, Cabo Verde by Castilla-Beltrán, A, Duarte, I, de Nascimento, L, Whittaker, R

“…We analysed how vegetation (abundances in pollen of native and introduced species, and leaf wax n-alkanes), ferns and fungal communities (abundance of non-pollen palynomorphs) varied over time in relation to fire (charcoal concentration) and erosion regimes (grain sizes and elemental composition). …”

Can niche use in red and grey squirrels offer clues for their apparent coexistence? by Bryce, J, Johnson, P, Macdonald, D

“…1. Introduced species are, world-wide, one of the most serious threats to biodiversity. …”

The South Sandwich Islands – a community of meta-populations across all trophic levels by Hart, T, Convey, P

“…Climate change and fisheries will likely impact on the islands’ biota, but we conclude that introduced species pose the largest threat to biodiversity. …”

When is an invasive not an invasive? Macrofossil evidence of doubtful native plant species in the Galapagos Islands. by Coffey, E, Froyd, C, Willis, K

“…In addition to these known introduced species, there are an additional 62 vascular plants classified as "doubtful natives," where native status remains unclear. …”

A global analysis of avian island diversity–area relationships in the Anthropocene by Matthews, TJ, Wayman, JP, Whittaker, R

“…In several cases introduced species seem to have ‘re-calibrated’ the IDARs such that they resemble the historic period prior to recent extinctions.…”

Rapid divergence in physiological and life-history traits between northern and southern populations of the British introduced neo-species, Senecio squalidus by Allan, E, Pannell, J

“…Here, we compare northern and southern populations of the introduced species Senecio squalidus in Britain; S. squalidus has been in southern Britain for approximately 200 years and reached Scotland only about 50 years ago. …”

Discerning the status of a rapidly declining naturalised bird: the Golden Pheasant in Britain by Smith, WJ, Jezierski, MT, Balmer, DE

“…The Golden Pheasant in Britain provides a case study of an introduced species that at first appeared to thrive before declining to the point where no viable wild populations remain. …”

Envisioning the future with ‘compassionate conservation’: An ominous projection for native wildlife and biodiversity by Callen, A, Hayward, M, Klop-Toker, K, Allen, B, Ballard, G, Broekhuis, F, Clarke, R, Clulow, J, Clulow, S, Daltry, J, Davies-Mostert, H, Di Blanco, Y, Dixon, V, Fleming, P, Howell, L, Kerley, G, Legge, S, Lenga, D, Major, T, Montgomery, R, Moseby, K, Meyer, N, Parker, D, Périquet, S, Read, J, Scanlon, R, Shuttleworth, C, Tamessar, C, Taylor, W, Tuft, K, Upton, R, Valenzuela, M, Witt, R, Wüster, W

“…Taken literally, ‘Compassionate Conservation’ will deny current conservation practices such as captive breeding, introduced species control, biocontrol, conservation fencing, translocation, contraception, disease control and genetic introgression. …”

Escape from parasitism by the invasive alien ladybird, Harmonia axyridis by Comont, R, Purse, B, Phillips, W, Kunin, W, Hanson, M, Lewis, O, Harrington, R, Shortall, C, Rondoni, G, Roy, H

“…Our results are consistent with the general prediction that the prevalence of natural enemies is lower for introduced species than for native species at early stages of invasion. …”

Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets by Prendergast, M, Buckley, M, Crowther, A, Frantz, L, Eager, H, Lebrasseur, O, Hutterer, R, Hulme-Beaman, A, Van Neer, W, Douka, K, Veall, M, Quintana Morales, E, Schuenemann, V, Reiter, E, Allen, R, Dimopoulos, E, Helm, R, Shipton, C, Mwebi, O, Denys, C, Horton, M, Wynne-Jones, S, Fleisher, J, Radimilahy, C, Wright, H, Searle, J, Krause, J, Larson, G, Boivin, N

“…These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological and economic impacts of introduced species. Resolution of this longstanding debate requires new efforts, given the lack of well-dated fauna from high-precision excavations, and ambiguous osteomorphological identifications. …”

Exotic or not, leaf trait dissimilarity modulates the effect of dominant species on mixed litter decomposition by Finerty, G, de Bello, F, Bílá, K, Berg, M, Dias, A, Pezzatti, G, Moretti, M

“…This supports the idea that the repercussions of exotic species on ecosystem processes depends on the extent that introduced species bear novel traits or trait values and so on how functionally dissimilar a species is compared to the existing species in the community.…”

Plant toxin levels in nectar vary spatially across native and introduced populations by Egan, P, Stevenson, P, Tiedeken, E, Wright, G, Boylan, F, Stout, J

“…As the first demonstration of large-scale geographic variation and spatial structure in toxic nectar compounds, this work deepens our understanding of the chemical ecology of floral interactions in native and introduced species. Spatially explicit studies of nectar secondary compounds are thus required to show how the extent and structure of spatial variation may affect floral ecology. …”

Cellular compartments cause multistability and allow cells to process more information. by Harrington, H, Feliu, E, Wiuf, C, Stumpf, M

“…Notably, we find that introducing species localization can alter the capacity for multistationarity, and we mathematically demonstrate that shuttling confers flexibility for and greater control of the emergence of an all-or-nothing response of a cell.…”
